Crypto payment gateway

Crypto payment gateway, routed like fiat — through one API and one ledger.

topropay surfaces stablecoin and major-token acceptance through licensed partner gateways and settles the result alongside card and bank rails. Crypto becomes another payment method in the same unified API — quoted, captured and reconciled on the same daily feed.

The short version

Why a crypto payment system belongs on the same orchestration layer as card

For most merchants, crypto acceptance has been the awkward second integration — a separate plugin, a separate dashboard, a separate reconciliation file and a separate compliance review. The reasoning was structural: crypto payment processing didn't share a control plane with card or bank-rail processing, so each piece was maintained as its own project.

topropay collapses that. Crypto rails are connected through the same orchestration layer that handles cards, wallets, APMs and bank rails — exposed as another method behind the unified API, with the same authorisation verbs, the same webhooks and the same daily settlement feed. The shopper picks how to pay; the merchant decides what to settle into; the finance team closes the month from a single ledger.

This page covers what the gateway covers, how the flows work end-to-end, which merchants get the most out of crypto acceptance and what the platform's compliance posture is around stablecoins, networks and KYC.

Key benefits

What changes when you accept crypto payment through orchestration

Four outcomes show up consistently once stablecoin and major-token acceptance share a control plane with the rest of the payment rails — from engineering all the way through treasury and compliance.

  • Crypto payment processing on the same API as fiat

    topropay treats crypto as another payment method in the unified API: the same authorisation, capture and refund verbs apply, the same webhooks fire, and the same reconciliation feed lands in the finance warehouse. Your engineering team doesn't learn a second SDK.

  • Stablecoin-first settlement, conversion as policy

    Conversion-on-receipt rules are configurable per merchant and per asset. Keep USDC and USDT as stablecoin balances; auto-convert BTC and ETH to fiat at acceptance; or hold a portion of receipts as crypto and settle the rest — the policy lives in the dashboard, not in a treasury script.

  • Card to crypto payment gateway, both directions

    Customers can pay by card and have the merchant settle in crypto (card-in, crypto-out) or pay in crypto and have the merchant settle in fiat (crypto-in, fiat-out). Both directions use the same vault, the same routing engine and the same dispute timeline.

  • Regulated partners only, KYB by default

    topropay connects crypto payment rails through licensed partner gateways with full KYC/KYB on the merchant side. The platform's compliance posture extends to crypto: every merchant is identified, every flow is logged and every counterparty is regulated where the law requires.

How it works

End-to-end crypto payment processing in four stages

What actually happens between a shopper picking the crypto tile and the merchant seeing the receipt land in tomorrow's settlement file.

  1. 01

    Quote

    The shopper picks a token. The gateway returns a price quote pegged to the merchant's settlement currency, valid for a short window.

  2. 02

    Pay

    The shopper pays in crypto from a wallet or pays by card and the gateway converts the card charge into the merchant's chosen settlement asset.

  3. 03

    Confirm

    On-chain confirmations gate capture. The merchant configures the threshold per token; webhooks fire on first sight and on full confirmation.

  4. 04

    Settle

    Stablecoin balances accumulate or convert; fiat settlements roll into the same daily file as card and bank-rail receipts.

Main use cases

Where a crypto payment gateway for website and back-office flows earns its keep

Same gateway; different shapes of merchant. Four cases that cover most of the crypto-acceptance traffic we see today.

  • Subs

    Subscription products with crypto-paying customers

    A subscription product that lets some customers pay in USDC and others pay by card runs both flows through one API. Renewals on crypto tokens behave like network-token renewals on cards — programmatic, retriable and reconciled into one ledger.

  • DTC

    DTC checkout with a crypto payment plugin alternative

    Instead of installing a separate crypto payment plugin per storefront, the same hosted checkout that powers card and APM payments exposes the crypto option as another tile. One surface, one set of webhooks, one PCI-compliant flow next to a partner-licensed crypto flow.

  • B2B

    B2B invoicing and cross-border settlement

    Invoices issued in fiat can be paid in stablecoin, with the gateway handling the conversion to the merchant's settlement currency. Particularly useful for cross-border B2B where stablecoin rails materially compress settlement time vs correspondent banking.

  • PSP

    PSPs and platforms surfacing crypto downstream

    Resell aggregated crypto capacity to your own merchants. Their checkout inherits the routing, the reconciliation and the compliance posture; you keep the merchant relationship and the pricing.

Trust & compliance

Compliance posture across crypto payment rails and fiat

Every flow runs through licensed partner gateways. Merchants integrate as sub-merchants and inherit the platform's compliance posture rather than having to stand up a parallel one for crypto.

  • PCI DSS Level 1 service-provider posture across the underlying card and bank-rail traffic.
  • Crypto rails delivered through licensed partner gateways — not a single in-house wallet.
  • Per-merchant KYB at onboarding; per-transaction screening on supported flows.
  • Travel-rule data captured and forwarded where the destination jurisdiction requires it.
  • Signed event delivery on every state transition, exported into your SIEM or warehouse.
  • Per-region and per-asset toggles, so a merchant can switch a single network off without redeploying.

Frequently asked

Buyer questions about crypto payment processing on topropay

The questions buyers actually ask — about coverage, compliance, integration shape and the awkward edges of crypto acceptance.

Is topropay a crypto payment gateway, or does it pass through to one?
topropay is the orchestration layer in front of a crypto payment gateway: we expose a unified API that surfaces the crypto option alongside card and bank rails, while the actual on-chain processing runs through licensed partner gateways. From your code it looks like one gateway; from compliance it's the partner that holds the relevant licences for the assets and regions you accept.
Some queries spell this 'crypto payment gatway' — is that the same product?
Yes — the misspelling 'crypto payment gatway' refers to the same product. The page covers it under its correct spelling (crypto payment gateway) and the underlying flow is identical regardless of how the search was typed.
What does crypto payment procesing involve operationally?
Crypto payment procesing (sometimes spelt without the double-'s' in search queries) breaks into the same operational stages as card processing: quote, authorise, confirm, settle. The difference is what gates the capture — for crypto it's on-chain confirmations rather than a card-network response. The merchant configures the confirmation threshold per token in the dashboard.
Can topropay act as the crypto gateway for a merchant's website?
Yes. The crypto gateway flow is exposed as a hosted checkout surface that drops into any website with a single integration step, or as a direct API for merchants that want full control over the surface. Either way the merchant treats it as the gateway from a contract perspective; topropay handles the connectivity to the licensed partner gateways underneath.
How do customers accept crypto payment in practice?
From the merchant side, 'accept crypto payment' means turning the crypto option on inside the dashboard, selecting the assets to support and (optionally) configuring conversion-on-receipt policies. From the shopper side, it means picking the crypto tile at checkout, scanning a QR code or pasting an address from their wallet, and watching on-chain confirmations roll in.
Is this a crypto payment system or a wallet?
It is a crypto payment system, not a wallet. topropay does not hold customer funds in a consumer-facing wallet; the partner gateways receive funds and settle them to the merchant according to the configured policy. Merchants that need self-custody integrate with their own wallet on the receipt side.
Is there a crypto payment gateway without kyc option?
No — topropay does not offer a crypto payment gateway without kyc setup. Every merchant goes through KYB onboarding before live keys are issued, and partner gateways apply travel-rule and counterparty controls per the jurisdictions they cover. We are transparent about this because no-KYC processing is incompatible with the licensed-operator framework the platform is built on. Merchants that need a no-KYC flow are better served elsewhere.
Which crypto payment methods are supported on day one?
Day-one crypto payment methods cover the leading stablecoins (USDC, USDT, DAI, and EURC where the partner gateway supports it) and the four major tokens (BTC, ETH, LTC, BCH). Networks under the hood include Ethereum L1, Polygon, Arbitrum, Base, Solana and Tron. The exact list per merchant depends on the regions and partner gateways enabled on the contract.
Do you need a vps crypto payment node or any infrastructure on the merchant side?
No vps crypto payment node is required. topropay is a SaaS platform — there's no self-hosted gateway to maintain, no VPS to provision, no full-node software to run on the merchant side. Connectivity is HTTPS-only; on-chain operations sit with the licensed partner gateways.
How does card to crypto payment gateway acceptance work?
Card to crypto payment gateway acceptance lets a shopper pay with a card and the merchant receive the equivalent in crypto, or vice versa. topropay's routing engine handles the conversion side through the connected partner gateways; the merchant configures whether settlement lands in fiat, in stablecoin or in a mix. Refunds and chargebacks on the card side are reconciled against the converted crypto balance.
Is there a packaged crypto payment gateway for website integration?
Yes — the crypto payment gateway for website integration is the same hosted checkout that powers card and APM acceptance, with crypto as an additional method tile. One snippet of code embeds the checkout; the rest is dashboard configuration. There is no separate crypto-only script to maintain.
Do you provide a crypto payment plugin for popular CMS platforms?
topropay's crypto payment plugin path goes through the same e-commerce connectors that surface card and APM acceptance — the crypto method is enabled in the dashboard and appears as another option inside the existing plugin. We avoid shipping a separate crypto-only plugin because keeping two plugins in step over a CMS's release cadence creates more breakage than it prevents.
What separates a top crypto payment gateway from the long tail?
A top crypto payment gateway, in our reading, gets four things right: licensed connectivity (not a grey-market wallet), explicit conversion policies (not opaque mid-market markups), payment rails that span both crypto and fiat (not crypto-only with awkward off-ramps) and a reconciliation feed that fits into existing finance workflow. topropay's design optimises for that fourth point in particular — crypto receipts shouldn't require a second close every month.
How do crypto payment rails interact with the rest of topropay's payment rails?
Crypto payment rails sit alongside card, bank and APM rails in the same orchestration layer. The routing engine doesn't route between crypto and card per transaction (the shopper picks one), but the back-end treats both consistently: same webhooks, same dispute timeline (where applicable), same daily reconciliation export.
