Bitcoin already has undeniable product–market fit as savings technology. At Hoseki, we believe that when you choose to save in self-custody—without relying on counterparties—you should also be able to use those savings as wealth. That’s why we built Hoseki Prove.

Today, we’re opening a private beta for Prove—the fastest way to generate real-time, financial-style statements for your self-custodial Bitcoin. Prove turns private ownership into a usable financial asset, without moving a single sat and without compromising your keys.

Prove makes statements simple and familiar. It takes your self-custody and presents it as a clear, bank-style statement — showing balances and transaction flow in the same format institutions already understand. You stay in control at every step: choose which wallets to include, see exactly what’s shared and with whom, and revoke access anytime. No XPUBs or addresses are ever shared without your explicit approval.

Security and privacy are built in with strong encryption and secure authentication. Balances and transactions sync automatically so statements are always current. Your keys, your coins—Prove never requires transfers or custodial hand-offs.

How it works:

1. Connect your wallet and select accounts
2. Prove control over the private key
3. Download your statement—ready whenever you need it

We’re inviting our waitlist first, but anyone can join by reaching out to support@hoseki.app. We welcome feedback—let us know your thoughts and experiences.
