@ethereumjs/util v9.1.0

Support for Partial Accounts

For Verkle or other contexts it can be useful to create partial accounts not containing all the account parameters. This is now supported starting with this release, see PR #3269:

import { Account } from '@ethereumjs/util'

const account = Account.fromPartialAccountData({
  nonce: '0x02',
  balance: '0x0384',
})
console.log(`Partial account with nonce=${account.nonce} and balance=${account.balance} created`)

New requests Module

This release introduces a new requests module (see PRs #3372, #3393, #3398 and #3477) with various type and an abstract base class for EIP-7685 general purpose execution layer requests to the CL (Prague hardfork) as well as concrete implementations for the currently supported request types:

• EIP-6110: DepositRequest (Prague Hardfork)
• EIP-7002: WithdrawawlRequest (Prague Hardfork)
• EIP-7251: ConsolidationRequest (Prague Hardfork)

These request types are mainly used within the @ethereumjs/block library where applied usage instructions are provided in the README.
