We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our engineers write in Solidity 0.8+ and Rust, leveraging battle-tested patterns from OpenZeppelin and Solmate. Deliverables include a comprehensive audit report and gas-optimized code ready for mainnet.
Regulatory-Compliant Relayer Setup
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Formal verification, fuzz testing, and peer review to eliminate vulnerabilities.
- Full-Stack Integration: Contracts are delivered with TypeScript SDKs and subgraph schemas for seamless frontend integration.
- Proven Track Record: We've deployed over 200 contracts with $0 lost to exploits across client projects.
Core Components of a Compliant Relayer
A compliant relayer is more than a transaction router; it's a secure, auditable system designed for regulated markets. Our setup delivers enterprise-grade components that ensure legal adherence without sacrificing performance.
Transaction Sanction Screening
Real-time screening of all transaction participants (senders, recipients, smart contracts) against global sanctions lists (OFAC, EU) before broadcast. Prevents regulatory violations at the network edge.
Compliant Gas Abstraction
Gas sponsorship logic that enforces KYC/AML checks before subsidizing user fees. Configurable rulesets ensure only verified users benefit, maintaining audit trails for all sponsored transactions.
Immutable Audit Logging
Every relayed transaction, screening result, and policy decision is immutably logged to a private, encrypted ledger. Provides a tamper-proof record for internal audits and regulatory reporting.
Jurisdictional Policy Engine
Dynamic rule engine that applies transaction filters based on user geography, asset type, and transaction value. Enables automatic compliance with region-specific regulations like MiCA or local VASP laws.
Secure Key Management
HSM-backed or MPC (Multi-Party Computation) vaults for relayer operator keys. Eliminates single points of failure and ensures private keys never exist in plaintext on a server, meeting institutional security demands.
Real-Time Monitoring & Alerts
Dashboard and API for monitoring transaction flow, compliance hit rates, and system health. Configurable alerts for suspicious patterns, failed screenings, or SLA breaches enable proactive governance.
Business Outcomes: Security, Speed, and Auditability
Our regulatory-compliant relayer setup delivers measurable results for FinTechs and crypto-native businesses. We build on-chain infrastructure that meets strict compliance requirements without sacrificing performance.
Bank-Grade Security & Compliance
Deploy relayers with built-in AML/KYC transaction screening, OFAC sanction checks, and geofencing. Our infrastructure is built on battle-tested frameworks like OpenZeppelin Defender and undergoes regular third-party security audits.
Sub-Second Transaction Finality
Achieve high-throughput transaction processing with optimized gas strategies and multi-chain routing. Our relayers are engineered for low-latency execution, critical for DeFi arbitrage and real-time settlement.
Full Transaction Audit Trail
Every relayed transaction is immutably logged with sender identity, compliance checks passed, and gas costs. Generate regulatory reports on-demand for internal audits or external authorities.
Reduced Operational Overhead
Eliminate the engineering burden of maintaining compliant infrastructure. We handle node health, security patches, compliance rule updates, and multi-chain support, letting your team focus on core product development.
Build vs. Buy: The Compliance Relayer Decision
A detailed comparison of the time, cost, and risk involved in developing a compliant relayer in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore Managed Service |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Burden | High (Your Responsibility) | Low (Pre-Audited Templates) |
Compliance Rule Engine | Custom Build Required | Pre-built for AML/KYC |
Multi-Chain Support | Per-Chain Integration | Native (EVM, Solana, etc.) |
Uptime & Monitoring SLA | You Build & Maintain | 99.9% Guaranteed |
Team Requirements | 3-5 Senior Engineers | Your Integration Lead |
Ongoing Maintenance Cost | $150K+ / year | Optional SLA from $30K/year |
Regulatory Updates | Manual Tracking & Patching | Automated Policy Updates |
Our Delivery Process: From Audit to Production SLA
We deliver a fully managed, compliant relayer infrastructure with a clear, predictable path to production. Our process is built on security-first principles and guaranteed performance.
Compliance & Architecture Review
We analyze your target jurisdictions (e.g., MiCA, FinCEN) and design a system architecture that embeds compliance controls from day one. This includes transaction screening, KYC/AML integration points, and data retention policies.
Relayer Node Deployment
We provision, configure, and deploy high-availability relayer nodes on your chosen cloud infrastructure (AWS/GCP). Configuration includes private transaction mempools, gas optimization, and real-time monitoring dashboards.
Compliance Middleware Integration
We integrate enterprise-grade compliance tools (Chainalysis, Elliptic) directly into your transaction flow. This enables real-time sanction screening and automated reporting for regulatory adherence.
Staging & Load Testing
Before go-live, we simulate production load—testing for thousands of TPS under peak conditions. We validate system stability, fee accuracy, and compliance rule execution to prevent surprises.
Production SLA & Ongoing Management
Go live with a guaranteed 99.95% uptime SLA, 24/7 incident response, and proactive health monitoring. We manage node upgrades, security patches, and compliance rule updates as regulations evolve.
Compliance Relayer FAQs
Answers to common questions from CTOs and technical founders evaluating a regulatory-compliant relayer solution.
Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes configuration for KYC/KYB checks, transaction monitoring, and integration with your dApp frontend. Complex multi-chain setups or custom compliance rule engines may extend to 6-8 weeks. We provide a detailed project plan within the first 3 business days.
