The ots_getBlockTransactions JSON-RPC method retrieves paginated transactions for a specific block on the Hyperliquid EVM blockchain. This Otterscan-specific method optimizes data transfer by removing verbose fields like logs and providing pagination support for blocks with many transactions.

​
Parameters

  1. block number (integer, required): The block number to retrieve transactions from
  2. page number (integer, required): The page number to retrieve (0-indexed)
  3. page size (integer, required): The number of transactions per page

​
Response

The method returns a paginated response with transaction data and receipts.

​

    • gasUsed — total gas used
    • baseFeePerGas — base fee per gas
  • receipts — array of transaction receipts (simplified, without logs)
    • transactionHash — hash of the transaction
    • status — success status (0x1 for success, 0x0 for failure)
    • cumulativeGasUsed — cumulative gas used up to this transaction
    • gasUsed — gas used by this transaction
    • effectiveGasPrice — actual gas price paid
    • contractAddress — contract address created (if applicable)

​
Pagination example

To retrieve all transactions from a large block: 
// Page 0: transactions 0-9
params: [1000, 0, 10]

// Page 1: transactions 10-19
params: [1000, 1, 10]

// Page 2: transactions 20-29
params: [1000, 2, 10]

​
Use cases

The ots_getBlockTransactions method is essential for:
  • Block explorers: Display transaction lists with pagination controls
  • Large block handling: Efficiently process blocks with many transactions
  • Performance optimization: Reduce bandwidth by excluding verbose log data
  • Transaction indexing: Build transaction databases with pagination
  • API rate limiting: Control data flow with page-based retrieval
  • Mobile applications: Optimize data usage with smaller response sizes
  • Real-time monitoring: Process new blocks transaction by transaction
  • Data analysis: Systematically analyze all transactions in blocks
  • Archive services: Export block transaction data in manageable chunks
  • User interfaces: Implement infinite scroll or pagination in dApps
This method is particularly valuable for handling blocks with hundreds or thousands of transactions, where retrieving all data at once would be inefficient.
