Introduction to TRC20 and ERC20
TRC20 and ERC20 are two prominent protocols for issuing and managing USDT (Tether), a stablecoin pegged 1:1 to the US dollar. While both serve similar purposes, they operate on different blockchains—TRC20 on Tron and ERC20 on Ethereum—and offer distinct advantages in terms of fees, speed, and functionality.
