多用户账户密钥

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**@kaiachain/web3js-ext**软件包，在 web3 上添加 kaia 功能

定义要更改的发件人地址、发件人私人密钥和新的muti-sig 私人密钥

使用指定的 kairos 测试网 URL 设置提供程序。 web3js 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

使用提供程序定义Web3 实例

用私钥和提供者创建三个发送者钱包

用新私钥计算公钥

声明一个事务，该事务的键字段包含计算出的公钥及其权重，指定类型为加权多重签名。

与第一个钱包签署交易

与第二个钱包签署交易

与第三个钱包签署交易

向 kaia 网络发送交易，如果交易在区块链中完成，则返回 tx 收据。
