The challenge

Crypto spend products can make the cost, asset choice, and merchant settlement story hard to understand at the moment of purchase.

The approach

Model the quote and settlement process as a transparent simulation with explicit warnings and an operations view.

  • 01

    Mock authorization and quote breakdown

  • 02

    Preferred-asset selection and wallet demo mode

  • 03

    USD merchant-settlement abstraction

  • 04

    Risk, reconciliation, and analytics surfaces

Next

Keep the simulator clearly distinct from a regulated card, custody, or money-transmission product.
