To send USDT from Trust Wallet to Binance, start by opening your Trust Wallet and selecting the USDT token. Click on "Send," then paste your Binance USDT deposit address, ensuring it matches the correct network (e.g., BEP20, ERC20, TRC20) based on Binance’s supported options. Input the amount of USDT you wish to send and confirm the transaction details. Once verified, complete the transaction, and Trust Wallet will process it on the blockchain.
