What is a crypto payment gateway?
A crypto payment gateway lets merchants accept Bitcoin, Ethereum and stablecoins such as USDT and USDC, with instant conversion to fiat if required. NNT Software builds white-label and custom crypto payment gateways with merchant dashboards, plugins, payouts, KYT screening and settlement reporting.

Crypto Payment Gateway development cost and timeline
A production-ready crypto payment gateway is priced as per your requirements and budget, with a first release in 10–16 weeks.
The final cost of crypto payment gateway depends on five main factors: the number of user roles and screens, the integrations required (payments, identity, ERP, CRM, messaging), compliance and security requirements, the seniority mix of the team, and the engagement model.
We always start with a short discovery phase so the estimate you receive is fixed and written, not a vague range. Ongoing maintenance and hosting typically add 15–20% of the build cost per year.
| Phase | What is delivered | Indicative duration |
|---|---|---|
| Discovery | Scope, prototype, architecture | 1–3 weeks |
| MVP build | Merchant onboarding, Checkout & plugins, Stablecoin rails | 10–16 weeks |
| Hardening | Security testing, performance, compliance | 2–4 weeks |
| Growth | Auto-conversion, Payouts, Compliance | Ongoing |

How we deliver crypto payment gateway projects
Every crypto payment gateway engagement follows the same disciplined, transparent process. You always know what is being built, what it costs and what comes next.
1. Discovery and scoping (1–2 weeks)
Workshops with your stakeholders to understand goals, users, workflows and constraints. We document requirements as user stories, map integrations and agree success metrics, then share a written scope, milestone plan and fixed estimate for crypto payment gateway.
2. UX and architecture (1–3 weeks)
Designers produce user flows and a clickable prototype while architects choose the stack, hosting, data model and security controls. Nothing is built until you sign off the prototype and architecture.
3. Agile development (two-week sprints)
Developers build in short sprints with a demo at the end of each one. You see working software early, give feedback continuously and can reprioritise the backlog at any time.
4. Quality assurance
Dedicated QA engineers write test cases, run manual and automated regression tests, check performance and review security basics before every release. Defects are tracked openly.
5. Launch
We deploy with zero-downtime pipelines, migrate data if needed, monitor closely during the first days and train your team or users.
6. Support and growth
After launch, SLA-backed support covers bug fixes, monitoring, security patches and continuous improvement, so the product keeps improving as your business grows.
