overview
RELIABLE FOUNDATION
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.
01
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.

CLIENT-CENTRIC EXECUTION
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.
01
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.

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.
