Maiar DEX:对智能契约响应的erdpy查询为空

Question

我试图使用erdpy在testnet上找到对EGLD的地址。

我用这个电话：

erdpy --verbose contract query erd1qqqqqqqqqqqqqpgqum3tp4paqxt3snyfj3a5qj37tr9umv970n4s0kv06c --proxy https://testnet-gateway.elrond.com --function=getPair --arguments 0x5745474C442D663634336438 0x4D45582D633735316436

哪里

erd1qqqqqqqqqqqqqpgqum3tp4paqxt3snyfj3a5qj37tr9umv970n4s0kv06c是测试网上路由器智能协议的地址。我在https://testnet.maiar.exchange/中执行交换时发现了它，如图所示

​

0x5745474C442D663634336438在十六进制中是wegd-f643d8。

0x4D45582D633735316436在十六进制中为MEX-c751d6。

此呼叫的响应为空。

我做错什么了？

Answer 1

您使用的地址不是您假设的路由器地址，而是对本身的地址。

您还可以通过graphql轻松地检查这一点。https://testnet-exchange-graph.elrond.com/graphql

使用以下查询：

{factory{address}, pairs{address, firstToken{identifier}, secondToken{identifier}}}

您将收到以下输出：

{
  "data": {
    "factory": {
      "address": "erd1qqqqqqqqqqqqqpgq4axqc749vuqr27snr8d8qgvlmz44chsr0n4sm4a72g"
    },
    "pairs": [
      {
        "address": "erd1qqqqqqqqqqqqqpgqum3tp4paqxt3snyfj3a5qj37tr9umv970n4s0kv06c",
        "firstToken": {
          "identifier": "WEGLD-f643d8"
        },
        "secondToken": {
          "identifier": "MEX-c751d6"
        }
      },
      {
        "address": "erd1qqqqqqqqqqqqqpgqmzjpcyra47d0k8xualwcs6k2gzkdrdap0n4sdj0nu6",
        "firstToken": {
          "identifier": "WEGLD-f643d8"
        },
        "secondToken": {
          "identifier": "USDC-72a225"
        }
      },
      {
        "address": "erd1qqqqqqqqqqqqqpgq3cpwrvmextk986e6z6akeewq8feukuj90n4sf2aa2n",
        "firstToken": {
          "identifier": "WEGLD-f643d8"
        },
        "secondToken": {
          "identifier": "RIDE-ae50f0"
        }
      }
    ]
  }
}

其中，工厂地址是代理，而这对地址应该是不言自明的。
