p	CantonGenerateParams<ApplyChainUpdatesParams>

Returns

Promise<{ actAs: string[]; commandId: string; commands: ({ CreateAndExerciseCommand: { choice: string; choiceArgument: unknown; createArguments: unknown; templateId: string; }; } | { CreateCommand: { createArguments: unknown; templateId: string; }; } | { ExerciseByKeyCommand: { choice: string; choiceArgument: unknown; contractKey: unknown; templateId: string; }; } | { ExerciseCommand: { choice: string; choiceArgument: unknown; contractId: string; templateId: string; }; })[]; deduplicationPeriod?: { DeduplicationDuration: { value: { nanos: number; seconds: number; unknownFields?: { fields: {[key: string]: { fixed32?: ... | ...; fixed64?: ... | ...; lengthDelimited?: ... | ...; varint?: ... | ...; }; }; }; }; }; } | { DeduplicationOffset: { value: number; }; } | { Empty: Record<string, never>; }; disclosedContracts?: { contractId?: string; createdEventBlob: string; synchronizerId?: string; templateId?: string; }[]; minLedgerTimeAbs?: string; minLedgerTimeRel?: { nanos: number; seconds: number; unknownFields?: { fields: {[key: string]: { fixed32?: number[]; fixed64?: number[]; lengthDelimited?: string[]; varint?: number[]; }; }; }; }; packageIdSelectionPreference?: string[]; prefetchContractKeys?: { contractKey: unknown; templateId: string; }[]; readAs?: string[]; submissionId?: string; synchronizerId?: string; userId?: string; workflowId?: string; }>

execute()

execute(chain: CantonChain, params: ExecuteApplyChainUpdatesParams): Promise<ExecuteApplyChainUpdatesResult>

Defined in: cct/canton/token-pool/operations/apply-chain-updates.ts:183

Validates the wallet, derives sender from wallet.party, builds the commands, and submits via submitCantonCommands. Returns the confirmed updateId plus the raw ledger response for result parsing.

Parameters

Parameter	Type
chain	CantonChain
params	ExecuteApplyChainUpdatesParams

Returns

Promise<ExecuteApplyChainUpdatesResult>

Overrides

CantonOperation.execute

---

generate()

generate(chain: CantonChain, params: CantonGenerateParams<ApplyChainUpdatesParams>): Promise<UnsignedCantonTx>

Defined in: cct/canton/operation.ts:110

Run prepare and buildCommands; no signing.

Parameters

Parameter	Type
chain	CantonChain
params	CantonGenerateParams<ApplyChainUpdatesParams>

Returns

Promise<UnsignedCantonTx>

Inherited from

CantonOperation.generate

---

parse()

protected parse(params: CantonGenerateParams<ApplyChainUpdatesParams>): CantonGenerateParams

Defined in: cct/canton/operation.ts:91

Normalize params without mutating the caller's input.

The default returns params unchanged. Override whenever Parsed differs from CantonGenerateParams<P>, e.g. to parse party IDs / instrument IDs into validated forms or apply defaults.

Parameters

Parameter	Type
params	CantonGenerateParams<ApplyChainUpdatesParams>

Returns

CantonGenerateParams

Inherited from

CantonOperation.parse

---

prepare()

protected prepare(params: CantonGenerateParams<ApplyChainUpdatesParams>): CantonGenerateParams

Validates and normalizes params for generation or execution.

Parameters

Parameter	Type
params	CantonGenerateParams<ApplyChainUpdatesParams>

Returns

CantonGenerateParams

Inherited from

CantonOperation.prepare

Defined in: cct/canton/token-pool/operations/apply-chain-updates.ts:92

Validates the pool target and that at least one add/remove is specified.

Parameters

Parameter	Type
p	GenerateApplyChainUpdatesParams

Returns
