CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721, andERC-1155implementations with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing modules.
- Enterprise Logic: Multi-signature wallets, access control systems, and compliant asset tokenization frameworks.
Every contract undergoes a rigorous audit cycle, including internal review, automated testing with Hardhat/Foundry, and integration with leading security firms. We deliver fully documented code and deployment scripts for mainnet launch.

TANGIBLE RESULTS
Business Outcomes for Your Lending Platform
Our ZK-Rollup NFT Loan Privacy Layer delivers measurable advantages, from enhanced security to accelerated time-to-market. Here’s what you can expect.
01
Zero-Knowledge Transaction Privacy
We implement zk-SNARKs to shield loan amounts, collateral values, and borrower identities on-chain, enabling confidential lending without compromising auditability.

Technical & Business Comparison
ZK-Rollup Privacy Layer vs. Public Mainnet Lending
A side-by-side analysis of key architectural, operational, and business factors to inform your NFT lending platform's infrastructure strategy.
| Feature | Public Mainnet Lending | ZK-Rollup Privacy Layer |
|---|---|---|
Loan Position Privacy | ||
Transaction Cost per Loan | $5-$50+ | < $0.01 |
Time to Finality | ~5 min (Ethereum) | < 2 seconds |
Development & Audit Timeline | 6-9 months | 8-12 weeks |
Regulatory Data Exposure | Full on-chain history | Selective, verifiable proofs |
Infrastructure Complexity | High (gas management, mempools) | Managed (single settlement layer) |
Typical Implementation Cost | $200K - $500K+ | $75K - $150K |
Competitive Moats | Brand & liquidity only | Brand, liquidity & privacy |

CLIENT-CENTRIC DELIVERY
Our Implementation Process
A structured, transparent approach to deploying your private NFT loan layer. We focus on security, speed, and seamless integration to get you to market faster.
01
Architecture & Design Review
We conduct a deep technical analysis of your existing NFT lending protocol to design a custom ZK-Rollup privacy layer. This includes defining the optimal zero-knowledge proof circuits and data availability strategy for your specific use case.
