Chainstack unveils Unstoppable RPC Endpoint at the ETHBelgrade hackathon

In the rapidly evolving world of blockchain technology, hackathons have become the crucibles where innovative solutions are forged. These events draw together the brightest minds in the industry, each team daring to challenge the status quo and elevate the technological landscape. Among these events, the ETHBelgrade hackathon has distinguished itself as a prestigious platform where creativity, innovation, and technological prowess converge.
This year, the event lived up to its reputation, with a remarkable array of teams from across the globe showcasing groundbreaking projects. Each project brought a unique perspective and a fresh approach to the table, attempting to address real-world problems using the transformative potential of blockchain technology.
One of the highlights of this year’s event was a game-changing solution presented by Chainstack. Led by our Product Director Vasily Rudomanov, our team was honored to be among those contributing to the vibrant tapestry of innovation. Our entry, the Unstoppable RPC Endpoint project, aimed to simplify and enhance the Web3 development process.
Tackling the problems faced by traditional RPC endpoints
Traditional RPC endpoints, such as those offered by us at Chainstack, as well as Alchemy and Infura, are limited by their infrastructure, which leads to lower uptime, higher latency, and the lack of custom logic for an RPC endpoint.
Problem

We conceived the Unstoppable RPC Endpoint project to address these issues by aggregating multiple RPC endpoints from different providers, regions, and cloud services. Based on various factors like availability, block height, latency, and serving capacity, our service intelligently redirects requests to the most suitable node.
Intelligent aggregation of multiple RPC endpoints
Our Unstoppable RPC Endpoint solution stands out by intelligently aggregating multiple RPC endpoints from various providers, regions, and cloud services. By assessing different factors like availability, block height, latency, and serving capacity, our service can determine the most optimal node for a given request. This approach ensures that our users enjoy higher uptime, lower latency, and better overall performance.
Idea
Global Load Balancer for multiple RPC endpoints with blackjack and courtesans:
- Health checks
- Load checks
- Block height checks
- Latency checks
And get:
- Instant failover
- Allow list (by IP or Origin)
- Caching
- Universal RPC for both full and archive data behind
Optimal rerouting based on availability, latency, and serving capacity
We understand that the availability, latency, and serving capacity of nodes play a crucial role in creating a seamless Web3 experience. That’s why our Unstoppable RPC Endpoint project has been designed to dynamically reroute requests to the most suitable node based on these factors. This ensures that we maximize the performance and reliability of RPC endpoints, making them truly unstoppable.
Solution
- Leverage Cloudflare Workers’ serverless functions
- Run a middleware layer between an end-user and a set of RPC endpoints
- Detect what RPC endpoints are eligible to participate in load-balanced proxied traffic
- Provide a custom logic how to serve traffic
- Extend functionality for filtering by IP-addressed and HTTP Origin
- Cache requests to minimize latency and utilization of nodes even better
Enhanced security and optimization features
In addition to the innovative aggregation and rerouting mechanisms, we also prioritized advanced security and optimization features when developing our Unstoppable RPC Endpoint project. We’ve incorporated access-list capabilities to whitelist IP addresses or HTTP referrer origin values, custom rate-limiting and throttling parameters, and redirection mechanisms based on the type of data (full or archival). This focus on security and optimization raises the bar for the performance and robustness of RPC endpoints.
Architecture

Commercial white-glove offering
For those who seek a more premium, hands-off experience, we have crafted a commercial white-glove service based on our Unstoppable RPC Endpoint technology. This offering caters to users who prefer a tailored, fully managed solution without the need for in-house technical expertise.
Impact on DApp projects and EVM-compatible chains
Our primary motivation for creating the Unstoppable RPC Endpoint project was to simplify the life of Web3 developers by redesigning traditional RPC endpoints. By offering intelligent aggregation and rerouting to the most suitable nodes, we’re able to help developers focus on building innovative DApps without worrying about the complexities of managing and optimizing RPC endpoints.
Why is it different?

The Unstoppable RPC Endpoint project is poised to be a game-changer for DApp projects and EVM-compatible chains. Our focus on performance, security, and resource optimization has yielded an open-source tool that promises to uplift the Web3 user experience.
We are confident that Unstoppable RPC Endpoint has the power to redefine the future of Web3 development, boosting the efficiency, reliability, and security of RPC interactions. With our steadfast commitment to innovation and refinement, we envision a more streamlined and effective environment for the flourishing of the Web3 community.
Future plans
- Intelligent distributed caching, so the solution will share cached requests between all workers in each region
- Integration with block builders for private transactions implementation (avoid MEV/sandwich/snipping)
- Statistics for analytic firms to show end-users location and used methods
- Securing transactions by validating sender/receiver within databases of malicious actors
- Checking if API methods have proper structure, so no useless/nonsense transactions
“We’re immensely proud to have been recognized at the ETHBelgrade hackathon for our Unstoppable RPC Endpoint project. Our primary motivation was to simplify the life of Web3 developers by redesigning traditional RPC endpoints. By offering intelligent aggregation and rerouting to the most suitable nodes, we’ve not only maximized performance but also enhanced security and optimization features.” Vasily Rudomanov, Product Director at Chainstack, shared.
“This open-sourced tool is a gift to every DApp project and EVM-compatible chain, geared towards enriching the Web3 user experience. Additionally, for those seeking a premium, hands-off solution, we’ve created a commercial white-glove offering based on the same innovative technology. We’re excited to facilitate a smoother, more efficient future for the Web3 community,” he concluded.
