A Tron wallet refuses the 0x… address you pasted for a USDT TRC20 transfer. That is the correct behaviour: the address belongs to a different network family.
Address formats differ by network
According to the Tron account documentation, a Tron address is shown in Base58Check and starts with T; internally it is stored as hex starting with 41. Addresses starting with 0x belong to EVM networks such as Ethereum and BNB Smart Chain.
What to do
- Ask the recipient which network the 0x address is for: ERC20, BEP20 or another EVM chain (see BEP20 vs ERC20 on one address).
- If they need TRC20, ask for their
T…address. - If they need ERC20 or BEP20, move your USDT to that network first.
- Check the address with the address validator and send a small test.
If a multi-chain wallet already sent the transfer on another network, look up the hash in that network's explorer and contact the recipient; whether funds can be found depends on who controls the address, and nobody can promise it in advance.
Do not convert addresses yourself
The same key can derive both formats, but the recipient may not control the Tron version, and exchange deposit addresses differ per network. Always ask for the address together with the network name, and save verified addresses in your address book with a network label. When you need USDT on Tron from another coin, create an order such as TRX to USDT and choose the payout network; the widget validates the address for that network.
FAQ
Can I send USDT TRC20 to a 0x address?
No. Tron expects a T… address. Ask the recipient for a Tron address or switch to the EVM network they use.
What is a Tron address starting with 41?
The internal hex form of a Tron address. Wallets display it as a Base58Check address starting with T.
