The @portal-hq/mobile-key-values package contains a storage adapter intended for use with the @portal-hq/core package. This storage adapter allows end users to save MPC shares to their local device keychain using react-native-mmkv. Note: This storage provider is only supported on iOS devices, so should not be used as your sole backup storage adapter unless you are explicitly releasing an iOS-only app.

​
Basic usage

​
Install the package in your React Native project.

  • yarn
  • npm
yarn add @portal-hq/mobile-key-values

​
Import the package into the component where you initialize the Portal class

import Portal from '@portal-hq/core'
import Keychain from '@portal-hq/mobile-key-values'

​
Register your storage adapter and initialize the Portal class

const keychain = new Keychain() // Optionally accepts an MMKV configuration object
const portal = new Portal({
  // ...your other config options
  keychain,
})

​
Dependency linking

Because this package uses the react-native-mmkv package (which contains native modules) there is some additional linking required to make it work with your React Native project. Explicitly install the react-native-mmkv package in your project.
  • yarn
  • npm
yarn add react-native-mmkv
