overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built for security and speed, delivering a production-ready MVP in 2-4 weeks.

  • Security-First Development: Built with Solidity 0.8+ and OpenZeppelin libraries, following industry-standard patterns.
  • Full Audit Support: Contracts are developed with formal verification in mind and prepared for third-party audits from firms like CertiK or Quantstamp.
  • Gas Optimization: We write efficient code to minimize transaction costs for your users, a critical factor for adoption.

Our team specializes in the core protocols that power modern dApps:

  • Token Standards: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like minting, burning, and royalties.
  • DeFi Primitives: Staking pools, liquidity vaults, automated market makers (AMMs), and lending/borrowing logic.
  • Governance Systems: ERC-20 or ERC-721 based DAO frameworks with proposal and voting mechanisms.

We don't just write code; we deliver the secure, auditable financial infrastructure your product needs to launch with confidence.

Staged Implementation for Controlled Development

A phased approach to deploying Account Abstraction for regulatory compliance, allowing you to validate core functionality, integrate with existing systems, and scale with confidence.

Implementation PhaseFocus & DeliverablesTimelineKey Outcomes

Phase 1: Foundation & Audit

Core AA smart contracts (ERC-4337), initial security audit, basic paymaster setup, testnet deployment.

2-4 weeks

Secure, audited contract foundation. Ready for internal testing and compliance review.

Phase 2: Integration & Pilot

Integration with your existing KYC/AML stack, custom policy rules engine, first regulatory wallet prototype, limited user pilot.

3-6 weeks

Functional pilot with real compliance logic. Validated user flows and initial performance data.

Phase 3: Production Launch

Mainnet deployment, full monitoring & alerting suite, disaster recovery plan, advanced paymaster strategies (sponsorship, gasless).

2-3 weeks

Fully operational, compliant wallet system. Ready for public or whitelisted user onboarding.

Phase 4: Scale & Optimize

Multi-chain deployment (Polygon, Base, etc.), performance optimization, advanced analytics dashboard, SLA-backed support.

Ongoing

Scalable, multi-chain infrastructure with proven reliability and detailed user insights.

Typical Total Timeline

From contract to controlled mainnet launch

7-13 weeks

Dramatically faster than 6-12 month in-house builds, with expert guidance at each step.
