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 tailored to your business logic. Our full-stack approach ensures seamless integration from the protocol layer to the user interface.

  • Smart Contract Development: Secure, gas-optimized contracts in Solidity, Rust (Solana), or Move (Aptos/Sui).
  • Backend & Indexing: Custom Node.js/Python backends with real-time data indexing via The Graph or proprietary solutions.
  • Frontend & Wallets: React-based dApps with seamless MetaMask, WalletConnect, and embedded wallet integration.
  • Deployment & DevOps: Automated CI/CD pipelines, multi-chain deployment, and infrastructure management on AWS/GCP.

We deliver a fully functional, audited MVP in 4-6 weeks, complete with documentation and a clear path to mainnet launch.

Our development process is built on enterprise-grade security practices, including mandatory peer reviews and integration with leading audit firms before deployment.

BUILT FOR PRODUCTION

Core Technical Capabilities

Our stealth bridge development delivers enterprise-grade infrastructure with verifiable security and performance. We focus on the technical depth that CTOs and lead developers require for mission-critical cross-chain applications.

01

Zero-Knowledge Proof Integration

We implement ZK-SNARKs and ZK-STARKs for transaction privacy, ensuring sender, receiver, and amount remain confidential across chains. Built with industry-standard libraries like Circom and Halo2 for verifiable security.

Frequently Asked Questions

Get clear answers on development timelines, security, costs, and support for your private cross-chain bridge project.

A production-ready stealth bridge from concept to mainnet typically takes 6-10 weeks. This includes 2 weeks for architecture and design, 3-4 weeks for core development and integration, 1-2 weeks for internal security review, and 2 weeks for client testing and deployment. Complex multi-chain architectures or custom privacy mechanisms can extend this timeline.
