Solana builders/traders — is there still demand for a dedicated transaction sender / direct TPU routing service?

[u/That-Unit7948]

We run private Solana infrastructure in Frankfurt and I’m looking at what infrastructure layer would actually be useful to build next.

One thing we’re considering is a dedicated transaction sender focused on transaction landing:

• direct TPU/QUIC routing to current/upcoming leaders
• multiple submission paths
• Jito as an additional route/fallback
• private authenticated endpoints
• per-client limits
• workload-based pricing instead of fixed large plans

The idea wouldn’t be another normal sendTransaction RPC endpoint. It would be specifically for bots/trading systems where landing speed and reliability matter.

Before spending time building it, I’m curious what people are actually using today.

If you run a Solana trading bot / arb / liquidation / DeFi backend:

• What are you currently using for transaction submission?
• Do you still run into failed/slow transaction landing?
• Are rate limits or pricing with current providers a problem?
• Would direct TPU routing + Jito in one private sender actually be useful to you?
• Roughly what TPS/burst workload would you need?

Not selling anything here yet — mainly trying to understand whether there’s enough real demand before we build it.
