What's TRC20

TRC20 is not a coin — it’s a a token standard on the TRON blockchain. Think of it as the rulebook: it defines how tokens on the TRON network are created, sent, and received.

You may have seen TRC20 when sending USDT — you’re asked to pick a network. TRC20 is one of those options. When USDT is issued on the TRON network and follows the TRC20 standard, it becomes TRC20 USDT.

What can TRC20 Do？

Using TRC20 for payments

The most common use of TRC20 is transferring USDT. You can send USDT to anyone, anywhere in the world, anytime—no bank account needed. For people living in countries with unstable currencies or limited access to banking, TRC20 USDT is a practical way to store value and move money safely.

  • Cross-border transfers:
    Traditional international transfers are often slow and expensive. With TRC20, you can send Usdt abroad in just a few minutes with very low fees. Whether you’re sending money to family or paying overseas partners, it’s usually faster, cheaper, and more convenient than a bank wire.
  • Deposits and withdrawals on exchanges:
    Most major crypto exchanges support the TRC20 network. When depositing or withdrawing USDT, choosing TRC20 is one of the most popular options because it’s fast and cost-efficient.

TRC20 in the TRON ecosystem

  • DeFi activities:
    TRC20 tokens are widely used in DeFi on the TRON network. You can lend, stake, or provide liquidity to earn rewards and make your crypto work for you.
  • Creating your own token:
    Developers can easily create and launch their own tokens on TRON using the TRC20 standard. These tokens can be used for fundraising, rewarding users, or adding utility to a project.
  • Interacting with smart contracts:
    TRC20 tokens work seamlessly with smart contracts on TRON. This makes them an essential part of many decentralized apps (dApps), from finance platforms to gaming projects.

How Does TRC20 Work?

TRC20 is a smart contract template on the TRON network. Developers follow this template to deploy a smart contract onto the TRON network. The tokens issued and managed by this contract are then called TRC20 tokens.

TRC20 itself is not a specific coin, nor is it a block. It is a set of rules that defines how tokens record total supply, query balances, execute transfers, and handle authorization operations on the TRON network.

Many wallets and exchanges will display “TRC20” or “TRON/TRC20” when users select the network. This is to make it easier for users to choose the correct network. More accurately, TRON is the blockchain network, while TRC20 is the token standard on this network.

How TRC20 Runs on TVM

After a TRC20 contract is deployed on the TRON network, it is executed by TVM.
When a user initiates a TRC20 transfer, the wallet first signs the transaction and then sends it to the TRON network. Once the network receives the transaction, it calls the corresponding TRC20 contract, and the TVM checks whether the operation follows the contract rules, such as whether the balance is sufficient or the authorization is valid.

If all conditions are met, the contract updates the balance records on the blockchain and emits a Transfer event. This allows wallets, block explorers, and exchanges to recognize the TRC20 transfer.

Main Functions in a TRC20 Contract

A standard TRC20 contract usually includes these core functions:

  • totalSupply() — Shows the total number of tokens issued by the contract.
  • balanceOf() — Checks how many tokens a specific address holds.
  • transfer() — Sends tokens directly from the user’s address to another address.
  • approve() — Allows another address, often called a spender, to use a certain amount of tokens.
  • allowance() — Checks how many tokens a spender is allowed to use.
  • transferFrom() — Transfers tokens from one address to another after approval has been granted.

Together, these functions give TRC20 tokens a standard way to work on TRON. They allow wallets, exchanges, and DApps to read balances, process transfers, and manage token approvals in a consistent way.

What Makes TRC20 Popular?

Trc20 Development History

Back in March 2019, Tether announced a partnership with the Tron blockchain and launched USDT based on the TRC20 standard on the Tron network. From then on, TRC20 began to be widely adopted.

  • Problems with ERC20 Usdt ：
    At that time, the stablecoin market relied heavily on Ethereum’s ERC-20 standard. Due to network congestion, users faced high gas fees and slow processing times. During peak periods, transferring $100 of USDT could cost between $10 and $50 in transaction fees, with waiting times stretching from tens of minutes to hours.
  • The TRC20 Solution：
    The launch of TRC-20 USDT successfully solved these problems. By utilizing TRON high-throughput and low-cost infrastructure, it enabled users to complete transfers in just a few seconds at extremely low fees. Following its release, TRC-20 experienced rapid growth and adoption.

Key Features of TRC20

  • Fast Confirmation Speed:
    Tron block time is approximately 3 seconds. Transactions are usually confirmed within a few seconds to 1 minute, making it ideal for high-frequency transfers.
  • Low Transaction Fees:
    Transferring TRC20 USDT typically costs 6.4 to 13.4 TRX. Users can further reduce or even minimize fees by staking TRX or renting Energy. Unlike Ethereum gas fees, TRC20 fees are stable and predictable.
  • High Throughput (TPS):
    The network is designed to handle thousands of transactions per second and rarely experiences congestion.

TRC20 Current Status

  • Market Share:
    As of 2026, TRC20 USDT has long accounted for 45%–50% of the global USDT supply, with a circulation of approximately $89 billion and over 70 million holding accounts.
  • Overtook ERC20 USDT:
    According to DefiLlama stablecoin data, the total circulating stablecoin volume on the Tron network has reached about $89 billion, surpassing Ethereum’s $82.3 billion. This clearly demonstrates that TRC20 has been widely accepted by the market and has become one of the most popular choices for transferring stablecoins globally.

TRC20: The pros

TRC20 has become one of the most practical and efficient token standards on the blockchain, offering excellent benefits for both users and developers. Here are a few to name:

  • High Compatible with ERC20
    TRC20 is compatible with the ERC20 standard, so many developers who have worked with Ethereum can understand and build TRC20 tokens more easily. They can easily move their existing Ethereum smart contracts to Tron with only very small changes. This makes it much faster and cheaper for projects to launch on TRC20.
  • Easy to check on-chain
    TRC20 transfers are recorded on the TRON blockchain, so you can look them up anytime with a Tron block explorer. By checking the transaction hash, users can see where the funds were sent, how much was transferred, and whether the transaction has been confirmed.
  • Stable for Daily transfers
    TRC20 is not only known for its speed, but also for its highly stable transfer experience in daily use. Unlike some networks that often get congested — causing delays and uncertain arrival times — TRC20 rarely fails or gets stuck. This makes it a reliable and trustworthy option for routine crypto transfers.

TRC20:The drawbacks

Despite TRC20’s many advantages, there are, of course, drawbacks. Here are some key concerns about TRC20.

  • Smaller Ecosystem than ERC20
    TRC20 is useful for transfers, especially Usdt transfers, but its ecosystem is not as rich as ERC20 on Ethereum. This makes TRC20 convenient for payments, but less attractive for users looking for more advanced on-chain applications.
  • Decentralized Network, Centralized Tokens
    TRON is a blockchain network, but it still has some centralization concerns. For example, USDT is issued by a centralized company. This means the issuer, like Tether, may be able to freeze or blacklist certain addresses. This means that even though the network is decentralized, users can still have their tokens frozen by the company that issued them.
