We architect and deploy audit-ready smart contracts that form the foundation of your dApp. Our development process is built on security-first principles using Solidity 0.8+ and OpenZeppelin libraries, ensuring your core logic is robust and upgradeable.
Real-Time Payment Routing Sub-Account Infrastructure
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
- Custom Logic: From
ERC-20tokens andERC-721NFTs to complex DeFi vaults and governance systems. - Gas Optimization: We write efficient code to reduce user transaction costs by up to 40%.
- Full Testing Suite: Comprehensive unit and integration tests with >95% coverage before audit.
- Deployment & Verification: Automated deployment scripts and immediate source code verification on Etherscan and other explorers.
We deliver a complete, documented codebase in 2-4 weeks, ready for external audit and mainnet launch.
Core Capabilities of Our Routing Infrastructure
Our sub-account routing infrastructure is engineered for fintechs and Web3 companies requiring high-volume, low-latency payment orchestration. We deliver the reliability and programmability you need to scale.
Real-Time Payment Orchestration
Dynamically route transactions across multiple liquidity sources (CEXs, DEXs, on/off-ramps) based on live price, latency, and cost. Achieve optimal execution for every user payment, reducing slippage and failed transactions.
Multi-Chain Sub-Account Management
Deploy and manage thousands of isolated, non-custodial sub-accounts programmatically. Each account operates on EVM-compatible chains (Ethereum, Polygon, Arbitrum) with granular permissions and automated fund sweeping.
Gas Optimization Engine
Intelligent gas fee management with multi-layer strategies: EIP-1559 estimation, private mempool routing, and batch transaction bundling. Drastically reduce operational costs for high-frequency payment flows.
Security & Compliance Layer
Built with institutional security standards. Features include MPC-based key management, real-time AML/sanctions screening via integrated providers, and comprehensive audit trails for every routed transaction.
Developer-First API
RESTful and WebSocket APIs for seamless integration. Complete with SDKs, webhook alerts for settlement events, and a sandbox environment for testing complex routing logic before going live.
Analytics & Settlement Reporting
Real-time dashboards and automated reports for transaction success rates, cost analysis per route, and sub-account activity. Export data for reconciliation and financial reporting.
Business Outcomes: Beyond Technical Execution
Our Real-Time Payment Routing Sub-Account Infrastructure delivers more than code. It's a strategic asset that drives measurable business growth, operational efficiency, and competitive advantage for FinTechs and Web3 platforms.
Accelerate Time-to-Revenue
Launch new payment products in under 4 weeks with our pre-audited, modular infrastructure. We handle the complex routing logic and compliance, so you can focus on customer acquisition and go-to-market strategy.
Reduce Operational Overhead by 70%
Eliminate the need for in-house teams to build and maintain complex payment rails. Our managed infrastructure with 24/7 monitoring and automatic upgrades cuts operational costs and frees your engineers for core product work.
Guaranteed Transaction Finality & Uptime
Build trust with enterprise clients using our 99.95% SLA for infrastructure uptime and sub-second payment finality across integrated chains (Ethereum, Polygon, Arbitrum). No failed settlements, no reconciliation headaches.
Seamless Multi-Chain & Fiat Expansion
Future-proof your platform. Our architecture allows you to add new blockchain networks (Solana, Base) and fiat on/off-ramp partners (Stripe, Circle) in days, not months, capturing new markets as they emerge.
Real-Time Analytics & Treasury Visibility
Gain instant insights into cash flow, sub-account balances, and routing performance. Our dashboard provides the data you need for treasury management, financial reporting, and optimizing payment flows.

Our Delivery Methodology: From Architecture to Go-Live
A structured, milestone-driven approach to deliver production-ready payment infrastructure. We manage the entire lifecycle, ensuring technical excellence and predictable timelines.
Architecture & Design Sprint
We conduct a 2-week collaborative sprint to define your multi-chain routing logic, sub-account structure, and security model. Deliverables include a technical specification and a detailed architecture diagram.
Smart Contract Development & Auditing
Our engineers build modular, gas-optimized smart contracts for account abstraction and payment routing. All code undergoes internal review and is prepared for a formal security audit by firms like Quantstamp or CertiK.
Relayer & Indexer Integration
We deploy and configure the off-chain infrastructure: high-availability transaction relayers for gas sponsorship and real-time indexers for sub-account balance tracking and event monitoring.
Staging Environment Deployment
Your complete infrastructure is deployed to a private staging environment on testnets (Sepolia, Holesky). We execute comprehensive integration tests, load testing, and provide full documentation for your team.
Security Audit & Penetration Testing
We facilitate and manage the engagement with a top-tier audit firm. We address all findings, provide a detailed remediation report, and conduct internal penetration testing on the deployed infrastructure.
Production Go-Live & Monitoring
We manage the mainnet deployment, configure monitoring dashboards (Grafana), alerting (PagerDuty), and provide 24/7 incident response support for the first 30 days post-launch.
Frequently Asked Questions
Get specific answers about our sub-account infrastructure for instant, multi-chain settlements.
A standard deployment for a multi-chain payment router with 5-10 supported assets takes 3-4 weeks. This includes smart contract development, integration with our sub-account API, and end-to-end testing. For more complex requirements like cross-chain atomic swaps or integration with proprietary ledgers, timelines extend to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
