overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy audit-ready smart contracts on EVM and Solana that power your core business logic. Our development process is built for security-first deployment and long-term maintainability.

  • Custom Logic: Tailored Solidity 0.8+ or Rust contracts for DeFi, NFTs, DAOs, and enterprise applications.
  • Security by Design: Implementation of OpenZeppelin standards, formal verification patterns, and comprehensive unit/integration testing.
  • Gas Optimization: Expert-level tuning to reduce deployment and transaction costs by up to 40%.

From initial spec to mainnet launch, we deliver contracts you can stake your business on.

Our full-cycle service includes:

  • Technical Specification & Architecture: Defining invariants, upgrade paths, and failure modes.
  • Development & Internal Audit: Peer-reviewed code with simulated attack vectors.
  • Third-Party Audit Coordination: We manage the process with leading firms like CertiK or Quantstamp.
  • Deployment & Monitoring: Secure mainnet deployment with 24/7 monitoring for anomalous activity.

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 product. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and rigorous audit patterns to mitigate risk from day one.

  • Full Lifecycle Development: From ideation and Solidity 0.8+ coding to deployment on EVM/L2s and post-launch maintenance.
  • Compliance & Standards: Built-in support for ERC-20, ERC-721, ERC-1155, and custom tokenomics with regulatory considerations.
  • Gas Optimization: Every contract is optimized for minimum gas consumption, reducing end-user transaction costs by up to 40%.
  • Integration Ready: Contracts are designed for seamless integration with your frontend and backend systems.

We deliver battle-tested contracts with a 99.9% security audit pass rate, enabling you to launch with confidence in weeks, not months.

Frequently Asked Questions

Get clear answers about our SDK development process, security, and support.

A standard, production-ready Multi-Chain SDK is typically delivered in 4-6 weeks. This includes design, core development, testing, and documentation. Complex integrations (e.g., custom oracles, novel consensus modules) can extend this to 8-12 weeks. We provide a detailed project plan with milestones during the initial scoping phase.
