Rubicon is partnering with Sato to amplify what matters most: deep liquidity, fresh trading volume, and aligned incentives that reward the community driving it all forward!

🤝 The Partnership

Sato The Dog is a fast-growing memecoin and emerging cultural symbol on Base. With a robust community, rich lore, and unique positioning, $SATO has quickly become one of the most recognized projects in the Base ecosystem.

In collaboration with Rubicon, Sato The Dog has committed 600 million $SATO to deepen liquidity, drive volume, and energize community participation. This is a high-energy, high-alignment integration designed to deliver lasting value to both ecosystems.

This campaign includes:

• 600M $SATO allocated to incentivize farming and trading activity

• $RUBI rewards for swapping and/or trading $SATO

• Incentives across two pairs: SATO/WETH and SATO/USDC

• Ongoing marketing collaboration including contests, AMAs, and creative activations

All $SATO incentives are deployed transparently, live onchain.

⚙️ How It Works

$SATO is now a live, incentivized trading asset on Rubicon. You can:

• Earn $SATO by LPing and staking on the selected pairs (SATO/WETH and SATO/USDC); add a new liquidity position and stake for rewards at app.rubicon.finance/liquidity

• Earn $SATO by trading either pair and climbing the volume leaderboard at app.rubicon.finance/leaderboard/sato

• Also earn $RUBI when trading, swapping, or LPing $SATO

• Swap, stake, and farm directly from the Rubicon app

Trading fees generated by Rubicon Aquila flow to the Rubicon DAO as protocol-owned liquidity.

🐾 What This Unlocks

Memecoins are culture. And culture drives liquidity. Rubicon is proud to support $SATO as one of the first memecoins in Base's ecosystem to embrace coordinated, onchain incentive design.

This partnership strengthens:

• $SATO’s market depth and liquidity

• Cross-community awareness and engagement

• The overall Base ecosystem’s DeFi footprint

With a dedicated leaderboard, continuous rewards, and fun-first marketing, we’re setting the stage for maximum traction across the board.

🪙 Start Farming. Start Trading. Start Earning.

Ready to earn? Provide liquidity to the incentivized $SATO pools or trade $SATO directly in our app—both qualify for rewards through $SATO and $RUBI incentives on every eligible trade.

Ad Victoriam.

Rubicon exists to build the World’s Last Financial Exchange — a decentralized, non-custodial trading platform that democratizes access to global markets. Our mission is to accelerate the advent of an open, efficient, and transparent financial system for humanity, governed and operated by its users.

Over the past four years, Rubicon has processed over $200 million in onchain trading volume across many protocol versions. Every trade has been non-custodial, verifiable, and settled onchain.

In a world where traditional finance is dominated by gatekeepers, and much of crypto remains opaque or centralized, Rubicon offers something fundamentally different: an open trading system, fully onchain and governed by its community.

At the heart of that system is $RUBI — a utility governance token and the root of protocol control. $RUBI is a direct fork of Aave V2 governance, deployed on Ethereum. Governance is live, onchain, and publicly verified.

🎁 Claim Live: 4% of Supply to 273k+ Historical Users

We are airdropping 4% of the total $RUBI supply to over 273k historical users who meaningfully used the protocol across its lifecycle.

Claim is live now on Base:

👉 app.rubicon.finance/rewards

This is a live onchain airdrop. **USE OR INVEST AT YOUR OWN RISK - $RUBI IS A UTILITY GOVERNANCE TOKEN FOR ONCHAIN VOTING AND DECENTRALIZATION. There are many risk warnings across our web properties and massive risks that Rubicon faces, this can all go to zero - only use or invest what you can afford to lose on Rubicon; all users agree to our TERMS OF SERVICE.**

To our community: thank you. If you missed this one, please note that 66% of the total supply will be for future airdrops and incentives to users!

⚙️ The Product: Trading for the Open Internet

Rubicon is a powerful onchain trading platform — optimized for ERC-20s and live today on Base, Ethereum, Optimism, and Arbitrum. We’ll expand to other chains in the future. Our origins are on Optimism, whom we love and respect for their support.

The protocol can be described as the legendary triple stack — a three-layer system that ensures users get the best price possible for their swap or trade, and that LPs and market makers can earn in a variety of ways, provisioning liquidity. There are extensive details about the smart contracts and architecture of the Rubicon protocol in our docs.

💠 1. Gladius – Aggregator Layer

RFQ auctions across the open internet. Your order is filled by Rubicon liquidity if we have the best price. Otherwise, we route it externally - game theory and cryptography guarantee users get execution only on their terms at the best price possible. Totally non-custodial, permit2 signature-based, and gasless swap execution.

🏛 2. Classic – Onchain Order Book

The original Rubicon system. Public, performant, and live since 2021. Fully onchain ERC20 limit order book.

🌀 3. Aquila – Uniswap V2 Fork

A passive liquidity layer for composability and simple LPing.

All unified under one interface. All built for speed, scale, and sovereignty.

🪙 $RUBI Distribution Overview

The $RUBI token enables decentralized governance and long-term alignment between the protocol and its community. It is a fork of AAVE v2 Governance.

Total Supply: 10 Billion $RUBI

🧑‍🤝‍🧑 70% — Community Allocation

• 4% — Historical Airdrop

  • Classic (16%): Usage of Rubicon’s onchain order book, favoring maker volume.

  • Gladius (20%): Volume swapped or traded through the offchain Gladius RFQ system.

  • Aquila (1%): Trading activity on Aquila historically, on select pairs.

  • Pools (3.5%): Liquidity provision, weighted by time and value.

  • Lazarus (32.95%): Users who lost funds in the 2021 Rubicon Pools exploit on Optimism (an OLD, no longer used liquidity experiment from our origins). This is our second and final airdrop to this cohort — after tens of thousands of OP were previously distributed in prior airdrops.

  • OP Rewards (24.55%): Time-weighted recipients of OP during Rubicon’s rewards programs that have continued since the summer of 2023 and our initial grant. Many tens of thousands of OP have been paid to our community thanks to Optimism.

  • Promo NFT (0.0005%): Honoring a commitment we made to those who participated in a one-off, Galxe contest for The Big Guy memecoin.

  • Community (2%): Stand-out community members. These are people in discord who have earned “Centurion” status and have helped Rubicon over the years with feedback, memes, and dreams.

• 66% — Long-Term Emissions

  • Emitted monthly over 16 years, with allocation actively managed by the DAO. Note, that this 16-year linear vest is irrevocable and commenced. All distributions are voted through Governance.

  • The goal is simple: optimize liquidity and volume growth while funding public goods, contributors, and ecosystem expansion. Directly incentivize usage and activities that build the DAO community treasury and Rubicon.

  • The only fixed portion at launch is 6 months of upfront LP rewards:

    • RUBI/USDC LPs: 7.5% of monthly emissions - funded and live yield farming on Base!

    • RUBI/WETH LPs: 17.5% of monthly emissions - funded and live yield farming on Base!

  • The remaining 75%+ is retroactively distributed based on volume, usage, and community proposals, including:

    • Trading volume on Gladius and Aquila

    • Strategic partnerships

    • User acquisition programs

    • B2B integrations

    • Awareness campaigns

  • Rewards are visible and trackable through the live leaderboard:

    https://app.rubicon.finance/leaderboard

  • The DAO will refine and update this distribution dynamically — rewarding where it works, cutting where it doesn't. This is a live, collaborative system coordinated in the Forum.

🔐 30% — Insider Allocation

• 19.5% — DevCo Grant (Unlocked)

  A one-time grant to the protocol’s DevCo multisig to fund long-term development, research, and help foster decentralization.

• 10.5% — Contributor Vesting

  Founding insider individuals. Onchain, long-term aligned. 6–12 month cliffs, 3–4 year terms. Fully auditable. These tokens are going to team members who have dedicated years of their working life to Rubicon, and hopefully will build with us for many to come.

💧 Protocol-Owned Liquidity

Rubicon’s DAO will pursue protocol-owned liquidity as a core strategy.

Rather than rely on mercenary capital, Rubicon aims to become its own liquidity provider. Over time, the DAO will accumulate LP tokens, ERC-20s, and productive onchain assets — deployed via onchain governance. The founding DAO treasury strategy is to capture as many fees as possible and build massive LP positions to support the DAO onchain - TLDR: DAO should stack LPs.

This stands in stark contrast to the GameStop / Robinhood crisis, where centralized platforms shut down access to protect private market makers.¹ On Rubicon, that is impossible — and over the long term, we aim to build liquidity that cannot be censored and backstops the ecosystem forever.

¹ Footnote: See “The Antisocial Network” by Ben Mezrich for more

🏛 Founding Principles of the Rubicon DAO

The DAO is governed by four core principles:

1. Long-Termism

We build on an infinite time horizon. The 16-year emission curve aspires to this end. Rubicon is the infinite liquidity stack for the infinite machine.

2. Frugality

We turned down Y Combinator in 2021. We bootstrapped Rubicon from scratch without VC capital through the down market and lots of pain. This enabled us to Fair Launch 70% of tokens to users. The DAO must remain lean, efficient, and sovereign - only the paranoid survive.

3. Fundamentals

The treasury should stack LP tokens, crypto coins, and RWAs. Liquidity is strength. Value compounds.

4. Continuous Improvement

Compounding works. 1% better every day → 30× stronger in a year. Extrapolate to infinity - it’s time to build.

Trading on Base

Visit app.rubicon.finance, connect a wallet, and select the Base network:

Once connected, you can start trading on Rubicon! Swap finds the best route to swap two tokens on the Rubicon order books, while Trade provides a traditional order book UI for trading ERC-20 token pairs with onchain Limit and Market orders:

Sending tokens to Base

If you need to send ETH or ERC-20 tokens to Base, you can use the Bridge in the Rubicon App to find the best route to bridge to Base from 12 other chains:

Rubicon Overview

Rubicon is an onchain order book protocol built on the leading Ethereum L2 networks.

On Rubicon, Limit Orders earn fees. When an order is filled, the majority of protocol fees are paid directly to the “maker”, the address that placed the order, as a rebate. Maker Rebates compensate traders that provide liquidity on the protocol, helping them cover their transaction fees and the risk of providing liquidity onchain.

Paying gas fees for every single limit/cancel order can get expensive. To solve this, Rubicon has Batch Orders, novel order types traders use to place, cancel, or update hundreds of orders in a single transaction, limited only by the network’s block/transaction gas limit. By batching many orders into one transaction, traders can prorate transaction fees across multiple orders, reducing their cost per order.

By saving on transaction fees with rebates and batch orders, Rubicon market makers can actively update their onchain positions as prices change on centralized exchanges. This means better returns for liquidity providers, and lower spreads/better rates for traders!

Rubicon has landed on @arbitrum!

Start trading with Swaps, Limit Orders, and Market Orders on the largest Ethereum L2 network

Rubicon Overview

Rubicon is an on-chain order book protocol built on the leading Ethereum L2 networks. The core order book contract supports peer-to-peer trading for any ERC-20/ERC-20 token pairs!

On Rubicon, Limit Orders earn fees. When an order is filled, 95% of trading fees are paid directly to the “maker”, the address that placed the order. Maker Rebates compensate traders that provide liquidity on the protocol, helping them cover their transaction fees.

Paying gas fees for every update to the order book can get expensive. Rubicon also introduces Batch Orders, novel order types traders can use to place, cancel, or update hundreds of orders in a single transaction, limited only by the network’s block/transaction gas limit. By batching many orders into one transaction, traders can prorate transaction fees across multiple orders, reducing their cost per order.

By earning rebates and using efficient batch orders, market makers can place low spreads on Rubicon, meaning traders get the best rate on the network! We like to call this Network Best Bid Offer (NBBO), and we’re excited to bring it to Arbitrum and more L2s soon!

In this post, we’ll show you how to get started with the SDK, and walk through an example of placing a Limit Order on WETH/USDC while logging relevant data!

• SDK Github Repo

• SDK Docs

Overview

Most DeFi SDKs and tooling are built in JavaScript/TypeScript and aimed at a crypto-native user base. We talked to lots of user groups and recognized the need for a different form of programmatic interface that would allow developers of all levels to get started using the Rubicon protocol. It quickly became clear that Python is widely used in the world of crypto trading for everything from trading systems to data analysis, but is not well supported throughout DeFi.

The result is rubi-py: an SDK that offers developers a wide range of functionality for interacting with the Rubicon smart contracts within their Python applications. With a focus on efficiency and reliability, rubi-py offers seamless integration with the protocol without needing to learn a new language or navigate complex tooling.

Getting Started

To get started, install the rubi package using pip or poetry. We recommend using poetry, as it handles the virtual environment and dependencies while offering easy testing commands.

The main entry point is the client class. It provides a simple and understandable interface for interacting with the Rubicon protocol.

To instantiate a read-write client, create a .env file with the following format:

HTTP_NODE_URL = <an optimism mainnet node url>
WALLET = <wallet address that will sign transactions and pay gas>
KEY = <private key of the signing address>

Optimism provides a public endpoint with rate limits, and you can also get a node URL from a provider like Alchemy or Infura.

To read the environment variables, you can use the python-dotenv package as follows:

import os
from dotenv import load_dotenv

# load from env file
load_dotenv(".env")

# set the env variables
http_node_url = os.getenv("HTTP_NODE_URL")
wallet = os.getenv("WALLET")
key = os.getenv("KEY")

Finally, we instantiate a client to start interacting with Rubicon:

import os
from dotenv import load_dotenv
from rubi import Client

# load from env file
load_dotenv(".env")

# set the env variables
http_node_url = os.getenv("HTTP_NODE_URL")
wallet = os.getenv("WALLET")
key = os.getenv("KEY")

# create a read-write client
client = Client.from_http_node_url(
    http_node_url=http_node_url,
    wallet=wallet,
    key=key
)

Example: Placing a Limit Order

Here’s a full example that instantiates a client, places a new LimitOrder on the WETH/USDC pair on the Rubicon order book contract, and logs the market activity of the pair:

import logging as log
import os
from _decimal import Decimal
from multiprocessing import Queue

from dotenv import load_dotenv

from rubi import Client
from rubi import EmitOfferEvent, Transaction, NewLimitOrder, OrderSide

# load from env file
load_dotenv(".env")

# set logging to get events emitted by the contract
log.basicConfig(level=log.INFO)

# set the env variables
http_node_url = os.getenv("HTTP_NODE_URL")
wallet = os.getenv("DEV_WALLET")
key = os.getenv("DEV_KEY")

# create a queue to receive messages
queue = Queue()

# create client
client = Client.from_http_node_url(
    http_node_url=http_node_url,
    wallet=wallet,
    key=key,
    message_queue=queue
)

# add the WETH/USDC pair to the client and set token allowances (optional)
client.add_pair(pair_name="WETH/USDC", base_asset_allowance=Decimal("1"), quote_asset_allowance=Decimal("2000"))

# start listening to offer events created by your wallet on the WETH/USDC market 
# and the WETH/USDC order book
client.start_event_poller("WETH/USDC", event_type=EmitOfferEvent)
client.start_orderbook_poller("WETH/USDC")

# create a new limit order
limit_order = NewLimitOrder(
    pair_name="WETH/USDC",
    order_side=OrderSide.BUY,
    size=Decimal("1"),
    price=Decimal("1914.13")
)

# place the limit order transaction
transaction_result = client.place_limit_order(
    transaction=Transaction(
        orders=[limit_order]
    )
)
log.info(transaction_result)

# print events and order books
while True:
    message = queue.get()
    log.info(message)

To understand more about event polling and the queue, visit the SDK docs.

Diving Deeper: Batch Order Functions

We hope this intro to rubi-py helps you get started interacting with the Rubicon protocol using Python!

For traders who want to use the SDK in production systems and reduce their gas costs, we recommend checking out the batch order functions that enable you to place, cancel, or update multiple orders in a single transaction, limited only by the networks gas limit!

Contributing

This SDK is open-source under the Apache 2.0 license, and all contributions and feedback are welcome! You can open an issue or request a new feature on Github. We are excited to continue improving rubi-py, and feature requests with widespread community support will be prioritized!

Lastly, many thanks to the core contributors Adam, Denver, and Ishan for their work building and maintaining this SDK!

Program Details

In total, 80,000 OP will be rewarded to liquidity providers on Rubicon over 3 months.

Every 4 weeks, 26,667 OP will be airdropped to addresses, proportional to their maker volume in the previous epoch. The program will run for an initial 3-month period, with an option to be renewed for two more months if it hits certain benchmarks.

Volume on the following token pairs will be counted for the Maker Program:

WETH/USDC, WETH/DAI, WETH/USDT, OP/USDC, USDC/DAI

How is Maker Volume Calculated?

The RubiconV2_Optimism subgraph will be the source of truth for trading volumes throughout the contest.

Whether you are submitting limit orders through the Rubicon App or placing offers through an automated trading bot, all maker volume will earn rewards! 🥳

Program Objective

The rewards program was initially outlined in Rubicon’s grant proposal on the Optimism Governance forum, with the goal of incentivizing active market makers and liquidity providers, who are essential power users of the protocol. On average, maker addresses place more than 1000 offers, and adjusting for addresses with more than 100 offers, the average jumps to more than 37,000 offers!

Volume Leaderboard

A great place to track Volumes is the Leaderboard in the Rubicon App 📈

Prepare to Earn Rewards!

Visit the docs to learn more about how to start Market Making on Rubicon!

Our team built open-source market-making bots, a Python SDK, and many other tools to help you start trading on the protocol. 🤝

If you have any questions or need help while onboarding, send a message in the Discord server or send a note to integrations@rubicon.finance.

New versions of the order book and router smart contracts are live on the following test networks: Arbitrum Goerli, Optimism Goerli, Polygon Mumbai

Traders can start using the new contracts by switching to testnets in the app, and Developers can start building and testing on the V2 contracts in testnet sandboxes!

Keep reading to get the scoop on V2, and subscribe to get Rubicon updates in your inbox!

What’s New in V2?

This upgrade reworks trading fees on Rubicon and adds new, gas-efficient order types to the order book contract. Both changes improve the core economics of the protocol and are aimed at making Rubicon the most efficient place to trade on every Ethereum L2 network.

Fee Updates

In Rubicon V1, every trade that ‘takes’ liquidity from the order book pays a 0.01% fee.

In V2, the majority of this fee is now paid to the address that placed the order and “made” liquidity on the book.

In other words, if your limit order is filled, you will earn an additional fee! These rebates will improve returns for liquidity providers and help traders recover some of the fees spent on gas.

Batch Orders

V2 adds new and more efficient order types called Batch Orders. These orders allow traders to make multiple (20+) limit orders and cancel orders in a single transaction!

Using Batch Orders, automated traders and market makers can save on gas fees by prorating costs across multiple orders. For example, placing one limit order today may cost $0.10 in gas fees, but placing 25 orders at once may cost ~$0.30, depending on network conditions on Ethereum and the L2 network.

Traders can access Batch Orders in two places. They can use them at the low-level on RubiconMarket.sol through the batchOffer(), batchCancel(), and batchRequote() functions, or they can deploy a MarketAid.sol helper contract and access custom trading functions.

We’re excited to see traders experiment with and build on these new order types!

The good news is that deprecating these liquidity pools is one of the first steps in our transition to Rubicon V2! Look out for more news in the coming days and weeks on our media channels regarding the next version of Rubicon 👀

Background

Rubicon Pools was a novel liquidity mechanism that launched on Optimism in September 2021. Passive liquidity providers (LPs) could deposit tokens into single asset pools where active liquidity managers (strategists) used the tokens to provide liquidity by market-marking on the Rubicon order books. Returns from market-making were passed on to the LPs while strategists earned a performance fee.

Pools V1 helped to address Rubicon’s cold-start problem by bootstrapping liquidity on the order books while also giving thousands of users access to market-making returns. The liquidity pools peaked last month at more $15 million in Total Value Locked (TVL) and are responsible for providing liquidity or ‘making’ for more than $30 million in trading volume.

While Pools V1 was live, one thing became apparent to both our community and our team: passive liquidity is a myth. Passive players in an active marketplace expose themselves to lots of toxic flow and will have negative returns. In a sense, the only true form of “passive” liquidity is lending.

While the intentions of Pools V1 were noble: democratize liquidity-providing through a system that has clear roles and balanced incentives for passive suppliers and active managers; the implementation left much to be desired with users exposed to directional risks, trust compromises within the strategist setup, and some liveness issues.

Last year, our team set out to reshape the relationship between the Rubicon order book protocol and the liquidity pools. This new system needed to be capital efficient, trustless, and secure…

Looking Forward

Over the past few months we have been heads down building the next generation of the Rubicon protocol. Rubicon V2 combines two powerful DeFi primitives to form an efficient and secure foundation for Rubicon to become the world order book. We’re excited to share more soon, keep a look out on our social platforms!

With the new interface, traders can place Limit Orders and Market Orders while tracking markets with live price charts and order books!

Trade Overview

First, select a trading pair. The Rubicon protocol is permissionless and supports trading of any ERC-20 token, but for now, the App uses a shortlist of popular tokens on Optimism. Select or flip the tokens to view the chart and order book for the pair:

Now it’s time to place a trade. Market Orders specify a quantity and are executed instantly at the market price, the best possible price on the order book. These orders pay a 0.01% protocol fee for “taking” liquidity off the book. Swaps on Rubicon are effectively market orders that can route across multiple order books!

Limit Orders specify a price and a quantity and are only filled if the market price crosses the limit price. Note that tokens offered in a limit order are sent to the Rubicon order book contract and remain there until the order is filled or canceled. Traders can cancel orders and check their status under the Orders tab or the History page:

To learn more about the Rubicon protocol at a technical level, visit our documentation. There you can find overviews of the smart contracts (e.g. RubiconMarket) as well as helpful tools for developers like our Python and Rust SDKs. If you need help onboarding a trading bot, ask questions in our Discord!

Live Charts & Market Data

Regardless of what they trade, people love the feature-rich charts from TradingView. Rubicon integrated the Technical Analysis Charts, which have many chart types, dozens of technical analysis (TA) tools, custom time/date ranges, and seamless price scaling. Our team really likes Fullscreen Mode:

The data that populates the charts, the order books, and open orders is queried from Rubicon’s subgraphs; open APIs for querying historical data from the blockchain. You can use our subgraphs to query market data and historical token prices. Here are links to getting started:

Learn About Rubicon

Rubicon is an order book protocol for Ethereum, built on Optimism. You can use it to swap tokens, trade with Limit Orders and Market Orders, or earn by providing liquidity to market makers. Answers for the Rubicon Quest Quiz can be found below!

Rubicon uses order books (a list of buy and sell orders for an asset organized by price level) to match traders. Rubicon order books are fully on-chain within the RubiconMarket smart contract, there are no off-chain servers or points of failure! For token swaps, our router contract finds the best price for the swap across the Rubicon order books.

When a trader submits a limit order on Rubicon, it sits on the order book contract and will automatically fill if the market price crosses the limit price, there is no maintenance or keeper bot required! Limit orders can be canceled on the Trade page under Open Orders or by interacting with the contract directly and calling cancel().

Since Rubicon order books are on-chain, all trades require gas fees that are paid in ETH. To save on gas fees, market makers can batch Rubicon orders together in a single transaction. In this example, a market maker on the OP/USDC pair cancels 10 outstanding orders and replaces them with 10 new orders in a single transaction, paying only $0.07 in gas! 🤯

Rubicon also has liquidity pools where users can supply liquidity to earn a share of market-making yield and as well as OP rewards. When a liquidity provider (LP) deposits tokens into a pool, they receive bathTokens, which represent their share of the underlying pool. Ex. LP deposits USDC and receives bathUSDC.

Claiming for the OP airdrop will close in 4.2 months around the end of the calendar year. After this, any remaining unclaimed OP will be sent to the bathOP pool.

Background

In Rubicon’s proposal on the Optimism governance forum, we announced that part of our allocation would go towards a 135,000 OP airdrop to early users. In that post, we outlined how the majority of the drop would go to liquidity providers with a smaller portion going to traders, and both categories would receive a bonus multiplier if they used the protocol before the OVM 2.0 upgrade. You can review the code that determined our airdrop distribution here, and if you want to provide feedback on our methodology let us know in the #suggestions channel in our Discord!

On November 11th, 2021, the Optimism network went through a regenesis for an upgrade that implemented EVM equivalence and marked the end of OVM 1.0. Because of this interruption, we needed to utilize Dune, our own snapshots, and Optimistic Etherscan to collect and verify Rubicon data from OVM 1.0. The process of retrieving data after the network upgrade was much easier, all trading and liquidity pool data can be queried from the Rubicon subgraphs.

Rubicon traders and liquidity providers prior to the release of our Optimism governance proposal, on Monday, May 23rd, 2022 at 21:06 GMT were eligible for the airdrop. The cutoff for the OVM 1.0 multipliers was Friday, November 12th, 2021 at 06:00 GMT. Here is an overview of how the OP airdrop amounts were determined:

Traders

Determining OP distributions for Rubicon traders was straightforward. We calculated the volume for every unique address that interacted with the protocol and applied a minimum volume cutoff to filter out Sybil attackers. As outlined in the proposal, users that traded on Rubicon before the OVM 2.0 upgrade received a 1.5x multiplier on their airdrop.

One of the great things about layer 2 (L2) networks like Optimism is that the low fees make apps like Rubicon accessible to a large population of users who cannot afford to use DeFi on the Ethereum base layer. It was important to us to avoid choosing a volume cutoff that was too high and could exclude a lot of genuine Rubicon users. After filtering through the protocol’s trading history, we determined that $10 of volume was a balanced cutoff that filtered out thousand of clear Sybil attackers while including lots of users who simply have smaller wallets. The cutoff may seem small, but many Rubicon trades are for small amounts with the average trade being less than $100:

Liquidity Providers

The majority of this airdrop went to Rubicon liquidity providers (LPs), specifically those that lost funds in the vampire attack last year.

Our methodology rewarded liquidity providers for both their relative share of liquidity and the duration for which they supplied liquidity. Users who provided liquidity before the OVM 2.0 upgrade received a 2.25x multiplier on this airdrop. In total, 83% of this drop went to those who used Rubicon before the OVM 2.0 upgrade. The bathETH and bathUSDC pools experienced most of the losses in the attack, so those liquidity providers to those pools received preference in the airdrop.

The final amount of OP a liquidity provider received was calculated using their relative share of a pool and the duration of time they supplied liquidity to the pool. We measured each address’s relative proportion of a pool over time and then calculated the total duration each address maintained a pool position.

We multiplied the duration of time an address supplied liquidity to the pool and the proportion of the liquidity pool they supplied and divided it by the lifetime of the pool to give us an address’s capital-weighted and time-weighted pool exposure. Here’s the formula:

Did our team get this drop?

Recently there was a controversy in Optimism governance when the team that received the largest OP allocation chose to gift themselves more than 70% of an airdrop intended for their users.

Even before this event happened, we chose to exclude any Rubicon team addresses that interacted with the protocol. This airdrop is for you, not us.

Thank You!

If you received this OP airdrop, thanks for being part of Rubicon’s journey thus far. We have a long way to go (and a lot more to build!) to fulfill our vision for order books on Ethereum and are thankful for each and every 0x that used the protocol.

From all of us at Rubicon, thank you. ❤️

Powered by Socket, our Bridge finds the best route from major token bridges with support for hundreds of token combinations and 9 blockchains:

Whether you are bridging to Optimism to trade on Rubicon for the first time or you’re seizing an opportunity on another chain, our Bridge finds you the best route without having to leave the App!

After launching the Bridge, select which blockchains you are sending From and To and which tokens you want to send and receive. Socket’s API does all the work, finding the best route for any token combination:

The Bridge defaults to the route that gets you the most tokens possible on the destination chain, but you can also choose a route with cheaper fees. Remember that if it’s your first time on a new chain, you need the native token to pay network fees (gas). On Optimism, gas fees are paid in ETH.

There is a complete guide to using the Bridge in the Rubicon docs ⬅️

Superior Bridging Experience

Most DeFi apps send users to a third-party website to bridge tokens between blockchains. This process is confusing, time-consuming, and unfortunately, sometimes dangerous. More than $1 billion of user funds were lost in bridge hacks in the past year.

With this bridge integration, Rubicon traders can seamlessly transfer crypto assets across chains without having to leave the app!

Our team also takes security very seriously and wants to ensure that we only direct users to bridges with robust security models and reliable liquidity. We do an internal security review before adding a new bridge to the integration, and when possible we inform our decision with L2Beat’s proposed bridge framework.

Integrating with Socket

After exploring many bridging solutions, we believe Socket gives users the best possible experience.

Socket powers truly multichain apps, acting as a meta-layer that gives protocols like Rubicon seamless connectivity across chains and enables developers to build unified apps with shared liquidity & state across chains. In other words, this bridge is just one way Rubicon can use Socket’s powerful interoperability stack.

You may also recognize them as the team behind Bungee, one of the fastest-growing apps in DeFi, which is also built on their Socket API.

Happy bridging anon! 🌉

To get involved, join the Rubicon Discord and visit the #contributing channel. If you have a project in mind, you can apply for a grant by submitting the Application Form.

Grants Program Details

Our Grants program is continuous; contributors can apply for funding at any time!

Once an application is submitted, our team will share feedback and suggestions during a two-week Review Period. At the end of the Review Period, a grant will either be accepted or rejected. Do not worry if your application is rejected, you can always apply again.

We evaluate every grant application on a case-by-case basis. Here are some guidelines for prospective Rubicon grantees when planning their projects:

• Measure Impact

• Be Specific

• Improve Accessibility

Inspired by retroactive public goods funding (RPGF), our program will also issue retroactive grants! This will start as retroactive grants issued on a subjective basis by our team to contributors who made an impact but never applied for funding. Over time, it will transition to a community-led process where discussions, polls, and other coordination tools determine retroactive grant recipients.

If you plan on contributing code or building a project on top of Rubicon, it must be on Optimism in order to receive an OP grant.

First Grant Recipients

To start the Rubicon Grants Program off right, we are issuing three retroactive grants to awesome contributors who made an impact without the expectation of funding:

1. A few months ago, Discord user destiny translated the Rubicon Docs for our Chinese community (and wants to continue translating more resources!) 🇨🇳

2. User Experience Research (UXR) consultants from the University of Southern California’s Masters in Applied Psychology Program did Usability Testing on the Rubicon App that produced great insights for improving our interface and DeFi interfaces in general 💻

3. So far Discord user Axiomatix has produced the highest quality Rubicon memes 🤝

Credit where Credit is Due

The Rubicon Grants Program is only possible because of the Optimism Foundation. As part of their distribution to early projects, Rubicon received a token allocation that passed through an Optimism Governance vote. It’s rare for a DeFi protocol at our stage to be able to reward contributors with grants, and for that we are thankful. 🙏

All grants are issued in the OP token with the target of distributing 135,000 OP (currently ~$98,000) in grants over the next 6 months!

Starting today, Rubicon liquidity providers will start receiving OP rewards! You can now view these rewards on the Pools page in the Rubicon App. It’s time to kick off OP summer with a pool party! 🏊

Last fall, Rubicon was one of the first apps to launch on the Optimism layer 2 (L2) network. As a part of Optimism’s Phase 0 Distribution to early projects, Rubicon received an OP token allocation to bring more liquidity and users to the network! 📈

Liquidity Rewards

In total 540,000 OP will be distributed to Rubicon liquidity providers over a period of 6.9 months (209.875 days). This makes our liquidity rewards program one of the largest on Optimism!

Historical Rubicon trading volumes and Total Value Locked (TVL) helped determine the reward amounts for each liquidity pool:

Liquidity providers (LPs) will receive OP rewards proportional to their share of the pool. The Pools page was updated to include a Rewards rate derived from the current price of OP and the rate of rewards:

These OP rewards are separate from and in addition to the standard market-making yields in Rubicon Pools. We hope you enjoy the rewards! 🥳

Rubicon LPs can claim their rewards by selecting a pool and then pressing ‘Claim’:

Where is the rest of the OP Allocation going?

You can read the exact plan in our Phase 0 proposal that recently passed through Optimism governance. Thank you to all of the OP holders who voted!

In short, liquidity rewards are not the only use of this allocation, we also have a Rubicon Grants Program and an Airdrop to early users coming soon so stay tuned for updates on both of those!

And as outlined in the proposal, 90,000 OP was deposited into our OP pool to bootstrap more liquidity for Optimism’s native token on the Rubicon order books.

As of writing, the Rubicon order books have tighter spreads than ever before, all Pools have produced positive monthly returns, and OP liquidity mining on Rubicon is right around the corner! A few other highlights include OP markets going live, the protocol reaching $1 million total value locked (TVL), and our Code4rena audit contest for the Rubicon v1 codebase.

This month we will officially launch Rubicon v1 on Optimism once we release a protocol version that implements recommendations from the audit contest!

Launching OP Support

On May 31st, Optimism airdropped the OP token to more than 130,000 addresses! Most Rubicon users were able to claim this airdrop, if you have not already claimed you can check your eligibility here.

Shortly after the drop, Rubicon order books went live for OP-USDC, which has been the most popular pair on Rubicon since its launch 🔥

In its first full week of trading, the OP liquidity pool produced over 4% returns for liquidity providers. That’s the power of active management!

It’s important to remember that liquidity pools on Rubicon can have negative returns depending on market conditions, but so far we are very excited about the OP pool’s performance!

Rubicon’s OP Proposal

As part of the launch of Optimism governance, the Optimism team proposed OP allocations to projects built on the network. Rubicon received an allocation of 900,000 OP, which we will use to incentivize liquidity providers, reward early users with an airdrop, start a Rubicon Grants Program, and seed the OP liquidity pool.

You can find more details in our proposal on the Optimism governance forum, but here’s the summary:

• 540,000 to OP Liquidity Mining in Rubicon Pools

• 135,000 to a Rubicon Grants Program

• 135,000 to an Early User Airdrop

• 90,000 to the OP liquidity pool

The Phase 0 proposals from Optimism projects will go through Optimism governance in one batch, with voting starting June 9th. If you are an OP holder, you can vote on the proposal through Snapshot. A vote for this proposal would kickstart OP liquidity mining on Rubicon and over a dozen other apps on Optimism! So far, it looks like the proposal will pass 🥳

Code4rena Audit Contest

On May 23rd, Rubicon started a $50k audit contest on Code4rena covering the Rubicon v1 codebase.

The contest was a massive success, we got great feedback on our contracts from dozens of C4 wardens, and have already started implementing their recommendations.

In the coming weeks, Code4rena will publish a report on the Rubicon contest. In addition to this, we plan to publish our own writeup that will detail protocol changes to be implemented in a v1.3 protocol release.

New Open Orders UI

After receiving feedback from our community, we made some improvements to the Open Order tab to increase its usability and convey more information to traders:

What’s Next

This month we plan to officially release Rubicon v1, continue adding support for new markets, improving the Rubicon app, and refining Rubicon Pools to prepare for the decentralization of market making.

And on top of all these upgrades, Rubicon will receive an OP allocation this month! This means OP liquidity mining, an OP airdrop to early users, and the start of a grants program for contributors 😎

This is not a bug bounty - the contest has guaranteed payouts for all legit findings, so go tell your neighborhood security researcher about it! 🕵️🔎

Here are our Contest Details:

• 47,500 USDC main rewards pool

• 2,500 USDC gas optimization rewards pool

• Starts May 23, 2022 20:00 UTC

• Ends May 28, 2022 19:59 UTC

• To participate, sign up to be a Warden and join the C4 Discord!

Visit Rubicon’s contest page on Code4rena for more details, an overview of our contracts, or to report a finding! After the contest is over, Code4rena will publish a report (like these) summarizing the findings, and we plan to publish one as well.

Security is incredibly important to us, not just within the protocol, but throughout the Rubicon tech stack. We chose to hold a Code4rena contest for Rubicon v1 because we believe they have several advantages over alternative security options. Unlike bug bounties, Code4rena contests have guaranteed payouts for auditors and make more sense for fresh code. Compared to traditional audits, Code4rena contests are much more flexible and anyone can be a part of them! This means more feedback from a diverse set of security researchers.

To get started with the Rubicon Subgraphs, visit our API documentation to see an outline of their functionality as well as some example queries. You can also interact with the Rubicon subgraphs on the Graph Playground. (RubiconMarket, BathToken)

Read on to learn more about current uses for the Rubicon v1 Subgraphs and useful tips for getting started with our APIs.

Building on The Graph

Our team is committed to minimizing dependencies and single points of failure throughout the Rubicon tech stack. The launch of Rubicon Subgraphs marks an important step in our mission to provide a robust decentralized application. In the future, we are excited to grow alongside The Graph and migrate from their Hosted Service to their Decentralized Network as soon as Layer 2 networks are supported. For more details on this, check out The Graph’s Roadmap!

Our goal with this upgrade is to provide direct and easy access to data to support all Rubicon users. From an application standpoint, we are pleased to say that the web experience you now see when you navigate to app.rubicon.finance is powered by The Graph and your wallet’s web3 connection!

Rubicon Subgraphs

For a more detailed explanation of the Rubicon Subgraphs, visit our API docs. You can also read the code in the Rubicon subgraphs repo on GitHub.

At a high level, the Rubicon Subgraphs watch the Rubicon smart contracts and update values in their databases based upon a predefined set of rules when someone uses the protocol. For example, when a user places a trade, it is recorded in a subgraph, which is queried to populate their History page, Open Orders, and other features on the Rubicon web app.

Rubicon v1 has two primary subgraphs:

• RubiconMarket: Tracks all trading activity (maker & taker trades) on the Rubicon order books. Also acts as a reference for an asset’s price history on Rubicon

• BathToken: Tracks all activity (deposits, withdrawals, & earnings) on the Rubicon liquidity pools. Also serves as a reference for the historical performance of the liquidity pools

Say hello to the World Order Book’s first APIs 🌎📖

Exploring Rubicon Data

Want to start exploring Rubicon data? You can use The Graph’s Playground tool to query data without even calling an API! Here are some example queries we think you will find useful:

• A query to get the current offers on the Rubicon Order Books

• A query to check the current status of Rubicon’s Liquidity Pools

• A query to return all trades that have happened on the Rubicon protocol

Stay tuned for more on this front! We are always working to build out more open source Rubicon tooling and are excited to share more 🔜!

What’s Next?

All historical Rubicon data is on-chain, so our task is to illuminate the dark forest so our team and community can use this data to inform future decisions. Here’s what’s next in Rubicon data:

• Rubicon v1 Dune dashboards are live, more on composable components 🔜

• A comprehensive Rubicon metrics and analytics page is in the works 👀

• More data feeds and tooling for market making and trading, if there is a feature you want to see in our Trading SDK let us know in Discord!

Our Head of Growth Denver built the Rubicon v1 subgraphs and continues to lead their development. He has exciting plans to continue using subgraphs for Rubicon’s critical data infrastructure. We will deploy subgraphs along with the Rubicon v1 contracts whenever we launch on new L2 networks, you can visit our docs for a list of active subgraph deployments.

About The Graph

In the past, indexing blockchain data was fairly difficult and time-consuming. Blockchain properties like finality, chain reorganizations, or uncled blocks complicated this data collection process, making it not just time-consuming, but conceptually hard to retrieve correct query results from blockchain data.

The Graph solved this indexing issue through a decentralized protocol that indexes and enables the performant and efficient querying of blockchain data. These APIs (indexed “subgraphs”) can then be queried with a standard GraphQL API. Today, there is a hosted service as well as a decentralized protocol with the same capabilities. Both are backed by the open-source implementation of Graph Node.

April showers bring May flowers… and the launch of Rubicon v1! That’s right, the next generation of the Rubicon DEX is launching this month on multiple L2 networks. 🥳

To learn what’s new in this protocol upgrade, check out the Rubicon v1 whitepaper. Our March Monthly Update also had some great explanations, and you can get a high-level overview from this tweet thread:

Rubicon

@rubicondefi

Today we are releasing the Rubicon v1 whitepaper

Rubicon v1 is an order book protocol for Ethereum, which we believe is an order book protocol for the world!

Rubicon v1

Rubicon v0 launched on Optimism in late 2021 and saw more than $9.9 million in notional trading volume in just a few months! Armed with months of market data, great feedback from our community, and new all-star team members, our team began work on the future of the Rubicon protocol.

During this development sprint, we made significant improvements to the order book protocol, added awesome new features to the Rubicon App, and revamped our internal trading systems.

Perhaps the biggest protocol change from Rubicon v0 → v1 is external rebalancing for Rubicon Pools.

To recap, liquidity in Rubicon Pools is deployed on the order books by active managers that we call strategists. When a strategist’s order is filled by a trader, the tokens are sent back to the pool as the non-native asset. To realize yield, the pool(s) must rebalance to swap this amount back to the native asset. In v0, Rubicon pools could only rebalance between themselves (the ETH pool could rebalance with the DAI pool):

In v1, pools can now rebalance these outstanding “fill” amounts on other liquidity venues! In other words, the pools can derisk by dumping these excess amounts on AMMs. The target is to always swap internally (because it's cheaper) but having the flexibility to tail off this risk on other venues is proving very important and a great improvement to the Rubicon Pools system:

More rebalancing is great news for LPs who will now realize yield more frequently (less risk exposure), and great news for traders because it should lead to an increase in order book depth!

Our team is excited and ready to launch Rubicon v1 this month! For now, here’s a little teaser of something else that is coming soon:

Make sure to follow us on Twitter and join our Discord to be the first to hear updates!

Rubicon at Devconnect!

In April, some of our team traveled to Amsterdam for Devconnect, one of the biggest Ethereum events of the year!

During this action-packed week, we got to listen to and meet some of the leading developers in the ecosystem. We are working on an in-depth Devconnect Recap post, but here were some of our favorite moments from the week:

At mev.day, we were in the front row as Vitalik explained how MEV affects consensus layer development. He also walked us through his Proposer-Builder Separation (PBS) proposal:

At Layer2Amsterdam, we got to see leading rollup builders from Arbitrum, Optimism, Starkware, and zkSync speak about rollup decentralization. The panel was hosted by Anthony Sassano:

Also at mev.day, Optimism and Arbitrum had back-to-back presentations on their current MEV strategies. These presentations were fascinating; we will have a full breakdown in the upcoming Devconnect Recap post!

Optimism Collective/Allocation

While we were in Amsterdam, we were thrilled to learn that Optimism is launching community governance with the introduction of the Optimism Collective. The OP token will launch later this quarter, if you used Rubicon you may be eligible for the OP Airdrop #1! You can check your eligibility for Airdrop #1 here.

Additionally, Rubicon received a preliminary allocation of OP tokens as part of their Phase 0 Governance Fund. Look out for a proposal on the Optimism governance forum later this week about how we plan to use our OP allocation to reward Rubicon users and stakeholders!
