BullPay works with a wide variety of customers. Learn more about how we support DApps, wallets, payment and trading platforms, data aggregators, and other blockchain companies.

Our team works to remove the barriers to blockchain interaction, help more business get started, expediate growth for existing companies, and increase the GDP of the blockchain economy.

Our mission is to provide
 quick and easy access to blockchain data.

Data lies at the heart of any significant application. That is why everything we do is focused on removing barriers to the blockchain communication. Every aspect of our API offering is designed to empower developers; they can build more and faster by using trusted tools that provide the functionality that they require at minimal cost.


BullPay focuses on what customers want, and then deliver it. We make the customer to be the centerpiece of all our efforts. For example, the chief complaint from our customers is that they can’t scale using our competitors, so we make it easy for apps to scale. Not just in terms of ensuring user growth – but also in terms of adding new blockchains.


BullPay is a company built on trust and security. Trust and integrity are our core principles – see our patch notes for example. All of our products are built with as many OWASP ASVS Level 3 best practices as possible.


Developers are critical to app success. With BullPay, there is no need to learn about server configuration, node configuration, network management, database tuning, or updating all the previous items on a regular basis. BullPay removes obstacles so developers can stay focused and produce their best work.

Our history

BullPay is probably the biggest underdog you never heard of in the blockchain Industry. On paper, we should not have a right to compete with the industry giants. While they use existing database tech, like SQL, NoSQL, MongoDB, etc. to index data (which leads to reduced historical capabilities and/or response times), we built our memory-mapped database technology from the ground up. We have also become highly skilled at running scalable, reliable and cost effective infrastructure out of necessity. Combining our incredibly efficient but powerful technology and infrastructure results in low prices for our customers, setting the stage for the phenomenal growth to follow.
