Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts for tokens, DeFi protocols, and NFT ecosystems. Our development process ensures security-first design and gas optimization from day one.
Deploy with confidence using battle-tested patterns from OpenZeppelin and rigorous internal audits.
Our development stack:
Deliverables you receive:
Our Account Abstraction infrastructure embeds compliance directly into the wallet layer, enabling automated, programmable policy enforcement without sacrificing user experience or developer flexibility.
Plug-and-play compliance logic for jurisdiction-specific requirements. Our audited modules handle Travel Rule data (FATF 16), source-of-funds verification, and real-time sanction screening via Chainalysis or Elliptic integration.
Continuous, automated surveillance of all smart account activity. Generate audit trails for regulators, flag anomalous behavior with ML models, and produce standardized reports for FINRA, SEC, and other authorities.
Sponsor transaction fees for compliant actions. Pay for user gas when they complete KYC or adhere to policies, removing cost barriers while incentivizing regulatory adherence. Full cost transparency and billing.
Enforce consistent compliance rules across Ethereum, Polygon, Arbitrum, and other EVM chains from a single dashboard. Unified policy management prevents regulatory arbitrage and simplifies oversight.
Integrate robust, automated compliance directly into your prediction market's user onboarding and transaction flows. Our Account Abstraction solutions deliver measurable operational and security improvements.
Seamlessly embed identity verification and sanctions screening into smart account creation. Reduce manual review by 80% and onboard institutional users in under 5 minutes.
Programmable security policies at the account level automatically flag and block high-risk prediction market trades based on wallet history, amount, and jurisdiction.
Sponsor gas fees for users while enforcing AML rules on every sponsored transaction. Eliminate user friction without compromising on regulatory requirements.
Every compliance action—from KYC approval to transaction block—is immutably logged on-chain. Generate regulator-ready audit trails in minutes, not days.
Tailor AML rulesets (geofencing, volume caps, counterparty limits) per user segment or market. Update policies via secure multi-sig without contract redeployment.

A structured, four-phase approach designed for institutional clients. We deliver compliant, production-ready Account Abstraction infrastructure with clear milestones, security-first development, and guaranteed SLAs.
We conduct a technical deep-dive to define your AML/KYC policy logic, user flow requirements, and integration points with existing systems. Deliverables include a detailed technical specification and a fixed-price, fixed-scope proposal.
Our engineers architect and develop custom ERC-4337 Bundlers, Paymasters, and Account Factories with embedded compliance logic. All code follows OpenZeppelin standards and is written in Solidity 0.8+ with comprehensive unit testing.
Your smart contracts undergo a rigorous security review by our in-house auditors, followed by deployment to a dedicated testnet environment (Sepolia, Holesky). We provide a full audit report and facilitate UAT with your compliance team.
We manage the mainnet deployment with zero-downtime migration strategies and provide 24/7 monitoring, incident response, and performance optimization. Backed by a 99.9% uptime SLA for Bundler and Paymaster services.
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for tokens, DeFi protocols, and NFTs. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and formal verification tools to mitigate risk.
ERC-20, ERC-721, ERC-1155, and custom implementations.We deliver audited, production-ready contracts in 2-4 weeks, enabling you to launch faster with enterprise-grade security.
Technical questions we commonly receive from CTOs and engineering leads evaluating institutional-grade Account Abstraction solutions.
A standard deployment for a custom ERC-4337 smart account with our modular AML policy engine takes 3-5 weeks from kickoff to mainnet. This includes 1 week for requirements & design, 2-3 weeks for core development and integration, and 1 week for security review and deployment. Complex multi-chain deployments or novel policy logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
