security custody crypto bounty-program blockchain

BANKEX Custody Service is a world-class decentralized cryptocurrency depository for enterprises and individuals.
Our advanced features include multi-layer security, ease of access, flexible asset storage, and 24-hour customer service.

Every member of the BANKEX team knows that Custody Service security is unbreakable. But what about hackers?

If you find a bug or serious vulnerability in our Custody service, we are prepared to offer a reward of up to $15000.

How to Report a Bug or Security Vulnerability

All you have to do is create a text report on Google Docs or make a video report and upload it on YouTube (all reports must be private and available only by link).

Then send a link to [email protected].

How We Will Assess Your Reports

We will assess all reports with regard to bug severity, system criticality, and report quality. There will be 4 categories of bugs/vulnerabilities: critical, high, medium, low.

Critical severity ($10000 or $15000 if you accept payment in BKX)

  • Remote Code Execution
  • Ability to arbitrarily manipulate account balances
  • Withdrawing currencies from other accounts

High severity ($5000 or $7500 if you accept payment in BKX)

  • User Authentication bypasses
  • Privilege escalation allowing unauthorized access to sensitive data or funds

Medium severity($500 or $750 if you accept payment in BKX)

  • CSRF impacting non-critical settings
  • User de-anonymization

Low severity ($50 or $75 if you accept payment in BKX)

  • Leakage of lower sensitivity information such as name or email address
  • Potential phishing vector that Custody has the ability to mitigate

If a report is a duplicate, we won’t award a bounty. A report is a duplicate if we have another bug bounty report for the issue or if other security review processes have already identified the issue.

How long?

The program will run for 6 months: from October 15, 2018 to April 15, 2019.

If you have any questions, please contact us at [email protected].
