CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for speed, scalability, and compliance.
We architect and deploy custom Solidity/Rust smart contracts that form the immutable business logic of your application. Our focus is on security-first development, leveraging audited libraries like OpenZeppelin and implementing formal verification where required.
Deliver a secure, audited MVP in as little as 2-3 weeks, with a clear path to mainnet deployment.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults with advanced features like minting schedules and governance hooks. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking contracts, and yield optimizers.
- Enterprise Logic: Multi-signature wallets, vesting schedules, and compliant KYC/AML integration modules.
- Post-Deployment: Comprehensive audit support, upgradeability patterns (
Transparent/UUPS), and monitoring setup.

Frequently Asked Questions
Get clear answers about our development process, security, and timelines for custom ZK-Rollup state transition services.
We follow a structured 4-phase delivery model. Discovery & Design (1-2 weeks) defines requirements and architecture. Core Development (3-5 weeks) builds the state transition logic, prover/verifier circuits, and integration layer. Testing & Audit (2-3 weeks) includes internal testing, formal verification of circuits, and a third-party audit. Deployment & Handoff (1 week) finalizes mainnet deployment and documentation. A typical end-to-end project takes 7-11 weeks, depending on custom logic complexity and the chosen proving system (e.g., Plonk, STARKs).
