Convert user payments to your preferred stablecoin (USDC, USDT) or native token in real-time. Eliminate volatility risk and treasury management overhead with automated settlement.
Enterprise Security & Compliance
Smart contract audits by Halborn, MPC-based custody, and automated AML/KYC screening via Chainalysis. SOC 2 Type II compliant infrastructure for regulated entities.
Gas Optimization & Cost Management
Intelligent gas fee estimation and batch transaction processing reduce your operational costs by up to 40%. Set custom fee policies and receive detailed cost analytics.
Custom Checkout & Branding
Fully customizable, embeddable checkout widgets and hosted payment pages. Maintain your brand identity while we handle the payment processing and security.
Business Outcomes: Beyond Technical Integration
Our multi-asset payment aggregator delivers measurable business results, not just API endpoints. We focus on outcomes that accelerate your growth and reduce operational overhead.
Accelerated Time-to-Revenue
Go live with a production-ready payment gateway in under 3 weeks. Our pre-built connectors and battle-tested infrastructure eliminate months of development, letting you capture market share faster.
Reduced Operational Complexity
Consolidate settlement, reconciliation, and compliance for 50+ blockchains into a single dashboard. Automate treasury management and reporting, cutting back-office costs by up to 70%.
Enterprise-Grade Security & Compliance
Deploy with confidence. Our infrastructure is built on SOC 2 Type II principles, features MPC-based key management, and undergoes regular audits by firms like Halborn. We handle the security burden.
Optimized Transaction Economics
Dynamically route payments across liquidity sources and L2s to achieve the lowest possible fees and fastest finality. Our algorithms consistently deliver sub-2-second finality and fee savings of 15-40%.
Scalable Global Infrastructure
Our globally distributed node network guarantees 99.95% uptime SLA with automatic failover. Scale to handle millions of transactions daily without performance degradation or manual intervention.
Future-Proof Payment Stack
Stay ahead of market shifts. We provide instant integration for new tokens, emerging L2s, and novel payment methods (like account abstraction), ensuring your platform never becomes obsolete.

Our Delivery Methodology
We deliver production-ready payment infrastructure through a structured, transparent process designed for technical founders and CTOs. Each phase is built on our experience deploying for 50+ FinTech clients.
Architecture & Discovery
We conduct a technical deep-dive to design a scalable, multi-chain architecture. We define token standards (ERC-20, ERC-1155), settlement layers (EVM, Solana), and integration points for your existing stack.
Smart Contract Development
Our engineers build secure, gas-optimized smart contracts in Solidity/Rust. All code follows OpenZeppelin standards and includes comprehensive unit/integration testing before our internal audit.
Security & Audit Integration
We integrate with leading audit firms (e.g., Trail of Bits, Quantstamp) to schedule formal audits. We manage the entire process, from scoping to remediation, ensuring no critical vulnerabilities reach production.
API & SDK Development
We build the merchant-facing REST APIs and developer SDKs (Node.js, Python) that abstract blockchain complexity. Includes webhook systems for real-time payment status and comprehensive documentation.
Staging & Integration Testing
We deploy to a dedicated staging environment that mirrors production. We execute end-to-end test flows across all supported chains (Ethereum, Polygon, Solana) and payment methods before go-live.
Production Deployment & Monitoring
We manage the mainnet deployment and provide 24/7 monitoring via Datadog/Grafana dashboards. We set up alerts for transaction failures, gas spikes, and wallet balance thresholds.
Smart Contract Development

Frequently Asked Questions
Get specific answers on timelines, security, and integration for your payment solution.
A standard multi-asset payment aggregator deployment takes 3-5 weeks from kickoff to production. This includes smart contract development, frontend integration, testing, and security audit integration. Complex requirements like custom token whitelisting or multi-chain settlement may extend this by 1-2 weeks. We provide a detailed sprint plan within the first week of engagement.
