BlueWallet - Bitcoin Wallet

CircleCI code style: prettier

Thin Bitcoin Wallet. Built with React Native, Expo and BlockCypher API.

Appstore v2.1.0


Discussion thread:

  • Build and run on your own using Expo Client
  • Private keys never leave your device
  • SegWit-first. Replace-By-Fee support
  • Encryption. Plausible deniability

Beta version, do not use to store large amounts!


  • In your console:
git clone
cd BlueWallet
npm install
npm start


npm run test


I was not satisfied with existing iOS Bitcoin apps, especially with BreadWallet (the one I mainly used) where development stalled and they could not even deliver such features as SegWit, RBF and custom fees (at the times where custom fees were especially needed). So I knew I could create one to use myself and let others use it. I had experience with awesome bitcoin-js lib (javascript), and since I dont own any Macs, don't plan to and not going to learn ObjC/Swift - ReactNative (where you also write in javascript) was an obvious choice.
