Why does USDT exist in ERC20 and TRC20? Both standards explained

You may have noticed that there are two main versions of USDT on the market, one operating on the ERC20 standard and the other on the TRC20 standard. This difference may seem confusing at first, but understanding these two versions of USDT is essential for effective trading and saving on transaction fees.

Why Are There Two USDT Standards?

USDT does not exist on a single blockchain network. This is a crucial point to understand: the same cryptocurrency can circulate on multiple different blockchain networks, much like the same currency issued by two different central banks, each operating within its own system.

The company Tether has chosen to launch USDT on two of the world’s largest blockchain networks: Ethereum and Tron. Each network has its own technical characteristics, associated fees, and performance. That’s why USDT adapts to these two environments by using the native standards of each blockchain.

USDT ERC20: The Ethereum Standard

The ERC20 standard is the primary format for tokens built on the Ethereum blockchain. When you send or receive USDT ERC20, your transaction is executed on the Ethereum network, also called “Ether.”

This standard offers maximum compatibility with Ethereum’s DeFi ecosystem and many decentralized protocols. However, ERC20 transactions usually involve higher gas fees, especially during network congestion. This approach is often preferred for large transfers or when maximum Ethereum security is a priority.

USDT TRC20: The Tron Standard and Its Benefits

The TRC20 standard operates on the Tron blockchain, the blockchain network created by the Tron Foundation. USDT TRC20 transactions benefit from a significantly lower fee structure compared to ERC20. Costs are drastically reduced, making it the preferred choice for frequent transfers and small amounts.

Tron also offers faster confirmation speeds and better scalability. Many trading platforms, including Gate.io, facilitate deposits and withdrawals in USDT TRC20 precisely for these reasons: to minimize costs for users and speed up transactions.

How to Distinguish and Choose Between Them?

Identifying the difference between USDT ERC20 and TRC20 is simple: each version features a distinctive logo. When checking your wallet or exchange platform, you will clearly see the network associated with each USDT.

Here’s how to choose:

• Opt for USDT TRC20 if you make regular transfers, small amounts, or want to reduce your transaction fees.
• Prefer USDT ERC20 if you interact heavily with Ethereum-based DeFi protocols or value Ethereum’s historical security.

Both standards maintain the same value (1 USDT = 1 USD), but your choice will depend entirely on your specific needs. Understanding these two variants of the ERC20 and TRC20 standards will help you optimize your transactions and save on network fees.
