# Geyser gRPC Streaming

## Overview

We use [Yellowstone Dragon's Mouth gRPC](https://github.com/rpcpool/yellowstone-grpc) geyser plugin for our GRPC service. This has proved to be the fastest and most reliable Geyser plugin that we have tested. It is regularly updated and has caused no major issues thus far. Thank you Triton for making this open source and continuing to maintain it! The gRPC proto can be found [here](https://github.com/rpcpool/yellowstone-grpc/tree/master/yellowstone-grpc-proto). Examples can be found for how to use the GRPC service [here](https://github.com/Solana-Vibe-Station/grpc-connection-examples).

### Tiers

gRPC tiers are differentiated by how many concurrent gRPC streams you can have active at any given time. Each gRPC connection allows you to "subscribe" to events of a specific Solana program with filters. You can have multiple subscriptions on a single connection. It is recommended to split high bandwidth requesting subscriptions across multiple connections for better spreading out the load. 

## Pricing

| Tier  | Connections | 1 Day | 1 Week | 1 Month |
| ----- | ----------- | ----- | ------ | ------- |
| Basic | 5           | $15   | $40    | $150    |
| Ultra | 10          | N/A   | N/A    | $200    |
| Elite | 15          | N/A   | N/A    | $250    |

{% hint style="info" %}
We recommend pairing gRPC services with a VPS from our cloud services. Latency and throughput plays a huge role in how fast gRPC can stream updates without lag. See [here](https://docs.triton.one/project-yellowstone/dragons-mouth-grpc-subscriptions#operator-recommandation) for a more detailed explanation.
