This is a smart contract to facilitate the safe distribution of Button ($BTN) on Aleph Zero. It is the final step of the Button ($BUTT) migration from Secret Network. All minted $BTN will be initially sent to this smart contract. With the amount and address details collected from the Secret Network migration contract, we will increase the account allowances accordingly.
- Initialise with admin and $BTN smart contract details.
- Allow admin to increase_allowance for an account and store the details. The key for details is a String as it will be an encryption of the corresponding Secret Network migration order id.
- Allow admin to decrease_allowance for an order and remove the details. This is in case the user has entered the wrong address.
- Allow user to collect their $BTN.
- Allow retrieving order details.
