Legacy Account Key

AccountKeyLegacy

從web3py_ext導入extend，將 web3 擴展為 kaia web3

從 eth_account、web3py_ext 和 cytools 中導入必要的實用程序

使用指定的 kairos 測試網 URL 創建 Web3 實例

此外，您還可以將提供商 URL 從 kairos 更改為 quicknode 。

從私人密鑰加載賬戶

創建一個TxType.ACCOUNT_UPDATE類型的空交易。您可以使用 empty_tx 工具來獲取已填寫默認字段的 tx。

使用 merge 工具，將 sender 和 keys 等附加字段合併到空 tx 中。

在這種情況下，要更新的賬戶密鑰是** legacy**密鑰。

使用 fill_transaction 為交易對象添加更多參數，如 gas 限制...

您可以使用 to_pretty 工具打印格式化的 tx。

簽署賬戶更新 tx 類型。您必須使用已加載的賬戶簽署

向網絡發送*已簽名的交易，並等待接收，直到交易在區塊鏈中完全執行為止
