An often-overlooked aspect of Nansen is its free dashboards and tools that provide a wealth of insights for anyone actively participating in or monitoring the cryptocurrency landscape. These insights span various areas, including NFTs, portfolio tracking, Layer-1/Layer-2 performances, and more.
In this article, I will highlight five on-chain insights that can be gleaned from Nansen's free dashboards and tools, helping you better understand the ever-changing crypto landscape.
Crypto and DeFi portfolio tracking
As the web3 space becomes increasingly multichain and DeFi continues to gain prominence, portfolio tracking has become more complex. To track token holdings, DeFi positions, and transactions across multiple chains and wallets, users often need to use multiple platforms and have many tabs open.
However, with Nansen Portfolio, you can bundle multiple wallets and track holdings and DeFi positions across 47 chains and over 400 protocols. The 47 chains include but are not limited to Ethereum, Solana, Arbitrum, Polygon, BNB Chain, Bitcoin, Cosmos and Harmony. This makes it easy to monitor the crypto portfolio of any address, not just your own.

On top of tracking holdings and staking positions, you can also view transactions on multiple chains across all the wallets in the bundle on the transactions tab. For the transactions tab, we have support for 11 chains and are working towards bringing it up to par with the overall product.
List of chains supported in the transactions tab: Ethereum, BNB Chain, Polygon, Avalanche, Fantom, Arbitrum, Aurora, Moonbeam, Cronos, Moonriver, Optimism.

Understanding the state of the NFT market
The NFT market has been extensively covered in the past two years, but gaining an accurate understanding of its state requires more than just analyzing trading volume and floor prices. To get a holistic view of the market, you need to factor in other key data points into your analysis, all of which can be found on Nansen’s NFT trends dashboard.
- Does the data filter out wash trading activity?
- Number of active wallets
- Number of sales
- Percentage of sales that were accepted bids
- Number of new buyers and returning buyers
- Number of active projects across

Layer-1/Layer-2 activity and growth metrics
On-chain metrics are vital to understanding the types of activity on various blockchain ecosystems and their overall adoption and growth. Nansen’s Chain Paradise offers an overview of key metrics of EVM chains supported on the platform.

You can dive deeper into specific ecosystems for all the chains that Nansen supports and track important data points such as:
- Daily active addresses
- Daily transaction
- 7D and all-time number of users by entity
- 7D and all-time number of transactions by entity
- Smart contracts deployed
- Performance vs ETH
Link to individual dashboards: Arbitrum, Avalanche (C-Chain), BNB Chain, Celo, Ethereum, Fantom, Optimism, Polygon, Ronin, Solana, Terra. We’re constantly integrating more chains and if there’s a chain that you’re interested in, let us know!

Note: The amount of data shown and the layout of the dashboards may vary for different chains. We’re working on bringing every dashboard to parity with our Arbitrum, BNB Chain, Ethereum, and Polygon dashboards.
Gas prices, top spenders and consumers
Gas prices indicate the activity level at a given moment on a chain. Analyzing spikes in the median gas price can lead to the discovery of investment opportunities such as a new NFT launch or a surge in DEX trades. Monitoring gas prices also allows you to get a sense of the optimal time to make transactions to avoid paying high fees. Nansen’s gas tracker dashboards (ETH, BNB Chain, Arbitrum and Polygon) offer a comprehensive overview gas prices, top gas spenders and consumers across various timeframes.
The “Median Gas Price” chart allows you to track the median gas price on the respective chains over the last 24 hours with 5-minute intervals

Gas consumer and spender tables highlight the top gas consumers and spenders across three timeframes - 1 Hour, 24 Hours, and 7 days, on both an address and entity level.

You can also monitor the market share of various entities’ activity on a network over time. The “Share of Gas Fees of Top 20 Gas Consumer Entities” chart acts as a high-level overview of what users are doing on the network and monitoring this gives you a sense of how particular sectors in an ecosystem are doing.

Note: We only have gas trackers for ETH, BNB Chain, Arbitrum and Polygon and are working to have one for every chain that we support.
Track Exchange Holdings
Multiple exchanges have leveraged Nansen Portfolio’s extensive chain coverage to offer the public a view of their customers' on-chain holdings.

These pages offer aggregated views of the exchanges holdings across multiple wallets and the 47 chains that Nansen Portfolio has support for. The FTX saga highlighted the importance of transparency among centralized exchanges and these pages help shed light on the health and solvency of these exchanges.

Bonus: Shanghai Upgrade, Arbitrum Airdrop, zkSync Dashboards
Occasionally, public dashboards covering key events or protocols are released on Nansen Query. These dashboards provide interesting insights and data points on the events or protocols they cover.
Wrapping up
Whether you’re interested in NFTs, DeFi, or the development of various blockchain ecosystems, Nansen’s free dashboards allow you to gain useful insights on things that matter to you. As the industry grows, utilizing on-chain data and analytics tools becomes vital to finding opportunities and doing due diligence.
