eth_getTransactionByHash

In this section we will discuss how we can build eth_getTransactionByHash alternatives using Bitquery APIs.

Get Transaction Hash

We will use this stream to get the latest transactions hash. We will use this transaction hash as an input for the eth_getTransactionByHash alternative API.

subscription {
  EVM {
    Transactions {
      Transaction {
        Hash
      }
    }
  }
}

Get Transaction Details by Hash

This API serves as an alternative to the eth_getTransactionByHash JSON RPC method with Hash as 0xcc9ce436a02e8a4b44546affebe036fdd54b70c27ea3c2df18c0a1ed78ec9fbe.

query getTransactionByHash {
  EVM {
    Transactions(
      where: {Transaction: {Hash: {is: "0xcc9ce436a02e8a4b44546affebe036fdd54b70c27ea3c2df18c0a1ed78ec9fbe"}}}
    ) {
      Block {
        Time
        Number
      }
      ChainId
      Signature {
        R
        S
        V
      }
      Transaction {
        From
        Gas
        GasPrice
        Hash
        Index
        Nonce
        Cost
        Data
        To
        Value
        AccessList {
          Address
          StorageKeys
        }
        GasFeeCap
        Type
      }
      TransactionStatus {
        Success
      }
    }
  }
}

After running the above query this is the expected result.
