Node Operator Admission: Pro Delegators (Nuxian Labs) as stVault Professional Operator

Node Operator Application, Pro Delegators (Nuxian Labs)

Pro Delegators (Nuxian Labs SA) is a Swiss-based validator and infrastructure provider. We currently operate across more than 15 networks, including Cosmos, dYdX, Neutron, Osmosis, and Babylon, with roughly $20M in assets under management.

Our setup has always been built around performance and reliability. We run both validator infrastructure and low-latency RPC, and most of our clients are foundations, DAOs, or institutional-facing teams that expect consistent execution rather than experimentation.

On the business side, we don’t expect this to be a slow start. Based on existing relationships, we are confident in sourcing between $5M and $15M in ETH within the first few months, with a path toward $30M+ over a year as we expand through our current pipeline. The focus is not retail distribution, but direct relationships, custodians, and partners already operating in structured environments.

Our interest in stVaults is quite straightforward. We think there is room for operators who approach this from an infrastructure perspective first, not from a purely financial angle. That means stable validator performance, controlled environments, and a setup that can handle load without degrading over time. In parallel, we are aligning with institutional requirements, with SOC2 Type II and ISO 27001 in progress.

From an operational standpoint, we run a bare metal architecture across Europe and APAC, and we are gradually expanding that footprint. We maintain diversity across both execution and consensus clients, and we integrate MEV in a way that remains non-censoring. Monitoring is continuous, with internal tooling built around Prometheus and Grafana to ensure we catch issues early rather than react to them.

In terms of commitments, we tend to stay conservative where it matters. Anti-slashing design is not something we compromise on, and uptime is treated as a baseline expectation, not a target. More broadly, we see our role as contributing to infrastructure that remains usable and resilient as the ecosystem grows.

Overall, our approach is simple. Bring a clean, reliable setup, onboard capital through existing channels, and operate in a way that makes sense for users who care more about consistency than narratives.

Hi! Thanks for applying, it’s great to see you moving forward with onboarding as a stVaults Node Operator.

The stVaults Committee has started the assessment process and we’ll keep you updated as things progress.

As a delegate of the stVaults Committee, I am posting to confirm that the relevant ET motion establishing Pro Delegators’ status as an stVaults Identified Node Operator has now been enacted.

Following the committee’s assessment of Pro Delegators’ application, Pro Delegators has been assigned to the Basic Identified Operator Category under the stVaults framework, in line with the scope of its application.
