A high-performance Ethereum Layer 2 built with the OP Stack, Unichain unifies Uniswap-native liquidity for low-cost, fast swaps using ETH gas across the Superchain.
Unichain is an Ethereum-aligned Layer 2 mainnet that uses ETH as its native gas and is EVM compatible, purpose-built to power Uniswap-native DeFi at low cost and high speed. Core use cases include onchain swaps, liquidity provision, strategy vaults, and cross-chain swaps via bridges with fast confirmations. Typical performance: average gas cost often sub-cent to low cents per transfer/swap, ~2s L2 block time, and practical throughput in the hundreds of TPS depending on demand.
Unichain is uniquely Uniswap-focused: it aligns blockspace and tooling around AMM liquidity and execution, enabling DeFi apps to tap native Uniswap liquidity and order flow more directly than on generalized L1s/L2s. It settles to Ethereum, uses ETH for gas, and offers EVM compatibility, giving seconds-level block times and sub-cent to low-cent fees while maintaining Ethereum security. Compared to most L1s (higher fees/latency) and many alt-L2s, this design targets better execution quality and throughput (hundreds of TPS) for swaps and liquidity strategies.
Unichain uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge.
To bridge ETH to Unichain, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Unichain as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Unichain you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Unichain to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send ETH on Unichain, ensure your wallet is connected to the Unichain network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
