Portfolio tracker
The crypto portfolio tracker that does your tax.
Track Bitcoin, Ethereum, and Solana wallets alongside your exchange accounts. Watch your holdings move over time. Generate compliant tax reports when filing season hits. All from one place, no account required to start.
No signup. Works offline-first.
Every wallet in one view
Add an xpub, an Ethereum address, a Solana address, or an exchange API key. Balances, prices, and transactions land in one dashboard.
Value over time, in your unit
Plot your stack against the price line. Switch between USD, EUR, SEK, GBP, BTC, and sats on the fly. The chart adjusts. Your numbers stay correct.
Tax export, same tool
Swedish K4 ready today. German Anlage SO in build. The data already flows through the cost-basis engine, so the report is one click away when you need it.
What's different
Local-first by default
Try the whole tool without an account. Your wallet addresses live on your device, never our server. Sign in later if you want cross-device sync. Stay anonymous if you don't.
Bitcoin-native units
Switch the whole interface into BTC or sats with one tap. Stack-tracking without fiat-first noise.
Multi-chain, multi-exchange
Bitcoin xpubs and bare addresses, EVM addresses (Ethereum + Polygon), Solana addresses, plus exchange API keys. One total. One chart. One tax export.
Reference rates you can defend
Daily fixings sourced directly from each jurisdiction's reference authority: the Swedish Riksbank for SEK, the European Central Bank for EUR / GBP / cross-pairs. Audit friendly.
Track your portfolio without giving up your keys.
Watch-only, read-only, on-device. No custody, no surprise emails.
