overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy audited, gas-optimized smart contracts that form the backbone of your Web3 product. Our development process ensures security-first design and maintainable code from day one.

Deploy with confidence. Our contracts undergo rigorous internal review and third-party audits before mainnet launch.

Our development stack includes:

  • Solidity 0.8+ & Vyper for EVM chains (Ethereum, Polygon, Arbitrum).
  • Rust & Anchor for Solana high-performance programs.
  • OpenZeppelin libraries and custom security patterns.
  • Foundry & Hardhat for comprehensive testing and simulation.

Deliverables you receive:

  • Production-ready code with full test coverage and documentation.
  • Gas optimization report detailing cost-saving strategies.
  • Deployment scripts & verification for Etherscan/Solscan.
  • Post-launch monitoring and upgrade pathway planning.

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy audit-ready smart contracts on EVM-compatible chains like Ethereum, Polygon, and Arbitrum. Our development process is built on OpenZeppelin standards and rigorous internal security reviews, ensuring your core logic is robust from day one.

Deliver a secure, functional MVP in as little as 2-4 weeks, accelerating your time-to-market while mitigating technical risk.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 implementations with advanced features like vesting, minting controls, and governance hooks.
  • DeFi Primitives: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending protocols with optimized gas efficiency.
  • Upgradeable Architecture: Proxies and diamond patterns (EIP-2535) for seamless, secure future upgrades without migration.
  • Full Audit Support: Code is structured and documented for smooth handoff to leading security firms like CertiK or Quantstamp.

Frequently Asked Questions

Get clear answers on how our zero-knowledge verification services integrate with your compliance workflows, timelines, and security standards.

We implement zero-knowledge proofs (ZKPs) using industry-standard circuits (e.g., Circom, Halo2) to allow users to prove compliance (like KYC/AML status or accredited investor verification) without revealing the underlying sensitive data. The proof is verified on-chain by your smart contract, enabling permissioned access or transactions. We handle the entire stack: proof generation client-side, secure credential issuance, and on-chain verification contracts.
