To understand how SWQoS works, imagine a subway platform at rush hour. The system runs efficiently, but when demand surges, everyone tries to board at once, and not every train can take everyone immediately. That’s similar to how public RPCs in Solana operate during peak activity: a sudden influx of requests competing for limited throughput.
SWQoS introduces order to that process. By prioritizing requests based on validator stake, it ensures the network remains predictable and responsive even under heavy load.
In this article, we’ll explore what makes SWQoS the best approach to Solana RPC access, how it works, and how Everstake scales this technology across the Solana ecosystem.
What Is SWQoS?
Stake-Weighted Quality of Service (SWQoS) is a mechanism that organizes how Solana prioritizes network traffic. In simple terms, it assigns priority to RPC requests based on the stake of the validator sending them. Validators with more stake, and therefore a higher contribution to network security, receive proportionally greater bandwidth and reliability.
This system replaces the previous “first-come, first-served” approach, where all requests competed equally regardless of their importance. With SWQoS, transactions are no longer part of a single congested flow. Instead, they’re processed in clear, weighted lanes, keeping the network fair, efficient, and stable even during heavy load.
As a result, SWQoS has quickly become recognized as the best Stake-Weighted QoS solution for maintaining consistent RPC performance on Solana.
Why Solana Needs Quality-of-Service RPC
Solana has a reputation for speed, but even the quickest elevator will lag if all buttons are pressed at once. This is what happens during token launches or NFT drops: transaction flow spikes, and public RPCs cannot handle the demand. The outcome—failed transactions, delays, and uncertainty—is particularly risky for institutional users, as even short-term network instability can disrupt automated operations, settlement workflows, or compliance reporting.
SWQoS eliminates this unpredictability. It distributes bandwidth proportionally to stake weight, ensuring that essential operations are processed first and mission-critical workloads maintain stability. This marks a major step toward a more predictable, scalable, and institutional-ready Solana experience.
Congestion on Solana RPCs
To understand the value of the best SWQoS models, it is necessary to take a closer look at the problem of network congestion. Solana’s high throughput is impressive, but public RPCs often become the weakest link when network activity spikes.
Public RPC bottlenecks and failed transactions
Public RPCs are a shared resource. They work well under normal conditions, but under load, they quickly become unreliable. This leads to:
- High failure rates (transactions do not reach confirmation).
- Unpredictable performance (from fast responses to critical delays).
- Lack of guarantees (important requests compete with any others).
For institutional or large applications, such uncertainty is no longer a minor inconvenience but a risk that blocks operations and makes it impossible to adhere to standards.
How SWQoS Solana RPC Works
SWQoS makes Solana’s RPC access predictable and transparent. The logic is simple: priority is determined by stake weight, and infrastructure enforces that rule.
Direct RPC connection
Clients are directly connected to the RPC infrastructure SWQoS provides, which uses a stake-based prioritization approach. Since requests are regularly delayed or dropped as traffic increases, this avoids the unpredictability of public endpoints.
The diagram below shows how RPC nodes peer with a validator in the SWQoS model. Rather than simply competing on public endpoints, every RPC connection is established with clear stake-weight rules, and each request is routed with predictable priority.
Virtual stake assignment
A central feature of SWQoS is virtual stake. Institutions aren’t required to run their own validator to enjoy stake-weighted access. Rather, they can be assigned a virtual stake value that determines their position in the queue. This makes the system accessible, while keeping the rules transparent.
Priority routing & deterministic execution
Requests are routed according to their stake weight. That means critical operations don’t get stuck competing on equal terms with every other transaction on the network. That makes the order of execution clear and consistent, an important aspect to have for teams that require reliability.
SLA-backed throughput and uptime
Unlike public RPCs, which work on a best-effort basis, SWQoS provides measurable guarantees. Institutions are given defined service levels for throughput and uptime, supported by monitoring and reporting. This assures teams that their RPC performance will hold steady even when the network is under heavy load.
Pricing Models & Access Tiers
SWQoS makes Solana’s RPC access predictable and transparent. The logic is simple: priority is determined by stake weight, and infrastructure enforces that rule.
Pay-as-you-go
The pay-as-you-go model provides flexibility for teams that wish to test SWQoS in the market without long-term commitments. Each transaction is billed one-off, beginning at 0.0005 SOL. As such, it’s most practical for pilots or low-volume use.
Base SWQoS
This tier guarantees stable access to a system by smaller banks and applications who need to perform on a reliable basis. Clients are guaranteed predictable throughput at a 100k SOL stake weight under most network scenarios.
Advanced SWQoS
At the 300k SOL level, the advanced ones secure higher priority routing and allocation of throughput for institutions. This level is for projects running at scale where you need to avoid interrupting during heavy traffic congestion.
Pro SWQoS
This pro tier is meant for big businesses and mission-critical services. It gives you maximum priority and capacity. By applying a 1M SOL stake weight, clients get access to the highest guarantees.
Custom enterprise packages
For institutions with unique needs — for greater throughput, compliance-related reporting, or bespoke SLAs — Everstake provides tailored package offerings. These are developed in partnership with enterprise teams to accomplish precise operational needs.
SWQoS vs Alternatives
Different RPC access models come with trade-offs. The best SWQoS solutions distinguish themselves through transparency, SLA-backed reliability, and fairness.
Public RPC: congestion & no guarantees
Public RPC is free and widely available but unpredictable. During peak days, congestion leads to failed transactions, long confirmation times, and no service guarantees. It can work for hobby projects, but in institutions, the risks of downtime are high.
Private RPC: limited & opaque
Private RPCs provide a measure of reliability as opposed to public endpoints but tend to be less transparent. While institutions sometimes pay for access, they are still left with no insight into how requests are prioritized or what service level guarantees they have.
SWQoS: SLA-backed stake-weighted fast lane
Combines accessibility with performance transparency. Requests are prioritized by stake weight, backed by SLAs, and monitored for uptime, creating the best Stake-Weighted QoS system for Solana institutions.
Helius SWQoS vs Everstake SWQoS
Helius also implemented SWQoS, showing how fast the model is gaining adoption. Everstake’s SWQoS, however, extends the concept with enterprise-grade reliability, certifications, and support.
