USDT0 wallet

What is USDT0 (USDT0)?

Rather than a pile of separate bridge wrappers, USDT0 is Tether's dollar carried between chains by an omnichain token standard: a cross-chain transfer burns the amount on the chain you are leaving and mints the identical amount on the chain you arrive at, with USDT locked on Ethereum standing behind the whole float. The consequence for a holder is that there is no per-chain edition to convert between. The balance is the same unit wherever it turns up.

What still differs from chain to chain is everything around it. The fee for moving it is paid in whatever the local network uses for gas, which is a different coin on each one, so every chain you keep a balance on needs a little of its own gas alongside. And when sending to someone else's deposit address, the receiving side has to be expecting USDT0 on that exact chain: addresses on EVM networks look identical from one chain to the next, and nothing in the string tells you which one it belongs to.

Tangem keeps a separate USDT0 balance per network and names the network a transfer is leaving on in the confirmation the card signs. Matching that to what the recipient expects remains your call; putting it in front of you before the signature is the wallet's part. Supported networks in Tangem (14): Arbitrum One, Optimism, HyperEVM, Hedera Hashgraph, X Layer, Mantle, Polygon POS, Flare Network, Plasma, Monad, Tempo, Rootstock RSK, Sei Network, Ink. With one dollar token spread across this many chains, having the chain spelled out at the moment of signing is what keeps a transfer uneventful.
