Omni USDT and BTC wallet addresses on Bybit are unique and different.

Even though they are on the same BTC blockchain, you cannot deposit Omni USDT to BTC wallet address.

If you unintentionally deposited real coin into your testnet wallet address, go to the wallet that was used to make the deposit and attempt to obtain the transaction hash (TXID).

Then contact Bybit’s support team provide them with the coin type, coin amount and TXID and Bybit will attempt a recovery on a best effort basis.
