Cross-Chain Data Asset Bridging

We develop secure, production-ready bridges and wrappers that enable data assets—licenses, streams, and access rights—to be traded and utilized across multiple blockchain ecosystems from a single DePIN marketplace interface.

FULL-STACK ENGINEERING

Custom Blockchain Development

Build, deploy, and scale custom blockchain networks and applications with expert engineering.

We architect and implement bespoke blockchain solutions from the protocol layer up. Our full-cycle development delivers production-ready networks, smart contracts, and dApps tailored to your specific business logic and regulatory requirements.

  • Layer 1/Layer 2 Development: Custom Substrate, Cosmos SDK, or OP Stack chains with your consensus, tokenomics, and governance.
  • Smart Contract Suites: Secure, gas-optimized contracts for ERC-20, ERC-721, ERC-1155, and custom standards, built with Solidity 0.8+ or Rust.
  • dApp & Backend Integration: Full-stack applications with React/Next.js frontends and Node.js/The Graph backends, connected via Web3.js/ethers.js.

We handle the entire stack so you can launch your core product in 6-8 weeks, not 6-8 months.

Every deployment includes formal verification, third-party audit coordination, and a 99.9% uptime SLA for node infrastructure. We build for scale from day one.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our contracts are built for real-world business logic, from tokenomics and DeFi protocols to NFT marketplaces and DAOs.

  • Security-First Development: Code is written in Solidity 0.8+ or Rust using OpenZeppelin libraries and undergoes rigorous internal audits before deployment.
  • Gas Optimization: We minimize transaction costs by 20-40% through efficient data structures and contract architecture.
  • Full Lifecycle Support: From initial spec and Hardhat/Foundry testing to mainnet deployment and upgrade management via transparent proxies.

Deliver a secure, auditable, and performant on-chain foundation for your product in as little as 4 weeks.

Cross-Chain Data Bridging

Frequently Asked Questions

Get clear answers on how we deliver secure, reliable bridges for your data assets, from NFTs to off-chain data feeds.

A standard deployment for a custom bridge connecting two EVM chains takes 4-6 weeks from kickoff to mainnet launch. This includes design, development, security audits, and testing. Complex multi-chain architectures or integration with non-EVM chains (e.g., Solana, Cosmos) may extend the timeline to 8-12 weeks. We provide a detailed project plan with milestones during the initial consultation.
