TRC20

TRC20 is a fungible token standard on the Tron blockchain, designed for tokens created and managed by smart contracts. It mirrors the ERC20 standard from Ethereum by providing a common interface for balance tracking, transfers, and approvals, which helps wallets, exchanges, and decentralized applications interact with TRC20 tokens consistently.

A TRC20-compliant token contract typically implements functions such as totalSupply(), balanceOf(address owner), transfer(address to, uint256 value), transferFrom(address from, address to, uint256 value), approve(address spender, uint256 value), and allowance(address owner, address spender). It also emits events such as Transfer and Approval. Tokens include metadata such as name, symbol, and decimals to support user-friendly display.

Deployment and use of TRC20 tokens occur on the Tron Virtual Machine via smart contracts. Once deployed, the contract address identifies the token, and users can manage and transfer tokens using Tron-compatible wallets and supported dApps. TRC20 tokens can participate in DeFi protocols, be listed on Tron-based exchanges, and be integrated into tokenized ecosystems within the Tron network.

Differences from TRC10: TRC20 tokens are programmable and rely on smart contracts, enabling features such as allowances and programmable supply, while TRC10 tokens are simpler, non-programmable tokens issued directly on the Tron blockchain.
