CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Standards: Custom
ERC-20,ERC-721, andERC-1155with minting, vesting, and governance modules. - DeFi & DAOs: Automated Market Makers (AMMs), staking pools, and multi-sig governance contracts.
- Security First: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
Reduce your time-to-audit by 50% with our battle-tested development framework and documentation.
We provide full deployment support on EVM chains (Ethereum, Polygon, Arbitrum) and handle upgradeability via transparent proxies, ensuring your protocol can evolve without compromising user trust.

Frequently Asked Questions
Get specific answers about our specialized service for building real-time, on-chain sanctions screening on Solana.
A Rust-based sanctions screening engine is a custom program (Solana program) that validates transactions against real-time sanctions lists directly on-chain. We build on Solana for its high throughput (65,000+ TPS) and sub-second finality, enabling real-time compliance checks without sacrificing user experience. This is critical for DeFi protocols, payment rails, and exchanges that require instant, automated compliance.
