Gatecoin Bug Bounty Program

Responsible Disclosure

Security of user funds, data and communication is of utmost importance to Gatecoin. In pursuit of the best possible security for our service, we welcome responsible disclosure of any vulnerability you may find in Gatecoin. In order to encourage responsible disclosure, we will not pursue legal action against researchers who point out a problem provided they do follow principles of responsible disclosure which include, but are not limited to:

  • Only access, expose, or modify your own customer data. Do not perform any attack that could harm the reliability or integrity of our services or data.
  • Avoid scanning techniques that are likely to cause degradation of service to other customers. (DoS, Spamming)
  • Keep within the guidelines of our Terms of Service.
  • Always keep details of vulnerabilities secret until Gatecoin has been notified and had a reasonable amount of time to fix the issue.

We may suspend your account and ban your IP if you do not respect these principles.

In order to be eligible for a bounty, your submission must be accepted as valid by Gatecoin. We use the following guidelines to determine the validity of requests and the reward compensation offered.

Our engineers must be able to reproduce the security flaw from your report. Reports that are too vague or unclear are not eligible for a reward. Reports that include clearly written explanations and working code are more likely to garner rewards.


More severe bugs will be met with greater rewards. Any bug which has the potential for financial loss or data breach is of sufficient severity.

In general, vulnerabilities that may lead to lower rewards are those that do not cause one or several of the following results:

  • Partial/complete loss of funds
  • User information leak
  • Severe performance impact (other than DoS)
  • Loss of accuracy of exchange data

Some Examples of Qualifying Vulnerabilities

Gatecoin reserves the right to decide if the minimum severity qualification threshold is met and whether it was already reported.

  • Authentication bypass or privilege escalation
  • Clickjacking leading to vulnerabilities in scope of the severities awarded
  • Cross-site scripting (XSS)
  • Cross-site request forgery (CSRF/XSRF)
  • Mixed-content scripts
  • Server-side code execution
  • User data breach

Some Examples of Non-Qualifying Vulnerabilities

Reporting the following vulnerabilities is appreciated but will not lead to systematic reward from Gatecoin.

  • Denial of Service vulnerabilities (DoS)
  • Email spoofing (SPF / DMARC / DKIM)
  • Possibilities to send malicious links to yourself or people you know
  • Security bugs in third-party websites that integrate with Gatecoin API
  • Vulnerabilities related to 3rd-party software (e.g. Java, plugins, extensions) or website unless they lead to vulnerability on Gatecoin website
  • Spamming
  • Usability issues, forms autocomplete
  • Insecure settings in non-sensitive cookies
  • Browser Cache vulnerabilities
  • Vulnerabilities (including XSS) that require a potential victim to install non-standard software or otherwise take very unlikely active steps to make themselves be susceptible
  • Non-technical attacks such as social engineering, phishing, or physical attacks against our employees, users, or infrastructure
  • Vulnerabilities (including XSS) that affect only legacy browser/plugins
  • Disclaimer: the Blog is currently out of scope for the Bug Bounty


  • Only one bounty will be awarded per vulnerability.
  • If we receive multiple reports for the same vulnerability, only the person offering the first clear report will receive a reward.
  • We maintain flexibility with our reward system, and have no minimum/maximum amount; rewards are based on severity, impact, and report quality.

To receive a reward, you must reside in a country not on international sanctions lists. This is a discretionary program and Gatecoin reserves the right to cancel the program and/or decide if the minimum severity threshold is reached and if it was previously reported.
