USDT on Ethereum and USDT on Tron
It is the same USDT on either side, but not the same object: what you send lives in Ethereum's ledger, and what you receive is issued separately on Tron.
Worth checking before you send: on Ethereum the token is 0xdAC17F958D2ee523a2206206994597C13D831ec7, and the USDT you receive on Tron is TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t.
Ethereum needs 4 confirmations before Cambio releases your USDT; that wait, not the Tron payout, is what you spend time on.
People move a dollar token between chains to reach something only one side has: a protocol, an exchange deposit, or a cheaper onward transfer. Cambio does it as a swap — send USDT on Ethereum, receive USDT on Tron, no account.
