基於角色的賬戶密鑰

AccountKeyRoleBased 表示基於角色的密鑰。 如果賬戶有一個基於賬戶密鑰角色的對象,且交易類型為除賬戶更新外的,那麼驗證過程將根據每個角色進行,如下所示:

導入 ethers@kaiachain/ethers-ext 軟件包,在 ethers.js 上添加 kaia 功能

定義要更改的發件人地址、發件人私人密鑰和新的基於角色的私人密鑰

使用指定的 Kairos 測試網 URL 設置提供程序。 以太坊中的提供者是訪問區塊鏈數據的只讀抽象。

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

使用更新者角色私鑰和提供者創建發送者錢包

根據新的基於角色的私鑰計算**公鑰

密鑰字段中使用計算出的基於角色的公鑰聲明一個事務

向區塊鏈發送 tx。 函數 "sendTransaction "使用賬戶的私鑰進行內部簽名,然後將其傳輸到區塊鏈網絡。

如果已在區塊鏈中完成發送,wait函數將返回發送回執。
