多用戶賬戶密鑰

AccountKeyWeightedMultiSig 是一種賬戶密鑰類型，包含一個閾值和加權公鑰（WeightedPublicKeys），後者包含一個由公鑰及其權重組成的列表。

要使與 AccountKeyWeightedMultiSig 關聯的賬戶的交易有效，必須滿足以下條件： 已簽名公鑰的加權和應大於閾值。 _ 無效簽名不應包含在交易中。 * 已簽名公鑰的數量應少於加權公鑰的數量。

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

定義發件人的地址、私人密鑰和其他加權多重簽名私人密鑰

定義接收方的地址

使用指定的 kairos 測試網 URL 設置提供程序。 web3js 中的提供者是訪問區塊鏈數據的只讀抽象。

此外，您還可以將提供商 URL 從 kairos 更改為 quicknode

使用提供程序定義Web3 實例

使用加權多重簽名私鑰和提供商創建 3 個不同的錢包

創建具有 type：TxType.ValueTransfer 類型

使用首個錢包簽署交易

用第二個錢包簽署交易

用第三個錢包簽署交易

將簽署的交易發送到 kaia 網絡，並打印收據

使用 web3.klay.recoverFromTransaction 從已簽署的事務中恢復地址
