Is Chainfolio free to use?

Yes, Chainfolio is completely free. It is a browser-native application — no subscription, no freemium tier, and no account required. Simply open the app and start tracking.

Do I need to create an account?

No. Chainfolio has no concept of 'users'. There is no account creation, no email collection, and no KYC. The app runs entirely in your browser with no server-side authentication.

Where is my data stored?

All your data — wallets, transactions, snapshots, and settings — is stored exclusively in your browser's IndexedDB and localStorage. No server ever receives your data. Clearing your browser data permanently deletes it.

What blockchains does Chainfolio support?

Chainfolio has full support for Ethereum and Solana, including native tokens, staking positions, and full transaction history. Smart chain detection automatically classifies transactions (transfers, swaps, stakes, NFTs).

Do I need to connect my wallet?

No. Chainfolio supports watch-only mode — paste any public wallet address to track balances and transactions without any wallet connection. You can also connect via 31 supported browser wallet adapters (Phantom, Solflare, Ledger, and more).

What wallet adapters are supported?

Chainfolio supports 31 Solana wallet adapters including Phantom, Solflare, Coinbase Wallet, Ledger, Trust Wallet, Trezor, MathWallet, Coin98, Nightly, Particle, SafePal, and 20 more. The app only reads the public key — it never accesses private keys.

Do I need API keys or RPC endpoints?

Chainfolio ships with no hardcoded API keys. You provide your own RPC endpoints for Ethereum and Solana (Alchemy, Ankr, Helius, etc.) and optional Etherscan API key for higher rate limits. DexScreener and DeFiLlama are used without API keys.

Does Chainfolio track my analytics or usage?

Absolutely not. Chainfolio has zero telemetry — no Google Analytics, no Mixpanel, no Amplitude, no crash reporters, no cookies sent to third parties. It is architecturally impossible for Chainfolio to observe your usage.

Does Chainfolio have a whale tracking feature?

Yes, Chainfolio includes Whale Watcher – a smart money radar with a pre‑loaded directory of top traders, funds, and founders. Track wallets like Vitalik Buterin, Justin Sun, Wintermute, and high‑PnL anonymous traders with one‑click whale tracking.

Does Chainfolio support background alerts?

Yes, Chainfolio provides serverless background alerts via push notifications for portfolio changes, balance thresholds, token price moves, and RPC health degradation. Runs even when the app is closed via Capacitor Background Runner and Service Workers.

Is there a mobile app for Chainfolio?

Yes, Chainfolio is built with Capacitor and runs as a native iOS/Android app with full access to background sync and push notifications. The UI adapts with sidebar on desktop and intuitive bottom navigation on mobile.

Terms of Service

Last Updated: March 11, 2026

Welcome to Chainfolio (chain-folio.com). By accessing or using the Chainfolio web application, you agree to be bound by these Terms of Service.

1. Description of Service

Chainfolio is a browser-native, local-first portfolio analytics dashboard for on-chain assets. The application runs entirely within your web browser. No personal data is collected by Chainfolio, and no data is transmitted to any Chainfolio server.

Key characteristics:

All core user data is stored exclusively in your browser’s IndexedDB and localStorage.
You may optionally connect personal cloud storage (e.g., Google Drive) to synchronize your local data across devices.
Chainfolio has zero telemetry.
You bring your own API keys and RPC endpoints (BYOK).

2. No Account Required

Chainfolio has no concept of internal “users.” There is no account creation on our end. If you choose to use the cloud synchronization feature, you authenticate directly with your third-party provider (e.g., Google) from your browser.

3. Your Data Responsibility & Cloud Sync

Local Storage: You are solely responsible for backing up your data. Clearing your browser storage without a backup will result in permanent data loss.
Google Drive Synchronization: If you utilize the Google Drive backup feature, you are responsible for maintaining access to your Google account. Chainfolio does not control your Google Drive and cannot recover deleted files or restore lost access to your Google account. By integrating this service, you also agree to Google’s Terms of Service.
Chainfolio cannot recover lost data on your behalf under any circumstances, as we host no databases.

4. Third-Party Services and API Keys

Chainfolio requires you to provide your own RPC endpoint. Chainfolio also fetches publicly available price and DeFi data from DexScreener and DeFiLlama. You are responsible for compliance with the terms of any third-party API provider you use. Chainfolio does not log or transmit your credentials to any external server.
