USDa(USDA)

Overview

USDa is a Bitcoin-backed stablecoin issued by Avalon Labs and designed to track the US dollar. Users deposit BTC or related Bitcoin assets as collateral and mint USDa through a collateralized debt position (CDP) model, with the minted USDa burned when the debt is repaid and collateral withdrawn.

Avalon Labs positions itself as a CeDeFi platform for Bitcoin, combining BTC-backed lending, a stablecoin, yield accounts, and a credit card, with USDa as its flagship product. USDa circulates across multiple chains and is used as collateral and liquidity in DeFi protocols; key risk factors commonly cited include Bitcoin collateral volatility, liquidation thresholds, and the mechanisms maintaining the peg.
