overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your decentralized applications.
We don't just write code; we deliver audited, gas-optimized systems that are secure by design.
- Security-First Development: All contracts follow
OpenZeppelinstandards and undergo rigorous internal review before third-party audits by firms like CertiK or Quantstamp. - Full-Stack Integration: We ensure seamless interaction between your contracts,
Node.js/Pythonbackends, andReact/Next.jsfrontends. - Ongoing Support: Post-deployment monitoring, upgrade path planning, and 24/7 incident response for critical protocols.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for custom blockchain authentication.
Our process is a structured 4-phase engagement: 1) Discovery & Scoping (1 week): We analyze your requirements for IBC compatibility, validator sets, and governance. 2) Architecture & Design (1-2 weeks): We design the module logic, define transaction types, and create security specs. 3) Development & Testing (3-5 weeks): We build the module using Rust (Substrate) or Go (Cosmos SDK), implement unit/integration tests, and conduct internal audits. 4) Deployment & Handoff (1 week): We assist with testnet deployment, provide documentation, and conduct knowledge transfer. We've delivered 50+ secure modules using this methodology.
