Bumps @ethereumjs/tx from 3.5.2 to 10.1.2.

Release notes

Sourced from @​ethereumjs/tx's releases.

@​ethereumjs/tx v10.1.2

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/tx

@ethereumjs/tx defines typed transactions, intrinsic gas calculation, and pre-execution validation — the layer that decides whether a transaction is well-formed and what minimum gas it must carry before the VM ever runs it. Within the 10.1.2 round, Amsterdam adds two floor-pricing EIPs that tighten those minimums and feed directly into EIP-8037 regular-gas accounting downstream.

If you construct or validate transactions for Amsterdam testnets or EST fixtures, these floors are usually why a seemingly small tx suddenly needs a higher gasLimit or a non-zero baseFeePerGas on the containing block.

At a glance

• EIP-7976 — uniform calldata floor: 4 tokens per calldata byte (replacing the zero/non-zero split for floor purposes).
• EIP-7981 — access-list byte floor for typed txs (types 1–4): (20 × addresses + 32 × keys) × 4 tokens per byte.
• Both enforced in getValidationErrors() and intrinsic gas helpers when Hardfork.Amsterdam is active.

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)

The calldata floor means txRegularGas in the VM becomes (conceptually) max(raw_regular_gas, calldata_floor) under EIP-8037. When writing tests, set baseFeePerGas: 1n on the block header and ensure gasPrice / maxFeePerGas on the tx is high enough to satisfy EIP-1559 checks alongside the new floors:

import { Common, Hardfork, Mainnet } from '@ethereumjs/common'
import { createLegacyTx } from '@ethereumjs/tx'
const common = new Common({ chain: Mainnet, hardfork: Hardfork.Amsterdam })
const tx = createLegacyTx(
{
gasLimit: 100_000n,
gasPrice: 10n,
data: new Uint8Array(100), // calldata floor scales with byte count
},
{ common },
)
const errors = tx.getValidationErrors()
// [] when gasLimit covers max(intrinsic, floor)

See the Amsterdam transaction validation section for the full token arithmetic and interaction with EIP-8037.
