Transform a list of Commitments to Blob Versioned Hashes.

Imports

Named
import { Blobs } from 'ox'

Examples

import { Blobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = Blobs.from('0xdeadbeef')
const commitments = Blobs.toCommitments(blobs, { kzg })
const versionedHashes = Blobs.commitmentsToVersionedHashes(commitments)

['0x...', '0x...']

Configuring Return Type

It is possible to configure the return type for the Versioned Hashes with the as option.

import { Blobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = Blobs.from('0xdeadbeef')
const commitments = Blobs.toCommitments(blobs, { kzg })
const versionedHashes = Blobs.commitmentsToVersionedHashes(commitments, {
  as: 'Bytes', 
})

[Uint8Array [ ... ], Uint8Array [ ... ]]

Versioning Hashes

It is possible to configure the version for the Versioned Hashes with the version option.

import { Blobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = Blobs.from('0xdeadbeef')
const commitments = Blobs.toCommitments(blobs, { kzg })
const versionedHashes = Blobs.commitmentsToVersionedHashes(commitments, {
  version: 2, 
})
