Privacy-Preserving Stablecoin Transfer Protocol

We implement zk-SNARKs to enable private transfers where only the sender and receiver can view transaction amounts and recipient addresses. Balances and transaction graphs are cryptographically hidden on-chain, meeting the privacy standards of institutional finance.

Built-in compliance hooks for licensed VASPs. Our protocol supports selective disclosure to regulators via viewing keys and integrates with travel rule solutions, enabling private-by-default transactions that can be audited when legally required.

Optimized batch processing and efficient proof verification to support thousands of private transactions per second. Our architecture minimizes on-chain gas costs while maintaining sub-2 second finality for shielded transfers.

Production-ready TypeScript/Go SDKs and REST APIs for wallet integration, transaction construction, and proof generation. We handle the cryptographic complexity, providing simple transferPrivate() and viewBalance() methods for your application.

Every component undergoes rigorous security assessment. Our smart contracts are audited by leading firms, our cryptographic circuits are formally verified, and we implement multi-party computation for trusted setup ceremonies to eliminate single points of failure.

Deploy your private stablecoin protocol across Ethereum, Polygon, Arbitrum, and other EVM-compatible networks. Our architecture uses canonical bridging with message passing to maintain privacy guarantees across chains.

Leverage zk-SNARKs for transaction privacy with on-chain verifiability. We implement Plonky2 or Halo2 circuits for optimal gas efficiency and proof generation speed, ensuring privacy without compromising network performance.

Core protocol logic is formally verified using tools like Certora Prover or K-Framework, providing mathematical guarantees against reentrancy, overflow, and logic flaws beyond standard auditing.

Every deployment undergoes rigorous scrutiny by Trail of Bits, Quantstamp, or OpenZeppelin. We maintain a public audit repository and implement a structured bug bounty program via Immunefi.

Built-in Travel Rule (FATF) compliance via zero-knowledge proofs of compliance. Supports selective disclosure to regulators without exposing entire transaction graphs, integrating with providers like Notabene or VerifyVASP.

Decentralized, fault-tolerant relayers manage proof generation and submission with 99.95% SLA. Automated failover and geographic distribution ensure transaction finality even during regional outages.

Contracts are written in Solidity 0.8.23+ with Yul optimizations. ZK circuits are hand-optimized for minimal constraints. We deliver up to 40% lower gas costs versus baseline implementations.
