About Company

Cybersecurity of the company and the security of our users' data is a top priority for us, therefore VeChain launched a bug bounty program to find vulnerabilities and pay rewards.

To participate in the contest, you must agree and follow the rules described in this policy. You must be the first to report a vulnerability to receive a reward.

You must send a clear textual description of the work done, along with steps to reproduce the vulnerability.

After sending report, you cannot tell anyone or anywhere. Public disclosure of a vulnerability makes it ineligible for a bounty. Also, please do not store screenshots and / or executable codes and scripts related to the vulnerability discovered on publicly available services and resources so that the information is not available to third parties.


This program includes ONLY resources that are listed below:

What to look for

Vulnerabilities are critical gaps and technical flaws in systems that can violate the integrity, availability or confidentiality of user’s information, as well as change access rights to it.

We are interested in next vulnerabilities:

  • Remote code execution and stored XSS
  • Database vulnerability, SQLi
  • Privilege escalation (both vertical and horizontal)
  • Data breach
  • Authentication bypass
  • CSRF
  • Obtaining sensitive information
  • Shell inclusion

The size of rewards

We appreciate your efforts in taking out time and pointing it out to us, it helps us be better in our approach. While we are very thankful for your efforts, we don’t want them to go unrewarded. Eligible bug rewarded based on the CVSSv3 severity and we set next payout range:

Severity (CVSSv3) | Reward
Critical | 3,000 USD
High | 1,800 USD
Medium | 700 USD
Low | 300 USD

*The rewards will be paid out in VET based on the current price.

However, it’s entirely at our discretion to decide whether a bug is significant enough to be eligible for reward. In special cases, the size of the award can be increased if the researchers demonstrate how the vulnerability can be used to inflict maximum harm.

The rules of bug bounty program

Automated scanners that generate massive network traffic volumes and may affect system performance are prohibited.

  • Localize all your tests to your account. Don't affect other users.
  • Findings derived primarily from social engineering (e.g. phishing, vishing, smishing) are not allowed.
  • In case you find chain vulnerabilities we pay only for vulnerability with the highest severity.
  • It’s forbidden to perform DoS / DDoS on resources in the Scope.
  • Follow disclosure guidelines.


In general, the following vulnerabilities do not correspond to the severity threshold: This section contains problems that are not accepted in this competition, because they are malicious and / or because they have a low impact on security.

  • UI and UX bugs and spelling or localization mistakes.
  • Descriptive error messages (e.g. Stack Traces, application or server errors)
  • Open redirects. 99% of open redirects have low security impact. For the rare cases where the impact is higher, e.g., stealing auth tokens, we do still want to hear about them
  • Publicly accessible login panels without proof of exploitation.
  • Reports that state that software is out of date/vulnerable without a proof of concept.
  • Host header issues without proof-of-concept demonstrating the vulnerability.
  • HTTP codes/pages or other HTTP non- codes/pages.
  • Fingerprinting/banner disclosure on common/public services.
  • Disclosure of known public files or directories, (e.g. robots.txt).
  • Clickjacking/Tapjacking and issues only exploitable through clickjacking/tapjacking.
  • CSRF in forms that are available to anonymous users (e.g. the contact form).
  • Login & Logout CSRF
  • Presence of application or web browser ‘autocomplete’ or ‘save password’ functionality.
  • Lack of Secure/HTTPOnly flags on non-security-sensitive Cookies.
  • OPTIONS HTTP method enabled
  • Lack of Security Speed bump when leaving the site.
  • Weak Captcha
  • Content injection issues.
  • HTTPS Mixed Content Scripts
  • Content Spoofing without embedded links/html
  • Self-XSS that cannot be used to exploit other users (this includes having a user paste JavaScript into the browser console).
  • Reflected File Download (RFD).
  • Best practices concerns.
  • Highly speculative reports about theoretical damage. Be concrete.
  • Missing HTTP security headers, specifically, For e.g.
  • Strict-Transport-Security

  • X-Frame-Options

  • X-XSS-Protection

  • Host Header

  • X-Content-Type-Options

  • Content-Security-Policy, X-Content-Security-Policy, X-WebKit-CSP

  • Content-Security-Policy-Report-Only

  • Infrastructure vulnerabilities, including:
  • Certificates/TLS/SSL related issues

  • DNS issues (i.e. mx records, SPF records, etc.)

  • Server configuration issues (i.e., open ports, TLS, etc.)

  • Outdated web browsers: vulnerabilities contingent upon outdated or unpatched browsers will not be honored, including Internet Explorer all versions
  • Vulnerabilities involving active content such as web browser add-ons
  • XSS issues that affect only outdated browsers (like Internet Explorer)
  • Issues that require physical access to a victim’s computer.
  • Physical or social engineering attempts (this includes phishing attacks against employees).
  • Recently disclosed 0day vulnerabilities.
  • Microsites with little to no user data
  • Most brute forcing issues
  • Denial of service
  • Spamming

In general, they do not correspond to the severity threshold for Android apps:

  • Sensitive data in URLs/request bodies when protected by TLS

  • Lack of obfuscation is out of scope

  • OAuth & App secret hard-coded/recoverable in APK

  • Crashes due to malformed Intents sent to exported Activity/Service/Broadcast Receiver (exploiting these for sensitive data leakage is commonly in scope)

  • Any kind of sensitive data stored in app private directory

  • Lack of binary protection control in android app

  • Runtime hacking exploits using tools like but not limited to Frida/ Appmon (exploits only possible in a jailbroken environment)

In general, they do not correspond to the severity threshold for iOS apps:

  • Lack of Exploit mitigations i.e., PIE, ARC, or Stack Canaries

  • Sensitive data in URLs/request bodies when protected by TLS

  • Path disclosure in the binary

  • User data stored unencrypted on the file system

  • Lack of obfuscation is out of scope

  • OAuth & app secret hard-coded/recoverable in IPA

  • Crashes due to malformed URL Schemes

  • Lack of binary protection (anti-debugging) controls

  • Snapshot/Pasteboard leakage

  • Runtime hacking exploits using tools like but not limited to Frida/ Appmon (exploits only possible in a jailbroken environment)
