Do you support BSA/AML-aligned transaction monitoring?

Yes, we build transaction monitoring and suspicious activity reporting workflows aligned to US AML expectations for money services businesses and crypto platforms.

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 United States

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 United States, that means building to the technical expectations of High-Value Regulated Markets: Money transmission and payments activity is regulated at the state level (state MTL regimes) alongside federal BSA/AML obligations enforced by FinCEN.

United States Regulatory Landscape

What crypto payment gateway buyers in United States need to know

Money transmission and payments activity is regulated at the state level (state MTL regimes) alongside federal BSA/AML obligations enforced by FinCEN.
Crypto-asset activity intersects with both federal guidance (FinCEN, SEC/CFTC considerations) and a patchwork of state licensing regimes.
We build the technical infrastructure — KYC/AML, reporting, audit trails — that these frameworks expect, alongside qualified US regulatory counsel for licensing strategy.

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.
