Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process is built on audited security patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.
Deliver a secure, audited MVP in as little as 2-4 weeks.
Our development stack includes:
We ensure your contracts are built for the real world:
Our sanctions module development is built on a foundation of audited security, protocol-native integration, and measurable performance. We deliver production-ready code that meets regulatory requirements without compromising on-chain efficiency.
Seamlessly embed sanctions logic directly into your smart contracts or off-chain indexers. We build for EVM chains (Ethereum, Polygon, Arbitrum) and Solana, ensuring compatibility with your existing token standards and governance models.
Every module undergoes rigorous security review. We implement OpenZeppelin patterns, conduct internal audits, and prepare your code for third-party verification by firms like CertiK or Trail of Bits to mitigate financial and reputational risk.
Integrate with real-time data feeds from providers like Chainalysis or TRM Labs. We build automated update mechanisms with multi-signature controls, ensuring your sanctions list is current and tamper-evident.
Engineered for minimal on-chain footprint. Our modules use efficient data structures and verification patterns to keep gas costs low for end-users, critical for maintaining adoption in DeFi and NFT applications.
Go beyond simple blocklists. Implement complex, programmable logic for jurisdiction-based rules, amount thresholds, and time-based restrictions tailored to your product's specific risk and compliance requirements.
We handle the full deployment lifecycle on testnet and mainnet. Includes comprehensive monitoring dashboards and comes with a 99.9% uptime SLA for the critical verification components of the system.
Our Smart Contract Sanctions Module delivers measurable security and compliance outcomes, enabling you to launch with confidence and scale without regulatory friction.
Integrate real-time OFAC, UN, and EU sanctions list checks directly into your protocol's logic. We deliver a modular, upgradeable system that adapts to evolving global regulations, protecting your business from legal exposure.
Our modules are built with Solidity 0.8+ and OpenZeppelin patterns, featuring Merkle tree proofs and efficient storage to minimize gas costs for compliance checks, ensuring user experience isn't compromised.
Every sanctions module undergoes a rigorous security audit by certified firms like Trail of Bits or ConsenSys Diligence. We deliver a formal verification report and a 12-month warranty on critical logic.
Get from specification to mainnet in under 3 weeks. We provide a complete deployment package with test suites, monitoring dashboards, and integration guides for EVM chains like Ethereum, Polygon, and Arbitrum.
Go beyond basic list checks. We implement complex, programmable compliance rules—like jurisdiction-based restrictions or transaction amount thresholds—tailored to your specific product and risk model.
Receive 24/7 monitoring of your module's performance and health. Our team provides priority support for emergency list updates and protocol upgrades, backed by a clear SLA.
