02.HOW IT WORKS// parallel delivery to leaders

One request, parallel delivery.

The Solana TPU Sender uses parallel delivery through staked connections using SWQoS. Client access is available over HTTP JSON-RPC and a separately authorized QUIK transport.

◆ HTTP JSON-RPC - signed base64 transaction via sendTransaction
◆ QUIK transport - port 8090, separate public-key authorization
◆ Confirm landing by signature through RPC

03.DELIVERY// multi-channel · SWQoS

Parallel delivery

A single sendTransaction request is forwarded through multiple enabled channels. Alternative paths keep trying if one route fails.

Staked TPU connections

SWQoS gives stake-backed connections prioritized ingress capacity at validator leaders. Transaction inclusion and ordering still depend on network conditions.

Choose your transport

HTTP JSON-RPC accepts signed base64 transactions. The QUIK endpoint uses separate public-key authorization. Both access paths connect to the same TPU delivery product; request setup from Supanode.
