Node API - Arbitrum


API AuthenticationClick to view API Authentication details
API calls require authentication with API key via Authorization request header or URL property. Calls are made to one of the Arbitrum Node API endpoints found in your app's dashboard.

For example: https://arbitrum-mainnet-rpc-archive.datahub.figment.io

Here's some boilerplate to get you started. 
fetch("https://arbitrum-mainnet-rpc-archive.datahub.figment.io", {
    method: 'POST', // can also be 'GET', 'PUT' or any appropriate method
    headers: {
        "Authorization" : "<api_key>",
        "Content-Type": "application/json" // if method is 'POST'
    },
    body: JSON.stringify({
      // JSON Payload
    })
})

eth_chainId

Returns the chain ID of the current network.

Request Body (try it)
Example Response
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0xa4b1"
}

Parameters

None

Response

  • QUANTITY — Integer of the current block number the client is on.

eth_call

Executes a new message call immediately without creating a transaction on the block chain.

Request Body (try it)
Example Response
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x"
}
SpecificationView Specification

Parameters

  • Object — The transaction call object
  • from — DATA 20 Bytes, The address the transaction is sent from (optional).
  • to — DATA 20 Bytes, The address the transaction is directed to.
  • gas — QUANTITY Integer of the gas provided for the transaction execution (optional). eth_call consumes zero gas, but this parameter may be needed by some executions.
  • gasPrice — QUANTITY Integer of the gasPrice used for each paid gas (optional).
  • value — QUANTITY Integer of the value sent with this transaction (optional).
  • data — DATA Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation
  • QUANTITY|TAG — Integer block number, or the string "latest", "earliest" or "pending", see the default block parameter

Response

  • DATA — The return value of the executed contract.

eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Parameters

See eth_call parameters, expect that all properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.

Response

  • QUANTITY — The amount of gas used.

eth_gasPrice

Returns the current price per gas in wei.

Parameters

None

Response

  • QUANTITY — Integer of the current gas price in wei.

eth_newFilter

Creates a filter object, based on filter options, to notify when the state changes (logs).

Example Response
{
  "jsonrpc": "2.0",
  "id": 1,

}
SpecificationView Specification

To check if the state has changed, call eth_getFilterChanges. A note on specifying topic filters: Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:

  • [] "anything"
  • [A] "A in first position (and anything after)"
  • [null, B] "anything in first position AND B in second position (and anything after)"
  • [A, B] "A in first position AND B in second position (and anything after)"
  • [[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"

Parameters

  • Object — The filter options:
  • fromBlock — QUANTITY|TAG (default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions (optional).
  • toBlock — QUANTITY|TAG (default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions (optional).
  • address — DATA|Array 20 Bytes, Contract address or a list of addresses from which logs should originate (optional).
  • topics: Array of DATA Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options (optional).

Response

  • QUANTITY — A filter id.

Parameters

  • Object — The filter options:
  • fromBlock — QUANTITY|TAG (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
  • toBlock — QUANTITY|TAG (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
  • address — DATA|Array 20 Bytes (optional) Contract address or a list of addresses from which logs should originate.
  • topics — Array of DATA (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options.
  • blockhash — 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 in the filter criteria, then neither fromBlock nor toBlock are allowed.

Response

Array — Array of log objects, or an empty array if nothing has changed since last poll.

  • For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x3454645634534..."].
  • For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].
  • For filters created with eth_newFilter logs are objects with following params:
    • removed — TAG true When the log was removed, due to a chain reorganization. false if its a valid log.
    • logIndex — QUANTITY Integer of the log index position in the block. null when its pending log.
    • transactionIndex — QUANTITY Integer of the transactions index position log was created from. null when its pending log.
    • transactionHash — DATA 32 Bytes, Hash of the transactions this log was created from. null when its pending log.
    • blockHash — DATA 32 Bytes, Hash of the block where this log was in. null when its pending. null when its pending log.
    • blockNumber — QUANTITY The block number where this log was in. null when its pending. null when its pending log.
    • address — DATA 20 Bytes, Address from which this log originated.
    • data — DATA Contains one or more 32 Bytes non-indexed arguments of the log.
    • topics — Array of DATA 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.)
