Semaphore Boilerplate

The repository is divided into two components: web app and contracts. The app allows users to create their own Semaphore identity, join a group and then send their feedback anonymously (currently on Sepolia).

Deploy the contract

1. Go to the apps/contracts directory and deploy your contract:
