We provide dedicated, non-shared RPC endpoints with 99.9% SLA uptime and sub-second latency. Our infrastructure is built for production workloads, eliminating the operational overhead of self-hosting.
Account Abstraction Compliance Overlay
Blockchain Node Infrastructure
Fully managed, high-performance nodes for Ethereum, Solana, and other leading protocols.
- Multi-Protocol Support: Full nodes & archival access for
EVMchains (Ethereum, Polygon, Arbitrum),Solana,Cosmos, and more. - Enterprise Security: Isolated environments, DDoS protection, and role-based access control (RBAC).
- Developer Experience: Real-time metrics, WebSocket support, and automatic failover for zero-downtime deployments.
Focus on building your application, not maintaining infrastructure. We handle node synchronization, upgrades, and scaling so your team doesn't have to.
Core Capabilities of Our Compliance Overlay
Our modular compliance overlay integrates directly with your AA stack, enabling rapid deployment of institutional-grade controls without sacrificing user experience or developer velocity.
Real-Time Transaction Screening
Automatically screen every user operation against global sanctions lists (OFAC, UN) and proprietary risk databases before on-chain execution. Prevents non-compliant interactions at the protocol level.
Modular Policy Engine
Deploy and manage granular compliance rules (geofencing, velocity limits, counterparty restrictions) via a no-code dashboard or API. Policies are enforced by smart contract verifiers before transaction finality.
Non-Custodial KYC/AML Attestations
Integrate with leading identity providers (Persona, Onfido) to bind verified credentials to AA wallets. Store attestations off-chain with privacy-preserving ZK proofs for on-chain verification.
Audit Trail & Reporting
Generate immutable, tamper-proof logs of all screened transactions, policy decisions, and user attestations. Automate reporting for regulators (FATF Travel Rule, MiCA) with customizable exports.
Gas Abstraction for Compliance
Sponsor gas fees for mandatory compliance checks, ensuring a seamless user experience. Our paymaster contracts batch and optimize verification transactions to reduce operational costs by up to 40%.
Business Outcomes: Reduce Risk, Accelerate Growth
Our Account Abstraction Compliance Overlay is engineered to deliver measurable business impact, turning regulatory complexity into a competitive advantage for your Web3 application.
Eliminate Compliance Risk
Automated, on-chain enforcement of KYC/AML and sanctions screening for every user session and transaction. Mitigate regulatory exposure and protect your business from costly fines and operational shutdowns.
Accelerate Time-to-Market
Deploy a production-ready compliance layer in days, not months. Our pre-built, audited modules integrate seamlessly with ERC-4337 and ERC-6900 standards, eliminating the need for in-house legal and engineering overhead.
Unlock Global User Onboarding
Enable compliant user acquisition across 150+ jurisdictions with dynamic, jurisdiction-aware rule sets. Automatically adapt verification flows and transaction limits based on user geography and risk profile.
Reduce Operational Costs
Replace manual review processes and fragmented third-party services with a unified, automated compliance stack. Achieve significant savings on legal counsel, compliance officer hours, and vendor management.
Enhance Developer Experience
Simple SDKs and well-documented APIs allow your engineering team to focus on core product features. Comprehensive logs and dashboards provide full visibility into compliance status without slowing down development.
Future-Proof Your Stack
Our overlay is built to adapt to evolving global regulations. We maintain and update the compliance logic, ensuring your application remains compliant without requiring constant, costly re-engineering.
Build vs. Buy: Compliance Enforcement Options

Our Delivery Process: From Audit to Integration
A structured, transparent workflow designed for technical leaders. We deliver a production-ready Account Abstraction compliance overlay with clear milestones, from initial security review to final API integration.
1. Architecture & Compliance Audit
We conduct a deep technical review of your existing smart account architecture (ERC-4337, Safe{Core}) and transaction flows. We identify compliance gaps and map requirements to specific AA features like session keys and batched operations.
2. Smart Contract Development & Hardening
Our engineers build and extend your Paymaster, Account Factory, and custom modules using Solidity 0.8+ and OpenZeppelin libraries. Every line is written with gas optimization and upgradeability (via proxies) in mind.
4. Testnet Deployment & Simulation
We deploy the full stack to Sepolia or Goerli testnets. We run exhaustive simulation tests using Tenderly and custom scripts to validate compliance rules under edge-case transaction loads.
5. Mainnet Launch & Monitoring
Managed deployment to Ethereum Mainnet or your target L2 (Arbitrum, Optimism, Base). We configure real-time monitoring with alerts for failed user operations and compliance rule triggers.
Frequently Asked Questions
Common questions from CTOs and compliance leads implementing AA for regulated applications.
From kickoff to mainnet deployment, a standard implementation takes 3-5 weeks. This includes a 1-week discovery and design phase, 2-3 weeks of core development and integration, and a final week for security review and deployment. Complex multi-chain or heavily regulated use cases (e.g., MiCA-ready wallets) may extend to 8 weeks.
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
We architect and deploy custom Solidity/Rust smart contracts with enterprise-grade security and gas optimization as first principles. Every contract undergoes a rigorous audit process, including automated analysis, manual review, and formal verification where required.
- Token Systems: Custom
ERC-20,ERC-721,ERC-1155with advanced features like vesting, bonding curves, and multi-chain bridging. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and staking mechanisms.
- Governance & DAOs: Modular voting systems, treasury management, and permissioned access controls.
- Utility Contracts: Oracles integration, random number generation, and upgradeable proxy patterns for future-proofing.
We deliver audit-ready code in 2-4 weeks, reducing your time-to-market and technical risk. Our contracts are built on battle-tested libraries like
OpenZeppelinand follow industry best practices for security and maintainability.
