@ethereumjs/common v3.0.0-beta.3

Beta 3 release for the upcoming breaking release round on the EthereumJS monorepo libraries, see the Beta 1 release notes for the main long change set description as well as the Beta 2 release notes for notes on some additional changes (CHANGELOG).

Merge Hardfork Default

Since the Merge HF is getting close we have decided to directly jump on the Merge HF (before: Istanbul) as default for the Common library and skip the London default HF as we initially intended to set (see Beta 1 CHANGELOG), see PR #2087.

If you want instantiate the library with an explicit HF set you can do:

import { Common, Chain, Hardfork } from '@ethereumjs/common'

const common = new Common({ chain: Chain.Mainnet, hardfork: Hardfork.London })
