So, let’s use the top-left participant (P1) to switch tokens to a different participant. Bear in mind, all of them use the identical tackle; therefore, all of them will obtain tokens. After clicking on one other participant, the sender will get to decide on which tokens to ship. Furthermore, the interface additionally shows the addresses concerned in a possible transaction:
As soon as the participant selects which property to ship, the participant should verify the transaction utilizing their pockets (the linked pockets):
The “Ready For Transaction” message seems after confirming the transaction with the linked pockets:
Lastly, after confirming the on-chain transaction, the recipient first receives a message:
Quickly after the message arrives, the recipient additionally receives tokens, that are mirrored within the participant’s stability (from 150 to 175):
After all, the identical applies when transferring prizes (ERC-721 NFTs).
