Program rules


TomoChain looks forward to working with the security community to find security vulnerabilities in order to keep our businesses and customers safe.

Response Targets

TomoChain will make the best effort to meet the following response targets for hackers participating in our program:

  • Time to first response (from report submit) - 2 business days
  • Time to triage (from report submit) - 2 business days
  • Time to bounty (from triage) - 1 business days
  • We’ll try to keep you informed about our progress throughout the process.

Program Rules

  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for a reward.
  • Submit one vulnerability per a report, unless you need to chain vulnerabilities to provide impact.
  • When duplicates occur, we only award the first report that was received (provided that it can be fully reproduced).
  • Multiple vulnerabilities caused by one underlying issue will be awarded one bounty.
  • Social engineering (e.g. phishing, vishing, smishing) is prohibited.
  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with the explicit permission of the account holder.
