Syntax

public static class SignScheduleExtensions

Methods

SignScheduleAsync(ConsensusClient, EntityId, Action<IConsensusContext>?)

Adds signatures to an existing scheduled transaction. If the additional signatures satisfy all remaining signature requirements, the scheduled transaction may execute immediately (unless delayed).

Declaration

public static Task<TransactionReceipt> SignScheduleAsync(this ConsensusClient client, EntityId schedule, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the request.
EntityId	schedule	The address of the schedule entity to sign.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<TransactionReceipt>	A transaction receipt indicating a successful operation.

Examples

// Add a signature to a pending schedule. The schedule executes
// automatically once every signing requirement of the inner
// transaction is satisfied — no explicit "execute" call is needed.
// The client context's Signatory provides the key being added.
var receipt = await client.SignScheduleAsync(scheduleId);
Console.WriteLine($"Sign status: {receipt.Status}");

Exceptions

Type	Condition
ArgumentOutOfRangeException	If required arguments are missing.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node rejected the request upon submission.
ConsensusException	If the network was unable to come to consensus before the duration of the transaction expired.
TransactionException	If the network rejected the request as invalid or had missing data.

SignScheduleAsync(ConsensusClient, SignScheduleParams, Action<IConsensusContext>?)

Adds signatures to an existing scheduled transaction. If the additional signatures satisfy all remaining signature requirements, the scheduled transaction may execute immediately (unless delayed).

Declaration

public static Task<TransactionReceipt> SignScheduleAsync(this ConsensusClient client, SignScheduleParams signParams, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the request.
SignScheduleParams	signParams	The details of the schedule signing request.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<TransactionReceipt>	A transaction receipt indicating a successful operation.

Examples

// Add a co-signer's signature via params. Use this when the required
// key is not already in the client's context — e.g., a multi-party
// transfer where an independent signer submits their signature from
// a service that does not hold the primary payer's key.
var receipt = await client.SignScheduleAsync(new SignScheduleParams
{
    Schedule = scheduleId,
    Signatory = coSignerKey
});
Console.WriteLine($"Sign status: {receipt.Status}");

Exceptions

Type	Condition
ArgumentOutOfRangeException	If required arguments are missing.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node rejected the request upon submission.
ConsensusException	If the network was unable to come to consensus before the duration of the transaction expired.
TransactionException	If the network rejected the request as invalid or had missing data.
