USDT (ERC-20) on Ethereum (ERC-20)
USDT on Ethereum is a token, so the transfer is paid in ETH gas, and a token transfer uses more gas than sending plain ETH.
- The wallet you send from needs a little ETH for gas, even though you're sending USDT.
- Send USDT on Ethereum (ERC-20) only. USDT on Tron is the same coin on another network.
- BNB Chain addresses look identical to Ethereum ones. Check the network in your wallet, not just the address.
