ZK Keeper

CryptKeeper Browser Extension

CryptKeeper is a browser extension which enables Zero knowledge identity management and proof generation. Currently it supports operations for Semaphore and RLN gadgets.

This plugin is still in development phase.

The following features are supported currently:

• Identity secret and Identity commitment generation
• Semaphore ZK-Proof generation
• RLN ZK-Proof generation

The plugin uses the zk-kit library.

Proof generation is enabled in two ways:

• by providing merkle witness directly
• by providing a secure service address from which the merkle witness should be obtained

Development

1. npm install
2. npm run dev
3. Load the dist directory as an unpacked extension from your browser.

Demo

1. npm run dev or npm run build
2. npm run merkle
3. cd demo && npm install && npm run start

E2E

1. Run npx playwright install --with-deps chromium to install playwright dependencies
2. Run npm install for extension and for demo
3. Make sure you have .env.test file with METAMASK_EXTENSION_ID.
4. METAMASK_EXTENSION_ID can be found in log output for npm run e2e. For different environments METAMASK_EXTENSION_ID is also different so we need to specify it explicitly.
5. Run npm run build:e2e to build the extension
6. Run npm run e2e to run playwright e2e tests
