By integrating the Nansen API, a cross-chain DeFi wallet platform dramatically improved its ability to track Smart Money flows, analyze wallet behaviors, and surface high-performing tokens—identifying 126 tokens with >100% gains and uncovering accumulation patterns that preceded major price surges. The API became a foundational analytics layer, streamlining research workflows and enabling internal and partner-facing tools powered by real-time, structured onchain intelligence.

Tracks Smart Money flows across L1s, L2s, and app chains

Enables high-fidelity token research and wallet profiling

Supports both internal analytics and partner-facing features

“The Nansen API is incredibly rich, well-structured, and purpose-built for the use cases we care about — from tracking flows, to tagging entities, to enabling data-driven insights that just aren’t available elsewhere.”

— Matthew K, Finance & Business Analyst

The Problem

As an analyst at a cross-chain DeFi wallet platform, Matthew’s role involves surfacing accurate, actionable insights from a complex, multi-layered onchain environment. With dozens of L1s, rollups, and app chains in play, they needed a reliable source of token- and wallet-level intelligence that could scale.

“We wanted to remove the guesswork from understanding token and wallet behaviors… and Nansen seemed uniquely qualified.”

Prior to integrating Nansen, the team faced challenges around:

• Inconsistent wallet labeling

• Limited visibility into token flows

• Manual scraping of dashboards for wallet research

• Time-consuming internal data prep

They needed a structured solution that supported both deep-dive research and real-time programmatic workflows.

The Solution

Using the Nansen API, Matthew and his team built out:

• Custom dashboards for token and wallet research

• Partner-facing APIs enriched with smart money context

• Internal tagging systems for labeling wallet behavior patterns

They rely on endpoints including:

• Address Profiler

• Smart Money Tags and Labels

• Flow aggregations

• PnL and MEV exposure stats

“We use Nansen’s API to identify behaviors and groupings across wallet clusters. We also love how customizable and composable the queries are.”

These integrations enabled faster analysis, clearer narratives, and more impactful outputs across research and product.

The API enables the team to precisely identify smart wallet entry and exit timing, often surfacing coordinated accumulation patterns ahead of significant price action.

Using Nansen's DEX Trades API, Matthew identified 126 tokens that gained >100% during smart money trading periods (Sept-Nov 2025), with 78 tokens exceeding $500K market caps. Our chronological analysis revealed exceptional opportunities like SOCIAL-ANALYZER (+12,205%) and DEXTF (+10,937%) on Base chain, with smart money achieving 1000%+ returns in just 15-20 days on average.

With the DEX Trades API, the team uncovered a repeatable pattern: high-performing tokens typically show clusters of coordinated accumulation by smart wallets shortly before major price surges.

The Results

The team has seen strong results since rolling out the Nansen API:

• Faster token research cycles

• Richer insights into smart money behavior

• Streamlined internal workflows

• Stronger data confidence across product and research teams

“It’s dramatically improved internal coordination — we’re now aligned across teams on a shared understanding of wallet and token activity.”

With Nansen’s data in place, it supports everything from:

• Advanced wallet filtering

• Conviction-based token scoring
  Partner API enrichment

• Strategic research reports
  
  

Quantifiable Token Intelligence

• Identified 126 tokens that gained over 100% by analyzing smart money inflows

• Notable outperformers: SOCIAL-ANALYZER (+12,205%) and DEXTF (+10,937%) on Base

• Observed holding pattern: optimal window of 15–20 days for 1000%+ returns

“With Nansen’s API, we can systematically detect accumulation phases and uncover trading patterns that often signal large price movements.”

Summary

For Matthew, the Nansen API unlocked a new layer of research velocity and quality — moving from scattered dashboards to structured, filterable, high-signal data. Whether analyzing flows, tagging wallets, or powering internal tooling, Nansen has become a core part of how their team interprets the onchain landscape.

“It’s a foundational analytics layer for how we interpret the onchain world — and we’d recommend it to any team building serious Web3 infrastructure.”
