USDT0 is a cross-chain stablecoin protocol that facilitates the movement of Tether's USD₮ across multiple blockchains using LayerZero's Omnichain Fungible Token (OFT) standard. It employs a lock-and-mint mechanism, locking USD₮ on Ethereum and minting equivalent USDT0 on destination chains, maintaining a 1:1 peg without relying on traditional bridges.
