Use case

The adjacentTransactions endpoint is useful for various applications that need to analyze transaction sequences or provide context around specific transactions:

  1. Block explorers can use this to show transactions that occurred before and after a specific transaction, helping users understand the transaction flow.
  2. Analytics tools can use this endpoint to track transaction chains and analyze patterns in transaction sequences.
  3. Wallet applications can provide users with a broader context of their transactions by showing adjacent transactions from the same account or related accounts.
  4. Debugging tools for smart contracts can use this to trace the execution flow of transactions and their effects on the blockchain state.
