Chainfrog Oy (www.chainfrog.com) has developers available for blockchain projects. Founded in 2016, we have several blockchain references available. Product demos include: Chainfrog Data, Chainfrog IoT and Chainfrog Provenance. Chainfrog software assets dramatically speed up your project delivery time. Chainfrog Oy also supports https://multidasher.org/, which is a free open source project to manage Multichain blockchains using the power of Drupal 8.
