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 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 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

🧵 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.
In MemeTools, we use Astralane to maximize our sniper performance and avoid infrastructure bottlenecks.
