# USDT (Tether)

> USD-pegged stablecoin issued by Tether, available on multiple networks in Noxpay.

USDT (USD Tether) is a stablecoin issued by [Tether](https://tether.to/) 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.

## USDT on Noxpay

Noxpay supports USDT on five networks:

| Currency code   | Network           | Notes                                             |
| --------------- | ----------------- | ------------------------------------------------- |
| `USDT_ERC20`    | Ethereum          | ERC-20 token. Uses `0x...` addresses.             |
| `TRX_USDT_S2UZ` | Tron (TRC-20)     | TRC-20 token. Uses `T...` addresses.              |
| `USDT2_AVAX`    | Avalanche C-Chain | Uses `0x...` addresses — same format as Ethereum. |
| `SOL_USDT_EWAY` | Solana            | Uses base58 addresses.                            |
| `USDT_TON`      | TON               | Uses TON-format addresses.                        |

## 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.
