Expand description

Create a PSM for a given internal asset.

If Config::CreateOrigin resolves to Some(account), takes a Config::Consideration deposit from that account for the instance’s footprint (refunded on remove_psm). If it resolves to None, no deposit is taken. The full_admin and emergency_admin origins are set from the provided arguments and may later be reassigned via Pallet::set_full_admin / Pallet::set_emergency_admin.

§Dispatch Origin

Config::CreateOrigin, parameterised by internal_asset. With the recommended EnsureAssetOwner this is a signed origin that owns internal_asset.

§Parameters

internal_asset: The internal stablecoin keying the new PSM. Must exist in the fungibles backend; must not already have a PSM registered.
full_admin: Origin granted full management of the new PSM.
emergency_admin: Origin granted emergency management of the new PSM.
fee_destination: Account that will receive mint/redeem fees.
max_debt: Initial absolute internal-asset debt ceiling.
min_swap_amount: Minimum swap amount for this instance, in internal-asset units. Must be non-zero.

§Errors

[DispatchError::BadOrigin]: The origin is not permitted by Config::CreateOrigin.
Error::PsmAlreadyExists: A PSM is already registered for internal_asset.
Error::ZeroMinSwapAmount: min_swap_amount is zero.
Error::AssetDoesNotExist: The internal asset does not exist.
Any error from establishing the Config::Consideration deposit when one is needed (e.g. the account cannot afford it).

§Events

Event::PsmCreated.
