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
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. New to the terminology? Keep our TRON glossary handy as you read.
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.
What TRC-20 tokens are used for
The standard is deliberately general-purpose, which is why it underpins such a wide range of projects on TRON:
- Stablecoins - by far the biggest use. USDT-TRON is a TRC-20, and it settles billions of dollars in transfers every day.
- Utility tokens that grant access to a product, platform or service.
- Community and memecoins - cheap transfers make TRON a popular home for retail-driven tokens. See how to create a memecoin on TRON.
- Reward and loyalty points - low fees make frequent, small distributions affordable.
- Governance tokens that let holders vote on a project’s direction.
TRC-20 and the USDT story
The clearest way to understand TRC-20’s importance is USDT. Tether issues its dollar stablecoin on several chains, but the TRON (TRC-20) version became enormously popular because moving it costs a fraction of a cent and confirms in seconds. That made TRON the rails of choice for remittances and exchange transfers, especially across Asia. When you deploy a TRC-20, you’re using the exact same standard that carries the most-transferred stablecoin in the world - your token speaks the same language as every wallet and exchange that already handles USDT-TRON.
How a TRC-20 token comes to life
Behind the scenes, creating a TRC-20 means writing a contract that implements the standard functions, compiling it for the TRON Virtual Machine (TVM), deploying it on-chain, and verifying the source on Tronscan so holders can trust it. With a no-code generator, all of that happens automatically the moment you pay - you choose the parameters and the contract is deployed, the full supply and ownership sent to your wallet. The end-to-end walkthrough is in how to create a TRON token.
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.
What does TRC stand for?
TRC stands for “TRON Request for Comment,” the naming convention TRON uses for its token standards - mirroring Ethereum’s ERC (“Ethereum Request for Comment”). The 20 is just the standard’s number.
How many decimals should a TRC-20 token have?
Six is the TRON convention (the same as USDT-TRON). Unless you have a specific reason, leave it at 6 - it keeps your token consistent with how holders and DEXs expect amounts to display. More in our parameters guide.
Is a TRC-20 token safe to hold?
The standard itself is battle-tested and used by USDT. Safety comes down to the individual token: whether ownership is renounced, liquidity is locked and the contract is verified. Always check those signals - our security checklist explains how.
