getParsedBlock

​

Parameters

• slot_number string. The slot number encoded as u64, 64-bit unsigned integer.
• object optional. Configuration object containing the following fields:
  • commitment string. The level of commitment required for the query. The options include:
    • finalized string.
      • The node will query the most recent block confirmed by the supermajority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
    • confirmed string.
      • The node will query the most recent block that has been voted on by the supermajority of the cluster.
    • processed string.
      • The node will query its most recent block. Note that the block may not be complete.
• encoding string. (default: json) The encoding format for account data. It can be one of base58 (slow), base64, base64+zstd or jsonParsed.
• transactionDetails string (default: full). It specifies the level of transaction details to include in the response. The possible values are full, signatures, and none.
• rewards boolean (default: true) It determines whether to populate the rewards array or not.
• maxSupportedTransactionVersion boolean. The maximum 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 an error.
• legacy boolean. The older transaction format with no additional benefit.
• 0 boolean. The additional support for Address Lookup Tables.

​

Returns

• blockhash. The hash of the block encoded as base-58 string.
• previousBlockhash. The blockhash of this block’s parent encoded as base-58 string.
• parentSlot. The slot number of this block’s parent.
• transactions. An array of transaction objects within the block. Each transaction object contains the following fields:
  • meta. The transaction status metadata object with the following fields:
    • err. Error code if the transaction failed or null if the transaction succeeds.
    • fee. The total fees paid by all transactions in the block encoded as u64 integer.
    • innerInstructions. The list of inner instructions and it’s omitted or null if inner instruction recording was not yet enabled during the transaction.
    • loadedAddresses The list of loaded addresses objects.
      • readonly The ordered list of base-58 encoded addresses for readonly loaded accounts.
      • writable The ordered list of base-58 encoded addresses for writable loaded accounts.
    • logMessages. An array of string log messages. Omitted or null if log message recording was not yet enabled during the transaction
    • postBalances. An array of lamport balances for each account in the block after the transactions were processed.
    • postTokenBalances. The list of token balances from after the transaction was processed and it’s omitted if inner instruction recording was not yet enabled during the transaction
    • preBalances. An array of lamport balances for each account in the block before the transactions were processed.
    • preTokenBalances. The list of token balances from before the transaction was processed and it’s omitted if inner instruction recording was not yet enabled during the transaction
    • rewards. An array of reward objects detailing the rewards for this block. It is only present if rewards are requested; an array of JSON objects with the following fields:
      • pubkey. The public key of the account that received the award encoded as base-58 string.
      • lamports. The number of reward lamports credited or debited by the account.
      • postBalance. The account balance in lamports after the reward was applied.
      • rewardType. The type of reward. It could be fee, rent, voting, staking.
      • commission. The vote account commission when the reward was credited, only present for voting and staking rewards.
    • status. The status of the transaction. It returns Ok if the transaction was successful and Err if the transaction failed with TransactionError.
  • transaction. The transaction object with the following fields:
    • message. The transaction message containing the following fields:
      • accountKeys. An array of public keys involved in the transaction.
      • header An object containing the transaction’s header, including the following fields:
        • numRequiredSignatures The number of required signatures for the transaction.
        • numReadonlySignedAccounts The number of readonly accounts that have signed the transaction.
        • numReadonlyUnsignedAccounts The number of readonly accounts that have not signed the transaction.
      • instructions. An array of instruction objects for the transaction with the following fields:
        • accounts An array of integers representing the indices of accounts involved in the instruction.
        • data The instruction data encoded in the specified format.
        • programIdIndex The index of the program ID in the accountKeys.
    • recentBlockhash. The most recent blockhash used for the transaction
    • signatures. An array of signatures strings corresponding to the transaction order in the block.
