mSIGNA is a cross‑platform desktop Bitcoin wallet focused on security‑first custody. It centers on multisignature “vaults,” letting you define m‑of‑n spending policies and coordinate approvals across multiple devices or participants. The wallet cleanly separates watching from signing, so you can keep keys offline, prepare transactions online, and authorize them on an air‑gapped machine. It also employs deterministic key management to simplify backups and recovery. mSIGNA is well‑suited to teams and advanced users who need rigorous control over funds and cold‑storage workflows.
mSIGNA is developed by Ciphrex Corporation and is used by 4 users of Software Informer. The most popular versions of this product among our users are: 0.9 beta and 0.9. The name of the program executable file is msigna.exe.
