Chainlink on Optimism (LINK)

Chainlink (LINK) is the token of the Chainlink decentralized oracle network, which delivers real-world data to smart contracts. LINK pays the node operators who fetch and secure that data, making it one of the most widely held utility tokens. On Optimism, LINK 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 LINK natively on this chain.
