npm install text-encoding buffer   #for gun/sea deps
npm install github:bmatusiak/gun-rebuild github:bmatusiak/gun-rebuild-sea github:amark/gun   #for gun/sea
npm install react-native-webview react-native-webview-crypto expo-crypto  #for crypto
npm install @react-native-async-storage/async-storage   #for gun storage

step3: loading gun (App.js)
