USDa

USDa is the stablecoin of Avalon Labs, which offers lending and borrowing services to Bitcoin holders. According to Avalon's documentation, USDa is the collateralized debt position (CDP) product of the company's lending platform, which combines centralized and decentralized finance elements (CeDeFi); users can mint USDa against Bitcoin collateral. The ecosystem also has a governance token called AVL.

According to its CoinGecko listing, USDa is available on the Ethereum, Mantle and BNB Chain networks. In CDP models, a stablecoin's dollar peg relies on keeping the collateral value above the debt amount and on positions being liquidated when the collateral ratio falls. Sharp drops in the Bitcoin price, the functioning of the liquidation mechanism and the centralized custody components of the CeDeFi structure are therefore key risk factors.

Because another stablecoin in the catalogue carries the same USDA symbol, the two products are distinguished by identity rather than by symbol. Lzzo.com uses DefiLlama's US dollar reference price linked to the token's CoinGecko identity; when the source returns no current value, no estimated price is shown on the page and the price field stays empty.
