Stripe integrations - Trails

Trails integrates Stripe in two directions. Both are enabled per project on the Trails API side, and neither puts a Stripe key in the browser.

	Stripe onramp	Stripe checkout
Who pays	A user buying crypto with a card	A shopper paying with crypto they already hold
Money flows	Fiat card → USDC on Base → the intent’s destination	Any token on any EVM chain → USDC deposit → USD on the merchant’s Stripe account
Where it shows up	A Pay with Stripe tile in the funding and payment method lists	The whole widget becomes the payment step of a merchant checkout
What you configure	Nothing, or `onramp.stripe.environment` for the sandbox	The `stripe` prop: a price in cents and an order reference
Merchant setup	Stripe enabled for the project	A Stripe merchant key mapped to the project

Stripe onramp

Let users fund a Trails intent with a card. Available in fund, swap and pay modes.

Stripe checkout

Accept any token on any EVM chain and settle in USD via Stripe pay-with-crypto. One widget prop, no merchant backend.

Getting access

Both integrations are part of Polygon Checkout: accept crypto payments in your existing Stripe workflow and settle in the currency you choose.
