USDD, the algorithmic stablecoin backed by Justin Sun, has launched natively on Ethereum after first debuting on Tron in 2022. The rollout includes a Peg Stability Module for minting and swapping with USDT/USDC, plus an airdrop for early adopters and a savings version (sUSDD) offering up to 12% APY. Despite the expansion, rating agency Bluechip still flags USDD’s collateralization and decentralization risks.
