ERC-4337 Privacy Wallet Dev

About

This skill provides specialized guidance and implementation patterns for building ERC-4337 compliant smart contract wallets that prioritize on-chain privacy. It enables developers to protect sensitive identifiers like license plates and biometric data using commitment schemes and deterministic address generation (CREATE2), ensuring private information remains off-chain while maintaining full wallet functionality. It is particularly useful for building secure vehicle registries, identity-linked accounts, and privacy-centric Web3 applications that require robust security audits and automated validation.

Key Features

• Off-chain commitment scheme implementation to hide sensitive identifiers
• Comprehensive testing suites for ERC-4337 UserOperation validation and privacy verification
• Deterministic address generation for predictable, counterfactual deployments
• 1 GitHub stars
• Privacy-protected ERC-4337 smart contract templates for accounts and factories
• Automated privacy validation scripts to detect potential data leaks in contracts

Use Cases

• Creating biometric-linked accounts with secure off-chain commitment verification
• Implementing vehicle-specific wallets that hide license plate numbers from public ledgers
• Building privacy-preserving identity registries with zero-knowledge proof integration
