TxTypeValueTransfer 用于用户发送 KAIA。

• 由于 kaia 提供了多种交易类型，使每种交易类型只服务于一个目的，因此 TxTypeValueTransfer 只限于将 KAIA 发送到外部拥有的账户（EOA）。

导入 web3 和 @kaiachain/web3js-ext 软件包，在 web3 上添加 kaia 功能

定义发送方、接收方地址和发送方私人密钥

使用指定的 kairos 测试网 URL 设置提供程序。 web3js 中的提供者是访问区块链数据的只读抽象。

此外，您还可以更改默认提供商。 例如，使用alchemy提供者。

使用提供程序创建KlaytnWeb3实例

声明事务参数，如 ** 类型、从、到、值**

用发送方账户签署交易

将已签名的交易发送到区块链，并打印收据
