Development

Prerequisites

MetaMask Flask
- ⚠️ You cannot have other versions of MetaMask installed
Nodejs 16. We strongly recommend you install via NVM to avoid incompatibility issues between different node projects.
- Once installed, you should also install Yarn with npm i -g yarn to make working with this repository easiest.

Installing

nvm use
yarn setup

Running

Snap

⚠️ When snap updates you will need to still reconnect from the dapp to see changes

# Running Snap via watch mode
yarn workspace @consensys/starknet-snap watch

Alternatively you can build and serve the snap manually. This can sometimes be more stable than watch mode but requires a manual rebuild and serve anytime there is a change on the snap.

# Building and serving snap manually
yarn workspace @consensys/starknet-snap build
yarn workspace @consensys/starknet-snap serve

UI

# Running Wallet UI
yarn workspace wallet-ui start

# Running Storybook
yarn workspace wallet-ui storybook

Snap server and debug page: http://localhost:8081/
