CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and tax logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and compliant asset tokenization.
- Full Audit Trail: Every contract includes comprehensive documentation and a verifiable audit report from partners like CertiK or Halborn.
We deliver battle-tested code that executes as intended, reducing post-launch vulnerabilities and protecting your users' assets.
Our engagement model is designed for speed: deploy a production-ready MVP in 2-4 weeks. We provide ongoing support for upgrades and maintenance, ensuring your contracts evolve with your protocol.

PROACTIVE SECURITY LAYER
Core Monitoring Capabilities
Our fraud proof monitor acts as a dedicated security layer for your optimistic rollup, providing continuous, automated verification to protect user funds and ensure network integrity.
01
Real-Time State Verification
Continuously monitors the L2 state root posted to the L1, automatically initiating a fraud proof challenge within the dispute window if an invalid state is detected. This prevents incorrect withdrawals and protects user assets.

02
Automated Challenge Submission
Our system autonomously constructs and submits the cryptographic fraud proof to the L1 verifier contract, handling all gas optimization and transaction management. Eliminates manual intervention and human error.
