Smart Contract Creation

Smart contract creators can use these queries to track the deployment of their own smart contracts and to monitor the deployment of new smart contracts by others.

Subscription to track new smart contract creation in real-time​

This subscription will return information on each new smart contract created on Ethereum. You can create a websocket to monitor the same in real-time.

subscription {
  eth_creates: EVM(network: eth) {
    creates: Calls(
      where: {
        Call: { Create: true }}) {
      Block {
        Time
      }
      Transaction{
        Hash
        From
      }
      Call {
        Input
        To
        Output
      }

    }
  }
}

This subscription has information on

  • The block time in which the smart contract was created
  • The transaction hash that created the smart contract
  • The address of the sender of the transaction that created the smart contract
  • The address of the newly created smart contract
  • The input data for the transaction that created the smart contract
  • The output data from the transaction that created the smart contract

Track new smart contract creation since a specific date​

This query below, will return the number of new smart contracts created on the Ethereum and Binance Smart Chain networks since a particular date. It will also return the date of each day on which new smart contracts were created. You can find the query here

query {
  eth_creates: EVM(dataset: archive network: eth) {
    creates: Calls(
      where: {
        Block: {Date: {after: "2023-06-01"}}
        Call: { Create: true }}) {
      count
      Block {
        Date
      }
    }
  }
  bsc_creates: EVM(dataset: archive network: bsc) {
    creates: Calls(
      where: {
        Block: {Date: {after: "2023-06-01"}}
        Call: { Create: true }}) {
      count
      Block {
        Date
      }
    }
  }
}

Get Code of the Token Contract​

This query will return the most recent transaction that created the token contract. The Output field of the Call object in the transaction contains the encoded bytecode of the contract. Replace 0xc923D39fA2d97fb4B660Fc66DAdB1421605975E0 with the token contract address that you want to get the code for. You can find the query here

{
  eth_creates: EVM(dataset: archive, network: eth) {
    creates: Calls(
      where: {Call: {Create: true, To: {is: "0xc923D39fA2d97fb4B660Fc66DAdB1421605975E0"}}}
      limit: {count: 1}
      orderBy: {descending: Block_Time}
    ) {
      Block {
        Time
      }
      Transaction {
        Hash
        From
        To
      }
      Call {
        Output
      }
    }
  }
}

Creator/Deployer of a smart contract​

You can use calls api to get smart contract creator or deployer of a smart contract. In the following example, where we getting deployer of deployer of 0xcd80c916b1194beb48abf007d0b79a7238436d56.

Try this query here.

{
  EVM(dataset: combined) {
    Calls(
      where: {Call: {Create: true}, Receipt: {ContractAddress: {is: "0xcd80c916b1194beb48abf007d0b79a7238436d56"}}}
    ) {
      Transaction {
        Hash
        From
        To
      }
      Block {
        Time
        Number
      }
    }
  }
}
