# ResQ.Blockchain.INeoClient

### [ResQ.Blockchain](./ResQ.Blockchain.md "ResQ.Blockchain")

## INeoClient Interface

Interface for Neo N3 blockchain operations.

```csharp theme={null}
public interface INeoClient
```

Derived\
↳ [MockNeoClient](./ResQ.Blockchain.MockNeoClient.md "ResQ.Blockchain.MockNeoClient")

### Example

```csharp theme={null}
// Dependency injection registration
services.AddSingleton<INeoClient, MockNeoClient>();

// Usage
public class IncidentService
{
    private readonly INeoClient _neoClient;
    
    public IncidentService(INeoClient neoClient)
    {
        _neoClient = neoClient;
    }
    
    public async Task RecordIncidentAsync(BlockchainEvent evt)
    {
        var result = await _neoClient.RecordEventAsync(evt);
        if (result.IsConfirmed)
        {
            Console.WriteLine($"Recorded: {result.TransactionHash}");
        }
    }
}
```

### Remarks

This interface defines the contract for interacting with the Neo N3 blockchain.
Implementations provide methods for recording events, verifying attestations,
and querying blockchain state. Use [MockNeoClient](./ResQ.Blockchain.MockNeoClient.md "ResQ.Blockchain.MockNeoClient") for testing
and development without a real blockchain connection.
