Cairo StarkNet Security Implementation

Provably secure smart contract development and verification for StarkNet. We ensure ZK-STARK circuit correctness and secure L1 Ethereum integration for your scalable dApp.
Chainscore © 2026
overview
CORE SERVICE

Custom Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic and audited for deployment.

We architect and deploy custom Solidity/Rust smart contracts that power your core product. Our process delivers audit-ready code in 2-4 weeks, integrating battle-tested patterns from OpenZeppelin and Solmate to mitigate reentrancy, overflow, and access control risks.

From tokenomics to complex DeFi logic, we translate your requirements into gas-efficient, upgradeable on-chain systems.

  • Token Standards: Custom ERC-20, ERC-721, ERC-1155 with minting, vesting, and governance modules.
  • DeFi & DAOs: Automated market makers (AMMs), staking pools, multi-signature treasuries, and voting systems.
  • Security First: Every contract undergoes internal review + formal verification tools before third-party audit.
