Lisk Smart Contract
Foundry

Triển khai smart contract trên Lisk sử dụng Foundry

Lưu ý 1: Cài đặt lệnh curl trước khi bắt đầu

Lưu ý 2: Wallet deploy contract cần có balance trên Lisk Testnet

Cài đặt Foundry

  • Đối với MacOS hoặc Linux/Ubuntu

Run command:

curl -L https://foundry.paradigm.xyz | bash

Cài đặt thư viện mới nhất Foundry

foundryup
  • Đối với Windows

Lưu ý: Cài đặt Ubuntu WSL: https://documentation.ubuntu.com/wsl/latest/howto/install-ubuntu-wsl2/ (opens in a new tab)

Sau đó chạy lệnh tương tự như MacOS hoặc Linux/Ubuntu

Tạo project Foundry

forge init foundry_app && cd foundry_app

Tạo smart contract ERC20

  1. Cài đặt thư viện openzeppelin
forge install openzeppelin/openzeppelin-contracts
  1. Tạo file src/ERC20.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.23;
 
import "openzeppelin-contracts/contracts/token/ERC20/ERC20.sol";
 
contract MyToken is ERC20 {
    constructor() ERC20("MyToken", "MT") {
        _mint(msg.sender, 1000000 * (10 ** uint256(decimals())));
    }
}
  1. Compile smart contract ERC20
forge build
  1. Test smart contract ERC20
