About the app

How Helio works with Arca
Helio provides crypto checkout pages and pay links for merchants and creators. Helio controls the invoice, supported assets, networks, payment status, and any account requirements. If a Helio checkout supports a token and network that match Arca, Arca can help you review the payment details or wallet request before you approve or send.
