CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our development lifecycle includes formal verification, gas optimization, and comprehensive testing to ensure security and efficiency.

From token standards to complex DeFi logic, we deliver audited code that powers your product.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and staking.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
  • Enterprise Logic: Multi-signature wallets, DAO governance modules, and cross-chain bridges.
  • Deliverables: Full test suites, deployment scripts, technical documentation, and audit readiness reports.

ENGINEERED FOR SCALE

Core Technical Capabilities

Our EVM yield vault development is built on a foundation of battle-tested security, modular architecture, and deep protocol integration. We deliver production-ready systems that generate sustainable yield from day one.

01

Secure Smart Contract Architecture

We build with Solidity 0.8+ using OpenZeppelin libraries and implement a multi-layered security model. Every vault undergoes rigorous internal review and formal verification to protect user assets.

AUDIT-READY FROM DAY ONE

Our Security-First Development Process

Every EVM yield vault we build is engineered for security and resilience. Our battle-tested process, refined over 50+ deployments, ensures your protocol is robust, efficient, and ready for mainnet launch.

01

Architecture & Threat Modeling

We begin with a formal threat model, identifying attack vectors like reentrancy, flash loan exploits, and oracle manipulation. This proactive approach defines security boundaries and informs the entire design.

Frequently Asked Questions

Get clear answers on timelines, security, and process for building institutional-grade yield vaults.

A standard, audited yield vault with core strategies (e.g., staking, lending pool deposits) is typically delivered in 4-6 weeks. Complex multi-strategy vaults with custom logic or cross-chain components can take 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
