How Bitquery Powers Every Live Price on Nansen

The Challenge

Nansen isn't just an analytics dashboard - it's now a trading platform, the kind that demands precision, speed, and breadth across every major blockchain. When you're serving professional traders, stale prices or missing chains aren't acceptable. Every chart, every candlestick, every position tracker has to be correct and up to date.

Nansen went looking for one thing: enterprise-scale, production-grade, cross-chain live prices, OHLCV and trade data that could feed directly into their TradingView charts and app without requiring them to first build a real-time data infrastructure team.

What They Needed

Thousands of websockets open at once. A trading platform doesn't poll. Every active user is a live conenction to Bitquery’s servers. At Nansen's scale, that's thousands of sockets held open at the same time.

Prices within a second of the on-chain event. Not near real-time. Not eventually consistent. When a swap lands, it has to hit the user's chart in under a second.

Accuracy and reliability they can trust. Nansen's trading apps require reliable, low-latency OHLCV (Open, High, Low, Close, Volume) feeds that stay responsive under load. The feed had to be reliable enough to be the single source of truth.

Every major DEX and launchpad from day one. Nansen's platform spans the ecosystem - Ethereum, Solana, Arbitrum, Base, Polygon, and more. Their price data provider has to match that breadth without sacrificing depth on any single chain.

All of it from one provider. Stitching together multiple data sources creates fragile pipelines, inconsistent latency profiles, and endless integration overhead. Nansen needs a single source of truth - a streaming system that delivers real-time prices across every chain their users care about.

They did the work. They evaluated the major on-chain data providers on the market. Each had gaps - subgraph overhead, inconsistent latency, query-only access, thin chain coverage, or fragmentation across multiple providers.

Only Bitquery delivered everything.

The Solution

Bitquery's GraphQL API is the backbone of Nansen's live price infrastructure.

OHLCV price data powering Nansen. Bitquery's OHLCV endpoints feed directly into Nansen's applications, delivering the structured candlestick data professional traders expect - across timeframes from 1-minute bars to monthly charts.

Built for trading-floor concurrency. Live prices across thousands of simultaneous WebSocket subscriptions, updating within a second of the on-chain event.

Every chain, DEX, and launchpad from one pipeline. New pairs get covered as they go live, so users never hit a "we don't track that yet."

P95 holds under load. The endpoints are tuned so the 95th-percentile response stays fast on heavy queries, not just trivial ones.

Custom-built for Nansen's needs. This isn't an off-the-shelf integration. Bitquery tailored their offering specifically around Nansen's architecture and performance requirements.

The Results

• All live prices on Nansen are powered by Bitquery - sole provider, single pipeline, no fallback needed.
• TradingView OHLCV charts at 92ms median latency, P95 under 120ms.
• Thousands of concurrent websockets, stable under live trading load.
• Every major chain, DEX, and launchpad from a single GraphQL endpoint.
• A partnership, not a contract. Nansen gets enterprise level infrastructure and instant support.

"At Nansen, we're building a trading platform that demands high-quality, cross-chain live price data - so when we went looking for the best onchain data available, we did a thorough search of the market. Bitquery came out on top."

"What's kept us there is the team. They're genuinely locked in - they respond instantly, and rather than handing us an off-the-shelf product, they tailored an offering specifically to our needs."

"Whenever we've hit an issue, they jump on it immediately. We recently flagged elevated P95 latency on one of our TradingView OHLCV queries, and their team had us sorted within minutes - down to the exact query parameters."

"We don't think of Bitquery as a vendor. They're a partner. Bitquery now powers all live prices across Nansen."

Why This Matters if You're Building a Trading Platform

The problem Nansen solved is not unique to Nansen.

The data is on-chain. But turning it into production-ready candlesticks, delivered at trading latency, across thousands of connections, accurate enough to run with no fallback, is almost impossibly hard.

Bitquery takes that work off the table. One endpoint streaming real-time trades and prices, shaped to your data model, with no data engineering team between you and launch.

Nansen looked at the major providers and picked Bitquery because it was the only one that did all of it from a single endpoint: cross-chain OHLCV, sub-second streaming, sub-120ms P95, thousands of concurrent sockets, full DEX and launchpad coverage, and a team willing to go the extra mile.

And the result - Bitquery powering all live prices across Nansen - speaks for itself. No dual-sourcing. No fallback providers. One API. Every price. Every chain.
