Wanchain Bridged USDC (Cardano) wallet

What is Wanchain Bridged USDC (Cardano) (USDC)?

Dollar tokens do not originate on Cardano, they arrive there. Wanchain's bridge locks USDC on the chain where it was issued and mints a matching Cardano native asset in return, which is the token described here.

So the ticker is honest about what it tracks but not about who stands behind it. This is not Circle's token on Cardano and cannot be redeemed with Circle; converting it back to the original means crossing the bridge again, and its backing rests on the bridge's custody of the locked USDC. Cardano can also carry dollar representations from more than one bridge at a time, all of them showing USDC. What separates them is the policy id, the identifier attached to the asset at minting, and that is the field to compare when something looks ambiguous.

The chain's own accounting matters too. Cardano native assets travel inside UTXOs rather than in a contract's ledger, and every output holding tokens must also carry a minimum amount of ADA with it. In practice you can never hold this token with an empty ADA balance, and transaction fees come out of ADA as well.

That makes keeping ADA and the bridged dollars together a requirement rather than a convenience, and in Tangem they sit in one wallet on one card, so a transfer is composed and signed with a tap against the phone without hunting for fee funds elsewhere. Anything less joined up would just create a stuck balance.
