This application provides an interface for managing keystores for Waku's rate-limiting nullifier (RLN) functionality. It integrates with MetaMask for wallet connectivity.

Features

Connect to MetaMask wallet
View wallet information including address, network, and balance
Support for Linea Sepolia testnet only
Keystore management functionality
Token approval for RLN membership registration

Getting Started

First, install the dependencies:

npm install

Run the development server:

npm run dev

Open http://localhost:3000 with your browser.
Connect your MetaMask wallet (Linea Sepolia testnet is required).

Linea Sepolia Network

This application is configured to use ONLY the Linea Sepolia testnet. If you don't have Linea Sepolia configured in your MetaMask, the application will help you add it with the following details:

Network Name: Linea Sepolia Testnet
RPC URL: https://rpc.sepolia.linea.build
Chain ID: 59141
Currency Symbol: ETH
Block Explorer URL: https://sepolia.lineascan.build

You can get Linea Sepolia testnet ETH from the Linea Faucet.

RLN Membership Registration

When registering for RLN membership, you'll need to complete two transactions:

Token Approval: First, you'll need to approve the RLN contract to spend tokens on your behalf. This is a one-time approval.
Membership Registration: After approval, the actual membership registration transaction will be submitted.

If you encounter an "ERC20: insufficient allowance" error, it means the token approval transaction was not completed successfully. Please try again and make sure to approve the token spending in your wallet.
