Brewit Contracts

A collection of smart contracts for the Brewit platform, including badge management, smart sessions, and WebAuthn validation.

Overview

This repository contains several key components:

1. Badges System

   • ERC1155-based soulbound badges
   • Signature-based minting
   • Flexible token rendering
   • Role-based access control

2. Smart Sessions

   • ERC-7579 compatible smart account sessions
   • Granular control over session keys
   • Support for various policy types
   • Integration with external policy contracts

3. WebAuthn Validators

   • WebAuthn2/FIDO2 authentication
   • ECDSA P256 optimization
   • FreshCryptoLib integration

Project Structure

Development

Prerequisites

• Foundry
• Node.js
• SageMath (for WebAuthn validators)

Setup

1. Clone the repository:

git clone <repository-url>
cd brewit-contracts

2. Install dependencies:

forge install

3. Create a .env file with your configuration:

PRIVATE_KEY=your_private_key
API_KEY_ALCHEMY=your_alchemy_key
ETHERSCAN_API_KEY=your_etherscan_key
# Add other API keys as needed

Testing

Run tests for all components:

forge test

Run tests for specific components:

# Badges
cd badges && forge test

# Smart Sessions
cd smartsessions && forge test

# WebAuthn Validators
cd validators/webauthn && forge test

Deployment

Deploy to a network:

forge script script/Deploy.s.sol --rpc-url <RPC_URL> --broadcast

Components

Badges

The badge system implements ERC1155 tokens with soulbound functionality:

• Non-transferable tokens
• Signature-based minting
• Customizable token rendering
• Role-based access control

Smart Sessions

Smart session management for ERC-7579 accounts:

• Session key management
• Policy-based access control
• ERC-1271 signature validation
• Batched execution support

WebAuthn Validators

WebAuthn2/FIDO2 authentication implementation:

• ECDSA P256 optimization
• FreshCryptoLib integration
• Gas-optimized verification
• Comprehensive test coverage
