USDa wallet

What is USDa (USDA)?

USDa is the dollar stablecoin of Avalon Labs, a Bitcoin-focused lending platform. It is minted in two ways: by depositing USDT one to one, or by opening a collateralized debt position and borrowing USDa against BTC-derived collateral such as wrapped and liquid-staked bitcoin. Either way the token that ends up in your wallet is the same plain ERC-20 style asset pegged to one US dollar. It does not rebase and does not change balance on its own.

Avalon also issues sUSDa, which you receive when you lock USDa in its savings module. That is a separate token with its own contract; a wallet showing zero USDa after you deposited into sUSDa is not a bug, the USDa has simply been exchanged for the staked representation. Redeeming sUSDa turns it back into USDa.

What to check before a transfer

USDa is a multi-chain token bridged between chains through a LayerZero omnichain setup, so the same asset exists as native balances on several networks rather than as a wrapped copy. Every transfer is paid in that chain's own gas coin (ETH, BNB, MNT and so on), never in USDa itself, so you need a little of the gas coin on the same chain.

The ticker is the biggest trap. "USDA" is also the symbol of a completely unrelated dollar stablecoin from Angle Protocol, and both circulate on Ethereum. When adding the token or picking it on an exchange withdrawal page, confirm it is Avalon's USDa and not the Angle one, because the two are not interchangeable.

Supported networks in Tangem (3): Ethereum, BNB Smart Chain, Mantle. Because USDa sits on more than one chain, Tangem keeps a separate balance for each network and shows which network a transaction is going out on before the card signs it, so you check that against what the recipient expects. For a multi-chain stablecoin with a shared ticker, that visibility is exactly what a holder needs, and it is why Tangem works well for keeping USDa.
