Clams v1: Local-First Accounting for Bitcoin, Lightning, and Liquid

Clams started as a free desktop app, and over 3,000 individuals and businesses downloaded it. Everything we learned from them about Bitcoin accounting went into our updated vision for Clams, and in February we shipped it as a public beta: the same engine, rebuilt in Rust, one binary, two interfaces.

Since then, the feedback hasn't stopped. Requests hit our inbox via the CLI or an agent: new features, bug fixes, and better support for weird edge cases. We've also been working closely with design partners, who shared their accounting headaches so we could solve them together. That's how we learned where the real pain is for businesses bringing Bitcoin into their day-to-day operations, and it's what gives us the confidence for what comes next.

Today we're announcing that Clams is out of beta. v1 is here. We couldn't have done this without the founders and businesses who put their faith in us early and told us what they needed.

Three problems we hear again and again

Over two years of building, here's what we learned matters most:

Transfers get mistaken for sales. When a tool counts a wallet-to-wallet transfer as a disposal, it invents a gain that never happened, distorts your cost basis, and you overpay.

Your data leaves your machine. On hosted platforms, your full transaction history sits on someone else's server, governed by their security practices and their policies.

Your books never actually close. The wallet balance matches, but the books don't. Other tools give you a number, not the double-entry bookkeeping a real business needs.

Clams solves all three. It matches high-confidence transfers automatically, including between on-chain and Lightning, and flags anything ambiguous for your review, so a move between your own wallets doesn't get booked as a disposal. Your accounting backend, ledger, and reports live on infrastructure you control, local or self-hosted; Clams uses hosted services only for identity and exchange rates. And it gives you real double-entry books, with a full audit trail behind every entry.

The result is Bitcoin accounting you can stand behind. Hook up your Lightning nodes and on-chain wallets, import CSV exports from your exchanges, and you'll get journals, balances, portfolio history, and capital gains from a deterministic engine, with the working behind every number.

Two ways to use Clams

You can run the software yourself, or bring in the team behind it.

Running it yourself means downloading Clams and signing in with your email. An individual running a small business, a four-person accounting firm, and a startup where the CFO and founder both need access all run the same software. Add as many people and sets of books (profiles) as you need, and we never limit wallets, transactions, or reports. For the vibecoders out there, you can pair your AI agents with our skills and start building your own internal dashboards with the REST API.

Enterprise: hire the team behind Clams

And for teams who want more than the software, we're rolling out an enterprise offering: we embed with you to give you the business intelligence you've been missing. It can start with us helping you deploy Clams and connect your wallets, and it scales all the way up from there.

That means custom dashboards. Cron jobs that send reports to you, your accountant, your investors, on the first of the month, the quarter, whatever cadence you need. And it means building out a company brain that hooks into Slack, your email, your internal tools. Ask questions of your books, in plain language. Clams becomes the base layer you can trust: the deterministic engine computes every value from your reviewed books, and the agent orchestrates but never invents a number.

The payoff is real: when you trust your numbers, you make sharper decisions, move faster than your competition, and give your business a far better shot at succeeding.

To our v1 beta testers

Thank you for helping us get here.

What's next

We're excited for this next chapter. We have a lot in the works, including some partnerships we'll be announcing very soon.

So download Clams today. Every month you wait is another month of history to reconstruct later. Start now, and when January comes your 2026 capital gains report is a review, not a reconstruction.
