We architect and deploy audit-ready smart contracts that power your core business logic. Our development process ensures security-first design, gas optimization, and compliance with key standards like ERC-20, ERC-721, and ERC-1155.
Cross-Chain Payment Gateway Integration
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From specification and
Solidity/Rustcoding to testing and mainnet deployment. - Security Rigor: Built with
OpenZeppelinlibraries and subjected to internal review before third-party audits. - Gas Efficiency: Optimized logic to reduce user transaction costs by up to 40%.
- Upgradeability: Implement secure proxy patterns (
TransparentProxy,UUPS) for future-proofing.
We deliver contracts you can trust, reducing time-to-audit and mitigating critical vulnerabilities before launch.
Partner with us for custom DeFi primitives, NFT collections, DAO governance modules, or enterprise tokenization. Get a production-ready MVP in as little as 3 weeks.
Core Gateway Capabilities
Our cross-chain payment gateway is built on battle-tested infrastructure, delivering the reliability, security, and performance required for high-volume financial applications.
Multi-Protocol Bridge Aggregation
Integrate a single API endpoint that intelligently routes transactions across leading bridges (LayerZero, Axelar, Wormhole) for optimal cost and speed. We manage the complexity of liquidity fragmentation and slippage.
Real-Time Gas Optimization
Automated fee estimation and dynamic gas pricing across EVM and non-EVM chains. Our system predicts network congestion to minimize costs and prevent failed transactions.
Enterprise Security & Compliance
SOC 2 Type II compliant infrastructure with multi-sig transaction signing, real-time threat monitoring, and automated AML screening. All smart contracts are audited by Halborn.
Unified Settlement & Reporting
Consolidated settlement layer with unified transaction IDs, real-time balance tracking, and automated reconciliation. Export compliant reports for accounting and audit trails.
Business Outcomes for Your Platform
Our cross-chain payment gateway is engineered to deliver measurable improvements to your core business metrics, from revenue growth to operational efficiency.
Global Revenue Expansion
Unlock new markets by accepting payments in 50+ native cryptocurrencies across 15+ blockchains. Serve customers where they are, without forcing them to bridge assets.
Reduced Transaction Costs
Intelligent routing finds the most cost-effective path for each transaction, leveraging Layer 2s and optimized bridges to slash gas fees by up to 80% compared to direct on-chain swaps.
Enhanced User Experience
One-click, non-custodial payments with near-instant finality. Users pay with their preferred asset; you receive settlement in your chosen currency, abstracting away blockchain complexity.
Enterprise-Grade Reliability
Built with multi-chain redundancy and 24/7 monitoring. Our gateway ensures 99.9% uptime SLA, protecting your revenue stream from single-chain outages or congestion.
Faster Time-to-Market
Integrate a production-ready gateway in weeks, not months. Our modular APIs and comprehensive SDKs handle cross-chain logic, so your team can focus on core product features.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for integrating a secure, scalable cross-chain payment gateway.
A standard cross-chain payment gateway integration takes 4-6 weeks from kickoff to mainnet deployment. This includes smart contract development, bridge integration, frontend/API development, security audits, and testing on testnets. More complex requirements, like supporting 10+ chains or custom settlement logic, can extend the timeline to 8-10 weeks. We provide a detailed project plan with weekly milestones.
