Bug Bounty

Hunt down vulnerabilities for some cold hard JSE

Bug Bounty

JSE Security Bug Bounty

Happy bug hunting!

As part of our continued commitment to ensuring the safety and reliability of the JSEcoin system - we offer a bug bounty scheme for responsible disclosure of security vulnerabilities.

Software security researchers today are increasingly engaged with Internet companies to track issues and security vulnerabilities. Programs by HackerOne, Hacken, Google, Mozilla, and others have helped to create a strong bug-hunting community.

Our bounty program gives a tip of the hat to these researchers for their efforts and provides some cold hard JSE.

If you’ve found a vulnerability, submit it here .


Wow! Thanks for helping us out.

Rules for you

  • Don’t attempt to gain access to another user’s account or data.
  • Don’t perform any attack that could harm the reliability/integrity of our services or data. DDoS/spam attacks are not allowed.
  • Don’t publicly disclose a bug before it has been fixed.
  • Only test for vulnerabilities on sites you know to be operated by JSEcoin and listed under Open Bounties.
  • Don’t use scanners or automated tools to find vulnerabilities. They’re noisy and we may ban your IP address.

Rules for us

  • We will respond as quickly as possible to your submission.

    • Bugs related to browser extensions are also out of scope.
  • Bugs requiring exceedingly unlikely user interaction.
  • Insecure cookie settings for non-sensitive cookies.
  • Disclosure of public information and information that does not present significant risk.
  • Bugs that have already been submitted by another user, that we are already aware of, or that have been classified as ineligible.
