公共账户密钥
AccountKeyPublic 用于有一个公钥的账户。 如果账户有一个 AccountKeyPublic 对象,交易验证过程如下:
导入**@kaiachain/web3js-ext**软件包,在 web3 上添加 kaia 功能
定义要更改的发件人地址、发件人私人密钥和新私人密钥
使用指定的 kairos 测试网 URL 设置提供程序。 web3js 中的提供者是访问区块链数据的只读抽象。
此外,您还可以将提供商 URL 从 kairos 更改为 quicknode
使用提供程序定义Web3 实例
用私钥和提供者创建发件人钱包
用新私钥计算公钥
声明一个事务,其类型为 账户密钥类型.公钥,密钥字段为新计算的公钥。
用发件人的钱包签署交易
向区块链发送已签名的 tx。 它将返回交易的收据
