TRC20 is the token standard used on the TRON blockchain for creating and managing fungible tokens. It was developed by the TRON Foundation and is modeled after Ethereum's ERC20 standard, sharing similar core functions but operating on an entirely separate blockchain.
How TRC20 Works
TRC20 tokens are governed by smart contracts deployed on the TRON network. These contracts define token behavior: total supply, transfer rules, balance tracking, and approval mechanisms. The TRON Virtual Machine (TVM) executes these contracts, enabling automatic and trustless token transfers.
TRC20 Address Format
All TRON addresses — including TRC20 token wallets — begin with the letter "T" (for example: T9zP14Xo…). This distinguishes them from Ethereum/ERC20 addresses, which begin with "0x". This difference is critical: sending TRC20 tokens to an "0x" address will result in permanent loss of funds.
Popular TRC20 Tokens
USDT TRC20: By far the most widely used TRC20 token. Tether issues USDT on TRON due to its low transaction costs.
USDC TRC20: USD Coin also exists on TRON.
WIN, BTT: Native TRON ecosystem tokens built on TRC20.
TRC20 vs TRC10
TRC20 is the successor to TRC10, TRON's earlier token standard. TRC10 tokens are issued at the protocol level without smart contracts, making them simpler but less flexible. TRC20 uses smart contracts (via TVM), enabling more complex token logic and DeFi functionality.
Key Advantages of TRC20
Ultra-low transaction fees (under $1), fast confirmation times (3-second blocks), high throughput (100+ TPS), and broad wallet and exchange support make TRC20 one of the most practical standards for everyday stablecoin use.
