Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our development process ensures security-first design, gas optimization, and comprehensive testing before mainnet deployment.
ERC-20, ERC-721, ERC-1155, ERC-4626, and custom standards.Reduce your time-to-market from months to weeks with our battle-tested development framework.
Our engineers deliver modular, upgradeable contracts using patterns like the Transparent Proxy and UUPS. We focus on long-term maintainability and composability within the broader DeFi ecosystem, ensuring your protocol integrates seamlessly with existing infrastructure.
Our StarkNet Cairo Multi-Sig Account Abstraction service delivers secure, scalable, and developer-friendly infrastructure. We focus on production-grade reliability and seamless integration to accelerate your go-to-market timeline.
Our StarkNet Cairo Multi-Sig Account Abstraction service delivers concrete, measurable results that accelerate your product roadmap and de-risk your launch.
Production-ready multi-signature smart accounts deployed on StarkNet Mainnet. Built with Cairo 1.0, featuring customizable signing policies, social recovery, and OpenZeppelin-audited security patterns.
Implement gasless transactions and fee sponsorship models. We configure paymasters to let users transact without holding ETH, removing a major UX barrier for mainstream adoption.
Enable users to bundle multiple actions (swap, stake, transfer) into a single transaction. This reduces network load, cuts total gas costs, and creates a seamless app-like experience.
Deploy session key systems for time-bound, permission-scoped automation. Allows for automated trading, subscription payments, and game interactions without constant wallet confirmations.
Complete integration with your dApp frontend (React/Next.js) and backend. Includes a comprehensive SDK, API hooks, and documentation for your team to manage and extend the system.
