White-label crypto payment gateway FAQ
A white-label cryptocurrency payment gateway is a branded service through which merchants receive crypto payments. Its implementation connects the customer payment experience with digital asset infrastructure, transaction records and merchant operations. SDK.finance provides a software foundation for building that service.
Define your merchant audience, assets, networks and settlement requirements. Map those needs to SDK.finance accounts, merchant tools and the Fireblocks integration, then scope the checkout and additional connections. Your implementation team configures, develops and tests the complete payment journey before launch.
SDK.finance supplies platform components and integrations. A complete external-wallet-to-merchant-invoice checkout is assessed as a project workflow. Invoice matching, payment expiry, underpayments, refunds and merchant notifications must be explicitly included and tested in your implementation scope.
A gateway focuses on merchant payment acceptance and the handling of payment requests. A wallet focuses on holding and moving a user’s assets. If your primary goal is a consumer application with conversion features, explore our crypto-to-fiat software.
If you are planning a stablecoin payment gateway for USDT or USDC, specify the token and blockchain network, deposit and withdrawal requirements, and settlement currency. The team can assess provider support, configuration and development needs for that exact flow. Support is confirmed per asset and network.
Cost depends on the platform licence, deployment model, checkout and portal customisation, integrations and testing. Budget separately for custody, blockchain network fees, conversion, payouts and ongoing operations. Request an estimate against your merchant payment flow and target markets.
SDK.finance offers a commercial source code licence for its backend. For a self-hosted crypto payment gateway project, confirm the licensed components, deployment architecture and custom development scope. Source code access does not include ownership of Fireblocks or other third-party systems and is not an open-source licence.
The documented integration covers crypto custody connections, deposit and withdrawal processing, asset configuration and blockchain confirmation status handling. Linking an incoming blockchain payment to a specific merchant invoice is a separate workflow to assess and implement for your gateway.
Crypto-to-fiat settlement requires a defined conversion and payout flow with suitable providers. Specify the settlement currencies, destinations and timing you need. Provider availability, commercial agreements, account mapping and development scope are evaluated for the project; fiat settlement is not assumed from crypto deposit support.
SDK.finance provides software controls such as roles, permissions and verification integrations. Your project must assign responsibilities for custody, access policies, merchant verification, transaction screening and operational controls across your organisation and providers. Confirm any required KYT or Travel Rule tooling in the agreed scope.
SDK.finance provides 650+ APIs for connecting applications and extending platform workflows, alongside webhook mechanisms for external events. During technical evaluation, map the APIs and event handling needed for your checkout, merchant portal and provider connections. Review the integration catalogue and documentation with your developers.
The timeline depends on the fit with available platform functionality, provider onboarding, checkout development, asset configuration, testing and deployment. Agree milestones after reviewing the end-to-end merchant payment flow. A platform deployment and a production-ready crypto gateway are different delivery milestones.
It suits PSPs, fintech teams and digital asset businesses planning their own branded merchant payment service. It is most relevant when you need control over your software, interfaces and integrations. For a broader card and bank payment proposition, explore our white-label payment gateway software.
