Regulatory-Compliant Relayer Setup

Deploy a secure, gasless transaction relayer with embedded KYC/AML verification, real-time monitoring, and audit trails to meet institutional and jurisdictional requirements.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

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.

  • 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.

ARCHITECTURE

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.

01

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.

Screening Latency
99.99%
List Accuracy
02

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.

Compliance Record
03

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.

04

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.
