Blockchain API Data Processing Agreement

Thank you for using the Blockchain API!

Blockchain API is an American company and our data infrastructure is based in the USA. Processing and storing data in a secure, fair, and transparent way is extremely important to us.

This Data Processing Agreement (“DPA”) is an addendum to the Terms of Service between Blockchain API and the customer.

If you are accepting this DPA on behalf of your customer, you warrant that: (a) you have full legal authority to bind your customer to this DPA; (b) you have read and understand this DPA; and (c) you agree, on behalf of your customer, to this DPA.

These service terms incorporate the Blockchain API Data Processing Agreement” (“DPA”), when the General Data Protection regulation (“GDPR”) applies to your use of Blockchain API services to process CryptoCheckout user data as defined in the DPA. We protect and secure your data to the high standards set out in the agreement.


  • “You” or “customer” refers to the company or organization that signs up to use the Blockchain API to interact with blockchains in any way.

  • In the course of providing the Blockchain API service to customer pursuant to the agreement, Blockchain API may process user data on behalf of customer.

  • In this Data Processing Agreement (“DPA”), “Data Protection Legislation” means the General Data Protection Regulation (Regulation (EU) 2016/279), and all other applicable laws relating to processing of visitor data and privacy that may exist in any relevant jurisdiction.

  • “data controller”, “data processor”, “data subject”, “personal data” and “processing” shall be interpreted in accordance with applicable Data Protection Legislation.

  • The parties agree that the customer is the data controller and that Blockchain API is its data processor in relation to data that is processed in the course of providing the service.

Privacy and security of your payees’ data

We take many measures to protect and secure your user data through backups, redundancies, and encryption. When you use our service to accept payment in crypto, Blockchain API will collect information about your payees.

You entrust us with this data and we take that trust to heart. You agree that Blockchain API may process your data as described in our data policy and for no other purpose. We do our best to deserve that trust by being open about who we are, how we work, and keeping an open door to your feedback.

You own all right, title, and interest to your data. We obtain no rights from you to your data. We do not collect and analyze personal information from users nor use these behavioral insights to sell advertisements. When using Blockchain API, you 100% own and control all of your data. We don’t sell or share your site data to any third-parties, and we don’t abuse your visitor’s privacy.

Even though the purpose of Blockchain API is to interact with the blockchain which creates a public record, we store as little - and often no - personal data or personally identifiable information (PII) as possible.

By using Blockchain API, all the payments that can be carried out anonymously are carried out as such. We minimize data collection in general. We measure only the most essential data points and nothing else.

We do not store, retrieve nor extract anything from visitor’s devices. The data we process cannot be used to identify any single individual, unless they explicitly provide that information to use.

Organizational and technical security measures

All of the data that we do track is kept fully secured, encrypted and hosted on our services in the US. Your visitor data never leaves the US and US-owned cloud infrastructure.

For encryption, we use https in transit and encryption at rest.

Processor’s obligations with respect to the controller

  • We do work with sub-processors. With each vendor, we assess their commitment to privacy.

Blockchain API shall notify the controller when modifying the list of subprocessors using our in-app notifications, email and/or blog. The controller is able to legitimately object and may terminate the agreement.

  • The only two cloud services we use as subcontractors that come in touch with your data are AWS and Stripe. All of your site data is securely stored in the US on US-owned server infrastructure and it never leaves the US. You can find the list of other cloud services and third party services that we use in our privacy policy.

  • If Blockchain API becomes aware of any accidental, unauthorized or unlawful security breach, destruction, loss, alteration, or disclosure of the personal data that is processed by Blockchain API in the course of providing the service, it shall without undue delay (not later than 48 hours after having become aware of it), notify customer by email and provide customer with a description of the incident as well as periodic updates to information about the incident, including its impact on customer content. Blockchain API shall additionally take action to investigate the incident and reasonably prevent or mitigate the effects of the incident.
