Syntax

public static class SuspendNetworkExtensions

Methods

SuspendNetworkAsync(ConsensusClient, SuspendNetworkParams, Action<IConsensusContext>?)

Suspends the network at the specified consensus time.
This does not result in any network changes or upgrades and requires manual intervention to restart the network.

Declaration

public static Task<TransactionReceipt> SuspendNetworkAsync(this ConsensusClient client, SuspendNetworkParams suspendParams, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the administrative command.
SuspendNetworkParams	suspendParams	The parameters for suspending the network, including the consensus time at which nodes will stop services.
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 success.

Remarks

This operation must be submitted by a privileged account having access rights to perform this operation.

Examples

// Freeze the entire network at a future consensus timestamp. Every
// node will stop accepting transactions at that moment. Requires
// the superuser payer — reserved for emergency maintenance.
var receipt = await client.SuspendNetworkAsync(new SuspendNetworkParams
{
    Consensus = new ConsensusTimeStamp(DateTime.UtcNow.AddHours(1))
});
Console.WriteLine($"Suspend status: {receipt.Status}");

Exceptions

Type	Condition
ArgumentException	If required arguments are missing or invalid.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node refused the transaction. Only a code about the transaction itself proves it did not execute; any other code leaves the outcome unknown, so settle it by its transaction id on a mirror node rather than resubmitting it (see PrecheckException).
ConsensusException	If the outcome could not be confirmed: the transaction may have executed, so settle it by its transaction id on a mirror node rather than resubmitting it.
TransactionException	If the network rejected the request as invalid or had missing data.
