代币合约

合约参数

保存代币余额
代码语言：javascript复制
struct Coin has store {
    value : u128,
}
地址对印余额数据
代码语言：javascript复制
struct CoinStore has key {
    coin : Coin,
}
代币基础信息
代码语言：javascript复制
struct CoinInfo has key {
    // 名称
    name: string::String,
    // 符号
    symbol: string::String,
    // 精度
    decimals: u8,
    // 总发行量
    supply: u128,
    // 已发行量
    cap: u128,
}

assert 错误信息定义

assert只能给定 u64 错误信息，全局错误定义

代码语言：javascript复制
// 账户已经注册
const THE_ACCOUNT_HAS_BEEN_REGISTERED : u64 = 1;
// 无效的令牌所有者
const INVALID_TOKEN_OWNER : u64 = 2;
// 账户未注册
const THE_ACCOUNT_IS_NOT_REGISTERED : u64 = 3;
// 余额不足
const INSUFFICIENT_BALANCE : u64 = 4;
// 代币信息已发布
const ECOIN_INFO_ALREADY_PUBLISHED : u64 = 5;
// 超过总供应量
const EXCEEDING_THE_TOTAL_SUPPLY : u64 = 6;

合约查询方法

查询代币余额
代码语言：javascript复制
public fun getBalance(owner: address) : u128 acquires CoinStore{
    // 确定帐户是否已注册
    assert!(is_account_registered(owner), THE_ACCOUNT_IS_NOT_REGISTERED);
    // 返回余额
    borrow_global<CoinStore>(owner).coin.value
}
查询帐户是否已注册
代码语言：javascript复制
public fun is_account_registered(account_addr : address) : bool{
    exists<CoinStore>(account_addr)
}

合约公共方法

增加地址余额

代码语言：javascript复制
fun deposit(account_addr : address, coin : Coin) acquires CoinStore {
    // 确定该帐户是否已注册
    assert!(is_account_registered(account_addr), THE_ACCOUNT_IS_NOT_REGISTERED);
    // 转账之前余额
    let balance = getBalance(account_addr);
    // 获取可变资源余额
    let balance_ref = &mut borrow_global_mut<CoinStore>(account_addr).coin.value;
    // 更新余额
    *balance_ref = balance   coin.value;
    // 销毁资源
    let Coin { value:_ } = coin;
}

减少地址余额

代码语言：javascript复制
fun withdraw(account_addr : address, amount : u128) : Coin acquires CoinStore {
    // 确定该帐户是否已注册
    assert!(is_account_registered(account_addr), THE_ACCOUNT_IS_NOT_REGISTERED);
    // 转账之前余额
    let balance = getBalance(account_addr);
    // 余额是否足够
    assert!(balance >= amount, INSUFFICIENT_BALANCE);
    // 获取可变资源余额
    let balance_ref = &mut borrow_global_mut<CoinStore>(account_addr).coin.value;
    // 更新余额
    *balance_ref = balance - amount;
    // 返回余额资源
    Coin { value: amount }
}

合约执行函数

初始化代币信息

代码语言：javascript复制
public entry fun initialize(address : &signer, name : vector<u8>, symbol : vector<u8>, decimals : u8, supply : u128)  {
    // 是否有权限初始化代币信息
    assert!(signer::address_of(address) == MODULE_OWNER, INVALID_TOKEN_OWNER);
    // 确定是否已初始化(防止重复初始化)
    assert!(!exists<CoinInfo>(MODULE_OWNER), ECOIN_INFO_ALREADY_PUBLISHED);
    // 创建令牌信息
    move_to(address, CoinInfo{name : string::utf8(name), symbol : string::utf8(symbol), decimals, supply, cap : 0});
}

address：调用用者，name：名称，symbol：符号，decimals：精度，supply：总发行量

注册账号(在交易之前必须先注册账号)

代码语言：javascript复制
public entry fun register(address : &signer) {
    let account = signer::address_of(address);
    // 确定该帐户是否已注册(防止重复注册)
    assert!(!exists<CoinStore>(account), THE_ACCOUNT_HAS_BEEN_REGISTERED);
    // 初始化账号
    move_to(address, CoinStore{ coin : Coin{ value : 0 } });
}

铸币

代码语言：javascript复制
public entry fun mint(owner : &signer,to : address,amount : u128) acquires CoinStore,CoinInfo{
    // 是否有权限铸币
    assert!(signer::address_of(owner) == MODULE_OWNER, INVALID_TOKEN_OWNER);
    // 是否超过总发行量
    assert!(borrow_global<CoinInfo>(MODULE_OWNER).cap   amount <= borrow_global<CoinInfo>(MODULE_OWNER).supply,EXCEEDING_THE_TOTAL_SUPPLY);
    // 收款人增加余额
    deposit(to, Coin { value : amount });
    // 增加发行总量
    let cap = &mut borrow_global_mut<CoinInfo>(MODULE_OWNER).cap;
    *cap = *cap   amount;
}

owner：必须为模块拥有者才能有权限铸币，to：给 to 地址铸币，amount：铸币数量

转账

代码语言：javascript复制
public entry fun transfer(from : &signer, to : address, amount : u128) acquires CoinStore {
    // 先扣除账号余额
    let coin = withdraw(signer::address_of(from), amount);
    // 增加账号余额
    deposit(to, coin);
}

销毁

代码语言：javascript复制
public entry fun burn(owner : &signer, amount : u128) acquires CoinStore,CoinInfo {
    // 是否有权限销毁
    assert!(signer::address_of(owner) == MODULE_OWNER, INVALID_TOKEN_OWNER);
    // 扣除账号余额
    let coin = withdraw(signer::address_of(owner), amount);
    let Coin { value: amount } = coin;
    // 减少已发行量
    let cap = &mut borrow_global_mut<CoinInfo>(MODULE_OWNER).cap;
    *cap = *cap - amount;
    // 减少总发行量
    let supply = &mut borrow_global_mut<CoinInfo>(MODULE_OWNER).supply;
    *supply = *supply - amount;
}

Typescript 脚本

生成账号脚本

account_script.ts

代码语言：javascript复制
//节点URL  REST API地址
export const NODE_URL = "https://fullnode.devnet.aptoslabs.com";
//水龙头URL
export const FAUCET_URL = "https://faucet.devnet.aptoslabs.com";

//生成账号接口
import { AptosAccount, MaybeHexString } from "aptos";

//Aptos客户端 水龙头客户端
import { AptosClient, FaucetClient } from "aptos";

//创建节点客户端
const client = new AptosClient(NODE_URL);

//查询主链币余额
export async function accountBalance(accountAddress: MaybeHexString): Promise<number | null> {
  const resource = await client.getAccountResource(accountAddress, "0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>");
  if (resource == null) {
    return null;
  }

  return parseInt((resource.data as any)["coin"]["value"]);
}

//主方法
async function main() {
  //创建帐户
  const account = new AptosAccount();

  console.log("n=== 地址 ===");
  console.log(
    `地址: ${account.address()} key种子: ${Buffer.from(account.signingKey.secretKey).toString("hex").slice(0, 64)}`,
  );
  //水龙头领取代币
  const faucetClient = new FaucetClient(NODE_URL, FAUCET_URL);
  await faucetClient.fundAccount(account.address(), 50000);

  console.log("n=== 账户余额 ===");
  console.log(`${account.address()}余额: ${await accountBalance(account.address())}`);
}
