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。

从 Web3j 和 kaia 库(web3j-ext)中导入必要的类。

使用指定的 BAOBAB_URL 创建 Web3j 实例

此外,您还可以更改默认提供商。 例如,使用alchemy提供商。

用它们的密钥对创建 3 个多重签名证书

燃气价格gas 限值**设置

发件人地址设置为已加载凭据的地址

从网络中获取chain ID

接收器地址设置为任何有效地址

获取发件人地址的nonce

设置以传输

将交易类型设置为 VALUE_TRANSFER

为价值转移创建原始交易

使用 3 个凭证 按顺序签署交易

签署的交易发送至 kaia 网络

从签名交易中恢复发件人地址,并将其与收件人地址进行比较

关闭 Web3j 实例
