As part of the expansion of Lykke Exchange, we are looking to add IOTA to our trading pairs. 

Our team has developed an abstract integration layer to be able to connect any blockchain to the Lykke Exchange. We need your help in building a standardized API on top of the IOTA blockchain node. 

The following features must be implemented: 

  • Generating simple transactions for making cashouts
  • Monitoring addresses and creating events when income transactions are detected
  • Private key and public address generation

A full list of API interface requirements are available at docs.google.com/…d3U/ 

Requirements specification 

  • Best practices should be used: comments, unit testing, etc.
  • Your implementation must be fully documented.
  • Submissions must be open source, with an appropriate license, and published on GitHub.

The following languages are accepted:

  • C#
  • JavaScript
  • Java
  • python
  • C / C++


The first-place contestant will receive an award of $3000, three runners-up will receive $1000 each.

Please refer to the Terms of Use of the organization and remuneration issues. If you have any questions, please feel free to ask them in the contest comments. 


Submitted results must be publicly available on the GitHub. There is no guarantee of winning a prize. The prizes are only awarded to entries that the Lykke judges find worthwhile. Prizes are awarded in Lykke coins, which may be redeemed for currency and sent to your bank. You must be at least 18 years of age. You must not submit twice — your first submission is the one that counts. You will be responsible for declaring your own income to your local tax authorities. All submissions will be disclosed to the public. The prizes are given at organizer’s sole discretion. The decisions of the judges will be final — there is no appeals process if your project does not win a prize. No other compensation will be given at this stage.
