Privacy-first, free forever, zero backend — here's exactly how it all works.
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.
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.
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.
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).
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).
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.
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.
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.
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.
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.
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.
