How to Use It

// yarn add @tatumio/tatum

import { TatumSDK, Solana, Network } from '@tatumio/tatum'

const tatum = await TatumSDK.init<Solana>({ network: Network.SOLANA })

const res = await tatum.rpc.getBlocks(5,10)

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs


The getBlocks method returns a list of confirmed blocks between two specified slots. This can be useful when needing to examine a specific range of blocks for transaction analysis, data verification, or other blockchain analysis tasks.


  • endSlot (number, required): This is the upper limit of the slot range from which blocks are to be returned.

  • startSlot (number, optional): This is the lower limit of the slot range. If not provided, the method will return blocks from the start of the blockchain to the endSlot. Note that startSlot must be no more than 500,000 blocks lower than the end_slot.

  • options (object, optional): This object can contain the following fields:

    • commitment(string, optional): Specifies the level of commitment to apply when fetching data.

      • Values: finalized confirmed Note that processed is not supported.

Return Object

The method returns an array of integers, each representing a confirmed block between startSlot and either endSlot (if provided) or the latest confirmed block, inclusive. The maximum range allowed is 500,000 slots.
