CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect, develop, and deploy custom smart contracts that are secure by design and gas-optimized. Our process delivers audit-ready code from day one, reducing time-to-market and mitigating critical risks.

  • Protocols & Standards: ERC-20, ERC-721, ERC-1155, ERC-4626, and custom logic.
  • Security First: Built with OpenZeppelin libraries and formal verification patterns.
  • Deliverables: Full test suites, deployment scripts, and technical documentation.

We deliver contracts you can trust, with a focus on mainnet resilience and long-term maintainability.

PROVEN METHODOLOGY

Our Secure, Iterative Development Process

We build and integrate secure browser extension wallets using a phased, client-focused approach that minimizes risk and accelerates your time-to-market.

01

Architecture & Threat Modeling

We begin with a comprehensive security-first design, analyzing attack vectors for your specific use case (DeFi, NFT, payments). This includes defining key storage, transaction signing flows, and permission models to prevent common vulnerabilities.

Frequently Asked Questions on Wallet Integration

Get clear answers on timelines, security, and process for integrating a secure, user-friendly browser extension wallet into your Web3 application.

A standard, production-ready browser extension wallet integration takes 4-6 weeks from kickoff to deployment. This includes architecture, core wallet functionality (key management, transaction signing), multi-chain support, and security audits. Complex features like MPC, account abstraction, or custom DeFi integrations can extend the timeline to 8-12 weeks. We provide a detailed project plan with milestones in the first week.
