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 Fungibles: FungiblesMutate<Self::AccountId, AssetId = Self::AssetId> + FungiblesMetadataInspect<Self::AccountId>

Fungibles implementation for both internal and external stablecoins.

type AssetId: Parameter + Member + Clone + MaybeSerializeDeserialize + MaxEncodedLen + Ord

Asset identifier type.

type MaximumIssuance: Get<<<Self as Config>::Fungibles as FungiblesInspect<<Self as Config>::AccountId>>::Balance>

Maximum allowed internal issuance across the entire system.

type ManagerOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = PsmManagerLevel>

Origin allowed to update PSM parameters.

Returns PsmManagerLevel to distinguish privilege levels:

• Full (via GeneralAdmin): Can modify all parameters
• Emergency (via EmergencyAction): Can modify circuit breaker status, per-asset ceiling weights, and the global max PSM debt ratio.

type WeightInfo: WeightInfo

A type representing the weights required by the dispatchables of this pallet.

type InternalAsset: FungibleMutate<Self::AccountId, Balance = <<Self as Config>::Fungibles as FungiblesInspect<<Self as Config>::AccountId>>::Balance> + FungibleMetadataInspect<Self::AccountId>

The internal asset as a single-asset fungible type.

Typically ItemOf<Asset, InternalAssetId, AccountId>. Must use the same Balance type as Asset.

type FeeDestination: Get<Self::AccountId>

Account that receives internal fees from minting and redemption.

Must exist before any swap; initialized at genesis and migration via Pallet::ensure_account_exists.

type PalletId: Get<PalletId>

PalletId for deriving the PSM account.

type MinSwapAmount: Get<<<Self as Config>::Fungibles as FungiblesInspect<<Self as Config>::AccountId>>::Balance>

Minimum swap amount.

type MaxExternalAssets: Get<u32>

Maximum number of approved external assets.

type BenchmarkHelper: BenchmarkHelper<Self::AssetId, Self::AccountId>

Helper for benchmarks to create an external asset with correct metadata.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
