TRC20 is a technical standard used for smart contracts on the TRON blockchain to implement and govern token issuance and management. Released in 2018, TRC20 defines a set of rules that every token on TRON must follow to be compatible with the broader TRON ecosystem — wallets, exchanges, and decentralized applications (dApps). The TRC20 standard is conceptually similar to Ethereum's ERC20 standard, but it operates on the TRON blockchain using the TRON Virtual Machine (TVM). Developers who know how to build ERC20 tokens on Ethereum can easily adapt their smart contracts for TRC20 on TRON, since the TVM is compatible with Solidity. TRC20 requires tokens to implement a fixed set of functions: totalSupply (returns total token supply), balanceOf (returns balance of an address), transfer (moves tokens), approve (grants spending allowance), allowance (checks allowance), and transferFrom (executes approved transfer). These functions ensure every wallet and exchange knows exactly how to interact with any TRC20 token.
TRC20 is a standard, not a network. It is a set of rules that every token on the TRON blockchain must follow — ensuring compatibility across the entire ecosystem.
Every TRC20 token must implement: totalSupply, balanceOf, transfer, transferFrom, approve, and allowance. These functions ensure all wallets and dApps on TRON can interact with any TRC20 token uniformly, enabling full interoperability across the ecosystem.
