Splice.Api.Token.AllocationRequestV1

This module defines the interface for an AllocationRequest, which is an interface that can be implemented by an app to request specific allocations from their users for the purpose of settling a DvP or a payment as part of an app’s workflow.

Interfaces

interface AllocationRequest

A request by an app for allocations to be created to enable the execution of a settlement.

Apps are free to use a single request spanning all senders or one request per sender.

viewtype AllocationRequestView

• Choice AllocationRequest_Reject

  Reject an allocation request.

  Implementations SHOULD allow any sender of a transfer leg to reject the allocation request, and thereby signal that they are definitely not going to create a matching allocation for the settlement.

  Controller: actor

  Returns: ChoiceExecutionMetadata

  Field	Type	Description
  actor	Party	The party rejecting the allocation request.
  extraArgs	ExtraArgs	Additional context required in order to exercise the choice.

• Choice AllocationRequest_Withdraw

  Withdraw an allocation request as the executor.

  Used by executors to withdraw the allocation request if they are unable to execute it; e.g., because a trade has been cancelled.

  Controller: (DA.Internal.Record.getField @"executor" (DA.Internal.Record.getField @"settlement" (view this)))

  Returns: ChoiceExecutionMetadata

  Field	Type	Description
  extraArgs	ExtraArgs	Additional context required in order to exercise the choice.

• Choice Archive

  Controller: Signatories of implementing template

• Method allocationRequest_WithdrawImpl : ContractId AllocationRequest -> AllocationRequest_Withdraw -> Update ChoiceExecutionMetadata

Data Types

data AllocationRequestView

View of AllocationRequest.

Implementations SHOULD make sure that at least all senders of the transfer legs are observers of the implementing contract, so that their wallet can show the request to them.

AllocationRequestView

Field	Type	Description
settlement	SettlementInfo	Settlement for which the assets are requested to be allocated.
transferLegs	TextMap TransferLeg	Transfer legs that are requested to be allocated for the execution of the settlement keyed by their identifier. This may or may not be a complete list of transfer legs that are part of the settlement, depending on the confidentiality requirements of the app.
meta	Metadata	Additional metadata specific to the allocation request, used for extensibility.
