Public Account Key

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 ethers 和 @kaiachain/ethers-ext 软件包，在 ethers.js 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。以太坊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

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。

向区块链发送 tx。函数 "sendTransaction "使用账户的私钥进行内部签名，然后将其传输到区块链网络。

如果已在区块链中完成发送，wait函数将返回发送回执。
