Furthermore, it was an app that you had to decide and remember to use, in a moment of crisis. With ProofMode, we both wanted to simplify the adoption of the tool, and make it nearly invisible to the end-user, while making it the adoption of the tool by organizations painless through simple formats like CSV and known formats like PGP signatures. +# ✨ NEW: Web3 Wallet Integration + +This version of ProofMode includes Web3 wallet authentication through Privy SDK integration, enabling users to securely authenticate and manage cryptographic wallets alongside their proof data. + +## Features + +- **SMS/Email OTP Authentication**: Secure phone number and email verification using Privy's authentication system +- **Embedded Wallet Creation**: Automatic Ethereum wallet generation for authenticated users +- **Cross-Platform Ready**: Implementation designed to match iOS patterns for future consistency +- **Secure Key Management**: Wallet addresses and authentication state managed through encrypted storage + +## Setup + +To enable Web3 wallet functionality: + +1. **Configure Privy Credentials**: + - Open `app/src/main/java/org/witness/proofmode/crypto/privy/PrivyConfig.kt` + - Add your Privy `APP_ID` and `APP_CLIENT_ID` from your Privy dashboard + +2. **Dependencies**: + - The required Privy SDK dependency is already included in `app/build.gradle` + - No additional setup required + +## Usage + +Users can access Web3 wallet features through the new "Web3 Wallet" option in the app, allowing them to: +- Authenticate using phone number or email with OTP verification +- Generate and manage embedded Ethereum wallets +- View wallet addresses and connection status +- Securely logout and disconnect wallets + +## Implementation Details + +- **PrivyManager.kt**: Core wallet management and authentication logic +- **PrivyConfig.kt**: Configuration for Privy SDK credentials +-

Guide](docs/web3-wallet-setup.md)**: Step-by-step configuration and troubleshooting +- **[Technical Documentation](docs/web3-wallet-integration.md)**: Architecture details and implementation notes +
