We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on audited security patterns and gas-optimized code, ensuring your protocol is both secure and cost-effective to operate.
Cross-Chain Payment Gateway Development
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial architecture and
Solidity/Rustcoding to deployment onEVM/Solanaand ongoing maintenance. - Security-First Approach: All contracts undergo rigorous internal audits and are built with
OpenZeppelinstandards, preparing them for formal third-party review. - Compliance & Upgradability: We implement pausable functions, multi-signature controls, and upgradeable proxy patterns (like
TransparentProxyorUUPS) for secure governance.
Deploy a battle-tested MVP in 2-3 weeks or a full-featured protocol in 6-8 weeks, backed by our team's experience across DeFi, NFTs, and enterprise blockchain.
Core Gateway Capabilities We Deliver
We architect and deploy secure, scalable payment gateways that connect your business to the multi-chain economy. Each component is built for production, backed by verifiable performance metrics and security best practices.
Multi-Chain Transaction Routing
Intelligent routing logic that automatically selects the optimal bridge or chain for each payment, balancing speed, cost, and security. Supports EVM, Solana, Cosmos, and other major ecosystems.
Secure Bridge Integration
Pre-integrated, audited connections to leading canonical bridges (like Wormhole, Axelar) and liquidity networks. We implement robust security patterns and continuous monitoring for all cross-chain message flows.
Real-Time Settlement & Monitoring
End-to-end transaction tracking with sub-second status updates. Our system provides immutable proof of relay and instant failure detection with automated retry mechanisms.
Gas Optimization Engine
Dynamic fee management that predicts and bundles transactions to minimize gas costs across source and destination chains. Includes MEV protection and fee subsidy options.
Compliance & Risk Framework
Built-in modules for address screening (Sanctions, AML), transaction pattern analysis, and regulatory reporting. Configurable rules engine adapts to your jurisdiction.
Business Outcomes for Your IoT Platform
Integrate a secure, low-latency cross-chain payment gateway to unlock new revenue streams and automate financial operations for your IoT ecosystem.
Automated Micro-Payments
Enable devices to autonomously pay for data, services, or compute power across chains. We deliver smart contracts for pay-per-use models, reducing manual billing overhead by 80%.
Multi-Chain Settlement Hub
Consolidate payments from Ethereum, Polygon, and Solana into a single fiat or stablecoin settlement. Our gateway abstracts chain complexity, providing unified financial reporting.
Real-Time Revenue Streams
Monetize sensor data or API access with instant, on-chain payments. We implement streaming payment rails (e.g., Superfluid) for continuous revenue from active devices.
Enhanced Security & Compliance
Built with enterprise-grade security. Our smart contracts are audited, and we implement role-based access controls (RBAC) and transaction monitoring for regulatory adherence.
Scalable Infrastructure
Handle millions of micro-transactions daily with our optimized node infrastructure. We guarantee 99.9% uptime SLA and sub-second confirmation times for IoT-scale throughput.
Reduced Operational Cost
Eliminate traditional payment processors and manual reconciliation. Our automated settlement reduces payment processing costs by up to 60% compared to legacy gateways.

Our Development & Integration Process
A structured, milestone-driven approach designed for technical leaders. We deliver a production-ready, audited cross-chain gateway with clear timelines and zero surprises.
Architecture & Protocol Design
We architect your gateway's core logic, selecting optimal bridging protocols (e.g., CCIP, LayerZero, Axelar) and designing for security, cost-efficiency, and future composability.
Smart Contract Development
Development of secure, gas-optimized smart contracts for asset locking, messaging, and verification. Built with Solidity 0.8+, OpenZeppelin libraries, and comprehensive unit tests.
Relayer & Oracle Integration
Deployment and configuration of secure off-chain infrastructure for message relaying and price feeds. We implement multi-signature controls and automated monitoring.
Security Audit & Penetration Testing
Rigorous third-party audit by firms like Spearbit or Code4rena, followed by internal penetration testing and remediation. We provide a verifiable audit report.
Mainnet Deployment & Monitoring
Managed deployment across your target chains (Ethereum, Polygon, Arbitrum, etc.) with comprehensive monitoring dashboards, alerting, and incident response playbooks.
Documentation & Handover
We deliver complete technical documentation, operational runbooks, and conduct knowledge transfer sessions with your engineering team for full ownership.
Blockchain Infrastructure
Enterprise-grade node infrastructure with 99.9% uptime SLA and real-time monitoring.
We manage the foundational layer so your team can focus on application logic. Our infrastructure delivers multi-chain redundancy, sub-second RPC response times, and dedicated archival nodes for complex queries.
- Managed Nodes: Full RPC, validator, and archival node deployment on
EVMchains (Ethereum, Polygon, Arbitrum) andSolana. - Performance SLA: Guaranteed 99.9% uptime with 24/7 monitoring and automated failover.
- Security & Compliance: SOC 2 Type II compliant infrastructure with DDoS protection and private VPC access.
Deploy production-ready infrastructure in days, not months, with predictable costs and expert support.
Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for your payment gateway project.
We deliver a production-ready, audited cross-chain payment gateway in 4-8 weeks from kickoff. The timeline depends on the number of target blockchains and required payment methods (e.g., direct swaps, stablecoin routing). A basic 2-chain gateway with USDC/USDT support typically takes 4 weeks, while a multi-chain solution with 5+ networks and fiat on/off-ramps can take 6-8 weeks.
