@ethereumjs/common v3.0.2
Experimental EIP-4895 Beacon Chain Withdrawals Support
This release comes with experimental EIP-4895 beacon chain withdrawals support, see PR #2353 for the plain implementation and PR #2401 for updated calls for the CL/EL engine API. Also note that there is a new helper module in @ethereumjs/util with a new dedicated Withdrawal class together with additional TypeScript types to ease withdrawal handling.
Withdrawals support can be activated by initializing a respective Common object:
import { Common, Chain } from '@ethereumjs/common'
const common = new Common({ chain: Chain.Mainnet, eips: [4895] })Hardfork-By-Time Support
The Common library now supports setting and retrieving hardforks which are triggered by timestamp instead of a specific block number, see PR #2437. This mechanism will be first applied for the upcoming Shanghai HF. The methods getHardforkByBlockNumber(), setHardforkByBlockNumber() and paramByBlock() have been altered to take in an additional timestamp value, method naming remains for now for backwards compatibility. There are two new utility methods hardforkTimestamp() and nextHardforkBlockOrTimestamp().
