Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development lifecycle includes:
ERC-20, ERC-721, and custom standards for tokens, NFTs, and DeFi protocols.From initial concept to mainnet launch, we manage the entire development pipeline, delivering a production-ready MVP in as little as 4 weeks.
Our engineers specialize in Solidity, Rust (Solana), and Vyper, implementing proven patterns from OpenZeppelin and industry best practices to mitigate risks like reentrancy and front-running.
Our infrastructure is engineered for secure, scalable, and compliant cross-ecosystem asset movement, built on verifiable security practices and battle-tested protocols.
Deploy confidential, cross-chain asset transfers that directly enhance your platform's security, user trust, and competitive edge.
Integrate ZK-SNARKs or ZK-STARKs to enable private transactions and shielded balances. Protect user data and transaction patterns from public blockchain exposure, meeting stringent compliance requirements for institutional clients.
Connect to aggregated liquidity pools across Ethereum, Solana, Cosmos, and other major L1/L2 networks. Enable single-transaction swaps between any supported asset without fragmenting user funds.
Build with embedded Travel Rule (FATF) compliance, on-chain attestations, and configurable sanctions screening. Our modular architecture adapts to evolving global regulations without core protocol changes.
Achieve deterministic transaction settlement with 99.9% uptime SLAs. Our relay network and optimistic execution ensure transfers complete in under one second, critical for trading and payment applications.
Deploy with confidence using formally verified circuits and smart contracts. Every component undergoes third-party audits by firms like Trail of Bits and OpenZeppelin before production release.
Cut 6-12 months off your development timeline with our pre-built, modular SDKs. Eliminate the overhead of maintaining cross-chain validators, privacy circuits, and compliance engines in-house.

A structured, transparent approach designed to deliver secure, scalable, and production-ready confidential transfer systems. We focus on rapid iteration and measurable outcomes, from initial design to mainnet deployment.
We begin with a security-first architecture review and threat model for your cross-chain asset flow. This defines the cryptographic primitives (ZKPs, MPC, TEEs), key management strategy, and risk mitigation plan before a single line of code is written.
Development of core smart contracts for asset locking, verification, and release, alongside off-chain relayers or prover nodes. Built with Solidity 0.8+ and Rust, using OpenZeppelin libraries and industry-standard cryptographic libraries.
Every component undergoes rigorous third-party security audits from firms like Trail of Bits or Quantstamp. Critical logic is formally verified using tools like Certora Prover to mathematically prove correctness against our specifications.
Full deployment to a staging environment mirroring production, followed by integration on testnets (Sepolia, Holesky, Arbitrum Sepolia). We conduct end-to-end integration testing, load testing, and failure scenario simulations.
Managed mainnet deployment with automated scripts and multi-sig governance. We implement comprehensive monitoring with Prometheus/Grafana dashboards, alerting for bridge health, latency, and security events.
We deliver complete technical documentation, operational runbooks, and admin key training. The final handover ensures your team has full operational control and understanding of the system's architecture and emergency procedures.
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our engineers specialize in Solidity 0.8+ and Rust, following OpenZeppelin standards and implementing comprehensive security patterns from day one.
From tokenomics to complex DeFi logic, we turn your requirements into auditable, on-chain code.
Get clear answers on how we build secure, private bridges for your multi-chain strategy.
From initial design to mainnet deployment, a standard confidential cross-chain bridge takes 6-10 weeks. This includes 2 weeks for architecture and ZKP circuit design, 3-4 weeks for core smart contract and relayer development, and 2-3 weeks for comprehensive security audits and testing. Complex multi-asset or custom consensus mechanisms can extend this timeline.
