What is TRC20? A deep explanation

What is TRC20?

TRC20 is a technical standard for tokens issued on the Tron blockchain. You can think of it as a set of rules that every token on Tron must follow. Thanks to this shared standard, wallets, exchanges, smart contracts and dApps know exactly how to interact with such a token. It is the same idea as ERC-20 on Ethereum, but specifically designed for the Tron network, which is known for its speed and low cost.

When you send USDT (Tether) via the Tron network, you are actually sending a TRC20 token. This standard determines how that token behaves, how it is deposited and transferred, and how smart contracts can communicate with it.

Key Takeaways

• TRC20 is the token standard of the Tron blockchain, comparable to ERC-20 on Ethereum, and ensures uniform rules so wallets, exchanges and smart contracts can work with tokens without issues.
• TRC20 tokens are technically smart contracts with fixed functions such as totalSupply, balanceOf and transfer, running on the fast and low-cost Tron Virtual Machine (TVM).
• The popularity mainly comes from extremely low fees, high speed and broad exchange support, making USDT-TRC20 the dominant global stablecoin transfer route.
• Advantages include low fees, fast transactions, EVM compatibility, widespread stablecoin adoption and energy efficiency, while drawbacks include limited decentralization, dependence on USDT and smart contract risks.
• TRC20 tokens are widely used for payments, stablecoin transfers, DeFi applications and fast exchange transfers, making it one of the most used standards in crypto.

Why does TRC20 exist?

Blockchains cannot just support random tokens. Without fixed rules, every token would work differently, which would create chaos. TRC20 therefore provides:

• Uniformity
  Everyone uses the same basic functions on a blockchain.
• Compatibility
  Wallets and dApps do not have to reinvent how to handle tokens each time.
• Reliability
  Smart contracts know exactly which functions exist and how data is provided.

The goal is simple: a stable and predictable way to create tokens on Tron.

How does a TRC20 token work technically?

To understand how TRC20 works, you have to see it as a smart contract template. Every TRC20 token is essentially a smart contract with a fixed set of functions. These functions determine:

• how many tokens exist (tokenomics)
• how many tokens a wallet owns
• who can send tokens to whom
• how approval is granted to send tokens on someone’s behalf

Step 1. Create a contract following TRC20 rules

The creator of a token writes a smart contract (in a Solidity-like syntax, because Tron's Virtual Machine is heavily based on the EVM).

It defines things such as:

• totalSupply: the total number of tokens
• name and symbol: for example "USDT" or "TRON"
• balanceOf: who owns how many tokens
• transfer: how a wallet sends tokens

If the contract meets the TRC20 standard, it can be accepted by the network.

Step 2. The contract is deployed on the blockchain

Once on Tron, the token is live and wallets and dApps can interact with it. From this moment on, the smart contract does not change, because blockchain code is permanent. You cannot modify the rules after launch, which is also reassuring when using DeFi applications.

Step 3. Wallets and apps recognize it automatically

Because TRC20 is a uniform protocol, all Tron-compatible services know exactly:

• how to read balances
• how to send transactions
• how to execute contract interactions

This is why a token like USDT on Tron works as seamlessly in your wallet as TRX itself.

The role of the Tron Virtual Machine (TVM)

TRC20 runs on top of the TVM (the Tron Virtual Machine). This is the runtime environment that executes smart contracts, almost identical to Ethereum’s Virtual Machine (EVM). As a result, it is:

• extremely fast
• efficient
• inexpensive

Each transaction costs "bandwidth" or "energy", but this is usually extremely low compared to Ethereum. Tron has therefore become highly popular and has grown into a top 10 cryptocurrency.

What makes TRC20 popular?

You have probably seen it: many crypto users choose "USDT-TRC20" when sending stablecoins. That is no coincidence. TRC20 has become extremely popular due to three major advantages.

1. Transaction fees are extremely low

A TRC20 transaction often costs less than a few cents. Sometimes almost zero if you have enough staked "bandwidth". This makes it ideal for:

• international payments
• arbitrage
• fast transfers between exchanges

For many users, TRC20 is simply the cheapest way to move value. The network is also well integrated with other blockchains, so you can easily bridge assets to and from the Tron network.

2. Transactions are fast

Where some blockchains take half a minute for a confirmation, Tron is built for high throughput. Transactions are often confirmed within a few seconds.

This gives TRC20 a major advantage for platforms that:

• need real-time responsiveness
• must keep cost structures low
• cannot afford delays

3. Large ecosystems and broad support

Tron is integrated into practically every major exchange. This means TRC20 tokens:

• are easy to trade
• can be transferred quickly between platforms
• have a huge user base

Stablecoins such as USDT run massively on TRC20, which helps the ecosystem grow continuously.

Advantages of TRC20

1. Very low transaction costs
The biggest benefit: TRC20 transactions are almost always cheap, while ERC-20 on Ethereum often has higher fees.

2. Fast transactions and high capacity
The Tron network can process many transactions per second, so delays are rare.

3. EVM compatibility
Developers familiar with Ethereum can easily switch. The development tools are very similar.

4. Large stablecoin adoption
USDT on TRC20 is extremely popular, providing high liquidity and usability in everyday use.

5. Energy-efficient consensus mechanism
Tron uses Delegated Proof of Stake, allowing transactions to be fast and energy efficient.

Disadvantages of TRC20

1. Limited decentralization
The network operates through a small set of "super representatives" who produce blocks. This can be seen as a risk by crypto purists.

2. Dependence on USDT
The success of TRC20 is closely linked to the success of Tether. That offers scale advantages but also creates a potential single point of failure.

3. Smart contract risks
As with all token standards, bugs can exist in the smart contract or there may be vulnerabilities.

4. Less advanced DeFi than Ethereum
Tron does offer DeFi, but it still trails behind Ethereum in innovation and complexity. TRC20 is mainly used as a transaction standard rather than an innovation platform.

What can you do with TRC20 tokens?

TRC20 tokens are used in many ways in practice. Thanks to low costs and high speed, they are particularly suitable for payments, such as international transfers, payroll, e-commerce and B2B transactions. In regions where traditional payment methods are slow or expensive, TRC20 offers an attractive alternative. A significant portion of its usage revolves around stablecoin transfers: USDT on TRC20 has become one of the most popular ways to send digital dollars, especially in countries with high inflation or limited banking access.

TRC20 tokens also play a role in DeFi on Tron. Users can participate in activities such as lending, staking, providing liquidity or yield farming, although the Tron ecosystem is smaller and less advanced than Ethereum’s. Still, it offers plenty of opportunities for those who value simplicity and low cost. Finally, TRC20 is widely supported by major crypto exchanges, making deposits and withdrawals very fast and inexpensive. All of this makes TRC20 a practical and globally used token standard.

Why is TRC20 so cheap?

Low costs come from:

• DPoS consensus model: cheap block production.
• Resource model: users can stake energy and bandwidth.
• High efficiency: Tron is built for scalability.

As a result, transactions rarely end up in long queues.

TRC20 vs ERC-20: the comparison

Although TRC20 looks a lot like ERC-20, there are several important differences.

The standards themselves are technically very similar, but the user experience differs significantly due to the networks they run on.

Are TRC20 tokens safe?

In principle, the Tron network is safe. The standard itself is solid and Tron is technically stable. However, safety always depends on three things:

• The quality of the smart contract
• The reliability of the token issuer
• How safely you manage your wallet

As always in crypto, the technology is only as safe as the weakest link. A project or coin is not automatically trustworthy just because it runs on Tron.

Final thoughts

TRC20 is one of the most widely used token standards in the world, largely due to the explosive growth of USDT on the Tron network. The technology is built on speed, efficiency and low cost, making it exactly what most users want when sending money or managing stablecoins.

The network offers a fast and inexpensive experience, though there are valid concerns about decentralization and dependence on a few major players. Still, TRC20 has become one of the most important components of today’s crypto infrastructure.

In short: TRC20 makes it possible to build tokens on Tron that are predictable, fast, cheap and widely applicable. It is a crucial standard for payments, stablecoins, dApps and the enormous amount of value that moves across the Tron network every day.
