CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
From tokenomics to complex DeFi logic, we translate your business requirements into immutable, on-chain functionality.
- Protocol Development: Custom
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and governance systems.
- Security First: Development with
OpenZeppelinlibraries, comprehensive unit testing, and pre-audit code reviews. - Full Lifecycle: We handle deployment, verification on Etherscan, and initial integration support.

THE BUSINESS CASE
Why Choose a Modular SDK Over a Custom Build
Building a custom wallet stack from scratch is a high-risk, resource-intensive endeavor. Our modular SDK provides a proven, secure, and scalable foundation, allowing your team to focus on your unique product vision and user experience.
01
Accelerate Time-to-Market
Deploy a production-ready smart wallet infrastructure in weeks, not months. Our pre-audited modules for account abstraction, gas sponsorship, and session keys eliminate 80% of the foundational development work.
