Vending Machine

An example project for writing Arbitrum Stylus programs in Rust using the stylus-sdk. It includes a Rust implementation of a vending machine Ethereum smart contract.

distribute Cupcakes to any given address
count Cupcakes balance of any given address

Here is the interface for Vending Machine.

1interface IVendingMachine {
2    // Function to distribute a cupcake to a user
3    function giveCupcakeTo(address userAddress) external returns (bool);
4
5    // Getter function for the cupcake balance of a user
6    function getCupcakeBalanceFor(address userAddress) external view returns (uint);
7}

1interface IVendingMachine {
2    // Function to distribute a cupcake to a user
3    function giveCupcakeTo(address userAddress) external returns (bool);
4
5    // Getter function for the cupcake balance of a user
6    function getCupcakeBalanceFor(address userAddress) external view returns (uint);
7}
