overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built for security-first, with formal verification and comprehensive audits by firms like Quantstamp and CertiK.

Deliver a market-ready product in 4-6 weeks, not months, with battle-tested code patterns.

  • Token Standards: ERC-20, ERC-721, ERC-1155, SPL, and custom implementations.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators.
  • Enterprise Logic: Multi-signature wallets, vesting schedules, and governance modules.
  • Full Lifecycle: Development, deployment, monitoring, and upgrade management via proxies.

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 application. Our development process ensures security-first design, gas optimization, and regulatory compliance from day one.

  • Security Audits: Every contract undergoes rigorous review using Slither, MythX, and manual inspection before deployment.
  • Standard Compliance: Built on OpenZeppelin libraries with custom extensions for ERC-20, ERC-721, ERC-1155, and ERC-4626.
  • Gas Efficiency: Optimized logic to reduce user transaction costs by up to 40% versus unaudited code.

Deliver a secure, audited, and fully functional smart contract suite in as little as 4 weeks, from specification to mainnet deployment.

Frequently Asked Questions

Get clear answers on our development process, timelines, and security for your custom StarkNet Cairo verifiable pricing engine.

A verifiable pricing engine is a smart contract system that calculates and attests to asset prices on-chain in a cryptographically provable way. On StarkNet, using Cairo, this enables trustless, high-frequency price feeds for DeFi protocols like perpetuals, options, and lending markets. It eliminates reliance on centralized oracles, reduces latency, and provides mathematical proof of correct calculation, which is critical for security and capital efficiency.
