ZK-Rollup License Verification Implementation

Engineer scalable license verification systems using ZK-Rollup technology (zkSync, Starknet) to batch thousands of compliance checks off-chain while maintaining on-chain verifiable proof of validity.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect, develop, and audit custom smart contracts that form the immutable foundation of your protocol. Our team specializes in Solidity 0.8+ and Vyper, leveraging battle-tested libraries like OpenZeppelin to ensure security and gas efficiency from day one.

We deliver contracts that are secure by design, not as an afterthought.

Our development process includes:

  • Formal Specification & Architecture: Mapping business logic to secure, modular contract structures.
  • Gas-Optimized Coding: Minimizing on-chain execution costs for end-users.
  • Comprehensive Testing: Unit, integration, and fork testing on networks like Sepolia and Mainnet forks.
  • Third-Party Audit Preparation: Code structured and documented for seamless review by leading security firms.

Typical deliverables include custom ERC-20/721/1155 tokens, staking & vesting contracts, multi-signature wallets, and complex DeFi primitives like AMMs or lending pools. We ensure your contracts are upgradeable where needed and include emergency pause functionality.
