An open-source Algorand wallet browser extension that permits dApp communication for signing Algorand transactions - available for Chrome initially.

The extension is available on the Chrome Extension Store

This is the preferred solution for end-users, updates will be automatically installed after review by the extension store

Developers working with dApps may also install directly from the release package, or by downloading the project and building it.

As a browser extension, AlgoSigner opens the door for developers to build DeFi applications on Algorand by providing a secure way to add transaction capabilities. This enables developers to initiate transactions and accept ALGOs seamlessly, without jeopardizing the security of their users’ secrets.

For end users, AlgoSigner also makes it easy to use Algorand-based applications on the web. Simply create or import your Algorand account, visit a compatible dApp, and approve or deny transactions — all from within your browser.

DApp users can trust AlgoSigner to:

• Securely store and encrypt account secrets
• Authorize transactions without giving dApps direct access to their keys
• Sign and approve transactions when using dApps

• Read dApp Integration Guide
• Read Sample dApp project
• Try Interactive dApp

There are multiple packages in the project that combine to build the overall extension. Each component package is designed so that it's functionality doesn't require the rebuild of other packages and will be combined to build the deployable extension.
