Haan Node

Private Solana RPC infrastructure in Frankfurt.
JSON-RPC • WebSocket • Yellowstone gRPC
Workload-based access & pricing.

[Haan Node @HaanNode]

CatalystX just launched their updated website — worth checking out if you’re building around Solana infrastructure.

@CatalystX_SOL operates a Solana mainnet validator from Rotterdam with 220K SOL active stake, 99.9995% average voting uptime, validator-sourced real-time shreds and Staked QUIC / SWQoS forwarding.

Their infrastructure is also the validator-backed layer behind part of our Haan Node stack.

Strong work by the CatalystX team.

[Haan Node @HaanNode]

You don’t need to replace your whole Solana stack.
Use Haan Digital only where you need the edge:
• Private RPC / WebSocket
• Yellowstone gRPC
• SubscribeDeshred
• Staked/SWQoS transaction sender
Frankfurt. Workload-based pricing. 5-day trial.

[Haan Node @HaanNode]

Fast data means nothing if your transaction lands too late.
Haan Digital’s Frankfurt sender uses a validator-backed staked/SWQoS route for latency-sensitive Solana execution.
Keep your current data stack. Change only the sender. Measure what matters: landing, slot, speed, consistency.
5-day trial available.

[Haan Node @HaanNode]

Most Solana infra is sold in fixed tiers.
Haan Digital does it differently: private Frankfurt RPC, Yellowstone, SubscribeDeshred & transaction sending, configured around your actual workload.
5-day trial available.

@Lakes_on_motion @CatalystX_SOL Fair point, although we already linked their website directly in the post so people can verify the validator information themselves there.

Good point. Using the expected slot start from the leader schedule as the baseline should separate shred arrival latency from confirmation delay much more cleanly.

We’ll rerun the measurement that way — first shred arrival vs expected slot start — and keep optimistic confirmation as a separate metric. That should give us a much cleaner view of the actual raw-shred advantage.

[Haan Node @HaanNode]

Solana builders — we just upgraded Haan Digital’s Frankfurt stack with staked/SWQoS transaction routing + direct validator-backed raw shreds.

Private RPC, Yellowstone gRPC, WebSockets and workload-based provisioning.

Looking for a few serious builders to benchmark the stack.

First 2 weeks free.
DM me if you want to test it.

[Haan Node @HaanNode]

Yeah, that’s likely what we’re seeing.

Our measurement is firstShredReceived → optimisticConfirmation, so a larger gap on busier blocks doesn’t necessarily mean the shreds themselves arrived faster — it can also mean optimistic confirmation took longer under heavier load.

The 300-slot sample showed a positive correlation (~0.34) between block tx count and that head-start window, but that’s correlation, not proof of the exact cause.

To separate the two properly we’d need to measure shred arrival timing and confirmation delay independently.

Building faster Solana infrastructure with @CatalystX_SOL.

Haan Node combines our private Frankfurt RPC/Yellowstone stack with CatalystX validator-backed raw shreds, with SWQoS transaction forwarding as the next layer.

Workload-based instead of fixed tiers, and 2-week free trials for builders who want to benchmark it.

DMs open.

[Haan Node @HaanNode]

We tested this properly with a larger 300-slot sample.

The head start actually held up well as block activity increased:

Quietest 25%: 356 ms avg
Busiest 25%: 404 ms avg
Busiest 10%: 420 ms avg
Hottest blocks in the sample reached up to 2,526 transactions

So in this run the raw-shred advantage didn’t shrink under higher block load — the busiest 25% actually showed about 48 ms more head start than the quietest 25%.

It’s not a synthetic launch stress test, but across naturally busier slots the feed held up very well.

[CatalystX | Solana Validator| IBRL/acc @CatalystX_SOL]

Today we’re excited to announce the integration of the CatalystX validator with @HaanNode’s private Solana infrastructure in Frankfurt.

This integration combines direct validator-backed raw shred delivery with Haan Node’s workload-specific infrastructure, including Private RPC, Yellowstone gRPC, WebSockets, Jito and TPU transaction sending.

The goal is simple: give Solana builders a more direct, flexible and customizable infrastructure path than a generic shared RPC platform.

CatalystX and Haan Node are working together to make Solana faster to build on, easier to benchmark and better equipped for serious workloads.

Stake-weighted transaction forwarding is the next phase.

Builders interested in testing the stack can DM @HaanNode. Two-week trials are available.

[South 3rd Ventures | IBRL/acc @S3rdVentures]

S3V is proud to support the integration of the CatalystX validator with @HaanNode’s Frankfurt-based Solana infrastructure.

The partnership brings together validator-backed data delivery and private, workload-based infrastructure for builders who need more than a one-size-fits-all RPC plan.

With direct operator access, customizable routing, filters and capacity, Haan Node can adapt its infrastructure around each client’s actual workload.

This is the kind of collaboration that helps strengthen the Solana ecosystem: practical infrastructure, closer cooperation and better tools for serious builders.

If you’re building latency-sensitive applications, trading systems or developer tooling on Solana, contact @HaanNode to benchmark the stack. Two-week trials are available.

[Haan Node @HaanNode]

@S3rdVentures Really appreciate the support. We’re excited about what this partnership can bring for Solana builders and looking forward to building something strong and long-term together.

[Haan Node @HaanNode]

@CatalystX_SOL Proud to be building this together. The validator-backed shred integration is a big step for Haan Digital, and we’re looking forward to pushing the stack further and hopefully doing a lot of good business together.

[Haan Node @HaanNode]

@AnarchyAlchemis If you want to test it yourself on your own workload, we can give you a 2-week free trial before anything is paid.

Just let me know and I can send you our Discord invite so you can get set up and benchmark it yourself.

[Haan Node @HaanNode]

Big milestone for Haan Digital.

We’ve now integrated direct shred delivery from a staked Solana validator into our Frankfurt infrastructure, and the realtime data path is noticeably faster.

Next up: SWQoS transaction forwarding.

The goal is simple: faster data in, stronger transaction delivery out.

We’re still growing, but this is exactly the direction we want Haan Digital to move in.

If you’re building latency-sensitive workloads on Solana and want to benchmark our setup, DM me. 2-week trials available.

Haan Digital is starting to feel more established.

Our private Solana infrastructure in Frankfurt keeps growing, we’re getting more real workloads on the server, and we’re becoming increasingly comfortable operating in the Solana ecosystem.

The focus now is long term: keep growing, keep improving the infrastructure, add more clients and continue building Haan Digital step by step.

If you’re building on Solana and need Private RPC, Yellowstone gRPC, Jito, WebSocket or TPU Transaction Sender, send me a DM.

New builders and teams are always welcome in the Haan Digital community.

[Haan Node @HaanNode]

Solana builders: are you actually using everything in your RPC plan?

A lot of workloads don’t need huge fixed packages.

Sometimes it’s just:
• 5–10 RPC RPS
• 1 Yellowstone stream
• a few filters
• low transaction volume
At Haan Digital we price around the actual workload, not fixed tiers.
Private Solana infra in Frankfurt:
• JSON-RPC / WebSocket
• Yellowstone gRPC
• SubscribeDeshred
• Transaction Sender

I’m looking for a few more real workloads to test against the stack.
If you’re building a bot, wallet, trading app, indexer or other Solana app and you care about RPC limits, realtime data or transaction landing, DM me.

[Haan Node @HaanNode]

@winniefrom1926 Saw you're building on Solana for the October 14 launch. We run private Solana infrastructure in Frankfurt — Yellowstone gRPC, low-latency RPC and transaction sending. Curious what infra stack you're planning to use for launch?
