CORE SERVICES

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We deliver custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process ensures security-first architecture, gas optimization, and full audit readiness from day one.

Deploy with confidence using battle-tested patterns from OpenZeppelin and rigorous internal testing.

  • Protocols: ERC-20, ERC-721, ERC-1155, ERC-4626, and custom standards.
  • Stack: Solidity 0.8+, Hardhat, Foundry, with comprehensive test suites.
  • Delivery: Full source code, deployment scripts, and technical documentation.

Our engineers specialize in complex logic like multi-signature wallets, vesting schedules, upgradeable proxies, and cross-chain interoperability. We focus on mainnet readiness to eliminate costly post-launch fixes.

Core Technical Capabilities We Deliver

We build production-ready, privacy-first mobile wallets with battle-tested ZK-Rollup infrastructure. Our focus is on delivering secure, scalable, and user-friendly applications that go live faster.

01

Custom ZK-Rollup Integration

We implement StarkEx or zkSync Era rollups to enable private, low-cost transactions. Our integration handles proof generation, state management, and L1/L2 bridging, reducing your gas fees by up to 100x.
