Rotki is an open-source portfolio manager and crypto accounting tool designed with privacy in mind. Unlike most tracking applications, Rotki is self-hosted: your financial data is stored locally encrypted and never passes through a third-party server. You retain full ownership of your transaction history, balances, and reports.

The application aggregates your assets from numerous sources: exchanges (via read-only API), multi-chain wallets (Bitcoin, Ethereum, and EVM networks), DeFi protocols, NFTs, as well as your fiat and bank accounts. The result is a unified wealth view, with historical valuation and performance tracking.

On the accounting side, Rotki automatically calculates capital gains, generates tax reports for export, and maintains a complete, auditable history of your operations — a valuable asset during tax season. It is the reference tool for those who want to seriously track their digital wealth without sacrificing their privacy.
