A CLI tool for signing and verifying messages with ECDSA and Schnorr using libsecp256k1.
musign-cli is currently under active development but is only in the research phase. It should not be used for production work — it can and WILL change. See Release Path.
- single signatures schnorr
- single signatures ecdsa
- legacy Bitcoin signing
- traditional multisignatures
- json-ld signing
- musig2 (see Replace MuSig(1) module with MuSig2 #131
- BIP322 support
- UR support (needs CBOR spec first)

We encourage public contributions through issues and pull requests! Please review CONTRIBUTING.md for details on our development process. All contributions to this repository require a GPG signed Contributor License Agreement.
The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.
Gordian System Discussions. For users and developers of the Gordian system, including the Gordian Server, Bitcoin Standup technology, QuickConnect, and the Gordian Wallet. If you want to talk about our linked full-node and wallet technology, suggest new additions to our Bitcoin Standup standards, or discuss the implementation our standalone wallet, the Discussions area of the main Gordian repo is the place.
Wallet Standard Discussions. For standards and open-source developers who want to talk about wallet standards, please use the Discussions area of the Airgapped Signing repo. This is where you can talk about projects like our LetheKit and command line tools such as seedtool, both of which are intended to testbed wallet technologies, plus the libraries that we've built to support your own deployment of wallet technology such as bc-bip39, bc-slip39, bc-shamir, Sharded Secret Key Reconstruction, bc-ur, and the bc-crypto-base. If it's a wallet-focused technology or a more general discussion of wallet standards,discuss it here.
Blockchain Commons Discussions. For developers, interns, and patrons of Blockchain Commons, please use the discussions area of the Community repo to talk about general Blockchain Commons issues, the intern program, or topics other than the Gordian System or the wallet standards, each of which have their own discussion areas.
As an open-source, open-development community, Blockchain Commons does not have the resources to provide direct support of our projects. Please consider the discussions area as a locale where you might get answers to questions. Alternatively, please use this repository's issues feature. Unfortunately, we can not make any promises on response time.
If your company requires support to use our projects, please feel free to contact us directly about options. We may be able to offer you a contract for support from one of our contributors, or we might be able to point you to another entity who can offer the contractual support that you need.
