CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment and on-chain verification. - Security & Audits: Includes formal verification, unit testing with
Hardhat/Foundry, and preparation for third-party audits. - Gas Optimization: Every contract is optimized for minimum gas consumption, reducing user transaction costs by up to 40%.
- Upgradeability & Management: Implement upgradeable proxy patterns (
ERC-1967) and provide admin tools for secure contract management.
Deliver a secure, auditable, and high-performance smart contract foundation in as little as 3-4 weeks.

Frequently Asked Questions
Get clear answers on our process, timelines, security, and support for building your enterprise-grade verifiable credential issuance platform.
We deliver a fully functional, audited Minimum Viable Product (MVP) in 4-6 weeks. This includes core issuance, verification, and wallet integration. Full enterprise deployments with custom workflows, advanced revocation, and multi-chain support typically take 8-12 weeks. Timeline depends on the complexity of credential schemas, integration requirements, and desired compliance frameworks (e.g., W3C VC-DATA, EBSI).
