## FAQ: Frequently Asked Questions

**Q1: Is Zerion free to use?**
A: Yes, Zerion's portfolio tracking is completely free for individual users. The company monetizes through its built-in swap feature (small fee), premium API access for developers, and the Zerion Wallet's built-in trading functionality.

**Q2: Can Zerion steal my funds?**
A: No. Zerion is a **read-only** portfolio tracker. It cannot initiate transactions or move your funds. You only sign authentication messages, not transactions. However, always verify you're on the official website and review any signatures carefully.

**Q3: Which blockchains does Zerion support?**
A: As of 2026, Zerion supports Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Chain, Avalanche, Fantom, Gnosis Chain, zkSync, Scroll, Linea, and Mantle — with new chains added regularly based on user demand.

**Q4: How does Zerion calculate portfolio values?**
A: Zerion aggregates price data from multiple decentralized exchanges and oracle providers. Token values are calculated using real-time DEX liquidity data, while NFT valuations use floor prices and machine-learning-based price estimates.

**Q5: Is there a limit to how many wallets I can track?**
A: No, you can track an unlimited number of wallets through Zerion's watchlist feature. This is particularly useful for fund managers, DAO treasuries, and power users who manage multiple addresses.

**Q6: Can I use Zerion for tax reporting?**
A: Yes, Zerion offers CSV export functionality that is compatible with most crypto tax software including Koinly, CoinTracker, TokenTax, and TurboTax. The export includes timestamps, cost basis, proceeds, and gas fees.

**Q7: What's the difference between Zerion web app and Zerion Wallet?**
A: The Zerion web app is a portfolio tracker that connects to external wallets. Zerion Wallet is a native mobile wallet app with built-in portfolio tracking, swap functionality, and WalletConnect support. Both use the same underlying infrastructure.

**Q8: How does Zerion compare to DeBank?**
A: Both are leading DeFi portfolio trackers. Zerion offers a more polished UI, better mobile experience, and open-source components under MIT license. DeBank has a stronger focus on social features and has its own token. Many power users use both complementarily.
