Omni Overdrive brings groundbreaking changes, including not just Ethereum Virtual Machine (EVM) functionality but also introducing a major new infrastructure layer that allows for communication between rollups. In essence, Omni Network is now capable of fulfilling its core promise: connecting all rollups to create a seamless development and user experience.

Key Features:

• Broaden Your Horizons: Now, developers are no longer limited to a single rollup. Omni Overdrive enables DApps to function across multiple rollups, starting with Linea, Arbitrum and Scroll.

• Enhanced Liquidity: Say goodbye to fragmented liquidity. DApps can now tap into a larger liquidity network with a more diversified user base across rollups.

Walkthrough

Here's a quick guide on how to get started on Omni Overdrive Testnet:

1. Add Omni Overdrive as a New Network: Follow the guide shared below.

2. Minting OATs: Start by minting your Omni Overdrive Launch Supporter OAT from Galxe.

3. Getting Funds from Faucet: Once you've minted your OAT, you can claim testnet funds from our faucet here. You’ll claim testnet $OMNI, $USDT, $USDC, & $ETH on all integrated rollups from the faucet.

How to Add Omni Overdrive as a New Network

You MUST add Omni Overdrive as a new network in your MetaMask wallet. Our faucet will prompt you to easily add this new network when you're claiming testnet funds. By following these guidelines, you're setting yourself up for a seamless journey on Omni Overdrive!

If you prefer to add the network manually, do not simply edit the old RPC details in your MetaMask to the new Omni Overdrive RPC. This is crucial; otherwise, you'll be tangled in nonce inconsistencies that MetaMask won't easily reconcile. Here is a step-by-step guide to add a custom network to your Metamask wallet.

Below are the network details:

• Network name: Omni Overdrive Testnet

• RPC URL: https://testnet.omni.network/

• Chain ID: 165

• Currency symbol: OMNI

• Block explorer URL: https://testnet.explorer.omni.network

If you still face any issues, here’s how you can rectify it:

1. Select Omni as your network in your Metamask Wallet.

2. Click on the 3 dots on the top right and click “Settings”.

3. Click on “Advance” Settings and then on the “Clear Activity Tab Data” button.

4. Finally, click on “Clear” and you are done.

Final Thoughts

Omni Overdrive Testnet V2 marks a significant milestone for us and the broader blockchain community. We invite you to be an early adopter in this exciting journey. Together, let's set new standards for what's possible in crypto’s future.

About Omni

The Omni Network is a layer 1 blockchain built to connect all rollups. Using Omni, developers can build global applications that are available across all rollups. Secured through restaking $ETH, Omni is a next-generation blockchain leading the frontier in both security and functionality.

Omni is backed by $18M from prominent investors such as Pantera Capital, Two Sigma Ventures and Jump Crypto.

HorizonDEX is driven to deliver an unrivalled trading experience with superior DeFi liquidity efficiency — achieving this via its concentrated liquidity protocol and series of affiliate interoperable functional modules.

HorizonDEX is poised to become a pioneering DeFi project on the revolutionary Layer 2 network, Linea Chain.

Prior to the official launch, we want to ensure everything operates smoothly and users enjoy the best possible experience on our decentralized exchange (DEX). To accomplish this, we will be conducting a testnet period. In this article, we will guide you through the necessary steps to utilize HorizonDEX on the Linea Chain Testnet.

HorizonDEX has an easy-to-navigate website and our Swap tool is highly user-friendly with its basic design. Users can easily swap and exchange their cryptocurrencies on the swap tool.

You need to connect your wallet to the protocol by clicking the Connect Wallet button on the top right side of the screen. HorizonDEX offers its users a rich selection of popular wallets, including Metamask, WalletConnect, Coin98, LEDGER, Brave Wallet, and Coinbase Wallet.

Now you are connected and ready to use the swap. You can select the tokens from the dropdown menu on the right side of the swap box.

HorizonDEX allows you to set your slippage tolerance for the trade, HorizonDEX will offer 0.5 % as default.

Once you submit the order and get approved, the transaction should be confirmed quickly.

Pools section is the place where you can see the full list of the liquidity pools, add liquidity to existing pools and create your own liquidity pool. There are currently ETH/Dai Mock ETH/USDC and ETH/USDT Mock pools. You can swap your Testnet Ethereum to Dai Mock, USDC mock or USDT Mock on the swap tool and then add them into the pools.

You can simply click on the Add Liquidity button on the right side of the pools. Then you will be prompted to select your preferred price range for concentration. We made it easy and provided you with pre-made settings and custom settings.

Active and Passive options are pre-made settings. So users doesn’t have to adjust price range and it will be automatically be adjusted. The difference between Active and Passive options is the yield/risk ratio. Active options offers higher yield and higher risk while Passive offers lower yield and lower risk. If you prefer to make your own setting, you can Select Custom to enter the price range.

Before adding liquidity, firstly you will need to approve the tokens to be spent. If you have ETH and would like to add liquidity to zk.USDT-ETH pair, you will need to wrap it for WETH from Swap page first.

The fee tier defaults at 0.3%. For the testnet we only have 1 fee tiers, but we will have much more for the mainnet.
