Solana

Solana


Solana API is available on Web3 API platform (opens in a new tab).

Solana is a decentralized blockchain built to enable scalable, user-friendly apps for the world.

In order for your Web3 application to interact with the Arbitrum blockchain — either by reading blockchain data or sending transactions to the network — it must connect to a Solana 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, lightweight 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 many various message-passing environments. It uses JSON (RFC 4627) as data format.

Methods


Deprecated


  • getConfirmedBlock — Returns identity and transaction information about a confirmed block in the ledger.
  • getConfirmedBlocks — Returns a list of confirmed blocks between two slots.
  • getConfirmedBlocksWithLimit — Returns a list of confirmed blocks starting at the given slot.
  • getConfirmedSignaturesForAddress2 — Returns signatures for confirmed transactions that include the given address in their accountKeys list.
  • getConfirmedTransaction — Returns transaction details for a confirmed transaction.
  • getFeeCalculatorForBlockhash — Returns the fee calculator associated with the query blockhash, or null if the blockhash has expired.
  • getFeeRateGovernor — Returns the fee rate governor information from the root bank.
  • getFees — Returns a recent block hash from the ledger, a fee schedule that can be used to compute the cost of submitting a transaction using it, and the last slot in which the blockhash will be valid.
  • getRecentBlockhash — Returns a recent block hash from the ledger, and a fee schedule that can be used to compute the cost of submitting a transaction using it.
  • getSnapshotSlot — Returns the highest slot that the node has a snapshot for.

getAccountInfo

Returns all information associated with the account of provided Pubkey.

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):

    • <string>: pubkey of account to query, as base-58 encoded string.
    • <object> (optional): configuration object containing the following fields:
      • commitment (string): the commitment describes how finalized a block is at that point in time. When querying the ledger state, it's recommended to use lower levels of commitment to report progress and higher levels to ensure the state will not be rolled back. For processing many dependent transactions in series, it's recommended to use "confirmed" commitment, which balances speed with rollback safety. For total safety, it's recommended to use "finalized" commitment:
        • finalized: the node will query the most recent block confirmed by supermajority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
        • confirmed: the node will query the most recent block that has been voted on by supermajority of the cluster.
          • it incorporates votes from gossip and replay.
          • it does not count votes on descendants of a block, only direct votes on that block.
          • this confirmation level also upholds "optimistic confirmation" guarantees in release 1.3 and onwards.
        • processed: the node will query its most recent block. Note that the block may still be skipped by the cluster.
      • encoding (string): encoding for Account data, either "base58" (slow), "base64", "base64+zstd", or "jsonParsed". "base58" is limited to Account data of less than 129 bytes. "base64" will return base64 encoded data for Account data of any size. "base64+zstd" compresses the Account data using Zstandard (opens in a new tab) and base64-encodes the result. "jsonParsed" encoding (opens in a new tab) attempts to use program-specific state parsers to return more human-readable and explicit account state data. If "jsonParsed" is requested but a parser cannot be found, the field falls back to "base64" encoding, detectable when the data field is type string.
      • dataSlice (object): limit the returned account data using the provided offset: <usize> and length: <usize> fields; only available for "base58", "base64" or "base64+zstd" encodings.
      • minContextSlot (number): sets the minimum slot that the request can be evaluated at.

Returns


  • <null>: if the requested account doesn't exist.
  • <object>: otherwise a JSON object containing:
    • lamports (u64): number of lamports assigned to this account, as a u64.
    • owner (string): base-58 encoded Pubkey of the program this account has been assigned to.
    • data ([string, encoding]|object): data associated with the account, either as encoded binary data or JSON format {<program>: <state>}, depending on the encoding parameter.
    • executable (boolean): boolean indicating if the account contains a program (and is strictly read-only).
    • rentEpoch (u64): the epoch at which this account will next owe rent, as u64.

getBlock

Returns identity and transaction information about a confirmed block in the ledger.

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):

    • <u64>: slot, as a u64 integer.
    • <object> (optional): configuration object containing the following optional fields:
      • encoding (string): encoding for each returned Transaction, either "json", "jsonParsed", "base58" (slow), "base64". If parameter not provided, the default encoding is "json". "jsonParsed" encoding (opens in a new tab) attempts to use program-specific instruction parsers to return more human-readable and explicit data in the transaction.message.instructions list. If "jsonParsed" is requested but a parser cannot be found, the instruction falls back to regular JSON encoding (accounts, data, and programIdIndex fields).
      • transactionDetails (string): level of transaction detail to return, either "full", "accounts", "signatures", or "none". If parameter not provided, the default detail level is "full". If "accounts" are requested, transaction details only include signatures and an annotated list of accounts in each transaction. Transaction metadata is limited to only: fee, err, pre_balances, post_balances, pre_token_balances, and post_token_balances.
      • rewards (boolean): whether to populate the rewards array. If parameter not provided, the default includes rewards.
      • commitment (string; default: "finalized"): the commitment describes how finalized a block is at that point in time. When querying the ledger state, it's recommended to use lower levels of commitment to report progress and higher levels to ensure the state will not be rolled back. For processing many dependent transactions in series, it's recommended to use "confirmed" commitment, which balances speed with rollback safety. For total safety, it's recommended to use "finalized" commitment:
        • finalized: the node will query the most recent block confirmed by supermajority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
        • confirmed: the node will query the most recent block that has been voted on by supermajority of the cluster.
          • it incorporates votes from gossip and replay.
          • it does not count votes on descendants of a block, only direct votes on that block.
          • this confirmation level also upholds "optimistic confirmation" guarantees in release 1.3 and onwards.
      • maxSupportedTransactionVersion (number): sets the max transaction version to return in responses. If the requested block contains a transaction with a higher version, an error will be returned. If this parameter is omitted, only legacy transactions will be returned, and a block containing any versioned transaction will prompt the error.

When querying the ledger state, it's recommended to use lower levels of commitment to report progress and higher levels to ensure the state will not be rolled back. For processing many dependent transactions in series, it's recommended to use "confirmed" commitment, which balances speed with rollback safety. For total safety, it's recommended to use "finalized" commitment:
        • finalized: the node will query the most recent block confirmed by supermajority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
        • confirmed: the node will query the most recent block that has been voted on by supermajority of the cluster.
          • it incorporates votes from gossip and replay.
          • it does not count votes on descendants of a block, only direct votes on that block.
          • this confirmation level also upholds "optimistic confirmation" guarantees in release 1.3 and onwards.
        • processed: the node will query its most recent block. Note that the block may still be skipped by the cluster.
      • minContextSlot (number): sets the minimum slot that the request can be evaluated at.

Returns


  • <u64>: a current block height.
