This repository contains a Sui Move module that implements a generic multi-asset bank. Users can deposit coins of any type and receive a non-transferrable NFT receipt. They can later redeem that receipt to withdraw their deposited funds.
- Generic Deposits: Deposit
Coin<T>where T can be any coin (e.g., SUI, USDC, USDT) - NFT Receipt: NFT token to represent the deposit
- Withdrawal: Redeem NFT to withdraw the exact amount deposited
- Counters: Tracks total deposits and active NFT receipts
A shared Sui object published once via the init (or create_asset_bank for test purposes) function that keeps:
- An unique ID of the bank
- A deposit counter
- A count of currently active (unredeemed) NFTs
An NFT object representing a deposit receipt:
- Non-transferable, only the depositor can redeem it for withdrawal
- Tracks:
