What is TRC20
The token standard on the Tron network, the most popular network for USDT transfers thanks to low fees.
USDT TRC20 lives on the Tron blockchain. A transfer takes 1-3 minutes, and the fee is paid in TRX or with the "energy" resource.
Tron addresses start with the letter T. Send USDT TRC20 only to an address that supports this network.
