Ways we support FEVM transactions:

FEVM->FEVM (Should be working on all platforms)

1) Create new Ethereum account 2) This account can be used to receive FEVM tokens 3) You can now use FEVM tokens at the "Send" screen: image image 4) FEVM balance is also displayed as part of ETH address assets: image

FVM->FEVM (Desktop)

1) To send from FVM to FEVM select Filecoin account on the "Send screen": image 2) You can now select FEVM address as a recipient: image Both FEVM and f4 form is shown for such addresses because f4 will be used in the transaction. You can also manually type FEVM or f4 address to the input. 3) Warning message is shown in case FEVM address is selected\typed: image 4) Transaction uses f4 address as a recipient: image 5) Transaction appears at the "Account details" screen (TBD print FEVM form or match existing account here): image
