Legacy

TxTypeLegacyTransaction represents a type of transactions existed previously in kaia.

This type of transaction can create an account, transfer tokens, deploy a smart contract, execute a smart contract, or perform a mix of aforementioned.

導入可與以太坊區塊鏈及其生態系統交互的ethers軟件包。

導入 @kaiachain/ethers-ext 軟件包，在 ethers.js 上添加 kaia 功能

定義發送方地址、發送方私人密鑰和接收方地址

使用指定的 kairos 測試網 URL 設置提供程序。 以太坊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

使用私鑰和提供商啟動錢包實例。

聲明一個事務，其字段包括from（從）、to（到）、value（值）。

向區塊鏈發送 tx。 函數 "sendTransaction "使用賬戶的私鑰進行內部簽名，然後將其傳輸到區塊鏈網絡。

如果已在區塊鏈中完成發送，wait函數將返回發送回執。

const ethers = require("ethers");

// when type is empty it will be automatically set to type 0 or 2

// depending on the gasPrice, maxFeePerGas, maxPriorityFeePerGas fields.

// here, type will be 2 because no gas-related fields are set.
