Release round overview

Welcome to 10.1.2 — a coordinated release across all active @ethereumjs/* libraries on the 10.1.x line. If you have been following the upcoming Amsterdam hardfork, this is our first experimental preview ready to try out: a largely complete nine-EIP Hardfork.Amsterdam bundle, currently aligned with tests-bal@v7.1.0 and BAL devnet-7.

Amsterdam is still in flux — please do not use this in production yet — and we expect further 10.1.x releases as the spec and official tests evolve. The sections below cover this package only; for the full fork picture (EIP list, examples, release ↔ spec tracking), see the @​ethereumjs/vm Amsterdam overview. On Osaka or earlier hardforks? Nothing changes unless you explicitly select Hardfork.Amsterdam.

@ethereumjs/util

@ethereumjs/util is the shared toolbox the whole monorepo builds on — bytes, accounts, addresses, and fork-specific helpers that higher layers import rather than reimplement. Within the 10.1.2 round, the headline addition is a dedicated bal module for working with EIP-7928 Block Level Access Lists outside of live execution: parsing fixtures, validating structure, computing the header hash, and writing test tooling. The VM performs accumulation during runBlock(); Util gives you the portable data model and canonical encoding.

This package also picks up two cross-environment fixes: Account.isEmpty() for partial accounts, and a new isDebugEnabled() helper used across the monorepo for safe DEBUG checks in browsers and Web Workers.

At a glance

• New bal module: BlockLevelAccessList, JSON/RLP factories, validation helpers, and hash() for offline BAL work.
• Fix Account.isEmpty() when called on partial accounts (e.g. state trie reads), see PR #​4268.
• Add isDebugEnabled(namespace) — avoids ReferenceError in workers where process is undeclared, see PR #​4265.

Amsterdam (experimental)

Behaviour may change in subsequent 10.1.x patch releases.
Spec snapshot: tests-bal@v7.1.0 · Testnet: BAL devnet-7
Fork overview: Amsterdam hardfork (experimental)

Typical Util workflow: ingest a BAL JSON fixture (from a test vector or RPC payload), validate structure and gas-limit footprint, and verify the hash against an expected blockAccessListHash. Example from packages/util/examples/bal.ts:

import {
  bytesToHex,
  createBlockLevelAccessListFromJSON,
  validateBlockAccessListHashFromJSON,
  validateBlockAccessListStructure,
} from '@​ethereumjs/util'

const balJson = [
  {
    address: '0x0000000000000000000000000000000000000001',
    storageChanges: [],
    storageReads: [],
    balanceChanges: [{ blockAccessIndex: '0x01', postBalance: '0x03e8' }],
    nonceChanges: [],
    codeChanges: [],
  },
]

const bal = createBlockLevelAccessListFromJSON(balJson)
validateBlockAccessListStructure(bal)
validateBlockAccessListHashFromJSON(balJson, bal.hash())

console.log(`BAL hash: ${bytesToHex(bal.hash())}`)

Key exports include createBlockLevelAccessListFromJSON / FromRLP, validateBlockAccessListStructure, validateBlockAccessListGasLimit, hashBlockAccessListFromJSON, and equalsBlockAccessList. See the Module: bal section in the README for the full at-a-glance map.
