Project Overview 📄

Polkagate is a dedicated team of Polkadot enthusiasts, actively involved in various aspects of community development. Our multifaceted contributions encompass the development of the Polkagate extension, as well as the efficient management of Polkagate's Polkadot and Kusama pools. Today, we are excited to present our latest initiative aimed at further enriching the Polkadot ecosystem.

Introducing a revolutionary project with the vision of bridging the gap between the Polkadot ecosystem and the vast user base of Metamask, which boasts over 30 million users. We are committed to creating a seamless connection between these two vibrant communities, opening up new possibilities and opportunities for all involved.


This project includes a signer Snap for the Polkadot ecosystem on MetaMask. It seamlessly integrates with all existing dApps without requiring any code modifications. The Signer is capable of signing not only Polkadot and Kusama extrinsics but also extrinsics from all other Substrate-based chains that align with Polkadot.js APIs.


Project Details

We've prepared two demo videos 1 and 2, showcasing how Polkadot.js Apps an Staking dashboard are seamlessly connected with MetaMask using the Polkagate Signer Snap. This Snap flawlessly signs transactions, enhancing the user experience.

Our project primarily utilizes JavaScript and TypeScript for development, ensuring accessibility and extendability for developers interested in contributing fresh ideas.

While not a full-fledged extension like existing Polkadot ecosystem extensions such as Polkagate, Subwallet, or Talisman, our project has the potential to evolve into a comprehensive extension. This transformation is contingent on MetaMask expanding the capabilities of its Snaps, which some of them are currently accessible only to developers using MetaMask Flask.

To uphold Snap security, MetaMask requires audits from selected teams. We are in the process of arranging these audits to ensure a high level of security. Additionally, we have plans to further enhance the extension's capabilities as soon as MetaMask provides Snaps with more functionalities.

Ecosystem Fit

Where and how does your project fit into the ecosystem?

Polkamask is designed to seamlessly integrate into the Polkadot and Kusama ecosystems by enhancing the interaction between MetaMask and Substrate-based chains. It introduces the Polkagate Signer Snap, allowing users to access and utilize the Polkadot and Kusama networks without any code modifications. It aims to bridge the gap between MetaMask and the Polkadot ecosystem, making it more accessible and user-friendly.

Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

Our primary target audience includes dApp developers and users who engage with the Polkadot and Kusama ecosystems through MetaMask. We aim to provide a solution that benefits developers by simplifying the integration process and offers users a smooth experience when interacting with Polkadot and Kusama dApps through MetaMask.

What need(s) does your project meet?

Polkamask addresses the need for seamless integration between MetaMask and Substrate-based chains like Polkadot and Kusama. It removes barriers and complexities in the user experience, allowing MetaMask users to access these ecosystems without having to modify existing dApps. This simplification and user-friendliness are essential for the broader adoption of Web3 technologies.

Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

There are existing projects in the Polkadot ecosystem that aim to enhance the user experience and accessibility. One example is the Polkadot wallet Snap developed by ChainSafe. However, it primarily supports Polkadot, Kusama, and Westend based on their codebase on GitHub. An important distinction is that integrating with this wallet Snap often requires dApps to undergo modifications to utilize the Snap, which can be a significant barrier to integration.

In contrast, Polkamask differentiates itself by introducing the Polkagate Signer Snap. This Snap offers seamless integration with MetaMask, providing a user-friendly experience and eliminating the need for dApps to make code modifications. This ease of use and the ability to connect to Substrate-based chains without requiring code changes make Polkamask a unique and valuable addition to the ecosystem.

Development Status 📖

While our project code is currently housed in a private repository due to its work-in-progress (WIP) nature, we have made two essential packages available for the community:

These packages serve as initial contributions to our project and provide a foundation for what's to come. We look forward to further developing and sharing our work as it matures.
