In crypto, reliability is everything. One delayed request can mean a missed opportunity, or worse — lost trust. For platforms like CEX.IO, which serve millions of users around the globe, every single call to the blockchain matters.

That’s why the team went looking for a partner who could deliver speed and scale, without artificial limits holding them back. And that search led them to NOWNodes.

A Quick Look at CEX.IO

CEX.IO has been around since 2013, back when crypto was still in its early days. They started with GHash.io, a mining pool that quickly became the world’s largest. But instead of chasing dominance, they voluntarily scaled back when it got too close to controlling Bitcoin’s hashrate.

That decision says a lot about who they are: focused on security, fairness, and accessibility. Over time, they’ve grown into a full ecosystem of services — even becoming the first exchange where people could buy Bitcoin with a credit card.

Today, their mission is to bridge the gap between CeFi and DeFi, helping more people join the crypto economy without sacrificing safety or trust.

The RPS Problem

But even the strongest platforms face technical hurdles. For CEX.IO, the big challenge was handling huge amounts of RPC traffic. When you’re dealing with millions of blockchain requests per second, traditional infrastructure often just can’t keep up.

Most providers impose strict requests-per-second (RPS) limits. That’s fine for small projects, but for a global exchange, those limits quickly turn into roadblocks. As the CEX.IO team explained:

“One of the main reasons was the absence of a requests-per-second limit, which is a common restriction among other providers and often insufficient for our needs.”

In other words: when every request matters, you can’t afford to have caps.

Why NOWNodes Was the Right Fit

This is where NOWNodes came in. Unlike other providers, NOWNodes doesn’t limit RPS. That freedom was the deal-breaker for CEX.IO, but it wasn’t the only thing that stood out.

• Wide support for different networks, including Base and XDC.

• A responsive support team that helped smooth over the small bumps at the start.

• Flexibility to act both as a backup and, for some chains, as the main RPC provider.

What began as a backup solution has become a core part of CEX.IO’s infrastructure.

The Results

With NOWNodes in place, CEX.IO has seen uptime improve and resources optimized. Instead of investing heavily in maintaining every node themselves, they can rely on NOWNodes to deliver stability — and focus their energy on growth.

As they put it: “Since integrating NOWNodes, we’ve seen an improvement in application uptime… NOWNodes enhanced the overall reliability of our blockchain nodes, helping us deliver a more stable experience to our users.”

For traders and users, that translates into smoother transactions, stronger trust, and a platform that simply works.

Final Thoughts

At the end of the day, the partnership between CEX.IO and NOWNodes is about more than infrastructure. It’s about showing what’s possible when two teams combine their strengths: one bringing a decade of innovation in crypto services, the other offering flexible, reliable blockchain access without limits.

Because in crypto, every request matters. And together, CEX.IO and NOWNodes make sure not a single one gets left behind.
