overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155tokens with tailored minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and custom business logic for real-world asset (RWA) tokenization.
We deliver battle-tested code with a focus on gas efficiency and upgradeability patterns (like Transparent Proxies) to protect your long-term roadmap.
From initial architecture to mainnet deployment, we ensure your contracts are secure by design and ready to handle real economic value. Our typical engagement delivers a production-ready MVP in 3-5 weeks.

Frequently Asked Questions
Get clear answers on how our managed relay service accelerates your ZK-Rollup deployment and operations.
A ZK-Rollup State Transition Relay is a critical off-chain service that submits your rollup's state roots and zero-knowledge proofs to the underlying L1 (like Ethereum). It handles transaction batching, proof generation coordination, and L1 submission with optimal gas efficiency. You need one to ensure your rollup's state is finalized on-chain reliably and cost-effectively, avoiding the operational overhead of managing your own relay infrastructure, which requires deep expertise in gas optimization and L1 congestion handling.
