Deploy a battle-tested, auditable smart contract foundation in as little as 2-4 weeks, reducing your technical risk and accelerating time-to-market.
Core Architecture Components We Deliver
We build the critical infrastructure that bridges traditional finance and blockchain, ensuring compliance, speed, and reliability for your payment rails.
Compliance-First Gateway API
A unified API layer handling KYC/AML, transaction monitoring, and jurisdictional rule-sets. Integrates with leading providers like Sumsub and Jumio to automate onboarding and ensure regulatory adherence.
Multi-Chain Settlement Engine
Smart contract system for atomic settlement across EVM and non-EVM chains. Features automated gas management, multi-sig controls, and real-time status tracking to eliminate settlement risk.
Fiat Liquidity Orchestrator
Intelligent routing layer that connects to multiple banking partners and payment processors (Plaid, Stripe) to optimize for cost, speed, and availability, ensuring seamless on/off-ramp flows.
Real-Time Risk & Fraud Module
Proprietary monitoring system that analyzes transaction patterns, IP addresses, and wallet behavior in real-time to flag and block fraudulent activity before settlement.
Unified Dashboard & Reporting
Admin dashboard providing a single pane of glass for transaction reconciliation, user management, financial reporting, and compliance audits. Exports data for accounting systems.
Modular Smart Contract Suite
Audited, upgradeable smart contracts for custody, escrow, and fee distribution. Built with OpenZeppelin standards and includes emergency pause functions and role-based access control.
Business Outcomes for Your RWA Platform
Our Hybrid On/Off-Ramp Payment Rail Architecture delivers measurable improvements in capital efficiency, compliance, and user experience for tokenizing real-world assets.
Faster Time-to-Market
Deploy a compliant, production-ready payment rail in weeks, not months. We provide pre-integrated modules for KYC/AML, multi-currency settlement, and bank connectivity.
Reduced Transaction Costs
Cut settlement fees by up to 80% versus traditional rails. Our hybrid architecture optimizes for on-chain efficiency and off-chain bulk processing.
Enhanced Regulatory Compliance
Built-in compliance engine supports Travel Rule (FATF 16), jurisdictional AML rules, and real-time sanction screening via integrated provider APIs.
Improved Capital Efficiency
Enable 24/7 instant settlement for secondary RWA trading while maintaining secure, batched reconciliation with traditional banking hours.
Scalable User Onboarding
Seamlessly onboard both crypto-native and traditional investors with flexible fiat entry points (ACH, Wire, Card) and custodial options.
Enterprise-Grade Security & Audit Trail
Every transaction is cryptographically signed and recorded with an immutable audit trail, simplifying reporting for internal and regulatory reviews.
Build vs. Buy: The Hybrid Payment Rail Architecture
A detailed comparison of the time, cost, and risk involved in developing a compliant on/off-ramp system in-house versus partnering with Chainscore Labs.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Launch | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K |
Compliance & Licensing Overhead | High (Your Responsibility) | Pre-integrated (Our Responsibility) |
Security & Audit Burden | High (Unaudited Code Risk) | Low (Pre-audited, Battle-Tested Modules) |
Supported Payment Methods | Manual Integration (Limited) | Pre-built (Cards, ACH, SEPA, PIX, etc.) |
Supported Blockchains | Requires Custom RPC & Indexer Dev | Pre-integrated (EVM, Solana, Cosmos, etc.) |
Ongoing Maintenance & Updates | Dedicated 3-5 Person Team | Fully Managed Service (Optional SLA) |
Fraud & AML Monitoring | Build from Scratch | Pre-configured Rules Engine |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $80K - $200K |
Strategic Outcome | Diverts focus from core product | Accelerates GTM and user acquisition |
Our Phased Delivery Methodology
We de-risk your payment rail integration with a structured, milestone-driven approach that ensures alignment, security, and rapid time-to-market.
Phase 1: Discovery & Architecture
We conduct a technical deep-dive to map your existing systems, define tokenization strategy (ERC-20, ERC-1155), and design a secure, scalable architecture blueprint.
Phase 2: Core Rail Development
Our engineers build the core on/off-ramp smart contracts (Solidity 0.8+) and backend APIs, implementing KYC/AML flows, liquidity pools, and settlement logic.
Phase 3: Security & Integration
All smart contracts undergo a formal audit (e.g., by Halborn or CertiK). We then integrate the rail with your frontend and backend systems in a staging environment.
Phase 4: Launch & Scale
We manage the production deployment, configure monitoring (uptime, fraud detection), and provide documentation and training for your team to operate the system.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our focus is on security-first development, using audited patterns from OpenZeppelin and rigorous internal testing to mitigate vulnerabilities before deployment.
From tokenization to complex DeFi protocols, we deliver contracts that are gas-optimized, upgradeable, and built for your specific regulatory environment.
- Token Standards: Full
ERC-20,ERC-721,ERC-1155, andSPLimplementation with custom minting, vesting, and transfer logic. - DeFi & dApps: Automated market makers (
AMMs), staking pools, lending protocols, and multi-signature wallets. - Security & Compliance: Pre-deployment audits, formal verification where applicable, and integration with monitoring tools like
Forta. - Delivery: Production-ready code in 2-4 weeks, complete with documentation and deployment scripts.
Frequently Asked Questions
Get specific answers about our payment rail development process, timelines, security, and support.
A complete, production-ready hybrid on/off-ramp system typically deploys in 4-8 weeks. This includes the smart contract suite, fiat gateway integrations (like Stripe, Plaid), KYC/AML orchestration layer, and the reconciliation engine. The timeline varies based on the number of target payment methods (bank transfers, cards, local methods) and blockchain networks (EVM, Solana, etc.). We provide a detailed project plan within the first week of engagement.
