overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
Deliver a market-ready, secure contract suite in as little as 2-4 weeks, not months.
- Full Lifecycle Development: From ideation and architecture to deployment on
EVMchains (Ethereum,Polygon,Arbitrum) and mainnet launch support. - Security-First Approach: Every contract undergoes internal audits against common vulnerabilities (reentrancy, overflow) before we recommend third-party review.
- Clear Deliverables: You receive comprehensive documentation, verification on Etherscan, and a full test suite ensuring long-term maintainability.

Smart Wallet Development: Common Questions
Answers to the most frequent technical and commercial questions we receive from CTOs and product leads evaluating smart wallet development partners.
For a standard Account Abstraction (ERC-4337) mobile smart wallet with core features (social login, gas sponsorship, batch transactions), we deliver a production-ready MVP in 4-6 weeks. Complex projects with custom modules (multi-PKI, advanced recovery, institutional features) typically take 8-12 weeks. Our agile sprints ensure you have a working prototype for user testing within the first 2 weeks.
