多用户账户密钥

AccountKeyWeightedMultiSig is an account key type containing a threshold and WeightedPublicKeys which contains a list consisting of a public key and its weight.

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。

从web3py_ext导入extend，将 web3 扩展为 kaia web3

从 web3 和 web3py_ext 导入必要的实用程序

使用指定的 kairos 测试网 URL 创建 Web3 实例

此外，您还可以将提供商 URL 从 kairos 更改为 quicknode 。

使用 Account.from_key 定义 3 个不同的账户

创建一个TxType.ACCOUNT_UPDATE类型的空交易。您可以使用 empty_tx 工具来获取已填写默认字段的 tx。

使用 merge 工具，将 sender 和 keys 等附加字段合并到空 tx 中。

在这种情况下，要更新的账户密钥是 mutisig 密钥，其中每个密钥都包含一个压缩公钥及其权重。 compressed_key 工具将从密钥中提取压缩公钥。

使用 fill_transaction 为交易对象添加更多参数，如 gas 限制...

您可以使用 to_pretty 工具打印格式化的 tx。

签署账户更新 tx 类型。您必须用全部 3 个已加载的账户签名

向网络发送*已签名的交易，并等待接收，直到交易在区块链中完全执行为止
