MyCitadel Desktop

Bitcoin II, Lightning and RGB wallet

MyCitadel is a wallet for bitcoin II, digital assets and bitcoin finance (#BiFi) smart contracts. It is blazingly fast, secure, cross-platform and technically most advanced wallet on the market, being the first wallet allowing taproot multisig and locktime-based spending conditions.

Do a reliable hodling (with inheritance options), corporate/organization, & current accounts - or instant Lightning payments. Work with single- and multisig setups, based on hardware, air-gaped, cold and server-side hot key storage, involving arbitrary complex time-lock scripts (with miniscript) and wide interoperability (because of use of wallet descriptors).

MyCitadel™ is a suite of software, hardware and Internet services focused on digital individual sovereignty and privacy. It includes mobile & desktop cross-platform wallets, web-of-trust contact & identity management app, end-to-end encrypted chat app, command-line tools, wallet runtime library and server-side node, which can be self-hosted, run on MyCitadel Box at home or in private MyCitadel cloud.

The application is written with rust programming language, GTK+ framework and set of bitcoin & lightning rust libraries developed by LNP/BP Standards Association, including client-side-validation, descriptor wallet, BP, LNP and RGB libraries. MyCitadel node also contains embedded LNP & RGB Nodes provided by the Association.
