You've likely encountered terms like USDT-TRC20 or ERC20—two of the most popular formats for Tether's stablecoin. Tether (USDT) remains one of the most widely used stablecoins in the cryptocurrency market. Initially launched on the Bitcoin blockchain using the OMNI Layer protocol, USDT has since expanded to multiple blockchains, each offering unique advantages.
In this article, we'll break down everything you need to know about TRC-20 and ERC-20, including their differences, benefits, and use cases. Let's dive in!
What Is Tether (USDT)?
Tether is a stablecoin pegged 1:1 to fiat currencies. For example:
- USDT: Pegged to the US dollar
- EURT: Pegged to the euro
- CNHT: Pegged to the Chinese yuan
Issued by Tether Limited, the company claims its tokens are 100% backed by reserves, making USDT less volatile than other cryptocurrencies.
USDT Variants Across Blockchains:
- OMNI: Issued on the Bitcoin blockchain
- ERC20: Issued on the Ethereum blockchain
- TRC20: Issued on the Tron blockchain
- BEP2: Issued on the Binance Chain
- BEP20: Issued on the Binance Smart Chain
Tether also offers a gold-backed stablecoin, Tether Gold (XAUT), which is pegged to the value of gold.
USDT ERC-20 vs. TRC-20: Key Differences
ERC-20 USDT:
- Launched in February 2018 on Ethereum
- Enables smart contract functionality and decentralized applications (dApps)
- Slow transaction speeds and high gas fees due to Ethereum network congestion
TRC-20 USDT:
- Launched in April 2019 on the Tron blockchain
- Ultra-low transaction fees (often free)
- Faster confirmations (seconds vs. minutes/hours)
