What is a crypto payment processor?

A crypto payment processor facilitates digital transactions between merchants and their customers enabling merchants to accept various forms of crypto payment. Merchants that accept crypto payments, especially recurring crypto payments,  need to work through various complexities related to accepting payment on multiple networks, in multiple tokens, and from various types of wallets. 

A payment processor, like Loop Crypto, handles this complexity and provides a crypto payments API and tooling that are easy to use. This allows for the secure and quick transfer of funds from the customer’s wallet to the merchant’s wallet. 

What do crypto payment processors do?

Loop plays an important role in enabling businesses to accept and process various forms of crypto payment from customers. Some of the services Loop provides include transaction facilitation, authorization and authentication, encryption and security, settlement and funding, data reporting and analytics, and support for multiple currencies and payment methods. For example, a merchant may want to enable USDC payments from their customers. A crypto payment processor would offer the tooling required to facilitate that transaction at scale.

How does Loop work as a payment processor?

Loop works similarly to traditional payment processors making it easy for merchants to accept crypto payments from customers. To understand how Loop works, here is what a typical payment flow looks like:

  1. Customer initiates payment

When a customer makes a purchase, they sign a transaction from their wallet providing the business with authorization and approval to charge them for a specific token on a specific network. This authorization can occur using a Loop payment link, our pay component, or by sending a transaction directly on chain. The process of authorizing is the same regardless of what type of altcoin payment the customer is making.

  1. Transaction data 

Loop receives data about the payment transaction to be processed, such as the amount and the due date. Loop will use this information when initiating the payment on chain.

  1. Authorization check

Loop reviews the transaction details and checks if the customer has sufficient funds and approval available. It also confirms the authenticity of the transaction data, checking its signature against that of the merchant requesting payment.

  1. Transaction execution 

If the transaction is authorized and the payment is due, Loop sends an on-chain transaction, facilitating the payment from the customer’s wallet to the merchant’s wallet based on the details of the transaction data.

  1. Transaction completion

Once the transaction is processed on-chain, Loop notifies the merchant of the payment and the merchant delivers the goods or services to the customer.

  1. Settlement

If the merchant has elected to settle in crypto, the transaction is complete. If the merchant has elected to settle in fiat, transferring funds from the wallet to the merchant account may take a few days depending on the fiat currency and countries involved in a process known as “off-ramping.”

How to choose a crypto payment processor

Selecting the right crypto payment processor is crucial for businesses looking to accept crypto payments. Here are key factors to consider when evaluating a provider:

  1. Enhanced Customer Experience
    A seamless and reliable payment experience ensures customers can make payments anytime, anywhere, and from any device. A well-optimized processor enhances customer satisfaction and increases retention.


  2. Ease of Integration
    Look for a payment processor with an easy-to-embed widget or crypto payment API. Loop, for example, offers a fast and simple integration process, enabling businesses to start accepting crypto payments with minimal development effort.


  3. Settlement Options
    Flexibility in settlement is important. Some processors, like Loop, allow merchants to settle transactions in either crypto or fiat, providing options that align with business needs.


  4. Support for Multiple Networks and Tokens
    The ideal payment processor should support a wide range of networks and tokens. Loop enables payments across all EVM-compatible networks, including popular stablecoins like USDC payments, as well as alternative cryptocurrency payments.


  5. Pre-Authorization Capabilities
    Pre-auth functionality helps merchants verify a payment method before charging, reducing the likelihood of failed transactions and enhancing transaction reliability.


  6. Developer-Friendly SDK and API
    A strong software development kit (SDK) and API simplify the implementation of crypto payments, ensuring businesses can get up and running quickly. Loop provides an SDK designed to streamline the integration process for developers.


By evaluating these factors, businesses can select a crypto payment processor that meets their operational needs while ensuring a smooth and secure payment experience for their customers.
