Lightning-fast Solana transaction sender with p90 sub-slot latency, built for high-frequency traders, bots, and institutional-grade performance.

Astralane’s Iris is the fastest way to send transactions on Solana, engineered for users that can’t afford delays. By combining validator co-location, leader schedule awareness, and optimized routing, Iris achieves 0–1 p90 slot latency and reduces failure rates drastically.

Key benefits:
• Ultra-low latency with global validator co-location
• High reliability even during volatile markets
• Lower costs(cheaper min tip requirements than competing solutions)
• MEV protection to safeguard trades from frontrunning and sandwich attacks

Ideal for high-frequency trading, arbitrage, and market-making strategies, Iris gives you the competitive edge to win on Solana.
