overview
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 for DeFi, NFTs, and enterprise applications. Our development process ensures security-first code, gas optimization, and full audit readiness from day one.

  • End-to-End Development: From ideation and architecture to deployment and maintenance on EVM or Solana.
  • Security as Standard: Built with OpenZeppelin libraries and rigorous internal review for zero critical vulnerabilities.
  • Proven Patterns: Implementation of established standards like ERC-20, ERC-721, and custom logic for complex protocols.

Reduce your time-to-market from months to weeks with our battle-tested development framework.

Our deliverables include:

  • Production-ready code with comprehensive documentation and test suites.
  • Gas efficiency reports to minimize user transaction costs.
  • A clear path to third-party audits with firms like CertiK or Quantstamp.

PROVEN FRAMEWORK

Our Migration Methodology

A systematic, risk-mitigated approach to transitioning from legacy systems or Web2 platforms to a scalable, interoperable metaverse architecture. We ensure zero data loss and minimal business disruption.

01

Discovery & Architecture Audit

We conduct a comprehensive analysis of your existing systems, data models, and business logic. This phase defines the target state, selects optimal protocols (e.g., EVM, Solana), and creates a detailed migration blueprint.

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.

We architect and deploy production-grade Solidity and Rust contracts for DeFi, NFTs, and enterprise applications. Our development process is built on OpenZeppelin standards and formal verification to eliminate critical vulnerabilities before a single line of code is deployed.

  • Custom Logic: Build unique tokenomics, governance systems, and automated market makers.
  • Security-First: Every contract undergoes manual review and automated analysis with tools like Slither and MythX.
  • Gas Optimization: We write efficient code to minimize transaction fees, a critical factor for user adoption.
  • Full Lifecycle: From initial spec and Hardhat/Foundry testing to deployment scripts and on-chain verification.

We deliver contracts you can stake your reputation on. Our code has secured over $500M+ in TVL across client projects with zero critical vulnerabilities post-audit.

Typical deliverables include audit-ready source code, comprehensive test suites, deployment guides, and post-launch monitoring setup. Get from concept to a secure mainnet launch in as little as 4-6 weeks.

Technical & Commercial Questions

Metaverse Migration FAQs

Answers to the most common questions from CTOs and product leads planning a migration to the metaverse or upgrading legacy virtual environments.

A standard migration for a medium-complexity virtual world (e.g., Unity-based game, simple 3D platform) takes 4-8 weeks from kickoff to live deployment. This includes architecture design, smart contract development, asset tokenization, and integration. Complex ecosystems with custom economics or VR integration can extend to 12-16 weeks. We provide a detailed, phased project plan in week one.
