overview
FULL-STACK ENGINEERING

Custom Blockchain Development

End-to-end development of secure, scalable blockchain applications tailored to your business logic.

We architect and build production-ready blockchain solutions from the ground up. Our full-cycle development delivers custom smart contracts, decentralized applications (dApps), and enterprise-grade protocols designed for real-world use.

From concept to mainnet, we ensure your application is secure, performant, and ready to scale with your user base.

  • Core Development: Solidity/Rust smart contracts, EVM/Solana/Cosmos dApps, and Layer 2 integrations.
  • Security First: All code undergoes rigorous internal review and third-party audits with firms like CertiK or Quantstamp.
  • Measurable Outcomes: Typical delivery includes a fully audited MVP in 4-6 weeks with 99.9% uptime SLAs for core infrastructure.

Blockchain Migration FAQs for NeoBank Leaders

Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a blockchain migration partner.

Our standard migration process takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture review and planning, 2-4 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. For complex, multi-chain neobank architectures with custom DeFi modules, timelines may extend to 12 weeks. We provide a detailed, phase-gated project plan in our initial proposal.
