TxTypeLegacyTransaction 代表 kaia 以前存在的一种事务类型。

**这种类型的交易可以创建账户、转移代币、部署智能合约、执行智能合约，或者执行上述交易的混合。

导入可与以太坊区块链及其生态系统交互的ethers软件包。

导入 @kaiachain/ethers-ext 软件包，在 ethers.js 上添加 kaia 功能

定义发送方地址、发送方私人密钥和接收方地址

使用指定的 kairos 测试网 URL 设置提供程序。以太坊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

使用私钥和提供商启动钱包实例。

声明一个事务，其字段包括from（从）、to（到）、value（值）。

向区块链发送 tx。函数 "sendTransaction "使用账户的私钥进行内部签名，然后将其传输到区块链网络。

如果已在区块链中完成发送，wait函数将返回发送回执。
