- USDT is a stablecoin pegged 1:1 to the US dollar.
- The token itself is the same in value, but it exists on different blockchain networks, which affects:
- Transaction fees
- Speed
- Wallet compatibility
- Deposit addresses
2. Main USDT Versions and Differences
| USDT Version | Blockchain | Ticker | Network Fee | Notes |
|---|---|---|---|---|
| USDT-ERC20 | Ethereum | USDT | High gas fees (ETH required) | Widely supported; secure but expensive. |
| USDT-TRC20 | Tron | USDT | Very low (≈$1 or less) | Cheap and fast; popular for exchanges. |
| USDT-BEP20 | Binance Smart Chain (BSC) | USDT | Low fees (paid in BNB) | Works with BSC wallets and DeFi. |
| USDT-OMNI | Bitcoin Omni Layer | USDT | Higher BTC fees | Original USDT; not as common now. |
3. Key Points to Remember
- Value is the same — 1 USDT on TRC20 is still worth 1 USD, same as 1 USDT on ERC20.
- Addresses are not interchangeable — Sending TRC20 USDT to an ERC20 address will result in loss of funds.
- Fees differ — Many people choose TRC20 because it’s cheap and fast, while ERC20 is often used for Ethereum-based platforms.
