Configuration trait of this pallet.

The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.

Consequently, a runtime that wants to include this pallet must implement this trait.

Required Associated Types

type RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>

type PalletId: Get<PalletId>

PalletId for the crowdloan pallet. An appropriate value could be PalletId(*b"py/cfund")

type SubmissionDeposit: Get<<<<Self as Config>::Auctioneer as Auctioneer<BlockNumberFor<Self>>>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

The amount to be held on deposit by the depositor of a crowdloan.

type MinContribution: Get<<<<Self as Config>::Auctioneer as Auctioneer<BlockNumberFor<Self>>>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

The minimum amount that may be contributed into a crowdloan. Should almost certainly be at least ExistentialDeposit.

type RemoveKeysLimit: Get<u32>

Max number of storage keys to remove per extrinsic call.

type Registrar: Registrar<AccountId = Self::AccountId>

The parachain registrar type. We just use this to ensure that only the manager of a para is able to start a crowdloan for its slot.

type Auctioneer: Auctioneer<BlockNumberFor<Self>, AccountId = Self::AccountId, LeasePeriod = BlockNumberFor<Self>>

The type representing the auctioning system.

type MaxMemoLength: Get<u8>

The maximum length for the memo attached to a crowdloan contribution.

type WeightInfo: WeightInfo

Weight Information for the Extrinsics in the Pallet

Object Safety

This trait is not object safe.
