overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific use case and audited for deployment.

We architect and deploy custom smart contracts that are secure by design. Our development process integrates formal verification and automated testing from day one, ensuring your core business logic is resilient against exploits before mainnet launch.

Deliver a market-ready product in 4-6 weeks, from specification to audited deployment on your chain of choice.

  • Protocol Development: Custom ERC-20, ERC-721, staking systems, DAO governance, and DeFi primitives.
  • Security First: Built with OpenZeppelin libraries and patterns, followed by third-party audit coordination.
  • Full Lifecycle Support: From initial design and optimization to post-deployment monitoring and upgrade management.

Frequently Asked Questions

Get clear answers on timelines, costs, and technical details for building a custom identity subgraph.

A portable identity subgraph aggregates and indexes on-chain identity data (like ENS names, social profiles, DAO memberships, and credential attestations) from multiple sources into a single, queryable API endpoint. You need one to build features like user profiles, reputation-based access, and personalized dashboards without the complexity of managing raw blockchain data. We've built subgraphs securing over $500M in TVL for identity and DeFi protocols.
