Dai on Base (DAI)

Dai (DAI) is a decentralized US-dollar stablecoin on Ethereum, designed to track one US dollar and backed by collateral held in smart contracts rather than by a single issuer. It is a long-standing staple of decentralized payments and DeFi. On Base, DAI moves as a ERC-20 token: transfers pay Base network fees in ETH and settle with the network's own finality. Every U.CASH rail that runs on Base, from checkout to swap, supports DAI natively on this chain.
