# USDD > Leading The Financial Future With Stability And Transparency USDD helps crypto users transact with stable value by providing an over-collateralized stablecoin pegged to USD. USDD is a decentralized stablecoin pegged to the US dollar and backed by over-collateralized crypto assets. Users can transact without price volatility, earn savings yield, and use it across DeFi protocols on multiple blockchains. Community governance, on-chain collateral, and a peg stability module for par swaps with other stablecoins support the peg. - Type: Project - Sector: Finance - Status: Active - Founded: 2022-04-01 - Profile: https://thegrid.id/profiles/usdd ## Products - [USDD Stablecoin Protocol](https://thegrid.id/profiles/usdd): USDD Stablecoin Protocol issues USDD against over-collateralized crypto positions held in vaults.
