Crypto payment processing development
Modern companies are increasingly facing the need to accept cryptocurrency alongside traditional payment methods.
features
We create custom crypto payment processing solutions that can be easily integrated into any platform and allow you to manage cryptocurrency transactions safely, quickly, and conveniently.
We enable acceptance of Bitcoin, Ethereum, USDT (ERC-20 and TRC-20), BNB, and other assets. If needed, we can add non-standard tokens — you just confirm, we implement.
Each payment is automatically converted into stablecoins or fiat currencies (USD, EUR, RUB) at the current rate. Set volatility thresholds that trigger the exchange to protect funds from sharp market swings.
We provide secure REST and WebSocket APIs for issuing invoices, receiving transaction notifications, and tracking payment statuses. All data is transmitted over a secure channel and signed, eliminating the possibility of interception.
The service handles loads from tens to hundreds of thousands of transactions per minute: horizontal sharding, load balancing, and auto-scaling ensure uninterrupted operation without downtime.
- Cold storage for long-term reserves;
- Hot wallets with withdrawal limits;
- Multisignature (2-3 of 5 keys) for critical transactions;
- 2FA, IP filtering, and randomized transaction paths;
- Regular internal and external audits.
Real-time dashboards with charts, flexible filters by dates, currencies, and transaction statuses, export to CSV/XLSX/PDF, customizable invoice templates, and automatic notifications to clients.

Crypto payment processing FAQ
What does crypto processing development include?
A turnkey crypto payment system: address and invoice generation, on-chain transaction tracking, payment status webhooks, a merchant dashboard, fund withdrawal, and an admin panel.
Which cryptocurrencies and networks are supported?
BTC, ETH, and the USDT and USDC stablecoins on ERC-20, TRC-20, and BEP-20, plus other coins on request. The architecture lets you add new networks without reworking the system core.
How does the processing integrate with a website or store?
Via a REST API and webhooks: the store creates an invoice with an amount and expiry time, the customer pays to an address or QR code, and your backend receives a notification once the payment is confirmed. We also build ready-made widgets and plugins.
What happens if an invoice is underpaid or overpaid?
The logic is configurable: an acceptable deviation threshold, automatic refund, crediting a partial payment, or waiting for the remainder. The merchant receives a separate webhook event for each scenario.
Can payments be auto-converted to stablecoins or fiat?
Yes. We set up automatic conversion of incoming payments to USDT or fiat via exchanges and swap services to protect the merchant’s revenue from price volatility.
Where is the processing hosted and who controls the keys?
We deploy the system on your infrastructure (self-hosted): private keys and funds stay fully under your control, with no dependence on third-party custodial services.
