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

Chrome Extension Store

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.

1.3.0 Update

The latest release brings:

• Support for dApps to submit multisig transactions and retrieve the single associated address signature.

Roadmap

The next feature release will be a feature release permitting the addition and configuration of networks, planned for early 2021.

Multisig Transactions

• Multisig transactions can be signed individually through AlgoSigner.
  • Using the associated msig for the transaction an available matching unsigned address will be selected if possible to sign the txn component.
  • The resulting sign will return the a msig with only this signature in the blob and will need to be merged with other signatures before sending to the network.
• An example of this can be seen in the existing sample dApp multisig test.

Atomic Transactions

• Grouped transactions intended for atomic transaction functionality need to be grouped outside of AlgoSigner, but can be signed individually.
• The grouped transactions need to have their binary components concatenated to be accepted in the AlgoSigner send method.
• An example of this can be seen in the existing sample dApp group test.

Decentralized Applications

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

Developing a dApp

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

Project Structure

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

Build and Install

The ./dist/ folder is the only required folder to install the extension yourself from code and must be built.

• Clone the repository locally
• Run npm install in the root folder
• Run npm run build in the root folder — this creates the dist folder
• Open Chrome browser — go to chrome://extensions/
• Enable developer mode
• Select Load Unpacked and choose the just created dist folder
• AlgoSigner is now installed and available

Install from zip

The latest built zip is available for download on the releases page —

NoteL this is not recommended for non-developers and should never be used for production purposes. Extreme caution should be taken when installing any wallet.

Prerequisites

• Installation of the Chrome browser
• File unzip program
• Local file system write permissions
• Access to set developer mode in Chrome and install unpacked extensions

Process

• Unzip AlgoSigner.zip file to local file system
• Open Chrome browser and go to chrome://extensions/
• Enable developer mode
