getBlock | Solana

​

Parameters

1. slot (u64, required) — the slot number to retrieve the block for.
2. config (object, optional) — configuration object containing:
   • commitment (string) — confirmed or finalized. Note: processed is not supported by this method.
   • encoding (string) — encoding for transaction data. Values:
     • json — parsed JSON with transaction message and meta (default).
     • jsonParsed — attempts to decode known program instructions into human-readable JSON. Falls back to standard JSON for unrecognized programs.
     • base64 — raw transaction bytes as base64.
     • base58 — raw transaction bytes as base58 (slow).
   • transactionDetails (string) — level of transaction detail:
     • full — returns complete transaction objects (default).
     • accounts — returns only account keys with signer, writable, and source annotations plus a restricted meta (only fee, err, preBalances, postBalances, preTokenBalances, postTokenBalances, rewards).
     • signatures — returns only the signatures array (no transactions field). Lightest option.
     • none — omits both transactions and signatures.
   • maxSupportedTransactionVersion (integer) — set to 0 to include versioned (v0) transactions in the response. Omitting this field causes an error if the block contains any v0 transactions.
   • rewards (boolean) — include block rewards. Default: true.

​

Response

• blockHeight (u64, nullable) — the actual block number produced in this slot.
• blockTime (i64, nullable) — estimated Unix timestamp of the block, as agreed upon by cluster validators.
• blockhash (string) — the hash of this block.
• parentSlot (u64) — the slot of the block’s parent.
• previousBlockhash (string) — the hash of the parent block.
• transactions — an array of transaction objects (when transactionDetails is full or accounts). Each object contains:
  • transaction — the transaction data in the requested encoding.
  • meta — transaction metadata including:
    • err — error if the transaction failed, null on success.
    • fee (u64) — fee charged for the transaction.
    • preBalances / postBalances — arrays of lamport balances before and after.
    • preTokenBalances / postTokenBalances — token balance changes.
    • logMessages — array of log strings produced by the transaction.
    • innerInstructions — inner instructions invoked via CPI.
    • loadedAddresses — addresses loaded from address lookup tables (writable and readonly arrays).
    • computeUnitsConsumed (u64) — compute units used.
    • returnData — data returned via sol_set_return_data, if any.
  • version — "legacy" or 0 for versioned transactions.
• signatures — an array of signature strings (only present when transactionDetails is signatures).
• rewards — an array of reward objects, each containing: pubkey, lamports, postBalance, rewardType (fee, rent, voting, staking), and commission (for voting/staking rewards).
