This framework is pure Swift 5 and is available via Swift Package Manager. It contains several major components:
URDecoder, A codec for URs that supports single-part and multi-part transmission using fountain codes.
FountainDecoder: A general codec for binary strings based on Luby Transform code.
Bytewords: A codec for Bytewords.
If you are using this framework at it's highest level, the main types of interest will be
The CBOR codec is provided because the message of a compliant UR must be encoded in CBOR, and multi-part URs embed fragment data in a CBOR structure containing metadata needed by the decoder. For your own UR structures, you can use a different CBOR codec as long as the message encoded is well-formed CBOR.
The other layers may be used independently if desired.
There is also an iOS app, URDemo, that demonstrates URKit by sending and receiving long binary messages via animated QR codes containing multi-part URs.
URKit is currently under active development and in the late alpha testing phase. It should not be used for production tasks until it has had further testing and auditing.

URKit is a project of Blockchain Commons. We are proudly a "not-for-profit" social benefit corporation committed to open source & open development. Our work is funded entirely by donations and collaborative partnerships with people like you. Every contribution will be spent on building open tools, technologies, and techniques that sustain and advance blockchain and internet security infrastructure and promote an open web.
To financially support further development of URKit and other projects, please consider becoming a Patron of Blockchain Commons through ongoing monthly patronage as a GitHub Sponsor. You can also support Blockchain Commons with bitcoins at our BTCPay Server.
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.
