ZkLink ecosystem connects various L1 chains and L2 networks that enables developers and traders to leverage unified liquidity from isolated chains with a secure and seamless user experience, contributing to a more accessible and efficient DeFi ecosystem for everyone.
Zero-knowledge validity proofs are mathematically certified to guarantee only valid transactions are executed and cannot be manipulated or falsified, and hence ensure security of funds.
In virtue of ZK-Rollup's on-chain data availability, account states can always be rolled back in case of attacks, even when all the data on zkLink Layer2 Engine is lost. Zero knowledge guarantees that nobody, including the platform itself, can upload fake zk_proof to the main chain.
A light oracle network independently ensures the consistency of multi-chain states. Such separation of powers in the verification and judgment process ensures no single party controls asset security or is capable of malicious behavior.
The checks and balances design guards zkLink protocol against economic attack from both external hackers and internal stakeholders by assuring that no single branch has too much power.
dApps built on zkLink’s L2 network leverage seamless multi-chain liquidity, with rapid deployment solutions for decentralized and non-custodial order book, AMM, derivatives, and NFT exchanges.
A unified currency for all purposes on the zkLink L2 ecosystem. No need of multiple wallets for separate chains. Minimum friction and finality time.
zkLink is a trading-focus L2 ecosystem that solves liquidity problems, and provides a growing number of chain-agnostic L2 liquidity solutions for dApps developers with various use cases and easy-to-deploy APIs. On the zkLink L2 ecosystem, there will be no boundary between separate chains and segmented local liquidity is aggregated.
atomic swap for order book trades (spot trading and margin trading)
constant product curve and stableswap curve for multi-chain AMMs NFT
mint/trade for multi-chain NFT marketplace.
zkLink supports atomic swap for order book traders (both spot trading and margin trading). With the unified massive liquidity on the zkLink L2 network, we achieve limit orders and stop loss functions in a decentralized way for DeFi traders.
Simple CEX-like user experience
Partial fulfillment and multiple pending orders are supported; Up to 32 maker orders;
Secure and efficient
High performance centralized buy/sell matching, but with decentralized finality; Non-custodial assets, secured by ZK-Rollup L2 wallet;
Easy to deploy for MM
Use existing market making strategy, only an extra sig service is needed.
Permissionlessly create multi-chain LPs that consist of native tokens from separate chains, and of any type, such as ETH-SOL, UNI-CAKE, USD-XXX and more. Multiple trading curves are supported: constant product curve (UNI V2), optimized stableswap curve (Curve.fi), and concentrated liquidity model (UNI V3) - in development.
A Seamless and Easy-to-Use Trading Experience
With negligible slippage on stablecoins.
No need to install multiple wallets from each chain.
Real-time settlement based on zk validity proofs
When traders perceive the "direct" cross-chain liquidity pairs composed of tokens from two separate chains, there is no actual "cross-chain" events happened. As illustrated below, traders only interact with Layer1 smart contracts deployed on both source and target chains, to be more evocative, with a "vault" on each chain containing a single kind of token - where liquidity providers "put" their money.
Step 3 in the figure is elaborated in Multi-chain ZK-Rollup and Multi-chain AMM. In step 2, a Layer1_Watcher on zkLink Layer2 network is constantly monitoring Layer1 smart contract logs, and synchronizes parameters of each transaction to Layer2 engine for computation. Similarly in step 4, a Layer1_Sender passes the verified outcome to Layer1 contract on the according chain, which then transfers the wanted tokens to the trader. This is how zkLink Layer2 contract receives and send information from / to different Layer1 smart contracts.
Supports NFT minting, multi-chain trading, and mapping from any L1 to zkLink L2.
Massive NFT assets from multiple L1 and L2 ecosystems for any audience.
A unified pricing numeraire for NFTs from different blockchains.
Q. What is zkLink?
zkLink is a unified, multi-chain L2 network secured by zero-knowledge technology. We are building multi-chain, multi-purpose DeFi infrastructure for the blockchain industry.
Future use cases built on top of zkLink include:
Multi-chain Order Book trading
Multi-chain AMM trading
NFT marketplace
LaunchPad
L2 Wallet
Derivatives trading
And more… Q. Is zkLink still a cross-chain DEX?# zkLink will not directly offer a decentralized exchange service. Instead, you will see other DeFi projects utilize our technology. We believe zero-knowledge will be a game changer for the multi-chain DeFi-verse and will help deliver a new era of security, speed, and lower cost to the end user.
Q: How will the testnet change?
The testnet is now a suite of demos to showcase use cases built upon our high-level APIs. Anyone is welcome to use our demos, and we are happy to receive feedback and ideas in our Discord community.
Q: What will be the utility of the points (Galaxy NFT points) accrued on the testnet demos?
Since zkLink will now no longer be operating a DEX, the original yield boost will no longer be usable on zkLink directly.
Instead, we plan to work with one of our ecosystem partners for zkLink Loyalty NFT rewards to boost yield farming on their platform.
Either way, we are keeping records of all the points accrued so far, which will be utilized at a later date.
We will also have new incentives for developers to build new features on top of the zkLink L2 network.
Q: Will zkLink have a token sale?
The date and details of a potential token sale and whitelist campaign is yet to be determined.
Keep following our official social media channels - and ignore any rumors of any fake IDO/ICO/private sale notices. Important: We do not yet have a token, so be aware of scams. All announcements will be made to @all at our official Telegram, Discord, and Twitter channels, and we will never contact any community member directly.
Q: Will zkLink airdrop?
There was a one-time, small-scale reward in a previous campaign. We’ve recorded the wallet addresses of winners and we will make good on the promises in the future after the token generation event (TGE).
We cannot commit on a time frame when this allocation will happen, as we are prioritizing the mainnet launch and partnerships.
Q. What is the roadmap of zkLink going forward?
Q1 2022
Launch Multi-Chain order book demo Connect Solana as an EVM-incompatible chain Support Atomic Swap & Optimize Circuit Q2 2022
Connect additional chains Launch Mainnet Q3 2022
Support Decentralized ZK Proofs Integrate oracle on ZK L2 Strengthen atomic swops to support more complex use cases
Q. Has there been a change in the zkLink team? Is zkLink hiring?
The team has not changed and we are in fact expanding! If you are a developer with experience in Solidity, Rust, or ZK-proofs, feel free to speak to us.
Q. Will you continue to maintain the zkLink community now that you are not running a DEX?
Yes! Community is core to everything we do at zkLink. We’ve seen the fast growth of our Telegram, Twitter, Discord, and testnet users, and we would like to thank everyone for their support so far; and hope you’ll continue with us into the future.
Going forward, our community will be more technology focused, and we will have new developer-focused incentives and programs.
Please reach out to us on Discord if you have any questions.
