Responsible Disclosure Policy

Important note: for any immediate security report please proceed to our report page.

The security of the MultiversX blockchain, and associated core components, is a top priority for MultiversX. Our Proof of Stake network is secured by considerable amounts of EGLD and provides valuable services for business or private use. Our mission is to become a layer of trust for digital financial systems at internet scale, and the highest level of security is a mandatory prerequisite.

The security researcher community regularly makes valuable contributions to the security of organizations and the broader Internet, and MultiversX recognizes that fostering a close relationship with the community will help improve the security of the MultiversX blockchain. So if you have information about a vulnerability in the MultiversX blockchain and associated components, we want to hear from you.

Reporting a Security Issue

Please DO send an email to security[@]multiversx[.]com

Please DO NOT open public issues on Github that contain information about a potential security vulnerability as this makes it difficult to reduce the impact of valid security issues.

What to include:

  • Well-written reports in English will have a higher chance of being accepted
  • Reports that include proof of concept code will be more likely to be accepted
  • Reports that include only crash dumps or other automated tool output will most likely not be accepted
  • Reports that include products & services that are out of scope (see the Scope section below) will not be considered
  • Include how you found the bug, the impact, and any potential remediation
  • Any plans for public disclosure

What you can expect from us:

  • A timely response to your email (within 2 business days).
  • An open dialog to discuss issues.
  • Credit after the vulnerability has been validated and fixed.

Coordinated Responsible Disclosure Policy

We ask security researchers to keep vulnerabilities and communications around vulnerability submissions private and confidential until a patch is developed to protect the MultiversX blockchain and its users.

Please do:

  • Allow the MultiversX team a reasonable amount of time address security vulnerabilities
  • Avoid exploiting any vulnerabilities that you discover
  • Demonstrate good faith by not disrupting or degrading MultiversX services, products & data

MultiversX pledges not to initiate legal action against researchers as long as they adhere to this policy.
