# Jito and Astralane Explained

## 🧠 Jito, Rate Limits & Astralane

This page breaks down how **Jito** works, its **rate limits**, what a **Jito UUID** is, and why we use **Astralane** as a solution.

***

### ⚙️ What is Jito?

[Jito](https://jito.network/) is a high-performance MEV infrastructure for Solana. It allows you to send **bundles of transactions** directly to validators through a private relay for:

* Backruns
* Arbitrage
* Sandwiches
* Priority access to blockspace

This is essential for snipers and searchers who need faster execution than the public mempool offers.

***

### 🚫 Jito Rate Limits

Jito enforces **IP-based rate limits** to prevent abuse of their relayer infrastructure.

* If you do **not** have a Jito UUID:\
  → **Only 1 transaction/bundle per second is allowed**
* If you **do** have a Jito UUID (authenticated client):\
  → You can send **up to 5 transactions/bundles per second**

This is a significant limitation for bots or sniper tools trying to launch across many wallets at once.

***

### 🧾 What is a Jito UUID?

A **Jito UUID** is a unique identifier provided by the Jito team when you register with them. It essentially gives your client "authenticated" status with higher throughput.

> Without a UUID, Jito considers your IP unauthenticated and will restrict you to 1 RPS (request per second).

### 🛰️ Enter Astralane

[Astralane](https://astralane.gitbook.io/docs/low-latency/quickstart) is a low-latency transaction relay network built specifically for Solana bots and snipers.

It solves two key problems:

#### ✅ 1. Bypassing Jito Rate Limits

* Astralane provides **many RPS (requests per second)** directly.
* This allows you to skip the hassle of setting up proxies or worrying about Jito UUID limits.
* Each request goes through their optimized infra, ensuring you’re not bottlenecked by IP rate limits.

#### ✅ 2. Avoiding the Proxy Maze

Normally, to bypass Jito's rate limits without a UUID, you’d need to buy and rotate **proxy IPs** (which costs money, introduces latency, and can break).

Astralane makes that irrelevant by letting you:

* Send **many requests per second**
* Avoid using any proxies
* Skip setting up a UUID with Jito

### 🤖 TL;DR for Builders

| Feature          | Jito (No UUID) | Jito (With UUID)      | Astralane               |
| ---------------- | -------------- | --------------------- | ----------------------- |
| RPS (Tx/sec)     | 1              | 5                     | 20+ (depending on plan) |
| Needs Proxy?     | ✅ Yes          | ✅ Maybe (for scale)   | ❌ No                    |
| Setup Complexity | Medium         | High (needs Jito reg) | Low                     |
| Best For         | Light testing  | Mid-volume sniping    | High-performance bots   |

### 🧵 Summary

* Jito is essential for fast Solana trading, but rate limits can choke throughput.
* UUIDs raise limits to 5 tx/sec but require setup.
* Astralane provides high-RPS access without proxies or UUID headaches.
