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：

从web3py_ext导入extend，将 web3 扩展为 kaia web3

从 web3 和 web3py_ext 导入必要的实用程序

使用指定的 kairos 测试网 URL 创建 Web3 实例

此外，您还可以将提供商 URL 从 kairos 更改为 quicknode 。

从私人密钥加载账户

创建一个TxType.ACCOUNT_UPDATE类型的空交易。您可以使用 empty_tx 工具来获取已填写默认字段的 tx。

使用 merge 工具，将 sender 和 keys 等附加字段合并到空 tx 中。

在这种情况下，要更新的账户密钥是publickey。

您可以使用 compressed_key 工具来设置密钥。它将从密钥中提取压缩公钥

使用 fill_transaction 为交易对象添加更多参数，如 gas 限制...

您可以使用 to_pretty 工具打印格式化的 tx。

签署账户更新 tx 类型。您必须使用已加载的账户签署

向网络发送*已签名的交易，并等待接收，直到交易在区块链中完全执行为止
