What is Sender and why is it faster than other transaction sending services?
Sender is a specialized service for ultra-low latency transaction submission. It optimizes transaction latency by sending across all pathways — including Helius, Jito, Harmonic, and Rakurai — simultaneously, providing multiple pathways for your transactions to be included in blocks.With seven regional endpoints, typical land-time is ≤ 1.5 slots.
Can I get a higher Sender API limit than 50 transactions per second (TPS)?

Yes! While the standard limit is 50 TPS per region, you can request higher limits and custom tip arrangements by speaking with our sales team.
How do I set tips and priority fees with Sender?
How do I set tips and priority fees with Sender?
All transactions sent through Sender must include both a tip and a priority fee for optimal performance:Tips: The minimum tip depends on the tier you use. SWQOS-only requires a minimum 0.000005 SOL tip, while Sender Max requires a minimum 0.001 SOL tip, routes across every high-speed pathway, and enters your transaction into a priority tip buffer.Priority Fees: Use
ComputeBudgetProgram.setComputeUnitPrice to prioritize your transaction in the validator queue. Use the Priority Fee API for real-time fee recommendations.Why both are required: Tips give you access to Sender’s prioritized routing pathways and the priority tip buffer, while priority fees improve your transaction’s priority with validators—together they maximize inclusion probability.See the Sender documentation for detailed code examples and implementation guidelines.Need More Help?
