01. 以太坊部署智能合约

创建合约

mkdir contracts

vi HelloETH.sol

pragma solidity ^0.8.7;
contract HelloETH {
  function rate(uint a, uint b) public pure returns (uint){
    return a * b;
  }
}

安装 solc

前提安装 npm

apt-get install npm

npm install -g solc --registry=https://registry.npm.taobao.org

solcjs --version
0.8.7+commit.e28d00a7.Emscripten.clang

编译

solcjs --bin HelloETH.sol
