更新账户

Import extend from web3py_ext to extend web3 to kaia web3

Import necessary utils from eth_account, web3py_ext and cytools

Create a Web3 instance with the specified kairos testnet URL

Also, you can change the provider URL from kairos to quicknode.

Load transaction key from a private key to use it as transaction role key. 您可以用它来签署交易

Load update key from a private key to use it as update role key. 您可以用它来签署该账户的账户更新交易。这意味着只有拥有此密钥的人才能更新此账户。 z

从私人密钥中加载缴费人密钥，将其用作缴费人角色密钥。您可以用它作为付费方签署交易。

从私人密钥加载 ** fee_delegator** 密钥

创建TxType.FEE_DELEGATED_ACCOUNT_UPDATE类型的空事务。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基于角色的密钥，每个角色都有公钥类型。每个角色都可以使用发布密钥或多重身份验证。

您可以使用 compressed_key 工具来设置每个角色的密钥。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。您应使用 ** 更新角色密钥** 签名，因为账户 "0x5bd2...cea "已是基于角色的账户，以更新该账户

Recovering the sender's address from the signed transaction

If you want to see the RLP-encoded signed tx, use the decode_transaction util

使用收费委托人账户签署signed_tx.rawTransaction。

从已签署的交易中恢复收费委托人的地址

If you want to see the RLP-encoded signed tx, use the decode_transaction util

使用收费委托人账户向网络发送*已签署的交易，并等待接收，直到交易在区块链中完全执行为止
