Arguments API

Query Tron smart contract call and event arguments, including argument names, types, values, and associated blocks.

List Latest Tron Smart Contract Events and Call Arguments​

Fetch the most recent smart contract call and event arguments on Tron, including argument name, type, value, call depth, and block details.

Variations: Add a smartContractAddress filter to scope to a specific contract, or adjust limit for more results.

{
  tron {
    arguments(
      options: {desc: "block.timestamp.iso8601", limit: 10}
      date: {after: "2023-07-30"}
    ) {
      argument {
        name
        type
      }
      block {
        height
        timestamp {
          iso8601
        }
      }
      callDepth
      owner {
        address
      }
      txHash
      txIndex
      value {
        value
      }
    }
  }
}

Filter Tron Arguments by Transfer Event Name​

Retrieve only the arguments associated with Transfer events on Tron smart contracts.

Variations: Replace "Transfer" with any event name (e.g., "Approval"), or use the in operator to match multiple event names at once.

{
  tron {
    arguments(
      options: {desc: "block.timestamp.iso8601", limit: 10}
      date: {after: "2023-07-30"}
      smartContractEvent: {is: "Transfer"}
    ) {
      argument {
        name
        type
      }
      block {
        height
        timestamp {
          iso8601
        }
      }
      callDepth
      owner {
        address
      }
      txHash
      txIndex
      value {
        value
      }
    }
  }
}

Filter Tron Transfer Arguments After a Minimum Block Height​

Fetch Transfer event arguments that occurred after a specific Tron block height, useful for incremental data syncing.

Variations: Combine height with date filters for tighter time windows, or change the event name to track other contract events.

{
  tron {
    arguments(
      options: {desc: "block.timestamp.iso8601", limit: 10}
      date: {after: "2023-07-30"}
      smartContractEvent: {is: "Transfer"}
      height: {gt: 53392720}
    ) {
      argument {
        name
        type
      }
      block {
        height
        timestamp {
          iso8601
        }
      }
      callDepth
      owner {
        address
      }
      txHash
      txIndex
      value {
        value
      }
    }
  }
}
