本节主要就是一个新手教学，让人先了解游戏玩法及闯关模式，需要对 MetaMask、JavaScript、console等有基本了解。 打开 Developer Console (F12) ，输入会打印当前钱包地址。 依步骤了解指令用法，按 Get new instance 开始闯关。MetaMask 会弹出交易请求，确认以部署关卡合约，关卡正式开始。 打开 Developer Console (F12) ，依次输入:> await contract.info() < "You will find what you need in info1()." > await contract.info1() < "Try info2(), but with "hello" as a parameter." > await contract.info2("hello") < "The property infoNum holds the number of the next info method to call." > await contract.infoNum() < BN {negative: 0, words: [42, empty], length: 1, red: null} > await contract.info42() < "theMethodName is the name of the next method." > await contract.theMethodName() < "The method name is method7123949." > await contract.method7123949() < "If you know the password, submit it to authenticate()." > await contract.password() < "ethernaut0" > await contract.authenticate("ethernaut0") 最后会弹出一个 MetaMask 的交易请求，确认后再按 Submit instance，再确认后 Console 会弹出 “You have completed this level!!!” 即本关完成。
