overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect, develop, and deploy custom Solidity and Rust smart contracts for DeFi, NFTs, and enterprise applications. Our process ensures security-first development, gas optimization, and full audit readiness from day one.

Deploy with confidence, backed by formal verification and battle-tested patterns.

  • Custom Logic: Build unique tokenomics, governance systems, and automated workflows.
  • Security Audits: Integrated OpenZeppelin libraries and pre-audit code reviews.
  • Gas Efficiency: Optimized for cost, targeting up to 40% lower transaction fees.
  • Full Deployment: End-to-end support from testnet to mainnet on EVM or Solana.

We deliver production-grade contracts in 2-4 weeks, complete with comprehensive documentation and integration guides. Avoid costly exploits and launch delays with our expert-led development cycle.

  • DeFi Protocols: Automated Market Makers (AMMs), liquidity pools, staking mechanisms, and yield aggregators with gas-optimized logic.
  • Enterprise Logic: Multi-signature wallets, access control systems, and upgradeable proxy patterns for long-term maintainability.
  • Full Audit Trail: Every contract undergoes peer review and automated analysis before delivery, with optional integration with top-tier audit firms.

We deliver a secure, documented codebase in 2-4 weeks, enabling you to launch your core product with confidence and a clear path for future iteration.

Technical Deep Dive

Frequently Asked Questions on Data Availability Proofs

Get clear, expert answers to the most common technical and commercial questions about implementing and operating a secure, cost-effective Data Availability layer for your rollup.

A custom Data Availability (DA) system provides predictable costs, enhanced privacy, and protocol-specific optimizations. While public layers like Ethereum offer security, their costs are volatile and data is public. Our solutions can reduce your operational DA costs by 60-90% versus posting all data to Ethereum L1, while enabling features like encrypted data for private transactions or optimized data structures for your specific state transitions.
