USDT TRC20 Deposit Not Credited on Bybit
As with most exchanges, a Bybit deposit that seems stuck is almost always either still confirming on-chain, or already confirmed and waiting on internal crediting.
Check the transaction hash
Search your transaction hash on TronScan. A SUCCESS status confirms the transfer itself worked — from that point, you're waiting on Bybit's own deposit processing rather than the TRON network.
Confirm you used the TRC20 option
When generating a deposit address on Bybit, make sure TRC20 was explicitly selected as the network — an address generated for a different network won't correctly receive TRC20 funds even if it superficially looks similar.
Escalating to support
If the transaction is confirmed SUCCESS on TronScan and enough time has passed without a credit, contact Bybit support directly with the transaction hash rather than resending — resending won't fix a delay that's already on their side.
