Syntax

public static class UpdateHookStorageExtensions

Methods

UpdateHookStorageAsync(ConsensusClient, UpdateHookStorageParams, Action<IConsensusContext>?)

Update the storage of an EVM hook on the Hedera network.

Declaration

public static Task<TransactionReceipt> UpdateHookStorageAsync(this ConsensusClient client, UpdateHookStorageParams updateParameters, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the update.
UpdateHookStorageParams	updateParameters	The parameters identifying the hook and storage updates to apply.
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 of the operation.

Examples

// Rewrite one or more storage slots on a hook. Use this to maintain
// state (e.g., allow/deny lists) consumed by a contract's hook logic.
// The hook's owner account must sign.
var receipt = await client.UpdateHookStorageAsync(new UpdateHookStorageParams
{
    Hook = hook,
    StorageUpdates = new[]
    {
        new HookStorageEntry(slotKey, slotValue)
    }
});
Console.WriteLine($"Hook update 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 update request as invalid or had missing data.
