React Native Web3 Wallet

Web3 Wallet in React Native (use bitcoinjs-lib)

Welcome

This is a safe web3 wallet tools, to help with develop wallet applications quickly.

main branch support ethers5.x
ether6.x branch support ethers6.x
bitcoin branch support bitcoinjs

Installation

npm install "github:heroims/react-native-web3-wallet#bitcoin" --save
npm install rn-nodeify  --save

npm install(at this point the postinstall does rn-nodeify --install buffer,stream,assert,events,crypto,vm,process --hack) npx pod-install
