What Is TRC-20? The TRON Token Standard Explained
The fungible-token standard behind most of the world’s USDT — how TRC-20 works and why it matters.
Updated June 2026 · TronTokenGenerator
TRC-20 is the technical standard that defines how fungible tokens behave on the TRON blockchain. If you’ve heard of Ethereum’s ERC-20, TRC-20 is its direct equivalent on TRON — a shared set of rules that lets wallets, exchanges and apps support any token without custom integration. It’s the standard behind the majority of the world’s circulating USDT, which lives on TRON precisely because TRC-20 transfers are fast and cheap.
What “fungible” and “standard” mean
Fungible means every unit is identical and interchangeable — one unit of your token is worth exactly the same as any other, just like one pound coin equals another. (Non-fungible tokens, or NFTs, are the opposite: each is unique.)
A standard is a common interface: a list of functions every compliant token must implement. Because every TRC-20 token exposes the same functions, TronLink, Tronscan, SunSwap and exchanges can all support your token the moment it’s deployed — no bespoke work required.
The core TRC-20 functions
Under the hood, a TRC-20 contract implements a familiar set of methods:
totalSupply()— how many tokens exist.balanceOf(address)— the balance of any wallet.transfer(to, amount)— send tokens to another address.approve(spender, amount)andtransferFrom(...)— let a third party (like a DEX) move tokens on your behalf, which is how trading and liquidity pools work.allowance(owner, spender)— check an approved spending limit.
It also defines Transfer and Approval events so wallets and explorers can track activity. You don’t need to understand these to launch — our token creator implements them all correctly for you.
Key token properties you choose
| Property | What it is |
|---|---|
| Name | Full name, e.g. “My Token” |
| Symbol | Ticker, e.g. MYT |
| Decimals | Divisibility — 6 is standard on TRON |
| Total supply | How many tokens exist in total |
For help choosing these, see our token parameters guide and tokenomics guide.
TRC-20 vs other TRON token types
TRON actually has two token standards. TRC-10 is a simpler, native token built into the protocol, while TRC-20 is a smart-contract token with full programmability. Almost every serious project uses TRC-20 because of its flexibility and universal support — we cover the differences in TRC-10 vs TRC-20. If you’re weighing TRON against other chains, see TRC-20 vs ERC-20 and TRC-20 vs BEP-20.
Why build a TRC-20 token?
- Low fees: TRON’s energy and bandwidth model makes transfers extremely cheap.
- Speed: blocks confirm in around three seconds.
- Reach: TRON is one of the most-used networks for stablecoins and retail activity, especially across Asia.
- Support: every major TRON wallet and exchange already speaks TRC-20.
Frequently asked questions
Is USDT on TRON a TRC-20 token?
Yes — USDT-TRON is a TRC-20 token, and it’s the most widely-transferred stablecoin on the network.
Do I need to write a smart contract?
No. Our tool deploys a standard, audited TRC-20 contract for you — you just choose the parameters. Follow our step-by-step guide to creating a TRON token to see the whole process.
Can a TRC-20 token be mintable or burnable?
Yes. These are optional features you can enable at creation — see mintable, burnable & pausable explained.
