One packet, straight to the leader.
Your bot sends each signed transaction as a single UDP packet with your API key in front. TPU Sender hands it to the current slot leader - no HTTP round trip, no public queue.
How does the TPU Sender land transactions?
Your bot sends each signed transaction as a single UDP packet with your API key in front. TPU Sender delivers it straight to the current slot leader, with no HTTP round trip and no public queue. In a live benchmark across 18 submission services it landed the most transactions.
Do I need to change my code?
A little. Instead of an RPC sendTransaction call, you send the serialized transaction as one UDP packet with your API key in front - a few lines in Rust, TypeScript, or Python. A ready Rust client comes with onboarding.
How is the TPU Sender priced?
Flat monthly per sending server, in two plans: Standard for a regular trading flow and High-volume for strategies that fire many transactions per opportunity. There is no per-transaction charge; exact prices are on the pricing page.
What does a packet look like?
One UDP datagram: your 32-byte API key, then the signed transaction in the standard Solana wire format, up to 1,232 bytes. There is no response - you confirm landing by signature through RPC.
Which region should I send to?
Frankfurt or Amsterdam - the one closest to your sending server. The endpoint is private and comes with your API key.
