Contract

A utility endpoint that helps identify which application/protocol a smart contract belongs to on a given network.

contract

Takes a contract address and network as input and returns information about any associated application or protocol. This is particularly useful when you have a contract address and need to determine which protocol it belongs to.

Example Use Case: Protocol Identification

When you encounter a contract address in a transaction or elsewhere, you can use this endpoint to identify which protocol that contract is associated with. For example, you could use this to:

• Identify which DEX a router contract belongs to
• Determine which protocol a lending pool, or LP token belongs to

Example Variables

{
  "address": "0x4bbfd120d9f352a0bed7a014bd67913a2007a878",
  "network": "BASE_MAINNET"
}

Example Query

query ($address: String!, $network: Network!) {
  contract(address: $address, network: $network) {
    address
    network
    app {
      databaseId
      displayName
      url
      slug
      imgUrl
      category {
        name
        slug
      }
    }
  }
}

Example Response

{
  "data": {
    "contract": {
      "address": "0x794a61358d6845594f94dc1db02a252b5b4814ad",
