Bitcoin Multisig Wallet

Open-source multi-key self-custody — no single point of failure. Passphrase + hardware key (e.g. YubiKey) + optional third key. Built for true cold storage you control.

From the @block_unlocked1 feed — why multi-key beats a single hardware wallet.

m-of-n keys e.g. 2-of-3: lose one key, funds stay safe. Steal one key, still not enough to spend.

Open source No closed microcontroller firmware as the only gate. Code you can audit and host yourself.

Hardware + software Combine passphrase, YubiKey / similar, and a third factor — raise the attack bar massively.

Multisig concept visual 2 — Hardware issues are a pattern — open Multisig is the answer

Multisig post visual — Would you switch if it was simple enough?

Status: Placeholder on the main site so the product is visible early. The wallet itself is not live yet — no keys, no funds, no downloads here. Not investment advice; self-custody always carries operational risk.
