Please refer to here to get started.

Create Template​

Create a simple example contract code written in Move. You can create a sample contract moon_coin by selecting the template option and clicking the Create Template button.

Source Code​

Note that init_module function is executed only once during deployment.

moon_coin.move
module MoonCoin::moon_coin {
use aptos_framework::coin;

    struct MoonCoin {}

    fun init_module(sender: &signer) {
        aptos_framework::managed_coin::initialize<MoonCoin>(
            sender,
            b"Moon Coin",
            b"MOON",
            6,
            false,
        );
    }

    public entry fun register(account: &signer) {
        aptos_framework::managed_coin::register<MoonCoin>(account)
    }

    public entry fun mint(account: &signer, dst_addr: address, amount: u64) {
        aptos_framework::managed_coin::mint<MoonCoin>(account, dst_addr, amount);
    }

    public entry fun burn(account: &signer, amount: u64) {
        aptos_framework::managed_coin::burn<MoonCoin>(account, amount);
    }

    public entry fun transfer(from: &signer, to: address, amount: u64,) {
        coin::transfer<MoonCoin>(from, to, amount);
    }
}

Note that you should replace MoonCoin address _ of your own account address.

Move.toml
[package]
name = "Examples"
version = "0.0.0"

[addresses]
MoonCoin = "_" 

[dependencies]
AptosFramework = { git = "https://github.com/aptos-labs/aptos-core.git", subdir = "aptos-move/framework/aptos-framework/", rev = "main" }

Compile The Source Code​

Check Out Deployed Contract​

After deployment, you can see moon_coin module and functions.

aptos-moon-coin-deployed

Calling Contract Functions​

  1. Call register function to accept deposits of MoonCoin.

    aptos-moon-coin-register

  2. Select mint function. First parameter is the address of receiver for minting coin and second parameter is the amount of minting coin. For now, set your account address for the first parameter because you have already registered above. The receiver should call register before calling mint.

    aptos-moon-coin-mint

  3. Check if the coin have been minted in Aptos Explorer Coins tab.

    aptos-moon-coin-minted

Try more...​

  1. Call burn function and check it out in Aptos Explorer Coins tab.
  2. Create and switch to new account address and try register. Switch to the original address again and transfer or mint to the address you just newly created.
