TRC-10 vs TRC-20: Understanding TRON’s Two Token Types

TRON has two native token standards, and new creators often ask which to use. TRC-10 is a lightweight token built directly into the TRON protocol; TRC-20 is a smart-contract token, equivalent to Ethereum’s ERC-20. For almost every real project, TRC-20 is the right choice - here’s why.

The core difference

TRC-10 lives at the system level: it’s simple and slightly cheaper to issue, but limited in what it can do. TRC-20 is a full smart contract, so it can include logic like minting, burning, pausing, allowances for DEX trading, and more. That programmability is why TRC-20 is the standard exchanges, wallets and DeFi protocols expect.

Why most projects choose TRC-20

• DeFi compatibility: TRC-20’s approve/transferFrom functions are what let DEXs like SunSwap trade your token. TRC-10 can’t plug into that the same way.
• Features: mintable, burnable and pausable behaviour require contract logic - see the features guide.
• Expectations: when people say “a TRON token,” they almost always mean TRC-20.

A little background

TRC-10 was TRON’s original token mechanism, designed to be lightweight and issued directly by the network rather than by a deployed contract. It’s genuinely efficient for plain issuance, and some early, high-profile tokens started life as TRC-10. But as TRON grew into a hub for DeFi and stablecoins, the limitations became clear: without contract logic, a TRC-10 can’t natively support the approval-based trading that decentralised exchanges rely on. TRC-20, modelled on Ethereum’s ERC-20, filled that gap and quickly became the default for anything that needs to be traded, lent, or integrated.

Cost and complexity

Issuing a TRC-10 has historically carried a fixed network issuance cost, while a TRC-20 is deployed like any smart contract, paying for the deployment in network resources. With a no-code generator the difference is academic - you pay one flat fee and the TRC-20 contract is deployed, verified and handed to you. You get the far more capable standard without taking on any of the technical work.

When might TRC-10 make sense?

TRC-10 can suit an extremely simple use case where you only need to issue and transfer a basic token with no smart-contract features and no DEX listing - for example, an internal points system that never touches a DEX. In practice that’s rare, which is why our token creator deploys TRC-20 tokens. If there’s any chance you’ll want to list on SunSwap, add features, or build community trust through renouncing, choose TRC-20 from the start.

Frequently asked questions

Can I convert a TRC-10 into a TRC-20?

Not directly - they’re different standards. You’d issue a new TRC-20 and migrate holders if needed.

Is TRC-20 harder to create than TRC-10?

Not with a tool. We handle the smart-contract deployment, so creating a TRC-20 is just as easy as filling in a form.

Can a TRC-10 token be listed on SunSwap?

Not in the standard way. SunSwap and other DEXs rely on the approval and transferFrom functions that TRC-20 provides, so a tradable token should be TRC-20. See listing on SunSwap.

Does USDT use TRC-10 or TRC-20?

USDT on TRON is a TRC-20 token. The vast majority of meaningful TRON tokens, including stablecoins, are TRC-20.

If I already have a TRC-10, should I switch?

If you need DEX trading, contract features or broad integration, issuing a TRC-20 and migrating holders is usually worth it. For a token that only ever does basic transfers, TRC-10 may be fine as-is.
