This repo contains the Connect by Drift Snap for MetaMask that allows MetaMask to function as a Solana wallet, and a wallet adapter that extends the Solana wallet standard to connect to this snap.
Prerequisites: Have bun installed
Steps: 1. Run build_snap.sh from the main folder of the repo: ``` ./build_snap.sh ``` ---
Connect by Drift Snap:
Run yarn dev from the snap folder.
Snaps are served from a url which must either be localhost or npm.
Running yarn dev in the snap folder will start webpack in watch mode, and start an express server to serve the snap bundle.
Some caveats:
- We are currently not using the snaps cli (
@metamask/snaps-cli) because it was throwing errors trying to compile@solana/web3.js. It's optional anyway but something to be aware of. - Using webpack with a plugin for snaps instead.
- The
snaps-webpack-pluginfolder is a COPY of the official snaps webpack plugin, because the official one threw the errorundefined is not a constructorwhen trying to import and use in the webpack config. Possibly fixable by adjusting the project setup (using esm or ts for the webpack config?), we should revisit this later. For now the source code has been copied and changed to a named export which works. To rebuild the webpack plugin, runyarn build-webpack-plugin
Wallet Adapter:
Just run yarn build && yarn link, then run yarn link @drift-labs/snap-wallet-adapter from the Drift UI. It doesn't have a watch feature so you need to run this each time you make a change but it's pretty fast.
To use the wallet adapter in the UI with the Snap being served locally, set the snapId param of the constructor to: local:http://localhost:8080
In the Drift UI, you should set these environment variables for local development:
NEXT_PUBLIC_MM_SNAP_ENABLED=true
NEXT_PUBLIC_MM_SNAP_ID=local:http://localhost:8080
NEXT_PUBLIC_MM_SNAP_VERSON=<current version>
New releases should update the npm package version of the wallet adapter and snap, add a git tag with the matching verison, and publish to npm.
Release automation coming soon.
