Uniswap on Optimism (UNI)

Uniswap (UNI) is the governance token of Uniswap, the widely-used decentralized exchange protocol. UNI holders vote on the protocol's upgrades and treasury, making it one of the best-known DeFi governance tokens. On Optimism, UNI moves as a ERC-20 token: transfers pay Optimism network fees in ETH and settle with the network's own finality. Every U.CASH rail that runs on Optimism, from checkout to swap, supports UNI natively on this chain.
