FAQ - Staked Connection
Q. How can I enable QoS?
You can enable QoS through two available methods:
- Monthly Subscription: Paid in Euros (100 EUR/month = 100 SOL QoS)
- elSOL Staking: Each 1 elSOL staked equals 1 SOL QoS
For further details, please contact us on the official Discord.

Q. Transactions on my dedicated node have a low success rate
Transaction success rates and speed are significantly affected by a mechanism called QoS (Quality of Service). We offer QoS specifically for dedicated nodes. For more details, please refer to the pages below or inquire through our official Discord.
Q. What is the latency like?
Latency varies depending on the measurement method and your specific usage environment. Rather than focusing on exact numerical values, it's crucial to ensure that the latency meets your actual operational requirements.
We offer free trials across all our plans, enabling you to test performance directly in your real-world environment. Additionally, we provide easy-to-use tools in TypeScript and Rust for measuring latency. Feel free to utilize these tools alongside your free trial.
Q. Is this RPC (gRPC, Shreds) faster than others?
We encourage you to try our free trial and compare the performance against other services. If you find our service slower, please let us know the specific conditions and competitors you've compared it against via Discord. We will identify the cause and improve the speed further.
We continually work on improving latency based on customer feedback. If you seek the fastest possible endpoint, please share detailed information with us. Providing specific metrics and comparison conditions against competitors allows us to deliver superior performance. This feedback-driven approach has consistently enabled us to enhance our services.
Q. Which plan offers the fastest performance?
Generally, our highest-tier plan provides the fastest performance due to superior CPUs, higher memory capacities, and robust hardware configurations.
We also offer customized solutions if you require even more powerful servers, but our standard plans are designed to deliver optimal price-to-performance ratios.
We are confident in providing world-class performance at every price level. If you find a faster provider within the same price range, please let us know so we can investigate and make improvements.
Q. I'm experiencing high latency. Why?
Latency increases with distance from the endpoint. We recommend accessing from servers close to the provided endpoint. The fastest environments are available through our Bare-Metal servers and VPS services.
Q. Which is the fastest: WebSockets, gRPC, or Shreds?
Customer feedback consistently indicates the following performance order:
Shreds > gRPC > WebSockets
Please let us know if you experience different results.
Q. I need latency of at least ~400ms or better.
To achieve latency within approximately 400ms, consider these essential points:
-
Realistic Understanding of Ping Values: Ping values indicate ideal conditions and do not reflect actual latency in streaming communications, which typically experience around 5 times the ping latency. For example, a ping of 100ms across continents realistically results in about 500ms of latency. Thus, infrastructure must be established within the same region to achieve ~400ms latency.
- Typical Ping Value Reference:
- Same network: ~0.1ms
- Private Network Interconnect (PNI): ~0.2ms
- Same data center: ~0.3ms
- Same city: ~1ms
- Neighboring country: ~5–10ms
- Intercontinental: ~100–300ms

Avoiding the Pitfall of Average Latency: Solana validators are geographically dispersed globally, and the leader schedule changes randomly with each epoch. Relying on average latency to achieve ~400ms is impractical. Instead, you should precisely track validator schedules in your specific region to identify slots with the lowest latency. To consistently achieve minimal latency, infrastructure across all relevant regions is required. Within the same region, data acquisition can occur in tens of milliseconds, with transmission possible in just a few milliseconds.
-
Tracking the Leader Schedule: Continuously monitor the leader validator schedule for your region using tools such as the Solana Beach API or Solana RPC APIs (
getSlotLeadersandgetClusterNodes). This allows you to identify optimal trading slots effectively.
Q. How can I achieve zero-block (zero-slot) trading?
Successfully achieving zero-block (zero-slot) trading requires more sophisticated strategies, as follows:
-
Identifying Opportunity Zones: Solana validators are distributed globally, and it's physically impossible to achieve optimal latency for every slot. Therefore, track validator leader schedules in the region where your infrastructure is located and identify your optimal opportunity zones. Deploying infrastructure across multiple regions can also be beneficial. Frankfurt, for example, is particularly popular due to its high concentration of validators, leading to more frequent leader selection and thus greater trading opportunities.
-
Implementing Dedicated Nodes: If you struggle to compete, consider deploying dedicated nodes. Shared nodes experience latency due to traffic from other users, and thus are not recommended. Furthermore, placing your dedicated node within the same network as your application significantly reduces network latency and optimizes performance.
Q. Latency isn't what I expected.
Performance can vary based on your chosen programming language. Generally, languages perform in the following order:
Rust > Go > TypeScript (JavaScript) > Python

We strongly recommend using Rust if you're aiming for maximum performance.
