After you initiate the transaction on BTTC, the request will be submitted on the target chain. It may take 45 minutes to 3 hours for your asset to be transferred to the target chain depending on the network condition.
After that, the asset needs to be received on the target chain manually or with the help of the Relayer service. This process may take 5 to 30 minutes depending on the target chain. TRON and BSC may require a shorter period. Ethereum may require a longer period due to its characteristics.
