基于角色的账户密钥

AccountKeyRoleBased 表示基于角色的密钥。 如果账户有一个基于账户密钥角色的对象,且交易类型为除账户更新外的,那么验证过程将根据每个角色进行,如下所示:

导入 ethers@kaiachain/ethers-ext 软件包,在 ethers.js 上添加 kaia 功能

定义发件人的地址和基于角色的私人密钥

定义接收方的地址

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的钱包

type.TxType.ValueTransfer 创建一个值转移事务,以便以后用 klay_recoverFromTransaction 恢复:TxType.ValueTransfer",以便以后使用 "klay_recoverFromTransaction "恢复它

与具有发送交易角色的钱包签署交易,"populateTransaction "方法为交易对象添加更多参数,如gas、nonce...

签署的交易发送至 kaia 网络

等待交易完成并打印收据

使用 klay_recoverFromMessage 从已签署的事务中恢复地址

SignTxWithRoleBasedExample.js

const { ethers } = require("ethers");
const { Wallet, TxType, parseKlay } = require("@kaiachain/ethers-ext");
const senderAddr = "0x5bd2fb3c21564c023a4a735935a2b7a238c4ccea";
