CORE INFRASTRUCTURE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, yield aggregators.
- Gas Optimization: Achieve up to 40% lower transaction costs through advanced Solidity patterns.
- Full Audit Trail: Complete documentation and a verifiable deployment history on Etherscan.
From a 2-week MVP to a complex multi-chain system, we deliver contracts that are reliable, upgradeable, and ready to scale.

Frequently Asked Questions
Get clear answers on development timelines, security, integration, and support for your custom blockchain sanctions screening solution.
A production-ready sanctions screening engine typically takes 4-8 weeks from kickoff to deployment. The timeline depends on the complexity of your integration (e.g., wallet, exchange, payment rail), the number of blockchains you need to monitor, and the volume of transactions. We deliver a working MVP within 2-3 weeks for initial validation.
