CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts on EVM and Solana that are audit-ready from day one. Our development process integrates formal verification and comprehensive testing to ensure security and reliability for your core protocol logic.

  • Token Systems: ERC-20, ERC-721, ERC-1155, and custom tokenomics with vesting and distribution modules.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking, and yield aggregators.
  • Enterprise Logic: Multi-signature wallets, DAO governance, and custom business logic for real-world assets (RWA).

We deliver a fully documented codebase with a 2-week MVP timeline for standard contracts, backed by our team's experience deploying over 50+ contracts in production.

Frequently Asked Questions

Get clear answers on how our sanctions oracle aggregator service works, from integration to compliance.

Our service aggregates and normalizes data from multiple leading sanctions and watchlist providers (e.g., OFAC, EU, UN, local lists) into a single, high-availability API. We implement a configurable consensus model, where you can define rules (e.g., 2-of-3 providers must flag an address) to trigger alerts or block transactions, ensuring robust and customizable compliance logic.
