Question 1

What is a payment adapter?

Accepted Answer

A payment adapter is a self-contained software component that handles the full communication layer between your processing system and a payment method or provider. It manages protocol translation, authentication, request signing, retry logic, and webhook delivery — so your backend only speaks one standard interface regardless of how many payment providers you connect to. randn.tech provides pre-built, production-ready adapters that deploy on your own infrastructure in hours rather than months.

Question 2

Payment adapter vs payment gateway — what's the difference?

Accepted Answer

A payment gateway is a hosted service you route transactions through — it controls the infrastructure and you depend on their availability, pricing, and data policies. A payment adapter is a software component you deploy on your own servers: you own the infrastructure, the data stays in your environment, and you're not locked into any vendor. randn.tech adapters give you gateway-level functionality without the vendor dependency, making them a better fit for fintech companies and banks that require data sovereignty and infrastructure control.

Question 3

How long does payment integration typically take?

Accepted Answer

A custom payment integration built from scratch typically takes 10–14 weeks from kickoff to production — covering API research, protocol implementation, QA, certification, and launch prep. With randn.tech pre-built adapters, most teams go from selection to a working production environment in 48 hours: roughly 2 hours of configuration, 4 hours of internal testing, and 1 hour of deployment. The adapter handles all the protocol complexity so your team focuses on business logic, not wire formats.

Question 4

Can I self-host a payment gateway on my own infrastructure?

Accepted Answer

Yes. randn.tech adapters are distributed as Docker containers or standalone binaries that run on any infrastructure — your cloud account, on-premise servers, Kubernetes clusters, or bare metal. There is no call-home, no cloud dependency, and no data leaving your environment.

Question 5

How much does a custom payment integration cost?

Accepted Answer

Building a single custom payment adapter in-house typically costs $50,000–$75,000 in engineering time, QA, compliance review, and production hardening — before accounting for ongoing maintenance. Teams also spend 10,000+ lines of integration code per provider. randn.tech adapters reduce the total cost to $10,000–$30,000 through pre-built components that replace months of custom development, and a single YAML configuration file replaces thousands of lines of bespoke integration code.

Question 6

How do I integrate a payment provider without custom development?

Accepted Answer

randn.tech adapters use a declarative configuration model: you describe the connection parameters in a YAML file — endpoints, credentials, transform rules — and the adapter handles the rest. No protocol knowledge is required. The adapter translates between your processing system's interface and the payment provider's API, signs requests, manages retries, and delivers webhooks. Your team doesn't need to read API documentation or implement provider-specific edge cases — that's already built into the adapter.

Question 7

What payment methods does randn.tech support?

Accepted Answer

randn.tech adapters cover a broad range of payment methods: card rails (Visa, Mastercard, local schemes), PSPs and gateway aggregators, digital wallets (Apple Pay, Google Pay, Alipay, WeChat Pay), bank transfers (SEPA, SWIFT, local ACH equivalents), QR-based payments, BNPL providers, and crypto rails. If a payment method your business requires is not yet in the catalog, we build the adapter at our own cost and make it available for licensing once released — simply send us the provider documentation.

Question 8

Is randn.tech suitable for banks and financial institutions?

Accepted Answer

Yes. randn.tech was designed with the operational requirements of banks and regulated institutions in mind. Adapters deploy entirely on-premise or in your private cloud with no external dependencies, support mutual TLS authentication, operate within your existing compliance perimeter, and expose Prometheus metrics and OpenTelemetry traces for your internal monitoring stack. The architecture avoids vendor lock-in and keeps all transaction data inside your controlled environment — making it compatible with PCI-DSS, GDPR, and local regulatory frameworks across EU and APAC markets.
