Crypto Payment Gateway
Development That Delivers
Build production-ready crypto payment gateways that process BTC, ETH, and 50+ tokens with sub-second settlement confirmation. Our engineers deliver PCI DSS Level 1 certified systems handling 500K+ monthly transactions at 99.9% uptime across multi-chain architectures.
What a Production Crypto Payment Gateway Development Project Delivers
A crypto payment gateway sits between a customer's wallet and a merchant's settlement account. It accepts Bitcoin, Ethereum, USDT, USDC and other tokens, prices the transaction at the moment of checkout, runs the compliance checks your jurisdiction requires, confirms the transaction on-chain, and routes the settled value to wherever your treasury actually wants it: stablecoin, fiat, or back into a hot wallet for immediate working capital. The hard part is not accepting the payment. The hard part is doing it at PCI DSS Level 1 standards while staying inside FATF AML rules and not losing money to volatility, fraud, or chargebacks.

Crypto Payment Gateway API & Developer Tools
Production-grade REST and GraphQL APIs, typed SDKs, and real-time event streams that connect your platform to a fully operational crypto payment gateway in days, not months.
REST API for Payment Processing
Fully-documented RESTful API covering the complete payment lifecycle: payment intent creation, transaction confirmation, refund initiation, and settlement status. Versioned endpoints with semantic release cycles mean your integration never breaks due to upstream changes. OpenAPI 3.0 spec ships with every release, compatible with any code generator or API client.
Webhook Event Streams
Push-based webhook notifications fire on every state transition in your payment pipeline: payment.received, payment.confirmed, payment.failed, settlement.completed, chargeback.opened. Signed payloads use HMAC-SHA256 so your server can verify authenticity. Configurable retry logic with exponential backoff ensures no event is silently dropped during outages.
Typed SDK Libraries
Official SDK libraries for Node.js, Python, Go, and PHP with full TypeScript definitions and inline documentation. Each SDK wraps the REST API with typed request/response objects, automatic retry logic, and built-in idempotency key management so your engineers integrate the crypto payment gateway API without reading raw HTTP specs.
GraphQL Query Interface
GraphQL endpoint lets client applications query transaction history, settlement reports, and currency exchange rates in a single round-trip. Introspection schema and playground are available in staging. Subscriptions deliver real-time payment confirmation events directly to your front-end without a separate WebSocket integration layer.
WebSocket Live Feeds
Persistent WebSocket connections push real-time transaction updates to your merchant dashboard, removing the need for polling. Channels are scoped per merchant or per payment session so a single connection can monitor an entire portfolio. Automatic reconnect and message replay guarantee no event loss during brief network interruptions.
Full Sandbox Environment
Isolated sandbox with testnet wallets for BTC, ETH, USDT, and USDC lets your engineers simulate the complete payment lifecycle without touching real funds. Faucet API mints test tokens on demand. Sandbox mirrors production API structure exactly, so code written against sandbox deploys to production without modification.

Security That Holds Up in Audit
The six security layers that protect every transaction and pass external review
End-to-End Encryption
AES-256 encryption protects all data in transit and at rest. Hardware Security Modules store private keys in tamper-resistant enclaves, and rotating key schedules prevent long-term exposure if a single key is ever compromised.
ML Fraud Detection
Machine learning models score every transaction in real time against behavioral patterns, velocity limits, and known threat signatures. Flagged payments route to a review queue or auto-reject based on your configurable risk thresholds.
Regulatory Compliance
Built-in compliance framework covering PCI DSS Level 1, GDPR data residency, AML transaction monitoring, and SOX audit trails. Jurisdiction-specific rule engines apply the correct screening and reporting requirements automatically based on merchant registration country and customer geography.
24/7 Security Monitoring
Prometheus and Grafana dashboards track system health around the clock with per-service granularity. PagerDuty alerts fire on anomaly detection, and automated runbooks contain threats within minutes so your payment flow stays uninterrupted during incidents.
Multi-Factor Authentication
TOTP-based multi-factor authentication, role-based access control with granular per-endpoint permissions, and SSO integration via SAML 2.0 and OpenID Connect ensure only authorized personnel reach critical payment infrastructure and sensitive wallet signing operations.
Disaster Recovery
Automated point-in-time backups replicate to geographically separate AWS regions every six hours. Hot failover switches traffic in under 30 seconds, and quarterly disaster recovery drills verify that your recovery time objective stays below four hours.
Why Teams Choose Our Crypto Payment Gateway Development
Our engineers have shipped 150+ payment integrations across DeFi, retail, and B2B fintech. We pair deep protocol knowledge with strict regulatory compliance, so the gateways we ship process real volume without downtime or audit failures.
FinTech Expertise
Our payment engineers have built gateways for licensed exchanges, neobanks, and PSPs across 12 jurisdictions. They understand settlement mechanics, float management, and the difference between custodial and non-custodial architectures at the protocol level. That hands-on experience means fewer surprises during development, more accurate cost estimates, and a significantly faster path from kickoff to a production-ready gateway handling real merchant volume.
Multi-Currency Support
We wire up BTC, ETH, USDT, USDC, and 50+ ERC-20 and BEP-20 tokens through a unified payment abstraction layer. Rate-locking happens at the moment of checkout, settlement routing is configurable per merchant or per transaction, and adding new chains or token standards post-launch takes days instead of months because the multi-chain adapter architecture is designed into the core from day one.
Enterprise Security
Every gateway ships with AES-256 encryption, HSM-backed key storage, multi-signature wallet architecture, and PCI DSS Level 1 certification. Real-time ML fraud scoring evaluates every inbound transaction against velocity checks, geo-risk signals, and behavioral baselines. All of this is in the architecture from the first commit, not bolted on at the end.
Scalable Architecture
Our gateways run on event-driven microservices backed by Apache Kafka, Redis, and PostgreSQL with read replicas. This stack handles 500K+ monthly transactions at 99.9% uptime today and scales horizontally by adding consumer instances when your volume grows. Geographic load balancing across multiple AWS regions keeps API latency under 200ms for merchants and their customers anywhere in the world.
Regulatory Compliance
We embed PCI DSS, AML/KYC, GDPR, and SOX controls directly into the transaction flow rather than bolting them on as an afterthought. Jurisdiction-specific rule engines apply the correct screening, reporting, and data residency requirements automatically per market, so your compliance team gets audit-ready logs and your merchants never encounter unnecessary friction during onboarding or settlement.
24/7 Support
Our operations team monitors every gateway around the clock using Prometheus, Grafana, and PagerDuty. Incident response follows documented runbooks with defined SLAs where P1 issues get a human response in under 15 minutes. We also handle rolling upgrades, security patches, dependency updates, and TLS certificate rotations so your internal team can stay focused on growing the business instead of firefighting infrastructure.
