The fastest and most consistent way to land transactions on Solana

We’ve partnered with top Solana validators to give you access to the highest transaction land rates and lowest slot latency in the Solana ecosystem, surpassing both leading RPC and staked endpoint competitors.

Ideal for professional traders, high-frequency applications, and infrastructure teams requiring zero-compromise execution, Transaction Fastlane provides exclusive routes through partnerships with the top 1% of Solana validators by stake.

Private, Dedicated Pathways
Transactions are routed through dedicated staked validators using Stake-Weighted Quality of Service (SWQoS).

Superior Landing Rates
Avoid dropped transactions even in peak congestion. Backed by enterprise-grade routing and validator connections.

Ultra-Low Slot Latency
Land transactions faster than any shared infrastructure path.

Fully Managed
No custom tooling or validator relationships required. QuickNode handles it all while delivering enterprise-grade uptime and support.
