CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From token standards to complex DeFi logic, we deliver contracts you can trust to handle real value.
Our typical deliverables include:
- Token Contracts: Custom
ERC-20,ERC-721, andERC-1155implementations with tailored minting, burning, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing systems.
- Utility & Governance: Access control, multi-signature wallets, DAO frameworks, and upgradeable proxy patterns.
- Full Audit Trail: Complete documentation, deployment scripts, and verification on Etherscan or equivalent explorers.
We move from concept to mainnet in 2-4 weeks for an MVP, providing a clear development roadmap, gas usage reports, and post-deployment support. Partner with us to build the secure, scalable smart contract infrastructure your project requires.

END-TO-END SECURITY FRAMEWORK
Core Components of Our Compliance Integration
Our modular compliance stack is engineered for Account Abstraction (ERC-4337) wallets, providing the auditability and control required for regulated FinTechs and Web3 enterprises to scale with confidence.
01
On-Chain Transaction Monitoring
Real-time screening of wallet interactions against OFAC, AML, and proprietary risk databases. Flags high-risk DeFi protocols, mixer interactions, and sanctioned addresses before execution.
< 100ms
Screening Latency
99.9%
Detection Accuracy
02
Modular Policy Engine
Define and enforce granular compliance rules (allow/deny lists, transaction limits, geographic restrictions) at the smart account level. Rules are executed as part of the UserOperation validation flow.

Frequently Asked Questions on AA Compliance
Get clear answers on our process, security, and delivery for compliant Account Abstraction wallet development.
For a standard ERC-4337-compliant wallet with core features (social recovery, batched transactions, paymaster integration), deployment takes 2-4 weeks from kickoff to mainnet. Complex requirements like custom signature schemes or multi-chain deployments may extend this to 6-8 weeks. We provide a detailed project plan with milestones during discovery.
