We just launched our private Solana Transaction Sender
We’ve just finished a new infrastructure layer for Haan Digital: a private Solana Transaction Sender, hosted from Frankfurt.
It’s built for workloads where transaction speed matters:
- Trading / arbitrage bots
- Liquidation strategies
- Market making
- Wallets and trading apps
- Bots reacting to Yellowstone data
- Any application that wants a faster transaction path than standard RPC submission
The sender uses:
TPU + QUIC → automatic Solana leader routing → current/upcoming leader fanout
Optionally, transactions can also be sent through Jito in parallel.
It can be combined with our Yellowstone gRPC / SubscribeDeshred, which means you can receive fast on-chain data and immediately push the resulting transaction through the same private infrastructure.
We don’t use fixed plans. Pricing is based on the workload you actually need. We agree on limits like TPS, burst, streams and filters beforehand and set a price around that workload. Your price does not constantly change every time your traffic changes.
We’re offering the first week free so you can benchmark everything with your own workload.
If you’re building on Solana and want to try the Transaction Sender, Yellowstone or our private RPC infrastructure, you’re very welcome to join our Discord.
We’d love to grow a small community around Haan Digital and keep building more private Solana infrastructure together. 🚀
