Clams

Clams is a Bitcoin-native accounting infrastructure built specifically for Bitcoin and Lightning, rather than retrofitted from fiat accounting tools. It provides precise, audit-ready double-entry accounting with automated reconciliation, capital gains calculations, and detailed reporting. The desktop app processes everything locally for maximum privacy, while upcoming REST API and hosted deployments will enable Bitcoin companies, node operators, and accounting firms to integrate Clams at scale. Built on a Rust-powered core, Clams delivers high performance, full privacy, and the only comprehensive solution for Lightning Network accounting available today.
