Ironbelly is a mobile wallet for Grin/Mimblewimble blockchain. It's first of a kind. The goal is to provide an easy and simple way to hold and transfer Grins between people. It is open-source and free to use. Ironbelly is currently in beta testing for iOS. At the moment, the only testnet is enabled, but I plan to enable mainnet soon. On the roadmap for upcoming months is adding password protection, multi-account, transaction building over HTTPS and launch of the Android version. This fund would allow me to dedicate significantly more time on it, so I can fix bugs and deliver features faster, also cover the cost of establishing a legal entity (AppStore requirement for cryptocurrency wallets).
