StarkNet ZK-Proofs for Private Training

We develop custom zk-STARK systems on StarkNet to provide cryptographic proof of correct AI model training while keeping the underlying data and model updates confidential.

overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built for production by senior Solidity engineers.

We architect and deploy custom smart contracts that form the backbone of your protocol. Our senior engineers write in Solidity 0.8+ with OpenZeppelin standards, delivering audit-ready code from day one.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance.
  • DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking mechanisms, and yield aggregators.
  • Enterprise Logic: Multi-signature wallets, access control, upgradeable proxy patterns, and cross-chain bridges.

We focus on security and efficiency, implementing formal verification and gas optimization to reduce deployment costs by up to 40% and mitigate exploit risks.

Our process includes comprehensive unit testing with Hardhat/Foundry, integration testing on testnets, and preparation for third-party audits from firms like CertiK or Quantstamp.
