API Reference
Scroll

Scroll

Scroll API is available on RPC Service (opens in a new tab).

Scroll is a zkEVM-based zkRollup on Ethereum that enables native compatibility for existing Ethereum applications and tools.

In order for your Web3 application to interact with Scroll — either by reading blockchain data or sending transactions to the network — it must connect to a Scroll node. Developers interact with the blockchain using the methods provided by the API.

The API interaction follows the JSON-RPC (opens in a new tab) which is a stateless, light-weight remote procedure call (RPC) protocol. It defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in other message-passing environments. It uses JSON (RFC 4627) as data format.

      • from (string; data, 20 bytes; optional): the address the transaction is sent from.
      • to (string; data, 20 bytes; optional): the address the transaction is directed to.
      • gas (string; quantity; optional): the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
      • gasPrice (string; quantity; optional): the gas price willing to be paid by the sender in wei.
      • value (string; quantity; optional): the value sent with this transaction, in wei.
      • data (string; data; optional): the hash of the method signature and encoded parameters.
    2. <string> (quantity|tag; optional): either a HEX value of a block number or one of the following block tags:

      • earliest: the lowest numbered block available on the client.
      • finalized: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
      • safe: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
      • latest: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
      • pending: a sample next block built by the client on top of the latest and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

Returns

  • <string> (quantity): the amount of gas used.

Returns information on a transaction by block number and transaction index position.

Parameters

  • id (integer; required): a request ID (example: 1).

  • jsonrpc (string; required): a JSON RPC spec used (example: 2.0).

  • method (string; required): a method used for the request.

  • params (array; required):

    1. <string> (quantity|tag): either the hex value of a block number or one of the following block tags:
      • earliest: the lowest numbered block available on the client.
      • finalized: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
      • safe: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
      • latest: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
      • pending: a sample next block built by the client on top of the latest and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

  • nonce (string; quantity): the number of transactions made by the sender prior to this one.
  • to (string: data, 20 bytes): an address of the receiver: null when it's a contract creation transaction.
  • transactionIndex (string; quantity): the transaction index position in the block; null when it's pending.
  • value (string; quantity): the value transferred in wei.

    1. object: the filter options:

      • fromBlock (string; quantity|tag; optional; default: "latest"): either the block number or one of the following block tags:

        • latest: for the last mined block.
        • earliest: for the lowest numbered block available on the client.
        • pending: for not yet mined transactions.
      • toBlock (string; quantity|tag; optional; default: "latest"): either the block number or one of the following block tags:

        • latest: for the last mined block.
        • earliest: for the lowest numbered block available on the client.
        • pending: for not yet mined transactions.
      • address (array of strings; data, 20 bytes; optional): a contract address or a list of addresses from which logs should originate.

      • topics (array of strings; data; optional): an array of 32 bytes data topics. Topics are order-dependent. Each topic can also be an array of data with "or" options.

      • blockhash (string; data, 32 bytes; optional; future): with the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in the filter criteria, then neither fromBlock nor toBlock are allowed.

Returns

  • removed (string; tag): true when the log was removed, due to a chain reorganization; false if it's a valid log.
  • logIndex (string; quantity): the log index position in the block; null when it's a pending log.
  • transactionIndex (string; quantity): the transactions index position log was created from; null when it's a pending log.
  • transactionHash (string; data, 32 bytes): a hash of the transactions this log was created from; null when it's a pending log.
  • blockHash (string; data, 32 bytes): a hash of the block containing the log; null when it's pending; null when it's a pending log.
  • blockNumber (string; quantity): the number of the block containing the log; null when it's pending; null when it's a pending log.
  • address (string; data, 20 bytes): an address from which this log originated.
  • data (string; data): contains one or more 32 bytes non-indexed arguments of the log.
  • topics (array of strings; data): an array of 0 to 4 32 bytes data of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)
