HODL Wallet

HODL Wallet is a free, open-source and decentralized Bitcoin wallet that’s available for both iOS and Android. I have been involved with the project from initial idea through launch and beyond. The iOS marketplace lacked a Bitcoin focused decentralized wallet and we knew we could fill this gap with HODL. I was the lead developer of the prototype, a bitcoin-only fork of the original BRD wallet, helped transition the development to an in-house team and develop landing pages.
