Using Snaps to add a non-EVM chain to MetaMask

MetaMask is a popular cryptocurrency wallet and browser extension that allows users to interact with decentralized applications (dApps) built on the Ethereum network. However, MetaMask currently only supports chains that are compatible with the Ethereum Virtual Machine (EVM).

For users who want to interact with non-EVM chains, adding custom networks to MetaMask has traditionally been a complex and manual process. However, the introduction of Snaps has made it easier for developers to add support for non-EVM chains to MetaMask.

What are Snaps?

Snaps are a new feature introduced in MetaMask that allows developers to create and distribute custom plugins that add functionality to the MetaMask wallet. Snaps can be used to add support for non-EVM chains, custom transaction types, and other features that are not natively supported by MetaMask.

Adding a non-EVM chain with Snaps

To add a non-EVM chain to MetaMask using Snaps, users can simply install the Snap for the desired chain from the MetaMask extension. Once installed, the Snap will add support for the non-EVM chain to the user’s MetaMask wallet, allowing them to interact with dApps and perform transactions on the non-EVM chain.

Developers can create and distribute Snaps for non-EVM chains by leveraging the MetaMask snap plugin API. This API provides a set of tools and resources that allow developers to build and distribute custom Snaps that add support for non-EVM chains and other custom features to MetaMask.

Conclusion

Snaps have made it easier for developers to add support for non-EVM chains to MetaMask, providing users with more options for interacting with different blockchain networks. By leveraging the MetaMask snap plugin API, developers can create and distribute custom Snaps that add support for non-EVM chains, custom transaction types, and other features to MetaMask, expanding the capabilities of the popular cryptocurrency wallet and browser extension.
