About SigningRoom.io

The Problem: Coordinating a Bitcoin multisig transaction is notoriously clunky. Teams usually find themselves emailing PSBT files back and forth, pasting hex data into Telegram, or losing track of who has signed what. It’s a slow, manual process that introduces unnecessary friction into high-security workflows.

The Solution: SigningRoom.io is a "virtual war room" for your multisig transactions. It provides a real-time, collaborative environment where teams can coordinate signatures instantly.

How it Works:

Create a Room: Generate a secure, temporary space with a single click.

Invite Co-signers: Share the end-to-end encrypted link with your partners.

Sign & Merge: Upload your PSBTs, see real-time updates as others sign, and download the finalized transaction once complete.

Architected for Privacy:

Zero Database: We don't store your data. Rooms exist only in memory via Cloudflare Durable Objects and vanish when the session ends.

No Accounts: No email, no passwords, no KYC. Start signing in seconds.

True E2EE: Encryption keys are stored in the URL fragment. Because the fragment is never sent to our servers, the host is mathematically incapable of seeing your transaction data.

Stateless Coordination: Designed for teams who prioritize data sovereignty without the headache of manual file management.

Streamline your Bitcoin operations without compromising on the "Don't Trust, Verify" ethos.
