USDT (USD Tether) is a stablecoin issued by Tether whose value is pegged 1:1 to the US dollar. It is the most widely used stablecoin in the world by trading volume and total supply. Because USDT is a token rather than a native chain asset, it exists as a smart contract on each blockchain it is deployed on. This means the same unit of value — one dollar — is represented by different on-chain tokens depending on the network.

Cross-network risk

Ethereum and Avalanche C-Chain both use 0x... address format. A USDT (ERC-20) address and a USDT (AVAX C-Chain) address look identical at the string level. If you send USDT (ERC-20) to an address that only exists on Avalanche, or vice versa, the withdrawal will be broadcast and confirmed on the source network — but the recipient will not see the funds on their chain. The funds cannot be recovered. Always confirm with your recipient which network they need before selecting a currency code.
