Which type of USDT do I have?
There are several methods to check which type of USDT you have in your account.
- Check the withdrawal address
- ERC20-based USDT will begin with an “0x”
- Omni Layer-based USDT will begin with a random string of numbers or letters, most often starting with either “1”, “3” or the new SegWit prefix “bc1”.
- Check with the exchange
- Contact the customer support of the exchange you wish to withdraw from and check which type of USDT they host.
- Test the wallet with a small amount
- You should only use this as a last resort since it may result in a loss of funds (albeit a small amount). If you cannot confirm the type of USDT you have, you can always send a very small amount to a USDT wallet to figure out if you have the type that wallet supports. If the funds arrive, then you have the same type of USDT supported by that wallet. If they are lost, then you may assume you have the other type and should perform the same check with the other wallet type to be sure.
