USDD, the algorithmic stablecoin issued by the TRON DAO Reserve, launched its Vault feature on Ethereum on Aug. 24. Users can deposit ETH or WBTC as collateral and mint USDD against part of its value, subject to a minimum collateral ratio of 130%, giving the product a lending-style function. The deployment expands USDD’s Vault infrastructure beyond TRON, where a WBTC Vault launched in April and first enabled Bitcoin-backed USDD minting. The Ethereum rollout establishes a dual-chain Vault structure centered on ETH and BTC, while broadening access for holders of major digital assets to participate in the USDD ecosystem.
