Nomo App Developer Docs

In the beginning, the Nomo App was only a crypto wallet, but now the Nomo App offers a huge range of web3-features. To enable those web3-features, the Nomo App uses the following open-source packages:

• WebOns: Decentralized Apps (“dApps”) are running within the Nomo-WebView.
• WalletKit-Dart: A library for interacting with multiple chains.
• Nomo-UI-Kit: A collection of Flutter-widgets with Nomo design.
• Nomo-ID: A protocol for authenticating via the Nomo App.

WebOns

See on GitHub: https://github.com/nomo-app/nomo-webon-kit

A WebOn is a web application that works within the Nomo App. WebOns are a powerful capability of the Nomo App that unlock the following features in an easy-to-use way:

• Excellent user experience for web3: No more “Connect wallet” buttons; no more middlemans between web application and wallet.
• Decentralized messaging.
• Optional: Verification that users are real via a KYC mechanism.
• Authentication with Nomo-ID or Nomo-Auth.
• And much more to come…

The Nomo-WebOn-Kit provides a Demo-WebOn to showcase functionality. Moreover, Nomo provides the following npm packages for WebOn developers:

• https://www.npmjs.com/package/nomo-webon-kit
• https://www.npmjs.com/package/ethersjs-nomo-webons
• https://www.npmjs.com/package/nomo-webon-cli
• https://www.npmjs.com/package/nomo-messenger-kit
• https://www.npmjs.com/package/nomo-auth

WalletKit-Dart

See on GitHub: https://github.com/nomo-app/walletkit-dart

The WalletKit-Dart is an advanced library that provides wallet functionality for multiple chains. The WalletKit-Dart supports both UTXO-chains and EVM-chains, including features like xPub/zPub/P2SH/SegWit.

Nomo BIP39

See on GitHub: https://github.com/nomo-app/bip39

To protect Nomo users, the Nomo team maintains its own fork of BIP39 with additional security hardenings. The WalletKit-Dart depends on Nomo BIP39.

Nomo-UI-Kit

See on GitHub: https://github.com/nomo-app/nomo-ui-kit

Nomo-UI-Kit offers a collection of reusable widgets, such as buttons and cards. Nomo-UI-Kit is designed for both the Nomo App itself as well as WebOns that are built with Flutter-Web.

Nomo-WebView

See on GitHub: https://github.com/nomo-app/nomo-webview

Nomo-WebView allows to convert between JavaScript-Promises and Dart-Futures, such that async/await works seamless across language boundaries.

Nomo-ID

See on GitHub: https://github.com/nomo-app/nomo-id

Nomo-ID is a flexible protocol for web3-based authentication, without any passwords. There exist multiple websites that allow login via Nomo-ID, but Nomo-ID can do much more than logins. The Nomo-ID repo contains a specification of the protocol as well as a sample application.
