Yes, we design custody, reporting, and governance architecture aligned to the technical expectations emerging under MiCA and BaFin guidance.

Can you help modernize our legacy banking core?

Yes, we specialize in incremental core modernization that avoids a risky big-bang rewrite while meeting German banking supervisory expectations.

Do you build GDPR-aligned data architecture?

Which cryptocurrencies can the gateway accept?

Bitcoin, Ethereum and major stablecoins by default; additional chains can be added based on your markets.

How long does integration take?

A standard stablecoin payment gateway typically takes 6–10 weeks depending on the number of chains and compliance checks.

Can this integrate with our existing checkout?

Yes, via REST APIs and webhooks designed to slot into existing checkout, ERP and accounting systems.

Is the gateway PCI-DSS aligned?

Where fiat rails are involved, we follow PCI-DSS-aligned handling practices and recommend a certified payment partner.

Crypto Payment Gateway & Stablecoin API Integration in Berlin

Cross-border settlement through banks is slow and expensive. Hurain Technologies builds multi-chain crypto payment gateways and stablecoin APIs that let businesses accept Bitcoin, Ethereum, USDT, USDC and other digital currencies directly, settling in minutes instead of days with instant conversion and built-in AML screening. In Berlin, that means building to the technical expectations of the local market.

Berlin Market Landscape

Why crypto payment gateway is critical in Berlin

Berlin hosts one of Europe's largest concentrations of crypto-native founders and Web3 startups, distinct from Frankfurt's traditional banking focus.
Lower operating costs than London or Zurich have made Berlin a preferred base for early-stage blockchain teams serving the broader EU market.
Berlin startups frequently need architecture that satisfies both BaFin's German expectations and broader EU MiCA alignment as they scale across the bloc.

The Challenge

Problems we see teams struggling with

Cross-border payment friction

Traditional wires are slow, expensive, and limited to banking-friendly markets.

Limited market access

Card and wire infrastructure doesn't reach unbanked regions where crypto provides a clear alternative.

No unified crypto/fiat checkout

Offering crypto alongside traditional payment methods requires disconnected integrations.

Compliance & settlement risk

Customer balances must be screened and settled reliably without custody overhead.

Volatility exposure from holding crypto

Businesses that don't convert incoming crypto to fiat quickly take on price risk they never intended to carry.

Reconciliation complexity across chains

Accepting payments across multiple blockchains without a unified settlement layer turns month-end reconciliation into a multi-system nightmare.
