To help you determine whether your USDT is ERC20 or TRC20, let’s first look at the differences between these two standards and how you can easily check which one applies to your USDT.

Understanding ERC20 vs TRC20

  • ERC20: This is a token standard built on the Ethereum blockchain. It’s widely used for many types of tokens, including USDT (Tether) on Ethereum. ERC20 tokens are part of the Ethereum network, which means they benefit from its strong security but can come with higher fees and slower transaction times.
  • TRC20: This standard is built on the TRON blockchain. TRC20 tokens, like USDT on TRON, generally offer faster transactions and lower fees compared to ERC20, but they are separate from Ethereum’s ecosystem.

How to Identify Whether Your USDT is ERC20 or TRC20

  1. Check the Network on the Wallet/Exchange:
    • When you send USDT, most platforms (like Binance, Coinbase, or your wallet app) will show you the network options. You’ll usually see choices like Ethereum (ERC20) or TRON (TRC20).
    • If you’re unsure, check your wallet or exchange settings to see which network your USDT is stored on.
  2. Look at the Address Format:
    • ERC20 addresses are typically on the Ethereum network and start with 0x. So, if your USDT address starts with 0x, it’s most likely ERC20.
    • TRC20 addresses on the TRON network usually start with T (e.g., TXYZ...). If your address starts with T, it’s TRC20.
  3. Transaction Fees and Speed:
    • ERC20 transfers usually come with higher fees and slower transaction speeds due to Ethereum’s network congestion.
    • TRC20 transfers are typically faster and cheaper, thanks to the TRON network’s lower transaction costs.

How to Check:

  • Step 1: Go to your wallet or exchange where your USDT is stored.
  • Step 2: Check the network listed for your USDT balance or any pending transactions. If it’s Ethereum, it’s ERC20. If it’s TRON, it’s TRC20.

Quick Summary:

  • ERC20: Ethereum network, starts with 0x, higher fees, slower transactions.
  • TRC20: TRON network, starts with T, lower fees, faster transactions.

By following these simple steps, you should be able to easily identify whether your USDT is ERC20 or TRC20 and proceed with your transactions smoothly.
