3,000+ Desktop downloads shaped the product
Double-entry Books that tie out, not a balance tracker
CLI + Server API One binary, self-hosted
Never metered Not by wallet, transaction, or report
One ledger for Bitcoin, Lightning, and Liquid
Native node connections, xpub and descriptor scans, and CSV imports
Three problems you know too well
-
You're paying tax on a sale you never made.
A move between your own wallets gets booked as a sale. You're taxed on a gain you never made.
-
Your entire financial history sits on someone else's server.
Your addresses, xpubs, and every transaction live on someone else's server. All it takes is one data breach.
-
Your books don't balance. You can't prove they do.
A matching wallet total is not a ledger. Without double-entry, there is nothing to audit.
Clams was built for exactly this.
- Data stays on your machine by default.
- Recognizes transfers from real sales.
- Balances derived from real double-entry accounting.

- Role-based access with Google, Apple, or email magic-link sign-in
Specialization
Bitcoin-native
Built for multisig and the complex transactions legacy tools choke on.
- Reconcile multisig wallets automatically. No manual matching.
- Account for channel opens, closes, and force-closes, not just payments.

- Account for L-BTC and Liquid assets like USDt alongside your BTC
