DAI is an Ethereum-based decentralized stablecoin soft-pegged to the U.S. dollar, governed by the Maker Protocol and MakerDAO. Unlike centralized stablecoins backed by fiat reserves, DAI is collateralized by a diverse mix of cryptocurrency assets deposited into smart contract vaults, with new tokens minted only when sufficient collateral is locked. Its core function is to provide a transparent, censorship-resistant dollar-pegged digital currency for DeFi transactions, savings, and cross-border payments.
