Giftcard
Create a giftcard with native tokens
Giftcard contract allows users to create a transactions to lock assets into the smart contract, which can be redeemed by any user.
Creating a giftcard will mint a token and send the assets to the contract. While redeeming will burn the token and send the assets to the redeemer.
There are 2 actions (or endpoints) available to interact with this smart contract:
