How Nansen Powers Onchain Intelligence Across 500M+ Wallets & 30+ Chains

Nansen is an agentic trading platform that brings onchain analytics and execution, allowing investors to trade everything onchain with AI. Powered by 500 million labeled addresses with real-time data across major networks, Nansen helps investors, funds, and protocols turn complex onchain activity into actionable insights, providing visibility into market movements, wallet activity, and capital flows - right alongside trading. Its AI-powered features enable users to discover opportunities, execute trades, and manage portfolios through a single platform more efficiently.

In 2026, Nansen expanded into active trading execution across Hyperliquid, Solana, and Base, while continuing to add support for emerging networks such as Robinhood Chain. CoinGecko API supports this expansion by giving Nansen consistent access to real-time and historical market data across both established and newly launched networks.

Key Metrics at a Glance

• CoinGecko delivers price and market data across the 30+ blockchains Nansen tracks, covering assets traded on centralized exchanges and long-tail onchain tokens.

• CoinGecko API's data powers key Nansen features, including Smart Money, Portfolio, and PnL, providing the pricing foundation users rely on to analyze opportunities and make trading decisions.

• Nansen added support for Robinhood Chain within one day, enabled by CoinGecko’s ready coverage of new networks, helping the team move quickly when new market demand emerges.

The Challenge: Scaling Onchain Intelligence Across Multiple Chains

Nansen needed timely and reliable market data across more than 30+ chains, covering established assets and long-tail tokens traded exclusively onchain. As the platform expanded from research into live execution, this data needed to support more than static dashboards. It had to provide actionable market context for token discovery, portfolio analysis, Smart Money intelligence, and real-time trading decisions.

Nansen also required historical market data to help users examine performance over time and give Nansen AI deeper context when analyzing onchain activity.

Why Nansen Chose CoinGecko API

CoinGecko gives Nansen a unified market data layer across centralized and decentralized markets. Its coverage of major assets, long-tail onchain tokens, and newly launched networks allows Nansen to expand into new chains and product experiences without building separate market data integrations for each one.

CoinGecko’s batched API endpoints also allow Nansen to retrieve data for multiple assets within a single request. Combined with a predictable credit model where one API request consumes one call credit, this helps Nansen manage data retrieval and infrastructure costs efficiently as its asset and chain coverage grows.

While Nansen combines multiple data sources to maintain data quality, CoinGecko remains an integral source for market prices across its products and experiences.

How Nansen Leverages CoinGecko API

CoinGecko market data is integrated across Nansen's core product experiences, powering token screeners, Smart Money intelligence, token pages, Nansen AI, and user portfolios.

Smart Money and Token Screeners

Nansen's Token Screener combines market performance with proprietary signals such as Smart Money flows and trending onchain activity. This allows traders to compare what the market is doing with the wallets and entities driving that activity.

The /coins/markets endpoint returns prices, market capitalization, fully diluted valuation, trading volume, rankings, and price changes for up to 250 assets in one request. For long-tail tokens traded onchain, Nansen uses /onchain/networks/{network}/tokens/multi/{addresses} to retrieve token and market data across multiple contract addresses efficiently.

Together, these endpoints give Nansen a scalable market data layer for screening established coins and newly active onchain tokens alongside its Smart Money signals.

Detailed Token Pages and Charts

Nansen's detailed token pages bring market performance, onchain activity, and project information into a single view. For assets traded on both CEXs and DEXs, Nansen uses the /coins/{id} endpoint to obtain market data and metadata, while the /coins/{id}/market_chart endpoint provides historical prices, market capitalization, and trading volume for line charts.

For assets exclusively traded onchain, Nansen uses the /onchain/networks/{network}/tokens/{token_address}/ohlcv/{timeframe} endpoint to display candlestick charts of a specific token. The /onchain/networks/{network}/tokens/{address}/info endpoint enriches token pages with names, symbols, logos, websites, descriptions, and social profiles.

Nansen also uses /onchain/tokens/info_recently_updated to efficiently identify recently updated token information and subsequently retrieves new data to keep its product surfaces current.

Onchain Intelligence in Nansen AI

Nansen's agentic experience enables users to interact with onchain data through natural language, including generating live charts and intelligence views within a conversation. When Nansen AI delivers market insights or visualizations, it draws from the same market and onchain price endpoints used across the platform, ensuring consistent data across conversational experiences and core product surfaces.

Portfolio and PnL Valuations

Nansen's Portfolio and PnL experiences require current pricing across the assets held by each user, including long-tail tokens that trade exclusively onchain. For coins traded on CEXs and DEXs, the /simple/price endpoint provides lightweight price lookups across up to 500+ assets in a single API call. For onchain tokens, the /onchain/simple/networks/{network}/token_price/{addresses} endpoint retrieves real-time prices across multiple contract addresses in an efficient batched request.

For historical performance analysis, Nansen uses /coins/{id}/market_chart to access time-series data including historical prices, market caps, and trading volumes, supporting realized and unrealized PnL calculations.

Business Outcomes: Powering Market Context Efficiently Across Nansen

CoinGecko's market data complements Nansen's intelligence layer of more than 500M+ labeled addresses across over 30+ chains. This combination connects prices and market performance with wallet activity, Smart Money flows, known entities, and portfolio positions across Nansen's trading experiences, AI features, and developer tools.

To efficiently scale market context across 30+ chains, Nansen uses an activity-based model that leverages its own onchain activity data to identify actively traded assets, then queries CoinGecko's endpoints for the assets that require updated pricing.

By bringing timely market context and onchain intelligence together, Nansen gives traders a more complete view of what is moving, which wallets are involved, and how those movements affect their portfolios.

What's Next On Nansen's Roadmap

Nansen is deepening its agentic trading infrastructure with AI-powered agents that can surface, analyze, and act on onchain signals. Its roadmap includes execution across more chains and assets, improved Smart Money tracking and trading strategies, and new API and CLI tools for builders.

CoinGecko's price and market data will remain foundational as Nansen extends these capabilities across additional assets and product experiences.
