The KYC and Bank Account verification are done within a few minutes and give users a smooth onboarding experience. We provide users single-point access to a diverse suite of crypto-based financial products and services that are backed by security processes and insurance.

Program Rules

Testing Policy and Responsible Disclosure

Please adhere to the following rules while performing research on this program:

  • Denial of service (DoS) attacks on Coindcx applications, servers, networks or infrastructure are strictly forbidden.
  • Avoid tests that could cause degradation or interruption of our services.
  • Do not use automated scanners or tools that generate large amount of network traffic.
  • Do not leak, manipulate, or destroy any user data or files in any of our applications/servers.
  • Do not copy any files from our applications/servers and disclose them.
  • No vulnerability disclosure, full, partial or otherwise, is allowed.
  • Please avoid spamming support requests.

Reports of leaks and exposed credentials

In the context of this program, we do not intend to encourage, accept or reward reports of leaks that are not applicable to our program’s scope and identified outside of our program’s scope, such as:

  • Exposed credentials in/from an out-of-scope asset/source
  • Sensitive information exposed in/from an out-of-scope asset/source

Also, in order not to encourage dark and grey economies, in particular the purchase, resale and trade of identifiers or stolen information, as well as all types of dangerous behavior (e.g. social engineering, ...), we will not accept or reward any report based on information whose source is not the result of failure on the part of our organization or one of our employees/service providers.

This excludes, but is not limited to:

  • Stolen credentials gathered from unidentified sources (e.g. …)
  • Exposed credentials that are not applicable on the program’s scope
  • Exposed GitHub/GitLab (or similar) instance with no direct relation with our program’s scope
  • Exposed secrets (e.g. API tokens/keys or other technical credentials) that are not directly related to the program’s scope
  • Exposed PII on an out-of-scope asset

To summarize our policy, you may refer to this table :

Source of leak is in-scope Source of leak belongs to CoinDCX but is out-of-scope Source of leak does not belong to CoinDCX and is out-of-scope
Impact is in-scope (e.g. valid credentials on an in-scope asset) Eligible Eligible Not Eligible
Impact is out-of-scope (e.g. valid credentials for an out-of-scope asset) Eligible Not Eligible Not Eligible

Important precautions and limitations

As a complement to the Program’s rules and testing policy :

  • DO NOT alter compromised accounts by creating, deleting, removing or modifying any data
  • DO NOT use compromised accounts to search for post-auth vulnerabilities (they won’t be eligible anyway)
  • DO NOT include Personally Identifiable Information (PII) in your report and please REDACT/OBFUSCATE the PII that is part of your PoC (screenshot, server response, JSON file, etc.) as much as possible.
  • In case of exposed credentials or secrets, limit yourself to verifying the credentials validity
  • In case of sensitive information leak, DO NOT extract/copy every document or data that is exposed and limit yourself to describe and list what is exposed.
