Diagram comparing the standard path (public RPC, shared queues and lower-priority capacity at the leader's TPU) with Private TPU Send, which delivers single transactions or atomic bundles over a staked QUIC connection into the stake-weighted priority capacity of the slot leader's TPU. — Private TPU Send: simplified diagram

How it works

Private TPU Send delivers your transactions straight to the TPU of the current and upcoming leaders, over QUIC connections prioritized by stake (stake-weighted QoS, often called SWQoS).

Your transactions skip public RPC nodes and the queues shared with retail traffic.

It also accepts atomic bundles: put a target transaction from Private Orderflow first and your backrun right behind it, and the validator executes them together and in order, or not at all.

Key benefits

Atomic bundles in our validators' leader slots: your backrun lands directly behind its target, or not at all.
A higher landing rate, especially when the network is congested.
Shorter and more predictable time from sending to block inclusion.
No public intermediaries that could copy or front-run your strategy.
Your transactions are excluded from the Private Orderflow stream.
