CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security from the first line of code. We deliver contracts for ERC-20, ERC-721, ERC-1155, and complex DeFi logic with formal verification and gas optimization.
From a 2-week MVP to a full protocol suite, we build for security, scalability, and seamless integration.
- Security-First Development: Rigorous internal audits, property-based testing with
Foundry, and adherence to industry best practices before external review. - Full-Stack Integration: Contracts designed to work with your frontend and backend, including event indexing and off-chain computation.
- Ongoing Support: Post-deployment monitoring, upgradeability planning, and maintenance for long-term protocol health.
Technical Deep Dive
DID Integration: Common Questions from Technical Leaders
Answers to the most frequent technical and operational questions from CTOs and engineering leads evaluating DID solutions.
Standard DID integration for a Web3 application takes 2-4 weeks from kickoff to production deployment. This includes architecture design, smart contract development, frontend SDK integration, and security review. Complex enterprise integrations with custom attestation schemas or multi-chain support typically extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
