We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, leveraging battle-tested libraries like OpenZeppelin and following formal verification patterns to mitigate risks before the first line of code is written.
Compliance-Focused Attestation Engine
Smart Contract Development
Secure, production-ready smart contracts built by certified auditors.
Deliver a secure, audited, and gas-optimized contract suite in as little as 2-4 weeks.
Our full-service development includes:
- End-to-end lifecycle management: From initial design and
Solidity 0.8+development to deployment onEVM/L2chains and post-launch maintenance. - Integrated security audits: Every contract undergoes internal review by certified auditors before we recommend third-party verification, significantly reducing critical vulnerabilities.
- Gas optimization: We implement patterns to reduce user transaction costs by 20-40% on average, a critical factor for adoption.
- Comprehensive testing: Full test suites with >95% coverage using
HardhatorFoundry, including simulations of mainnet conditions and edge cases.
Core Capabilities for Compliance Officers and Engineers
Our attestation engine provides the technical depth engineers demand and the operational clarity compliance teams require. We deliver verifiable, on-chain proof of regulatory adherence.
Automated Policy Enforcement
Programmable compliance rules deployed as on-chain smart contracts. Automatically validate transactions against OFAC lists, jurisdictional restrictions, and internal risk policies in real-time.
Tamper-Proof Audit Trail
Every compliance decision and user attestation is immutably recorded on-chain. Provides a single source of truth for internal audits and regulator inquiries, eliminating data reconciliation.
Modular Rule Engine
Drag-and-drop interface for compliance officers to build logic, with Solidity code generation for engineers. Supports complex, multi-chain rules without requiring smart contract redeployment.
Real-Time Risk Scoring
Dynamic, on-chain scoring of wallet addresses and transactions based on provenance, behavior, and linked identities. Enables tiered compliance measures from enhanced due diligence to automatic blocks.
Cross-Chain Attestation Portability
User compliance status and KYC/AML attestations are portable across EVM and non-EVM chains via our verifiable credential standard. Avoid re-screening users for each new protocol.
Regulator-Friendly Reporting
Generate standardized compliance reports (e.g., Travel Rule, SAR) with cryptographic proof of data integrity. One-click export for designated examiners with read-only access portals.
Business Outcomes: De-Risk and Scale
Our attestation engine is engineered for enterprise-grade reliability, providing the security and scalability needed to operate with confidence in regulated markets.
Audit-Ready Compliance
Generate immutable, on-chain proof of your compliance posture for regulators and auditors. Every transaction and rule enforcement is cryptographically verifiable, slashing audit preparation time and cost.
Real-Time Risk Mitigation
Prevent non-compliant transactions before they reach the blockchain. Our engine enforces AML, KYC, and sanctions policies at the protocol layer, eliminating costly remediation and regulatory fines.
Infinite Scalability
Architected for high-throughput DeFi and institutional volumes. Horizontally scalable attestation nodes ensure sub-second finality and 99.9% uptime, even during market volatility.
Reduced Integration Friction
Deploy a compliant Web3 product in weeks, not months. Our modular APIs and SDKs plug directly into your existing wallet, exchange, or custody stack with minimal engineering lift.
Future-Proof Policy Management
Adapt to evolving global regulations without code changes. Our no-code policy dashboard lets compliance teams update rules for AML, travel rule, and jurisdiction instantly.
Institutional-Grade Security
Built on battle-tested cryptographic primitives and audited by leading security firms. Multi-sig key management and zero-trust architecture protect your most sensitive compliance logic.

Designed for High-Stakes Applications
Our attestation engine is built from the ground up for financial institutions, regulated DeFi protocols, and custodians where failure is not an option. We deliver the security, performance, and compliance guarantees required for production at scale.
Institutional-Grade Security
Multi-signature key management, hardware security module (HSM) integration, and SOC 2 Type II compliant infrastructure. Every attestation is cryptographically signed and tamper-evident.
Sub-Second Attestation Latency
Generate and verify on-chain attestations in under 500ms, ensuring real-time compliance checks for high-frequency trading, payments, and on-chain settlements without bottlenecks.
Regulatory-First Architecture
Pre-configured templates for FATF Travel Rule, MiCA, and OFAC sanctions screening. Built-in audit trails and immutable logs simplify reporting for financial regulators.
99.99% Uptime SLA
Guaranteed availability with geo-redundant, multi-cloud deployment. Automated failover and 24/7 monitoring ensure your compliance operations never go offline.
Smart Contract Development
Secure, production-ready smart contracts built by experts to power your Web3 application.
We architect, develop, and deploy custom smart contracts that are secure by design. Our process includes threat modeling, formal verification with tools like Slither and MythX, and comprehensive unit/integration testing to ensure robustness and reliability before mainnet deployment.

Frequently Asked Questions for Technical Leaders
Technical questions from CTOs and engineering leads evaluating our attestation infrastructure for regulated applications.
Standard deployment for a production-ready attestation engine with core compliance modules (KYC/AML, transaction monitoring) takes 2-4 weeks. Complex integrations with existing legacy systems or custom regulatory rule-sets can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during the initial technical scoping call.
