JSON RPC HTTP Methods

Solana nodes accept HTTP requests using the JSON-RPC 2.0 specification.

к сведению

For JavaScript applications, use the @solana/web3.js library as a convenient interface for the RPC methods to interact with a Solana node.

For an PubSub connection to a Solana node, use the Websocket API.

RPC HTTP Endpoint​

Default port: 8899 e.g. http://localhost:8899, http://192.168.1.88:8899

Request Formatting​

To make a JSON-RPC request, send an HTTP POST request with a Content-Type: application/json header. The JSON request data should contain 4 fields:

  • jsonrpc: <string> - set to "2.0"
  • id: <number> - a unique client-generated identifying integer
  • method: <string> - a string containing the method to be invoked
  • params: <array> - a JSON array of ordered parameter values

Example using curl:

curl http://localhost:8899 -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getBalance",
    "params": [
      "83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri"
    ]
  }
'

The response output will be a JSON object with the following fields:

  • jsonrpc: <string> - matching the request specification
  • id: <number> - matching the request identifier
  • result: <array|number|object|string> - requested data or success confirmation

Requests can be sent in batches by sending an array of JSON-RPC request objects as the data for a single POST.

Definitions​

  • Hash: A SHA-256 hash of a chunk of data.
  • Pubkey: The public key of a Ed25519 key-pair.
  • Transaction: A list of Solana instructions signed by a client keypair to authorize those actions.
  • Signature: An Ed25519 signature of transaction's payload data including instructions. This can be used to identify transactions.

Configuring State Commitment​

For preflight checks and transaction processing, Solana nodes choose which bank state to query based on a commitment requirement set by the client. 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.

In descending order of commitment (most finalized to least finalized), clients may specify:

  • "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.

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.

Example​

The commitment parameter should be included as the last element in the params array:

curl http://localhost:8899 -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getBalance",
    "params": [
      "83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri",
      {
        "commitment": "finalized"
      }
    ]
  }
'

Default:​

If commitment configuration is not provided, the node will default to "finalized" commitment

Only methods that query bank state accept the commitment parameter. They are indicated in the API Reference below.

RpcResponse Structure​

Many methods that take a commitment parameter return an RpcResponse JSON object comprised of two parts:

  • context : An RpcResponseContext JSON structure including a slot field at which the operation was evaluated.
  • value : The value returned by the operation itself.

Parsed Responses​

Some methods support an encoding parameter, and can return account or instruction data in parsed JSON format if "encoding":"jsonParsed" is requested and the node has a parser for the owning program. Solana nodes currently support JSON parsing for the following native and SPL programs:

ProgramAccount StateInstructions
Address Lookupv1.15.0v1.15.0
BPF Loadern/astable
BPF Upgradeable Loaderstablestable
Configstable
SPL Associated Token Accountn/astable
SPL Memon/astable
SPL Tokenstablestable
SPL Token 2022stablestable
Stakestablestable
Votestablestable

The list of account parsers can be found here, and instruction parsers here.

Filter criteria​

Some methods support providing a filters object to enable pre-filtering the data returned within the RpcResponse JSON object. The following filters exist:

  • memcmp: object - compares a provided series of bytes with program account data at a particular offset. Fields:

    • offset: usize - offset into program account data to start comparison
    • bytes: string - data to match, as encoded string
    • encoding: string - encoding for filter bytes data, either "base58" or "base64". Data is limited in size to 128 or fewer decoded bytes.
      NEW: This field, and base64 support generally, is only available in solana-core v1.14.0 or newer. Please omit when querying nodes on earlier versions

  • dataSize: u64 - compares the program account data length with the provided data size

Health Check​

Although not a JSON RPC API, a GET /health at the RPC HTTP Endpoint provides a health-check mechanism for use by load balancers or other network infrastructure. This request will always return a HTTP 200 OK response with a body of "ok", "behind" or "unknown" based on the following conditions:

  1. If one or more --known-validator arguments are provided to solana-validator - "ok" is returned when the node has within HEALTH_CHECK_SLOT_DISTANCE slots of the highest known validator, otherwise "behind". "unknown" is returned when no slot information from known validators is not yet available.
  2. "ok" is always returned if no known validators are provided.

JSON RPC API Reference​

getAccountInfo​

Returns all information associated with the account of provided Pubkey

Parameters:​

string required

Pubkey of account to query, as base-58 encoded string

object optional

Configuration object containing the following fields:

commitment string optional

encoding string optional

Encoding format for Account data

Values: base58base64base64+zstdjsonParsed

Details
  • base58 is slow and limited to less than 129 bytes of Account data.
  • base64 will return base64 encoded data for Account data of any size.
  • base64+zstd compresses the Account data using Zstandard and base64-encodes the result.
  • jsonParsed encoding 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 optional

Request a slice of the account's data.
  • length: <usize> - number of bytes to return
  • offset: <usize> - byte offset from which to start reading
к сведению

Data slicing is only available for base58, base64, or base64+zstd encodings.

    Transaction Structure​

    Transactions are quite different from those on other blockchains. Be sure to review Anatomy of a Transaction to learn about transactions on Solana.

    The JSON structure of a transaction is defined as follows:

    • signatures: <array[string]> - A list of base-58 encoded signatures applied to the transaction. The list is always of length message.header.numRequiredSignatures and not empty. The signature at index i corresponds to the public key at index i in message.accountKeys. The first one is used as the transaction id.
    • message: <object> - Defines the content of the transaction.
      • accountKeys: <array[string]> - List of base-58 encoded public keys used by the transaction, including by the instructions and for signatures. The first message.header.numRequiredSignatures public keys must sign the transaction.
      • header: <object> - Details the account types and signatures required by the transaction.
        • numRequiredSignatures: <number> - The total number of signatures required to make the transaction valid. The signatures must match the first numRequiredSignatures of message.accountKeys.
        • numReadonlySignedAccounts: <number> - The last numReadonlySignedAccounts of the signed keys are read-only accounts. Programs may process multiple transactions that load read-only accounts within a single PoH entry, but are not permitted to credit or debit lamports or modify account data. Transactions targeting the same read-write account are evaluated sequentially.
        • numReadonlyUnsignedAccounts: <number> - The last numReadonlyUnsignedAccounts of the unsigned keys are read-only accounts.
      • recentBlockhash: <string> - A base-58 encoded hash of a recent block in the ledger used to prevent transaction duplication and to give transactions lifetimes.
      • instructions: <array[object]> - List of program instructions that will be executed in sequence and committed in one atomic transaction if all succeed.
        • programIdIndex: <number> - Index into the message.accountKeys array indicating the program account that executes this instruction.
        • accounts: <array[number]> - List of ordered indices into the message.accountKeys array indicating which accounts to pass to the program.
        • data: <string> - The program input data encoded in a base-58 string.
      • addressTableLookups: <array[object]|undefined> - List of address table lookups used by a transaction to dynamically load addresses from on-chain address lookup tables. Undefined if maxSupportedTransactionVersion is not set.
        • accountKey: <string> - base-58 encoded public key for an address lookup table account.
        • writableIndexes: <array[number]> - List of indices used to load addresses of writable accounts from a lookup table.
        • readonlyIndexes: <array[number]> - List of indices used to load addresses of readonly accounts from a lookup table.

    Inner Instructions Structure​

    The Solana runtime records the cross-program instructions that are invoked during transaction processing and makes these available for greater transparency of what was executed on-chain per transaction instruction. Invoked instructions are grouped by the originating transaction instruction and are listed in order of processing.

    The JSON structure of inner instructions is defined as a list of objects in the following structure:

    • index: number - Index of the transaction instruction from which the inner instruction(s) originated
    • instructions: <array[object]> - Ordered list of inner program instructions that were invoked during a single transaction instruction.
      • programIdIndex: <number> - Index into the message.accountKeys array indicating the program account that executes this instruction.
      • accounts: <array[number]> - List of ordered indices into the message.accountKeys array indicating which accounts to pass to the program.
      • data: <string> - The program input data encoded in a base-58 string.

    Token Balances Structure​

    The JSON structure of token balances is defined as a list of objects in the following structure:

    • accountIndex: <number> - Index of the account in which the token balance is provided for.
    • mint: <string> - Pubkey of the token's mint.
    • owner: <string|undefined> - Pubkey of token balance's owner.
    • programId: <string|undefined> - Pubkey of the Token program that owns the account.
    • uiTokenAmount: <object> -
      • amount: <string> - Raw amount of tokens as a string, ignoring decimals.
      • decimals: <number> - Number of decimals configured for token's mint.
      • uiAmount: <number|null> - Token amount as a float, accounting for decimals. DEPRECATED
      • uiAmountString: <string> - Token amount as a string, accounting for decimals.

    Pubkey of account delegate to query, as base-58 encoded string

    object optional

    A JSON object with one of the following fields:

    • mint: <string> - Pubkey of the specific token Mint to limit accounts to, as base-58 encoded string; or
    • programId: <string> - Pubkey of the Token program that owns the accounts, as base-58 encoded string

    object optional

    Configuration object containing the following fields:

    commitment string optional

    minContextSlot number optional

    The minimum slot that the request can be evaluated at

    dataSlice object optional

    Request a slice of the account's data.
    • length: <usize> - number of bytes to return
    • offset: <usize> - byte offset from which to start reading
    к сведению

    Data slicing is only available for base58, base64, or base64+zstd encodings.

    encoding string optional

    Encoding format for Account data

    Values: base58base64base64+zstdjsonParsed

    Details
    • base58 is slow and limited to less than 129 bytes of Account data.
    • base64 will return base64 encoded data for Account data of any size.
    • base64+zstd compresses the Account data using Zstandard and base64-encodes the result.
    • jsonParsed encoding 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.

    Result:​

    The result will be an RpcResponse JSON object with value equal to an array of JSON objects, which will contain:

    • pubkey: <string> - the account Pubkey as base-58 encoded string
    • account: <object> - a JSON object, with the following sub fields:
      • 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: <object> - Token state data associated with the account, either as encoded binary data or in JSON format {<program>: <state>}
      • executable: <bool> - 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
      • size: <u64> - the data size of the account

    When the data is requested with the jsonParsed encoding a format similar to that of the Token Balances Structure can be expected inside the structure, both for the tokenAmount and the delegatedAmount - with the latter being an optional object.

    sendTransaction​

    Submits a signed transaction to the cluster for processing.

    This method does not alter the transaction in any way; it relays the transaction created by clients to the node as-is.

    If the node's rpc service receives the transaction, this method immediately succeeds, without waiting for any confirmations. A successful response from this method does not guarantee the transaction is processed or confirmed by the cluster.

    While the rpc service will reasonably retry to submit it, the transaction could be rejected if transaction's recent_blockhash expires before it lands.

    Use getSignatureStatuses to ensure a transaction is processed and confirmed.

    Before submitting, the following preflight checks are performed:

    1. The transaction signatures are verified
    2. The transaction is simulated against the bank slot specified by the preflight commitment. On failure an error will be returned. Preflight checks may be disabled if desired. It is recommended to specify the same commitment and preflight commitment to avoid confusing behavior.

    The returned signature is the first signature in the transaction, which is used to identify the transaction (transaction id). This identifier can be easily extracted from the transaction data before submission.

    Parameters:​

    string required

    Fully-signed Transaction, as encoded string.

    object optional

    Configuration object containing the following optional fields:

    encoding string Default: base58

    Encoding used for the transaction data.

    Values: base58 (slow, DEPRECATED), or base64.

    skipPreflight bool Default: false

    if "true", skip the preflight transaction checks

    preflightCommitment string Default: finalized

    Commitment level to use for preflight.

    maxRetries usize

    Maximum number of times for the RPC node to retry sending the transaction to the leader. If this parameter not provided, the RPC node will retry the transaction until it is finalized or until the blockhash expires.

    minContextSlot number

    set the minimum slot at which to perform preflight transaction checks

    Result:​

    <string> - First Transaction Signature embedded in the transaction, as base-58 encoded string (transaction id)

    simulateTransaction​

    Simulate sending a transaction

    Parameters:​

    string required

    Transaction, as an encoded string.

    примечание

    The transaction must have a valid blockhash, but is not required to be signed.

    object optional

    Configuration object containing the following fields:

    commitment string optionalDefault: finalized

    Commitment level to simulate the transaction at

    sigVerify bool optional

    if `true` the transaction signatures will be verified (conflicts with `replaceRecentBlockhash`)

    replaceRecentBlockhash bool optional

    if `true` the transaction recent blockhash will be replaced with the most recent blockhash. (conflicts with `sigVerify`)

    minContextSlot number optional

    the minimum slot that the request can be evaluated at

    encoding string optionalDefault: base58

    Encoding used for the transaction data.

    Values: base58 (slow, DEPRECATED), or base64.

    encoding string Default: base64

    encoding for returned Account data

    Values: base64base58base64+zstdjsonParsed

    Details
    • jsonParsed encoding 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 binary encoding, detectable when the data field is type string.

    Result:​

    The result will be an RpcResponse JSON object with value set to a JSON object with the following fields:

    • err: <object|string|null> - Error if transaction failed, null if transaction succeeded. TransactionError definitions
    • logs: <array|null> - Array of log messages the transaction instructions output during execution, null if simulation failed before the transaction was able to execute (for example due to an invalid blockhash or signature verification failure)
    • accounts: <array|null> - array of accounts with the same length as the accounts.addresses array in the request
      • <null> - if the account doesn't exist or if err is not null
      • <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 encoding parameter
        • executable: <bool> - 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
    • unitsConsumed: <u64|undefined> - The number of compute budget units consumed during the processing of this transaction
    • returnData: <object|null> - the most-recent return data generated by an instruction in the transaction, with the following fields:
