Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.
We architect and deploy custom smart contracts that are secure by design and gas-optimized. Our development process includes:
OpenZeppelin and Solmate.EVM-compatible chains.From initial concept to mainnet launch, we manage the entire lifecycle with a focus on security and long-term maintainability.
Our engineers specialize in Solidity 0.8+, Vyper, and Rust (for Solana). We deliver:
ERC-20, ERC-721, ERC-1155).Our infrastructure provides the cryptographic guarantees and operational reliability required for high-value, privacy-sensitive cross-chain applications. We deliver verifiable privacy without compromising on performance or security.
On-demand generation of succinct ZK proofs (zk-SNARKs/STARKs) for transaction privacy and state validity. Enables private asset transfers and confidential smart contract interactions across chains.
A standardized, extensible payload schema (based on IBC/CCTP principles) that supports private data, token transfers, and contract calls. Ensures interoperability across EVM, Cosmos, and Solana.
A decentralized network of incentivized relayers with economic security guarantees. Provides fast, reliable message delivery with sub-second finality confirmation for supported chains.
Application-layer encryption for message payloads using hybrid cryptography (symmetric + asymmetric). Data is encrypted at the source and only decryptable by the authorized destination contract.
Aggregate multiple ZK proofs into a single verifiable proof to drastically reduce on-chain verification costs and latency. Critical for scaling high-volume private messaging.
Privacy isn't just a feature—it's a strategic business enabler. Our zero-knowledge cross-chain messaging delivers measurable advantages for your protocol's security, compliance, and competitive edge.
Shield your users' cross-chain trades, liquidity movements, and asset transfers from front-running bots and MEV extraction. Our ZK-proofs conceal transaction details until settlement, securing your protocol's economic activity.
Build institutional-grade products with selective disclosure. Our architecture allows for verifiable compliance proofs (e.g., proof of accredited investor status, jurisdiction) without exposing underlying wallet histories.
Remove the friction and anxiety of public blockchain explorers. Users can interact with your dApp without exposing their full financial portfolio, lowering the barrier to entry and building deeper trust.
Adopt a privacy-by-design foundation that adapts to evolving global regulations. Our modular proof system lets you adjust privacy guarantees without costly protocol rewrites, ensuring long-term viability.
Differentiate your protocol in crowded DeFi and gaming verticals. Privacy becomes a unique selling proposition (USP) that attracts security-conscious users and institutional partners seeking discretion.
Enable private voting and proposal signaling across multiple chains. Protect voter identity and voting power from manipulation, ensuring more secure and authentic decentralized governance.

We deliver production-ready, privacy-first cross-chain messaging with a clear, phased approach. Our process is designed for technical leaders who need certainty, security, and a fast path to market.
We begin with a security-first architecture review, mapping data flows and identifying privacy risks. This phase includes defining zk-proof requirements, MPC protocols, and on-chain/off-chain trust boundaries to ensure your design is resilient from day one.
Our engineers build the core messaging layer using battle-tested libraries like libp2p for P2P networking and implement privacy primitives (zk-SNARKs, secure enclaves). We deliver modular, auditable code for relayers, light clients, and verifiers.
Every line of code undergoes rigorous review. We partner with leading firms like Trail of Bits and Certora for independent audits and use formal verification tools to mathematically prove the correctness of critical state transitions and privacy guarantees.
We deploy to a multi-chain testnet environment (Sepolia, Holesky, Arbitrum Sepolia) and execute comprehensive load testing. Our monitoring dashboards track latency, gas costs, and proof generation times to validate performance SLAs.
We manage the secure, phased mainnet rollout with automated fail-safes. This includes establishing decentralized relayer networks, configuring multi-sig governance for upgrades, and implementing secure key generation ceremonies for MPC participants.
Post-launch, we provide 24/7 monitoring, incident response, and regular protocol upgrades. Our team handles new chain integrations, performance optimizations, and stays ahead of evolving cryptographic standards to keep your system secure and competitive.

Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a private cross-chain messaging solution for their protocol.
For a standard implementation connecting 2-3 EVM chains, the typical timeline is 6-8 weeks. This includes architecture design, smart contract development, integration of privacy layers (like zero-knowledge proofs or secure multi-party computation), rigorous testing, and a final security audit. Complex multi-chain architectures or custom privacy primitives can extend this to 12+ weeks. We provide a detailed project plan within the first week of engagement.
