Void Wallet

Problem Statement

Financial privacy is a fundamental right, yet every transaction on Ethereum is publicly visible. Your salary, your investments, your trading strategies all exposed to competitors, surveillance firms, and the world. This transparency keeps $200B+ of institutional capital locked out of DeFi and forces individuals to sacrifice privacy for access. Existing privacy solutions are broken: Tornado Cash was sanctioned and is now unusable Pure ZK solutions are too expensive and struggle with scalability The market needs privacy that is scalable, compliant, and secure. That's exactly the problem Void Wallet aims to solve! 🔒

Void Wallet Solution

Void Wallet is a privacy-preserving wallet built on a hybrid architecture that combines Trusted Execution Environments (TEEs), Zero-Knowledge Proofs, and Sparse Merkle Trees to deliver confidential transactions at a fraction of the cost while giving users complete control over their compliance.

Confidential Computation with TEE: We leverage Oasis ROFL's Trusted Execution Environments to process transactions offchain in a secure enclave. This reduces costs compared to pure zero-knowledge solutions while maintaining cryptographic privacy guarantees.

User-Controlled Compliance with ZK Proofs: Each user generates secret keys that only they control in their local. When compliance is needed (e.g., "prove I didn't transact with address X"), users create zero-knowledge proofs without revealing their full transaction history or balance.

Cryptographic Safety Net with Sparse Merkle Trees: Every balance is committed to an onchain Merkle root. If the TEE infrastructure fails, users can generate their own Merkle proof and execute an emergency withdrawal, ensuring funds are never at risk.
