moonbeam-foundation/moonbeam runtime-1200 on GitHub

Description

This runtime introduces many changes to our Ethereum layer, specially around the EIP 1559. Here are the important parts:

EVM 0.33.1 - London support

EIP-3198: BASEFEE opcode
EIP-3529: Reduction in refunds
EIP-3541: Reject new contracts starting with the 0xEF byte

Ethereum 0.11.1

EIP-2718: Typed transactions
EIP-2930: Optional access lists
EIP-1559: Fee market change

Ethereum API - Changes

new rpc eth_feeHistory: Returns transaction fee data for up to 1,024 blocks.
new property block.baseFeePerGas: baseFeePerGas used for the given block
new property transactionReceipt.effectiveGasPrice: gas price being used for the transaction

new property transaction.accessList: is an array of type [[{20 bytes}, [{32 bytes}...]]...], storing the contract address and the storage keys. Ex:

[
  [
    "0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae",
    [
     "0x0000000000000000000000000000000000000000000000000000000000000003",
     "0x0000000000000000000000000000000000000000000000000000000000000007"
    ]
  ], [
    "0xbb9bc244d798123fde783fcc1c72d3bb8c189413",
    []
  ]
]

new property transaction.maxFeePerGas: how much BaseFee the transaction is allowed to pay.
new property transaction.maxPriorityFeePerGas: Correspond to the "tip" to the miner. (Note: It is currently included in the normal fees, being 20% to parachain bond and 80% burnt. This might change in the future)
new property transaction.type: The current type of transaction 0 (Legacy), 1 (EIP-2930), 2 (EIP-1559)
⚠️The base fee used in block is currently constant (1Gwei on Moonbase/Moonriver and 100Gwei on Moonbeam). The call the eth_gasPrice will return that value.

Substrate API (PolkadotJS) - Staking query changes - ⚠️Breaking Change⚠️

⚠️ parachainStaking.executeLeaveCandidates added the weight hint parameter CandidateDelegationCount. It was added after the benchmarking was made more accurate, which also increased the transaction weights (fees).
⚠️parachainStaking.candidateState is now deprecated and won't return any data. It is replaced by the following 3 functions :

parachainStaking.candidateInfo => Returns the CandidateMetadata structure:

 ParachainStakingCandidateMetadata: {
   bond: 'u128',
   delegationCount: 'u32',
   totalCounted: 'u128',
   lowestTopDelegationAmount: 'u128',
   highestBottomDelegationAmount: 'u128',
   lowestBottomDelegationAmount: 'u128',
   topCapacity: 'ParachainStakingCapacityStatus',
   bottomCapacity: 'ParachainStakingCapacityStatus',
   request: 'Option<ParachainStakingCandidateBondLessRequest>',
   status: 'ParachainStakingCollatorStatus' // This was previously named `state`
 }

Exemple:

{
  bond: 1,000,000,000,000,000,000,000
  delegationCount: 1
  totalCounted: 2,000,000,000,000,000,000,000
  lowestTopDelegationAmount: 1,000,000,000,000,000,000,000
  highestBottomDelegationAmount: 0
  lowestBottomDelegationAmount: 0
  topCapacity: Partial
  bottomCapacity: Empty
  request: null
  status: Active
}

parachainStaking.topDelegations => Returns the Delegations structure:

 ParachainStakingDelegations: {
   delegations: 'Vec<ParachainStakingBond>',
   total: 'u128'
 }

Exemple:

{
  delegations: [
    {
      owner: 0xC0F0f4ab324C46e55D02D0033343B4Be8A55532d
      amount: 1,000,000,000,000,000,000,000
    }
  ]
  total: 1,000,000,000,000,000,000,000
}

parachainStaking.bottomDelegations => Returns the same Delegations structure as TopDelegations.
⚠️const parachainStaking.maxDelegatorsPerCandidate => is now replaced by maxTopDelegationsPerCandidate
const parachainStaking.maxTopDelegationsPerCandidate => the max number (u32) of delegations in the TopDelegations (currently set to 300 on all runtimes)
const parachainStaking.maxBottomDelegationsPerCandidate => the max number (u32) of delegations in the BottomDelegations (currently set to 50 on all runtimes). This implies that bottom delegations after 50 will get automatically and instantly revoked (The list, which includes delegations not eligible for rewards, is ordered by staking amount so the lowest staking delegation are the first ones to be revoked)
⚠️event CandidateWentOffline(RoundIndex, T::AccountId) has been replaced by CandidateWentOffline(T::AccountId)
⚠️event CandidateBackOnline(RoundIndex, T::AccountId) has been replaced by CandidateBackOnline(T::AccountId)
event DelegationKicked(T::AccountId, T::AccountId, BalanceOf<T>) has been added => This event is sent when the lowest of the BottomDelegations list is kicked (This happens when the top delegations and bottom delegations are full and a new delegation with higher amount is coming)

Substrate API (PolkadotJS) - Asset manager query changes - ⚠️Breaking Change⚠️

⚠️assetManager.asset_id_units_per_second is now deprecated and won't return any data. It is replaced by the following function :
assetManager.asset_type_units_per_second => Returns u128 being the amount of units charged for an asset, as asset_id_units_per_second, but its a mapping whose key is the assetType and not the assetId
⚠️assetManager.setAssetsUnitsPerSecond changes from requesting (T::AssetId, u128) to requesting (T::AssetType, u128)
⚠️assetManager.registerAsset accepts an additional boolean parameter is_sufficient, that indicates whether an account can exist in storage just by having asset units
⚠️event UnitsPerSecondChanged(T::AssetId, u128) has been replaced by UnitsPerSecondChanged(T::AssetType, u128)
assetManager.asset_type_id => Returns the assetId associated with an assetType (

moonbeam/pallets/asset-manager/src/lib.rs
Line 145 in 59522b7

pub type AssetTypeId<T: Config> = StorageMap<_, Blake2_128Concat, T::AssetType, T::AssetId>;

)
a new extrinsic change_existing_asset_type, which allows to change the assetId associated to an assetType
