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 currently has full support for Solana, including native SOL, SPL tokens, staking positions (native + Marinade mSOL), and full transaction history. Ethereum and Polkadot adapters are scaffolded for future expansion.

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 Solana RPC endpoint (Alchemy, Ankr, Helius, GetBlock, Chainstack, or any custom endpoint) via the onboarding wizard. 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.
