About Keylay

Keylay is a free and open-source tool for coordinating multisig Bitcoin wallets with remote participants — securely, privately, and without a central server.

Designed to support air-gapped signing and communication over encrypted relays, Keylay helps you:

• Share wallet descriptors and partially signed Bitcoin transactions (PSBTs)
• Coordinate across locations and devices
• Preserve privacy and reduce metadata
• Operate in high-risk or repressive environments

Whether you're a human rights activist, journalist, NGO treasurer, or cautious Bitcoiner, Keylay offers a powerful way to coordinate multisig custody with minimal infrastructure — directly from your browser.
