How to Use It

// yarn add @tatumio/tatum

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

  • limit (number, optional): This is the number of blocks to be returned starting from the startSlot. If not provided, the method will return all blocks from the startSlot to the end of the blockchain. Note that limit must be no more than 500,000 blocks higher than the startSlot.

  • 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 starting from the startSlot and up to the limit blocks, inclusive.
