FAQ

What is Blocklander?

Blocklander is a Solana transaction submission service built for ultra-low latency. It simultaneously routes transactions to multiple Solana validators and Jito, giving high-frequency traders, bots, and snipers multiple paths to successfully land transactions under all network conditions.

Where are Blocklander nodes located?

Blocklander endpoints are distributed across Europe and America. For best performance, we load balance the endpoint closest to where your application is hosted, or override with the location of your choice.

How much does it cost?

Using Blocklander is free. A small transaction tip is required, and you or your app user can choose the amount. The more you tip, the faster and more reliable your transactions.

What is the minimum tip required?

To dual-route transactions via both staked connections and Jito, the minimum tip is 0.0005 SOL (500k lamports). This ensures participation in Jito’s MEV auction.

Why do I need to tip?

Tips are necessary for Jito’s MEV auction, while priority fees improve your transaction’s priority with validators. Blocklander submits your transaction simultaneously to Jito and the current block producer, maximizing inclusion probability.

Why should I use Blocklander instead of a standard RPC or other transaction router ?

• Speed : Blocklander is faster than any other transaction router by leveraging low lowest level programming, using the best infra co-located with your app and parallelising transaction sends with optimal strategies
• Reliability : Transactions are routed in parallel across Jito and +10 stake-weighted validators, ensuring balanced distribution with no favoritism, just raw reliability and speed
• MEV Protection : By submitting transactions to the Jito MEV auction and stake-weighted validators in parallel, we maximize your chances of placing transactions at the top of a block, critical for protection against MEV attacks
• Value : Minimum tips are 50% below our competitors and we’re still faster! This means 50% less cost (500k lamports or 0.0005 SOL per transaction) for you and your users with better speed and reliability
• Trusted by leading Solana Apps : Join the leading cohort of apps on Solana that use Blocklander for serving their customers with reliable & fast transactions. Notable ones include Dexscreener, Axiom, BloomBot & more.
