Use the standalone onrampPublic preview

Generate a redirect URL and mint a session for the standalone onramp.

The Stripe-hosted, standalone onramp is a prebuilt frontend integration of the crypto onramp hosted at https://crypto.link.com. Platforms can integrate the crypto onramp by redirecting their users to the standalone onramp, rather than hosting an embedded version of the onramp within their application.

Before you begin

To access the Onramp API, including testing environments, you must follow these steps to submit your application. We review most onramp applications within 48 hours.

Create or sign in to your Stripe account and submit the onramp application.
Complete your Stripe application.
After submitting the application, start development using testing environments.

We notify you when your application is approved or if we need more information. You can check your application status anytime by visiting the onboarding page.

No code standalone onramp

The standalone onramp redirect URL supports parameter customization and lets you prefill fields such as the destination currency and the source amount or destination amount.

Share the link by sending it directly to users or by displaying it with a button, as in the following demo.

Generate a redirect URL with code

return (
  <a href={redirectUrl}>
    Buy Crypto
  </a>
);

Customize the standalone onramp

You can also generate a redirect URL with code using the Standalone function and passing in the desired fields. Choose to either generate a redirect URL or mint a session with a redirect URL:

Customization option	Overview	Best for
Generate a redirect URL	Generate a redirect URL in the frontend without a Stripe account. Customize the suggested source or destination amount, destination currency, and network.	If you want a lightweight front-end integration with light customization and no branding.
Mint a session with a redirect URL	Mint a session with a redirect URL in the backend with a Stripe account. Allows full customization, including the destination wallet address. For a full list of parameters, see Pre-populate transaction parameters.	If you want a fully customized onramp with branding.

Generate a redirect URL

Include the following scripts using script tags within the <head> element of your HTML. These scripts must always load directly from Stripe domains (https://js.stripe.com and https://crypto-js.stripe.com) for compatibility and PCI compliance. Don’t include the scripts in a bundle or host a copy yourself. If you do, your integration might break without warning.

<head>
  <title>Onramp</title>
  <script src="https://js.stripe.com/basil/stripe.js"></script>
  <script src="https://crypto-js.stripe.com/crypto-onramp-outer.js"></script>
</head>

Generate a redirect URL using the Standalone function, passing in the desired parameters:

const standaloneOnramp = window.StripeOnramp.Standalone({
  source_currency: 'usd',
  amount: {source_amount: '42'},
  destination_networks: ['ethereum', 'bitcoin'],
  destination_currencies: ['eth', 'btc'],
  destination_currency: 'btc',
  destination_network: 'bitcoin'
});
const redirectUrl = standaloneOnramp.getUrl();

You can pre-populate these parameters:

source_currency: The fiat currency for the transaction (usd and eur).
amount: The fixed amount of fiat currency or cryptocurrency for this purchase. Specify a fiat amount by passing in source_amount ({source_amount: 42}) . Specify a cryptocurrency amount by passing in destination_amount ({destination_amount: 42}). You can only specify one amount.
destination_currencies: An array of cryptocurrencies you want to restrict to (['eth', 'usdc']).
destination_networks: An array of crypto networks you want to restrict to (['ethereum', 'polygon']).
destination_network: The default crypto network for this onramp (ethereum).
destination_currency: The default cryptocurrency for this onramp session (eth).

Redirect your users to the URL for a prebuilt front-end integration of the crypto onramp on the standalone onramp.

Mint a session with a redirect URL

Similar to other integrations, you need to implement a server endpoint to create a new onramp session for every user visit. The onramp session creation request returns a redirect_url. Redirect your users to the URL for a fully customized and branded crypto onramp on the standalone onramp.

Generate a crypto onramp session with a redirect_url by running the following curl command:

Command Line
curl -X POST https://api.stripe.com/v1/crypto/onramp_sessions \
  -usk_test_BQokikJOvBiI2HlWgH4olfQ2
:

You receive a response similar to the following:
