Private Interoperability Protocol Development

We design and implement custom cross-chain messaging and state-sharing protocols with privacy guarantees, enabling your dApp to operate confidentially across multiple blockchain ecosystems.
Chainscore © 2026
overview
FULL-STACK BUILD

Custom Blockchain Development

End-to-end blockchain solutions from smart contracts to user-ready applications.

We architect and build complete, production-ready blockchain systems. Our full-stack approach delivers secure, scalable, and maintainable applications, not just isolated contracts. We handle everything from the core protocol layer to the user interface.

Go from concept to mainnet in weeks, not months, with our battle-tested development framework.

  • Smart Contract Development: Custom Solidity/Rust contracts with OpenZeppelin standards and formal verification.
  • Backend & APIs: Scalable indexers (The Graph), secure relayers, and real-time data pipelines.
  • Frontend Integration: Seamless web3.js/ethers.js integration, wallet connectivity, and responsive dashboards.
  • Deployment & DevOps: Automated CI/CD, multi-chain deployment strategies, and 24/7 monitoring with alerting.

Frequently Asked Questions

Get clear answers about our development process, timelines, security, and support for building secure cross-chain bridges and messaging layers.

A standard private bridge or cross-chain messaging layer takes 4-8 weeks from design to mainnet deployment. This includes 1-2 weeks for architecture and threat modeling, 2-4 weeks for core smart contract and relayer development, and 1-2 weeks for internal audits and testing. Complex multi-chain deployments or custom consensus mechanisms can extend this timeline. We provide a detailed project plan with milestones during the initial consultation.
