When it comes to blockchain data, clarity is the competitive advantage. Market participants, from hedge funds to protocol teams, are inundated with raw information, struggling to separate signal from noise. Nansen emerged as a response to that chaos: a platform built to make blockchain data not just accessible, but deeply insightful and immediately actionable. Behind its clean dashboards and labeled wallets, however, lies an invisible but critical foundation: infrastructure. That’s where Ankr comes in.

As Nansen evolved into a mission-critical tool for thousands of users seeking real-time blockchain intelligence, its infrastructure demands grew in both complexity and urgency. The platform needed a global, scalable, always-on network to ensure it could deliver insights with speed and precision (regardless of network congestion, user demand, or the expansion of new blockchain ecosystems). Nansen’s vision was clear, but executing it at scale required more than internal engineering muscle. It required an infrastructure partner that could match its ambition. That partner is Ankr.

Nansen’s Role in the Blockchain Ecosystem

To understand why this partnership matters, it helps to grasp what Nansen actually does, and why it’s essential. At its core, Nansen turns raw onchain data into readable narratives. It maps wallet behavior, clusters Smart Money movements, and builds visual interfaces that reveal market sentiment, token velocity, liquidity patterns, and user segmentation. This information isn’t just “nice to have.” It’s foundational for institutional investors making real-time allocation decisions, for developers designing new token incentives, and for researchers decoding emerging market behavior.

This kind of real-time behavioral analysis depends entirely on infrastructure. Nansen’s product must ingest terabytes of data from over 80 blockchains, label and categorize it with precision, and deliver it instantly to users around the world. Every second of latency, every moment of downtime, chips away at the reliability of the insights it delivers. Infrastructure, in this context, is not background—it is the beating heart of the product.

Nansen’s Challenge

As Nansen scaled, three challenges became clear. First was uptime. Nansen’s clients (hedge funds, market makers, token teams) are often making high-stakes decisions in fast-moving environments. If a dashboard goes down or a key data stream lags, it can cost millions. Nansen could not afford infrastructure hiccups. It needed 99.99% uptime, no exceptions.

Second was multi-chain complexity. The blockchain ecosystem isn’t static. Ethereum, Solana, Arbitrum, Base, Cosmos, and dozens more networks evolve in real time. Nansen’s value depends on its ability to provide unified, real-time insights across them all. That means not just supporting these chains, but integrating them with consistent speed and reliability.

Finally, there was the speed imperative. In onchain trading and research, milliseconds can be the difference between catching a market anomaly or missing it. Whether it’s a whale wallet entering a DEX or a fresh NFT mint gaining traction, users depend on Nansen to know before the rest of the market does. Infrastructure that’s even slightly behind isn’t good enough.

Why Ankr Was the Right Fit

56ms Global Latency

Ankr wasn’t just another RPC provider. It offered something different: our global fiber network with bare-metal node infrastructure designed specifically for high-performance, low-latency, multi-chain use cases. With Ankr’s help, Nansen was able to guarantee fast, uninterrupted data delivery from every major chain. Whether the user was in New York, Singapore, or London, data reached them in under 60 milliseconds.

99.99% Uptime

That level of speed wasn’t theoretical, it was measurable. Real-time dashboards, WebSocket-powered alerts, and Smart Money visualizations were only possible because Ankr provided a rock-solid foundation. The infrastructure was resilient even during network congestion or regional outages, ensuring Nansen's services remained online and accurate when users needed them most.

80+ Supported Blockchains

Ankr’s infrastructure also gave Nansen something harder to quantify but equally essential: the confidence to expand. With over 80 blockchains supported, Ankr allowed Nansen to move into emerging ecosystems without hesitation. New rollups, alt-L1s, and modular networks weren’t viewed as challenges, they were opportunities. Nansen knew it had the infrastructure to match its pace of innovation.

What the Partnership Enabled

The results of this collaboration became visible not just in the product’s performance, but in how Nansen was able to evolve. Its dashboards became faster and more stable. Its customer base expanded confidently into new markets. New features, like the Nansen Points program and a powerful new API for programmatic access to Smart Money trends, became possible because the platform no longer had to worry about the infrastructure layer. That burden was lifted by Ankr.

Even more importantly, the data itself became more trustworthy. In a field where misinformation and latency can distort markets, having infrastructure you can trust means delivering insights that others can act on with conviction. Traders moved faster. Builders deployed smarter. Nansen became a tool not just for seeing the chain—but for understanding it deeply and responding to it immediately.

Looking Ahead

In an era where data is the foundation of every decision, the partnership between Ankr and Nansen is a glimpse into what the future of onchain intelligence looks like. It’s not just about dashboards and RPC calls. It’s about building systems that remove the noise, surface the signal, and do it at the speed of the chain itself.

Ankr didn’t just help Nansen scale. It helped Nansen lead.
