Moonbeam Runtime 4000 — What it means for you
This release focuses on major staking architecture updates and key improvements to Ethereum compatibility.
Parachain Staking migration
Migrated from Currency → Fungible trait for better token handling and alignment with Substrate standards.
Developers should now query Balances. Freezes instead of Balances.Locks for staking balances (StakingCollator, StakingDelegator).
New Ethereum feature: EIP-7623
Enables improved smart account behaviors and validation logic (part of the Pectra hard fork)
Additional improvements include:
Allow proxy calls (create_pure, kill_pure) for enhanced account management
Cleanup of old pallets (Assets, AssetManager, Crowdloan-Rewards)
Replacement of deprecated CheckInherents with ConsensusHook for timestamp validation
Fixes to LiquidityRestrictions and dryRunXCM API behavior
Updated runtime benchmarks and weights
Breaking changes:
Collators must upgrade to client v0.48.0 before Runtime 4000 is enacted
Removal of legacy pallets (Assets, Bridge, Crowdloan-Rewards)
Timestamp inherent now provided by client, not runtime
No ABI or gas impacts — just smoother staking logic, updated runtime safety, and improved EVM alignment ahead of future protocol upgrades.
