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 foundation of your dApp. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.
- DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators.
- NFT Ecosystems: ERC-721A, ERC-1155 marketplaces with advanced minting logic.
- Enterprise Logic: Custom business rules, multi-signature wallets, and governance systems.
We deliver battle-tested code with a 99.9% uptime SLA and zero critical vulnerabilities post-audit.
Our engineers use Solidity 0.8+, Hardhat/Foundry, and OpenZeppelin libraries. Every contract undergoes static analysis, unit/integration testing, and a formal review for EIP compliance before deployment to Mainnet.
Typical Deliverables:
- Production-ready source code with full documentation.
- Deployment scripts and verification for Etherscan.
- Security audit report from a partnered firm.
- Post-launch monitoring and incident response plan.
Outcome: Reduce your time-to-market by 60% and mitigate the risk of exploits that can cost millions.

Frequently Asked Questions
Get clear answers on how our specialized wallet development service works, from security to integration.
For a standard stealth messaging wallet with core AA features, deployment typically takes 3-5 weeks. This includes smart contract development, integration with privacy protocols (like Semaphore or ZK proofs), and frontend/backend setup. Complex requirements like custom governance or multi-chain support can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
