Get actionable insights about your chain. Gain access to real-time data on RPC requests, understand user behavior, and gain actionable insights to improve your network's performance.

  • Global metrics — track billions of requests/month across mainnet and testnet.

  • User-level stats — see compute units spent, request methods used, and per-user behavior.

  • Live dashboards — monitor usage spikes, cache performance, and bootstrap peers in real time.

  • Built-in tooling — no need to set up your own observability stack.

Stop Paying for RPC. Start Earning from It

With Proteus Shield, your RPC costs don't just go down — they can turn into revenue.

  • Volume-based discounts : the more usage, the lower your cost per request.

  • User-funded model : the network pays as usage grows, not you.

  • Overage? Get paid back. If user payments exceed infra costs, Chain.Love can reimburse you.

  • Full-featured by default : updates, feature requests, and premium support are all included.

Why Choose Us

Proteus Shield is a middleware solution that enhances the user experience when interacting with APIs while giving networks greater control over configuration, security, caching, and monetization.

  • RPC Nodes hosting

    Up to 10x cheaper than third-party providers, flexible discount system depending on the network’s load. Users are charged based on real usage.

  • Advanced Security & Rate Limiting

    Protect against DDoS: limits requests per second/per minute/per API key/per user, blocking spam.

    Check our uptime

  • Expose different APIs

    Proxy your RPC nodes, subgraphs, and even your own applications with the ability to configure cache, rate limiting, and monitoring for these endpoints. Deploy subgraphs automatically and query them through the UI playground.

  • Monitoring & Insights

    Get real-time data on RPC requests, understand your users and what they are doing within your network.

Testimonials

We’ve been building Checker Network on and around Protofire services from day one. As our DePIN user base steadily grew beyond 40k nodes, we needed a rock-solid product that supported over 500 JSON-RPC calls per second. In order not to explode our bills, it should have a caching layer on top. And Protoshield is just that! Overall, the team helped us reduce cost by over 60%, through their intelligent caching offering.
