How to Track Crypto Wallets Across Multiple Blockchains with Nansen: The Ultimate Crypto Wallet Tracker Guide

Tracking crypto wallets across multiple blockchains is essential for investors, traders, and analysts seeking comprehensive insights into asset movements, DeFi positions, and market trends. Nansen provides advanced tools to monitor wallets seamlessly across multiple blockchains and protocols, including Ethereum, Solana, Bitcoin, and layer-2 networks like Arbitrum and Polygon.

Below is a detailed guide to leveraging Nansen’s features for multi-chain wallet tracking.

Key Features of Nansen for Multi-Chain Wallet Tracking

1. Multi-Chain Portfolio Aggregation

Nansen supports 18+ blockchains and 140+ DeFi protocols, allowing users to:

• Track wallet balances, token holdings, and NFT collections across EVM and non-EVM chains (e.g., Solana, Cosmos).
• View aggregated transaction histories in a single dashboard.
• Monitor DeFi positions (e.g., liquidity pools, staking) and NFT holdings across platforms like Uniswap, Aave, and OpenSea.

2. Smart Money Wallet Tracking

Nansen identifies and labels Smart Money wallets (high-performing addresses) across ecosystems. Users can:

• Track whale movements, token swaps, and portfolio changes in real time.
• Set customizable alerts for specific activities (e.g., large ETH transfers, NFT purchases).
• Analyze historical performance metrics to identify market trends.

3. PnL and Transfer Tracking

Nansen’s Profit and Loss (PnL) system automatically updates cost basis across wallets, even when assets are transferred between addresses. For example:

• If 500 AAVE tokens are moved from Wallet X to Wallets Y and Z, Nansen updates the cost basis for each wallet based on transfer prices, ensuring accurate PnL calculations.
• EVM-chain wallets (Ethereum, Polygon) are pooled for unified PnL tracking, while Solana wallets are analyzed separately.

4. Custom Wallet Bundling

Users can create portfolios by bundling any group of addresses, including:

• Personal wallets across multiple chains.
• Whale wallets (e.g., Vitalik Buterin, institutional investors).
• Protocol-owned wallets (e.g., DAO treasuries).
