Polkagate Snap: Polkadot with Metamask

PolkaGate Snap

A MetaMask snap for seamless interaction with the Polkadot ecosystem, a prominent platform for cross-chain communication and scalability. Now you can use your MetaMask wallet to access Polkadot dApps and tokens effortlessly.

To integrate this snap into your dApp, you can easily upgrade your existing @polkadot/extension-dapp by replacing it with @polkagate/extension-dapp. It's important to note that once our changes are merged into the official extension-dapp, this manual update will no longer be necessary.

⏬ Polkagate snap is now available on MetaMask Snap Directory for download: https://snaps.metamask.io/snap/npm/polkagate/snap/

Running the Repository

The repository contains a dApp located in the ./packages/dapp directory and the snap code, which can be found in ./packages/snap. To try out the snap, follow these steps in your terminal:

git clone https://github.com/PolkaGate/snap.git
cd snap
yarn install
yarn run start

After executing these commands, you can access a basic decentralized application (dApp) page for testing the snap at http://localhost:8000/. For more advanced dApp visit apps.polkagate.xyz. Note, MetaMask Flask (MetaMask) needs to be installed to interact with the snap and dApp.

Test

To execute the unit tests for the snap, use the following command(s):

yarn install
yarn build
yarn test

Docker

To build and run docker container(s) run:

yarn install
yarn compose

Afterward, you can access user interfaces as follows:

• http://localhost:8000: This displays a dapp designed for testing the snap.

• http://localhost:80: This presents a modified version of the Polkadot Cloud in the staking dashboard.

Note: This MetaMask snap operates autonomously and does not rely on other extensions within the Polkadot ecosystem for its functionality.

support for showing native and inApp notifications

snap_notify can be utilized to show native and inApp notifications if needed

not support for substrate chain

During usage, we have found that the current Snap does not support substrate chains other than parachains. Are there considerations to provide support for more chains in the future? Given the increasing popularity of Coretime, a greater number of chains will be joining the ecosystem. Currently, the process of obtaining the WS_URL through { selectableNetworks } from '@polkadot/apps-config'; is hindering the adoption and use of a large number of substrate chains.
