What is Unichain?
Unichain is an EVM-compatible Ethereum layer-2 built by Uniswap Labs on the OP Stack, designed for fast, cheap swaps and DeFi — so MetaMask and ERC-20 tokens work unchanged at very low fees.
Unichain in plain English
Unichain is an Ethereum layer-2 built by the team behind Uniswap, on the same OP Stack as Optimism and Base. It runs standard Ethereum smart contracts with fast, sub-second blocks and low fees, so deploying an ERC-20 token works exactly like Ethereum — only far cheaper.
Gas in ETH
Gas on Unichain is paid in ETH, just like Ethereum and other OP Stack L2s. You need only a small amount of ETH on the Unichain network to transact and deploy a token. Fees are very low.
