Why TPU Sender
Direct TPU Access
Stake-weighted QUIC channels route transactions straight to the slot leader - no RPC delays.
Dual-Path Routing
Every transaction is sent via SWQoS and Jito Block Engine simultaneously. Whichever path lands first wins.

FAQ
What is TPU Sender?+
TPU Sender is a Solana transaction delivery service that routes your transactions through stake-weighted channels directly to the current slot leader's Transaction Processing Unit (TPU), bypassing the traditional RPC relay path.
How does dual-path routing work?+
Every transaction is simultaneously sent to the Solana validator through two independent paths: SWQoS stake-weighted channels to the Validator's Priority Queue, and Jito Block Engine to the Bundle Stage. The first path to land the transaction wins, maximizing your landing rate.
Which SDK languages are supported?+
We support Rust, TypeScript, Python. Integration is a single endpoint swap — replace your existing RPC URL with location.landing.fast and add your API key header.
What's the pricing model?+
Tip-based pricing starting from 0.001 SOL per transaction. No monthly subscription, no minimum commitment.
Is using TPU Sender legal?+
Yes. TPU Sender uses Solana's native stake-weighted QoS mechanism and Jito's public Block Engine API. These are standard, documented protocol features available to all validators and stakers.
