# Stripe integrations

> Two ways Trails and Stripe work together: card onramp for funding, and merchant checkout that settles crypto payments in USD

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                                      |

## Getting access

Both integrations are part of [Polygon Checkout](https://polygon.technology/checkout): accept crypto payments in your existing Stripe workflow and settle in the currency you choose. Visit the page to book a demo, talk to sales, or ask about enabling Stripe for your Trails project.

For integration questions, the [Trails Telegram](https://t.me/build_with_trails) is the fastest route to the team.
