Bug Bounty Program

November 25, 2020

The purpose of this Bug Bounty program is to stimulate the finding of software vulnerabilities on EXMO in order to make it as secure as possible. External valuations of security are as important as internal testing and revisions of applicable systems. We appreciate your interest in this program, and we see constant improvement of EXMO security systems as a team effort that also involves our proactive users. Together we are making the safety of EXMO services even better.

We encourage our users and external researchers to conduct testing of our systems using their own tools.

Rules for research

Below are the rules for you to follow for responsible bug research and to make an appropriate bug report:

  • do not intentionally access non-public EXMO data any more than is necessary to demonstrate the bug;
  • do not permanently delete or modify EXMO hosted data;
  • do not disrupt our internal or external services;
  • do not violate the privacy of EXMO users;
  • you can only target your own account in the process of bug research;
  • do not share EXMO confidential information;
  • do not employ social engineering malicious activities;
  • do not use any brute-force techniques in order to gain access to the system;

Submit a bug

Please, submit your bug reports to support@exmo.com. Our technical team shall reach you shortly if the bug in question is recognised by them as such. Include as much information as possible to your message, so that we can perform an in-depth review of the bug, asses it and consider its potential impact. Also, please include to your bug message an instruction and/or proof-of-concept codes to replicate your found bug.

If you want your name to be included in the Wall of Fame, then include it to your bug report message.

Get a reward

The minimum reward for the reported and confirmed bug is 100 USD (One Hundred US Dollars). If we consider that the reported bug is of moderate or critical technical severity – we will pay you more.

Payment of one reward is made per one bug.
