Why AllenHark 0 Slot?
Only QUIC Provider
We are the only infrastructure provider in the market offering Solana transaction sending via QUIC protocol, making us the fastest option available.
Microsecond Latency
Direct QUIC connections to leader TPU achieve sub-millisecond transaction propagation times in Frankfurt region.
Pay Per Transaction
Cost-effective 0.001 SOL per transaction model. Only pay for what you use, no monthly minimums.
Frankfurt Region Latency Comparison
Real-world transaction propagation times from Frankfurt to Solana validators. QUIC's multiplexing and 0-RTT handshake deliver unmatched speed.
| Provider | Protocol | Avg Latency | P99 Latency | Same Block % |
|---|---|---|---|---|
| AllenHark 0 Slot | QUIC | 0.1ms | 0.2ms | 99.8% |
| Premium RPC (Co-located) | HTTPS | ~1-2 ms | ~3-5 ms | 95-97% |
| Standard RPC | HTTPS | ~5-10 ms | ~15-25 ms | 85-90% |
| Public RPC | HTTPS | ~50-100 ms | ~200-500 ms | 60-75% |
Why QUIC is Faster
QUIC eliminates TCP's 3-way handshake with 0-RTT connection establishment, prevents head-of-line blocking through independent stream multiplexing, and provides built-in congestion control optimized for blockchain workloads. This results in consistent sub-millisecond transaction propagation to the leader's TPU.
Technical Advantages
High TPS Capacity
Our infrastructure handles 50,000+ transactions per second with QUIC's efficient multiplexing, far exceeding traditional HTTPS RPC limitations.
Largest SWQoS Pool
Stake-Weighted Quality of Service ensures your transactions are prioritized through our extensive validator stake pool, maximizing inclusion rates.
Direct TPU Connection
Bypass traditional RPC overhead with direct QUIC streams to the leader's Transaction Processing Unit, eliminating intermediary hops.
Cost-Per-Transaction
Pay only 0.001 SOL per transaction. No monthly fees, no rate limits, no hidden costs. Perfect for high-frequency trading and arbitrage bots.
Frequently Asked Questions
Q: What makes AllenHark the only QUIC provider?
A: We have built custom infrastructure that directly integrates with Solana's QUIC-based TPU ingestion layer. While other providers use standard HTTPS RPC, we send transactions using the same QUIC protocol that validators use internally, eliminating protocol conversion overhead.
Q: How does 0 Slot landing work?
A: "0 Slot" means your transaction lands in the current block being produced, not the next one. Our sub-millisecond QUIC connections ensure transactions reach the leader's TPU fast enough to be included in the active slot, maximizing your execution speed for time-sensitive operations like arbitrage and sniping.
Q: What is the pricing model?
A: We charge 0.001 SOL per transaction sent through our QUIC infrastructure. This is a pure pay-per-use model with no monthly minimums, setup fees, or rate limits. You only pay for successful transaction submissions.
Q: Can I use this with my existing trading bot?
A: Yes! Our service is compatible with standard Solana transaction formats. Simply point your bot to our QUIC endpoint instead of a traditional RPC, and you'll immediately benefit from microsecond latency. Integration takes minutes, not hours.
Q: How does this relate to AllenHark Relay?
A: AllenHark Relay is our comprehensive transaction relay service that includes QUIC-based sending as its core feature. 0 Slot specifically refers to the same-block landing capability enabled by our QUIC infrastructure. Learn more about AllenHark Relay.
