What is Loop?

Loop is a crypto and stablecoin payment processor that lets you embed crypto and stablecoin payments into your software, allowing your Merchants to accept payments from Users and receive either crypto, stablecoins or fiat.

What can you do with Loop?

Accept payments for subscriptions Accept recurring crypto and stablecoin payments from Users on behalf of Merchants via a configurable embedded component and APIs without the User having to sends funds each month (i.e. unlock autopay). Merchants can be paid out in either crypto, stablecoins or fiat.

Accept payments for one-time purchases Accept one-time crypto and stablecoin payments from Users on behalf of Merchants via a configurable embedded component and send your Merchants either crypto, stablecoins or fiat.

Add on payment fee Add on additional payment processing fees that are paid from the User to the Platform at the time of payment.

Query the payment method's status before charing it Query a payment method before it is charged, allowing you to troubleshoot payment issues before they occur.

Settle in fiat Offer Users payment in crypto or stablecoin while Merchants receive fiat.

How can you integrate?

Embedded components Embed our

component directly in your UI. You have the ability to customize the styling of the embedded components - such as colors, font sizes and border radius.

API-Only You create the entire user interface and integrate payment processing via Loop API and webhooks.

What chains and tokens does Loop support?

Is there a test environment?

Yes! We support the Ethereum testnet Sepolia as well as Solana's DevNet networks for testing. You can claim free tokens using a faucet to use these networks. You can check out our crypto glossary for more information.

Do you have fees?

Yes, Loop takes a small fee from each payment as it orchestrates payment from the User to the Merchant.

Because our fees are so low, Platforms are able to add on their own fees that are deducted from the User at the time of payment and sent directly to the Platform.
