Best Crypto APIs for Developers


Bitcoin recently marked its 10th anniversary on January 3, 2019, a full decade since the genesis block was mined by Satoshi Nakamoto back in 2009. The beginning years of Bitcoin history flew under the radar for most people, aside from the most passionate individuals in the crypto community.

While infrastructure development was slow to start, the bull run of 2017 brought a new wave of products onto the crypto scene. Today, development in crypto is at an all-time high, with new developers flocking from other industries in search of a “crypto gold rush”.

Whether you’re a cryptocurrency developer, trader, or just passionate about all things crypto, there are APIs available that are designed to make your crypto journey smoother. Whether you want to develop a personal trading bot, a payments application, or business settlement solution, there are APIs that can help you get started.

Development teams are often stretched thin due to limited resources and tight schedules. This challenge becomes further magnified when it comes to developing crypto apps, which currently lacks tools for scaling operations. For independent and 3rd-party app developers, maintaining a working business product is extremely costly.
