Onsei Wallet is an open-source, non-custodial wallet built for the Sei Network. This repository serves as a minimal reference implementation that can be used as a starting point for developers building their own wallet solutions or integrating Sei-related functionality into other applications.
- Sending and receiving SEI tokens
- Viewing transaction history
- Managing address book entries
- Creating new wallets using mnemonic phrases
- Importing existing wallets
- Setting custom network fee parameters
- Enabling biometric and PIN-based security
- Configuring in-app notifications
This project is intended as an open-source example that can be adapted and extended to meet different needs across the Sei ecosystem.

The Onsei Wallet (testnet version) is available on the App Store and Google Play. It can be downloaded for testing and exploration purposes.
Note: Make sure you have completed the React Native - Environment Setup instructions till "Start your Application" step, before proceeding.
There are two ways to run your project:
Install Expo Go application on your phone.
npm start
Scan the QR code generated in the terminal with Expo Go.
Make sure to have any simulator installed on your device.
npm run android
OR
npm run ios
Make sure to have the newest android build:
npx expo run:android
Add a detox (e2e testing library) configuration to it
npm run e2e-configure
Now the tests are ready to go. Open two terminals. In one of them run:
npm start
And in the second:
npm run e2e-test
If you're encountering any errors while running tests, make sure that your Java version is set to 17.0.11. If your version doesn't match, the easiest way to change it is to install -> https://sdkman.io/install and then run
sdk install java 17.0.11-zulu
If you're getting $ANDROID_SDK_ROOT is not defined error, run
export ANDROID_SDK_ROOT=/Users/${USER}/Library/Android/sdk
Before proceeding, make sure to have eas installed and logged in
npm install -g eas-cli
eas login
Run those commands:
eas build --platform ios
eas submit
In the menu that appears choose the latest build and confirm. This process takes a few minutes.
For Android, you'll need to get the upload key. Ask someone from your team for a my-upload-key.keystore file and the password. Save those in a safe place.
Then run
eas credentials
In the menu pick "Android", then "production" and "Keystore".
From this menu, select "Set up a new keystore", and when asked to "Generate a new Android Keystore?", answer "No". You will then be asked for the path to the Keystore file. Provide the path to my-upload-key.keystore.
When asked for an alias, type "my-key-alias", and when asked for a password, enter the one provided by your team.
You can now run
eas build --platform android
The newly generated build can be downloaded from expo.dev panel. It can be uploaded into the Google Play Store.
