Solana TPU Sender with SWQoS

Landing.fast by Supanode.xyz is a TPU Sender that delivers transactions directly to slot leaders through stake-weighted TPU channels. It offers dual-path routing via SWQoS and the Jito Bundle Engine, with JSON-RPC, HTTP support across multiple global regions. Your transaction is pushed straight to the active slot leader bypassing the crowded public RPC layer, where transactions are frequently dropped under heavy load.

Supanode TPU Sender routes your Solana transactions through stake-weighted channels directly to the current slot leader. Every submission travels over high-stake validator connections that sidestep the public RPC congestion that typically drops transactions during periods of high network activity. Dual-path delivery sends your transaction through both our SWQoS channels and the Jito Bundle Engine at the same time whichever path lands first wins.

How It Works#

                            ┌─► Jito Engine ──────┐
Your App ──► Landing.fast ──┤                     ├──► Slot Leader
                            └─► SWQoS Connection ─┘

Your app submits a transaction with tips to any Landing.fast endpoint.
Landing.fast verifies the tip and forwards the transaction over stake-weighted connections to the current block producer and the Jito Bundle Engine in parallel.
The leader picks up the transaction from whichever route arrives first.
