Payment architecture

How crypto payments work

Choose the route that fits your risk controls, customer base, and treasury process. The technical design comes first.

01

Choose the route

Accept payment to a managed wallet, a direct address, or a processor account.

02

Select the asset

Support selected cryptocurrencies or stablecoins with clear network rules.

03

Confirm the order

Pass transaction states back to the checkout, fulfilment, and customer records.

04

Settle funds

Send funds to fiat or crypto settlement accounts on a schedule you control.

Crypto checkout development

Keep the checkout familiar.

Customers see the amount, network, wallet prompt, and status in one focused screen. Your existing order flow receives a useful result instead of a chain of manual checks.

  • Embedded payment buttons and QR code generation
  • Live transaction states with clear customer messages
  • Fallback handling when a payment expires or fails
  • Mobile-first screens for wallet users

Pay with digital assets

USDC on a supported network

Scan to continue on mobile

Network, amount, and expiry details stay visible before confirmation.

Connectivity

Wallet and exchange connections that fit your stack.

Direct blockchain integration is useful when you need control. A processor is useful when you need operational simplicity. We map both options before implementation starts.

Custodial and self-custody

Connect wallet providers with permissions, address checks, and clear ownership boundaries.

Exchange APIs

Bring liquidity and conversion data into the payment and treasury workflow.

Automated settlement

Set rules for timing, asset choice, destination accounts, and reconciliation records.

Multi-currency support

Present approved assets while keeping network and pricing logic under control.

Compliance-aware technical planning

Payment software needs useful connection points for the teams that review identity, risk, and transaction activity. We build the technical layer. We don't provide legal advice.

KYC and AML provider integration points

Transaction monitoring and reporting hooks

Data minimisation and privacy considerations

Useful records

Keep payment IDs, wallet addresses, network data, and settlement references available for authorised teams.

Clear controls

Define approved assets, confirmation thresholds, expiry windows, and exception handling.

Built for review

A well-documented integration gives your compliance and operations teams a clear view of what the software does and where their providers connect.

Business case

Why add cryptocurrency payments?

The right payment route can remove friction for a specific customer group and make international settlement easier to manage.

Reach technical customers

Give wallet users a payment method that matches how they already hold digital assets.

Review payment costs

Compare network fees, processor charges, chargeback exposure, and reconciliation work in one model.

Sell across borders

Accept selected digital assets without asking every customer to navigate a separate currency conversion.

Settle with stablecoins

Use stablecoin settlement where it suits your treasury process and approved operating model.
