Multisig Account Key

AccountKeyWeightedMultiSig 是一种账户密钥类型，包含一个阈值和加权公钥（WeightedPublicKeys），后者包含一个由公钥及其权重组成的列表。

要使与 AccountKeyWeightedMultiSig 关联的账户的交易有效，必须满足以下条件： 已签名公钥的加权和应大于阈值。 _ 无效签名不应包含在交易中。 * 已签名公钥的数量应少于加权公钥的数量。

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

定义发件人的地址、私人密钥和其他加权多重签名私人密钥

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

使用加权多重签名私钥和提供商创建 3 个不同的钱包

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

用第一个钱包签署交易，"populateTransaction "方法为交易对象添加更多参数，如gas、nonce...

用第二个钱包签署交易

在第三个钱包中签署交易，并将签署的交易发送至 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
