When making a send, users can adjust the network fee by tapping on the “Fee:” portion of the send screen. Tappable portions of the app are indicated by the mint colored right facing arrow (>).
Fees are presented to users with four available options:
High
The high fee setting aims to confirm a transaction in the next block. Edge achieves this by referencing the last confirmed block and multiplying that block’s fee by 2.
Optimal
The optimal fee setting aims to confirm a transaction within the next three blocks. Edge achieves this by referencing the last confirmed block and then adding 30% to prevent the transaction from getting stuck with rapid fee movements.
Low
The low fee setting aims to confirm within the next six blocks and takes an average of the last two blocks confirmed as the fee used.
Custom
The custom fee setting allows users to set the fee they would like to use. NOTE: setting too low of a fee can cause stuck transactions or dropped/failed transactions.
Once you select the desired option you can then tap “Done” and then slide to confirm.
*Edge update 3.17.2 adjusted the optimal BTC fee by adding 30%. Users may see higher fees now, with the intention of preventing stuck transactions.
