ethereum.send()方法返回一个Promise对象，其解析值为JSON-PRC 响应结果。

示例代码

下面的示例展示了如何使用ethereum.send()方法来发送以太币、调用智能合约：

params: [{
  "from": "0xb60e8dd61c5d32be8058bb8eb970870f07233155",
  "to": "0xd46e8dd67c5d32be8058bb8eb970870f07244567",
  "gas": "0x76c0", // 30400
  "gasPrice": "0x9184e72a000", // 10000000000000
  "value": "0x9184e72a", // 2441406250
  "data": "0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"
}]

ethereum.send({
  method: 'eth_sendTransaction',
  params: params,
  from: accounts[0], // Provide the user's account to use.
})
.then(function (result) {
  // The result varies by method, per the JSON RPC API.
  // For example, this method will return a transaction hash on success.
})
.catch(function (reason) {
 // Like a typical promise, returns a reason on rejection.
})
