Base Jump API

In this section we will see how we can use the Transaction and Calls API from Bitquery to get info about trades on Base Jump using one of the token address traded on the platform. For this section the token address is the following - 0xEfC79f30b56f36bc49Bf47e8Dccf969fFF214EeD.

Get Base Jump Address

Firstly, we can find the smart contract address of the Base Jump using this query.

query MyQuery {
  EVM(network: base) {
    Events(
      where: {Arguments: {includes: {Value: {Address: {is: "0xEfC79f30b56f36bc49Bf47e8Dccf969fFF214EeD"}}}}}
    ) {
      Arguments {
        Name
        Type
        Value {
          ... on EVM_ABI_Integer_Value_Arg {
            integer
          }
          ... on EVM_ABI_String_Value_Arg {
            string
          }
          ... on EVM_ABI_Address_Value_Arg {
            address
          }
          ... on EVM_ABI_BigInt_Value_Arg {
            bigInteger
          }
          ... on EVM_ABI_Bytes_Value_Arg {
            hex
          }
          ... on EVM_ABI_Boolean_Value_Arg {
            bool
          }
        }
      }
      Transaction {
        From
        To
      }
      count
    }
  }
}

The address labeled as To under the Transaction block is the smart contract address of Base Jump. The Base Jump address is - 0x31C0282Fa6D0A82aD22ab63BbaCd87F62B2a9bfD.

Get All the Methods for Base Jump

We need to get all methods for the Base Jump for better understanding of its functionality and get the signatures used for buying tokens. This query returns all the methods associated with the Base Jump.

query MyQuery {
  EVM(network: base) {
    Calls(
      where: {Transaction: {To: {is: "0x31C0282Fa6D0A82aD22ab63BbaCd87F62B2a9bfD"}}}
      orderBy: {descendingByField: "count"}
    ) {
      Call {
        Signature {
          Name
          Signature
        }
      }
      count
    }
  }
}

From the results we get a signature named swap that will be analysed to get the trades on Base Jump.

Get Trades for Base Jump

This query returns the swap method Calls to the Base Jump that are potentially the trades on the Base Jump.

query MyQuery {
  EVM(network: base) {
    Calls(
      where: {Transaction: {To: {is: "0x31C0282Fa6D0A82aD22ab63BbaCd87F62B2a9bfD"}}, Call: {Signature: {Name: {is: "swap"}}}}
    ) {
      Arguments {
        Name
        Type
        Value {
          ... on EVM_ABI_Integer_Value_Arg {
            integer
          }
          ... on EVM_ABI_String_Value_Arg {
            string
          }
          ... on EVM_ABI_Address_Value_Arg {
            address
          }
          ... on EVM_ABI_BigInt_Value_Arg {
            bigInteger
          }
          ... on EVM_ABI_Bytes_Value_Arg {
            hex
          }
          ... on EVM_ABI_Boolean_Value_Arg {
            bool
          }
        }
      }
      Transaction {
        Cost
        From
        Hash
        Time
        GasPrice
      }
    }
  }
