# Node

Information about nodes.

## What is a node

Solana nodes are essential for interacting with the Solana blockchain. They provide access to real-time network data and allow bots to execute transactions. Choosing the right node can significantly impact a bot's speed and performance.

## Types of nodes

### RPC & Websockets

Websockets is a good starting point, but they're slower and less stable than gRPC. So I do not recommend using them at all. If you decide you want to use them, then make sure your node also has a high RPS (Rate limit per second) of at least 200/s.

### gRPC

Node that supports gRPC is better. gRPC connection is much more stable, faster and doesn't miss transactions unlike websockets.

## For Zed

Usage of websockets is not recommended, since that is slow and unstable. However if you do insist on using them, then make sure the node supports a high amount of requests per second. If your websocket node does not have a high RPS, then only PumpFun mode will work, and not Raydium.

<mark style="color:yellow;">Strong recommendation for gRPC</mark>, those are much faster, and therefore allow you to make more money.
