Privacy-Preserving Cross-Chain Transfer Protocol

We implement zk-SNARKs and zk-STARKs to enable private transaction validation. Shield sensitive transfer amounts and participant identities without compromising on-chain verifiability or regulatory compliance.

Decentralized, fault-tolerant network of relay nodes using threshold signatures. Eliminates single points of failure for message passing and ensures liveness even with up to 1/3 of nodes offline or malicious.

Protocol-agnostic bridge supporting EVM, Cosmos IBC, Solana, and Bitcoin. We handle the underlying adapter logic, allowing you to transfer assets and arbitrary data across any connected chain with a single integration.

Deploy custom, audited mixer contracts for asset obfuscation. Our architecture separates the deposit/withdrawal logic from the proof verification, enabling scalable privacy sets and compliance with OFAC sanctions lists.

Light client proofs and optimistic verification modules that confirm the validity of cross-chain state in under 2 seconds. Drastically reduces the trust assumptions compared to traditional bridge models.

Critical protocol logic is specified in TLA+ and verified with tools like Certora and K-framework. We provide audit reports from Trail of Bits and OpenZeppelin for all production deployments.

We design a custom protocol architecture using zero-knowledge proofs (ZK-SNARKs/STARKs) or secure multi-party computation (sMPC) tailored to your asset types and compliance needs. This phase establishes the cryptographic foundation for privacy and interoperability.

Development of core smart contracts (Solidity/Rust) and zero-knowledge circuits (Circom, Noir) for verifiable private transfers. All code follows OpenZeppelin patterns and is optimized for gas efficiency and auditability.

Comprehensive security review by internal experts and leading third-party auditors like Trail of Bits or Quantstamp. We include formal verification for critical circuit logic to mathematically prove correctness.

Deployment of decentralized relayers, indexers, and monitoring dashboards. We provision infrastructure with 99.9% uptime SLA, ensuring low-latency cross-chain message passing and real-time health checks.

We provide lightweight SDKs (TypeScript/Go) and comprehensive API documentation for seamless integration into your existing wallet, dApp, or exchange platform, enabling private transfers in days, not months.

Post-launch support including protocol upgrades, new chain integrations (EVM, Cosmos, Solana), and 24/7 incident response. We ensure your protocol remains secure and compatible with ecosystem evolution.
