Solana RPC

Shakudo provides shared and dedicated RPC nodes. We support all the official Solana RPC HTTPS and WSS methods as well as some customly built methods.

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 https://your-endpoint.hyperplane.dev -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.

HTTP request RPC methods​

getAccountInfo​

Use getAccountInfo to get all information associated with the account of provided Pubkey

Parameters:​

  • <string> - Pubkey of account to query, as base-58 encoded string
  • <object> - (optional) Configuration object containing the following fields:
    • (optional) commitment: <string> - Commitment
    • (optional) 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 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>.
    • (optional) 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.
    • (optional) minContextSlot: <number> - set the minimum slot that the request can be evaluated at.

Results:​

The result will be an RpcResponse JSON object with value equal to:

  • <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 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

    • (optional) encoding: <string> - encoding for each returned Transaction, either "json", "jsonParsed", "base58" (slow), "base64". If parameter not provided, the default encoding is "json". "jsonParsed" encoding 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).
    • (optional) transactionDetails: <string> - level of transaction detail to return, either "full", "signatures", or "none". If parameter not provided, the default detail level is "full".

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.account_keys. 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.account_keys.
      • 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] or 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 or undefined> - Pubkey of token balance's owner.
  • programId: <string or 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 or null> - Token amount as a float, accounting for decimals. DEPRECATED
    • uiAmountString: <string> - Token amount as a string, accounting for decimals.

getTokenAccountsByDelegate​

Returns all SPL Token accounts by approved Delegate.

Parameters:​

  • <string> - Pubkey of account delegate to query, as base-58 encoded string
  • <object> - Either:
    • mint: <string> - Pubkey of the specific token Mint to limit accounts to, as base-58 encoded string; or

  • <object> - (optional) Configuration object containing the following fields:
    • (optional) commitment: <string> - Commitment
    • (optional) 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 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>.
    • (optional) 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.
    • (optional) minContextSlot: <number> - set the minimum slot that the request can be evaluated at.

Results:​

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

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> - fully-signed Transaction, as encoded string
  • <object> - (optional) Configuration object containing the following field:
    • skipPreflight: <bool> - if true, skip the preflight transaction checks (default: false)
    • preflightCommitment: <string> - (optional) Commitment level to use for preflight (default: "finalized").
    • encoding: <string> - (optional) Encoding used for the transaction data. Either "base58" (slow, DEPRECATED), or "base64". (default: "base58").
    • maxRetries: <usize> - (optional) 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.
    • (optional) minContextSlot: <number> - set the minimum slot at which to perform preflight transaction checks.

Results:​

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

Example:​

simulateTransaction​

Simulate sending a transaction

Parameters:​

  • <string> - Transaction, as an encoded string. The transaction must have a valid blockhash, but is not required to be signed.
  • <object> - (optional) Configuration object containing the following fields:
    • sigVerify: <bool> - if true the transaction signatures will be verified (default: false, conflicts with replaceRecentBlockhash)
    • commitment: <string> - (optional) Commitment level to simulate the transaction at (default: "finalized").
    • encoding: <string> - (optional) Encoding used for the transaction data. Either "base58" (slow, DEPRECATED), or "base64". (default: "base58").
    • replaceRecentBlockhash: <bool> - (optional) if true the transaction recent blockhash will be replaced with the most recent blockhash. (default: false, conflicts with sigVerify)

Subscription Websocket​

After connecting to the RPC PubSub websocket at ws://<ADDRESS>/:

  • Submit subscription requests to the websocket using the methods below
  • Multiple subscriptions may be active at once
  • Many subscriptions take the optional commitment parameter, defining how finalized a change should be to trigger a notification. For subscriptions, if commitment is unspecified, the default value is "finalized".

"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>. Default is "base64".
    • (optional) transactionDetails: <string> - level of transaction detail to return, either "full", "signatures", or "none". If parameter not provided, the default detail level is "full".
    • (optional) showRewards: bool - whether to populate the rewards array. If parameter not provided, the default includes rewards.

Results:​

  • integer - subscription id (needed to unsubscribe)

programSubscribe​

Subscribe to a program to receive notifications when the lamports or data for a given account owned by the program changes

Parameters:​

  • <string> - program_id Pubkey, as base-58 encoded string
  • <object> - (optional) Configuration object containing the following optional fields:
    • (optional) Commitment
    • encoding: <string> - encoding for Account data, either "base58" (slow), "base64", "base64+zstd" or "jsonParsed". "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>.
    • (optional) filters: <array> - filter results using various filter objects; account must meet all filter criteria to be included in results

Results:​

  • <integer> - Subscription id (needed to unsubscribe)

Example:​

Request:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "programSubscribe",
  "params": [
    "11111111111111111111111111111111",

    • (optional) encoding: <string> - encoding for each returned Transaction, either "json", "jsonParsed", "base58" (slow), "base64". If parameter not provided, the default encoding is "json". "jsonParsed" encoding 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).

getConfirmedSignaturesForAddress2​

DEPRECATED: Please use getSignaturesForAddress instead This method is expected to be removed in solana-core v2.0

Returns signatures for confirmed transactions that include the given address in their accountKeys list. Returns signatures backwards in time from the provided signature or most recent confirmed block

Parameters:​

  • <string> - account address as base-58 encoded string
  • <object> - (optional) Configuration object containing the following fields:
    • limit: <number> - (optional) maximum transaction signatures to return (between 1 and 1,000, default: 1,000).
    • before: <string> - (optional) start searching backwards from this transaction signature. If not provided the search starts from the top of the highest max confirmed block.
    • until: <string> - (optional) search until this transaction signature, if found before limit reached.
    • (optional) Commitment; "processed" is not supported. If parameter not provided, the default is "finalized".

Results:​

The result field will be an array of transaction signature information, ordered from newest to oldest transaction:

  • <object>
    • signature: <string> - transaction signature as base-58 encoded string
    • slot: <u64> - The slot that contains the block with the transaction
    • err: <object | null> - Error if transaction failed, null if transaction succeeded. TransactionError definitions
    • memo: <string |null> - Memo associated with the transaction, null if no memo is present
    • blockTime: <i64 | null> - estimated production time, as Unix timestamp (seconds since the Unix epoch) of when transaction was processed. null if not available.

getConfirmedTransaction​

DEPRECATED: Please use getTransaction instead This method is expected to be removed in solana-core v2.0

Returns transaction details for a confirmed transaction

Parameters:​

  • <string> - transaction signature as base-58 encoded string
  • <object> - (optional) Configuration object containing the following optional fields:
    • (optional) encoding: <string> - encoding for each returned Transaction, either "json", "jsonParsed", "base58" (slow), "base64". If parameter not provided, the default encoding is "json". "jsonParsed" encoding 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).
    • (optional) Commitment; "processed" is not supported. If parameter not provided, the default is "finalized".

Results:​

  • <null> - if transaction is not found or not confirmed
  • <object> - if transaction is confirmed, an object with the following fields:
    • slot: <u64> - the slot this transaction was processed in
    • transaction: <object|[string,encoding]> - Transaction object, either in JSON format or encoded binary data, depending on encoding parameter
    • blockTime: <i64 | null> - estimated production time, as Unix timestamp (seconds since the Unix epoch) of when the transaction was processed. null if not available
    • meta: <object | null> - transaction status metadata object:
      • err: <object | null> - Error if transaction failed, null if transaction succeeded. TransactionError definitions
      • fee: <u64> - fee this transaction was charged, as u64 integer
      • preBalances: <array> - array of u64 account balances from before the transaction was processed
      • postBalances: <array> - array of u64 account balances after the transaction was processed
      • innerInstructions: <array|null> - List of inner instructions or null if inner instruction recording was not enabled during this transaction
      • preTokenBalances: <array|undefined> - List of token balances from before the transaction was processed or omitted if token balance recording was not yet enabled during this transaction
      • postTokenBalances: <array|undefined> - List of token balances from after the transaction was processed or omitted if token balance recording was not yet enabled during this transaction
      • logMessages: <array|null> - array of string log messages or null if log message recording was not enabled during this transaction
