Accessing a network

By default any query is run on Ethereum Mainnet.

GraphQL

GraphQL queries are run on Ethereum Mainnet by default, and have a network parameter on root queries.

{
  transactions(network: SEPOLIA) {
    transactions {
      blockNumber
      from {
        address
      }
      to {
        address
      }
      value
      input
    }
  }
}

SQL

SQL tables are seperate, and can be found in the documentation panel on the left of the dashboard.

SELECT * FROM sepolia__erc721_transfer LIMIT 100
