The token and network are different details
USDT exists on several blockchains. TRC-20 is a token standard on TRON. If the receiving service requests USDT TRC-20, select the TRON network when sending. The USDT name alone is not enough.
Check the address and token
TronLink documentation describes user-facing TRON Base58 addresses as starting with T. Address format alone does not prove that the recipient or token is correct. Compare the network, full address and token contract with official sources. Do not use the token contract address as your personal receiving address.
Using OM USDT
Customers can save their receiving address in USDT Wallets. Entering an address does not require connecting TronLink or sharing wallet keys. The current sandbox is for practice only; do not transfer real assets.
