Contains one variant per dispatchable that can be called by an extrinsic.

Variants

register

Fields

id: ParaId

genesis_head: HeadData

validation_code: ValidationCode

Register head data and validation code for a reserved Para Id.

Arguments

• origin: Must be called by a Signed origin.
• id: The para ID. Must be owned/managed by the origin signing account.
• genesis_head: The genesis head data of the parachain/thread.
• validation_code: The initial validation code of the parachain/thread.

Deposits/Fees

The origin signed account must reserve a corresponding deposit for the registration. Anything already reserved previously for this para ID is accounted for.

Events

The Registered event is emitted in case of success.

force_register

Fields

who: T::AccountId

deposit: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance

id: ParaId

genesis_head: HeadData

validation_code: ValidationCode

Force the registration of a Para Id on the relay chain.

This function must be called by a Root origin.

The deposit taken can be specified for this registration. Any ParaId can be registered, including sub-1000 IDs which are System Parachains.

deregister

Fields

id: ParaId

Deregister a Para Id, freeing all data and returning any deposit.

The caller must be Root, the para owner, or the para itself. The para must be a parathread.

swap

Fields

id: ParaId

other: ParaId

Swap a parachain with another parachain or parathread.

The origin must be Root, the para owner, or the para itself.

The swap will happen only if there is already an opposite swap pending. If there is not, the swap will be stored in the pending swaps map, ready for a later confirmatory swap.

The ParaIds remain mapped to the same head data and code so external code can rely on ParaId to be a long-term identifier of a notional “parachain”. However, their scheduling info (i.e. whether they’re a parathread or parachain), auction information and the auction deposit are switched.

force_remove_lock

Fields

para: ParaId

Remove a manager lock from a para. This will allow the manager of a previously locked para to deregister or swap a para without using governance.

Can only be called by the Root origin.

reserve

Fields

Reserve a Para Id on the relay chain.

This function will reserve a new Para Id to be owned/managed by the origin account. The origin account is able to register head data and validation code using register to create a parathread. Using the Slots pallet, a parathread can then be upgraded to get a parachain slot.

Arguments

• origin: Must be called by a Signed origin. Becomes the manager/owner of the new para ID.

Deposits/Fees

The origin must reserve a deposit of ParaDeposit for the registration.

Events

The Reserved event is emitted in case of success, which provides the ID reserved for use.
