When sending funds via the Bitcoin network (known as an on-chain transaction), you have the option to enhance the speed of final settlement by paying a fee.

Paying a higher fee will result in your transaction being broadcast in the blockchain more quickly, whereas a lower fee may cause your transaction to take additional time to be broadcast. When initiating your on-chain transaction, you can select between different delivery times.

• Priority: Estimated time is ~10 minutes
• Standard: Estimated time is ~1 hour
• Flexible: Estimated time is ~24 hours

The delivery times are estimated, as Bitcoin blocks can be longer or shorter than the average time of 10 minutes. The Priority and Standard delivery times have fees, whereas the Flexible delivery time does not have a fee.
