Swapping on and across Unichain

Unichain is a Layer 2 built on Ethereum with a swapping-first purpose, coming from the team most associated with on-chain trading. It's an OP-Stack rollup, so it settles to Ethereum, uses ETH for gas, and keeps the familiar EVM standards and addresses.

Its reason for existing is liquidity and swap efficiency, which makes it a natural fit for the kind of routing an aggregator does. For a user, a Unichain swap feels like an Ethereum swap at a lower fee.

Multiswap compares routes from the engines that quote Unichain and ranks them by net output after estimated gas. Same-chain Unichain swaps and cross-chain routes are compared together.

On a swap-focused L2, comparing across engines is complementary. The network is built for liquidity, and the aggregator finds the best route across what's available for your pair.

Because Unichain uses ETH for gas, you keep a little ETH on the network to transact, with no separate gas token to acquire. That makes arriving on Unichain straightforward for anyone already holding ETH.

Unichain uses standard EVM addresses, so confirm the destination network before sending. As with any L2, the address format alone won't distinguish it from another EVM chain.
