Use case 1: Automated Token Tracking & Smart Money Analysis

Scenario

A DeFi trading team automated their token discovery and smart money analysis using Nansen's API. They built custom tools that combine multiple data sources to identify promising trading opportunities in real-time.

Problem

• Manual Process: Hours spent cross-referencing multiple dashboards

• Fragmented Data: Token analysis scattered across different platforms

• Slow Decisions: Opportunities missed due to manual analysis delays

• Poor Scalability: Process couldn't handle growing portfolio needs

Solution

The team built an automated system using three core Nansen API endpoints:

1. Token Screener (Link Here) - Find trending tokens

2. Smart Money Netflow (Link Here) - Track institutional buying

3. TGM PnL Leaderboard (Link Here) - Score trader credibility

Step-by-Step Guide

Step 1: Configure Your Token Screener Filters

Start by selecting the chains you want to analyze (e.g., Ethereum, Solana). Apply filters to narrow down your search:

• Set market cap range (min and max) to target tokens with desired liquidity.

• Specify minimum liquidity and number of traders to focus on active, tradable tokens.

• Limit token age to capture new and trending assets.

• Enable “only_smart_money” to prioritize tokens held by sophisticated traders.

• Order results by volume (descending) for immediate visibility on high-activity tokens.

Step 2: Analyze Smart Money Netflow

Use the Smart Money Netflow endpoint to track institutional and expert activity:

• Select your chains.

• Include smart money labels such as “Fund”, “Smart Trader”, and “30D Smart Trader” for targeted analysis.

• Set a minimum market cap and trader count to filter out low-activity tokens.

• Order by net flow over the past 7 days to surface tokens with significant smart money movement.

Step 3: Validate Trader Credibility with TGM PnL Leaderboard

For any token of interest, use the TGM PnL Leaderboard:

• Specify the chain and token address.

• Set your date range for analysis.

• Filter for holders with significant USD value and realized profit.

• Use pagination to manage large datasets.

• This step helps you confirm which traders are consistently profitable, adding confidence to your token selection.
