A TRC20 address is a unique identifier on the TRON blockchain, always starting with a capital "T" followed by 33 alphanumeric characters — 34 characters in total. For example: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t is the official USDT TRC20 contract address. Understanding the TRC20 address format is essential before sending any USDT or TRX on the TRON network.
TRC20 and ERC20 are the two most commonly used token standards for USDT transfers. TRC20 runs on TRON — it is faster and costs almost nothing in fees. ERC20 runs on Ethereum with higher fees. Always identify your address type before sending: "T..." means TRC20, "0x..." means ERC20.
