How it works
In order to claim a bug bounty, you must:
- Discover an entirely unknown vulnerability.
- Alert us before posting the bug anywhere else – and give us sufficient time to patch the issue.
- Not use the exploit to steal money or data from CoinJar or its customers. If the exploit requires account access, you must use your own.
If you have any doubts or questions, email us at security@coinjar.com.
Ineligible bounties
We don’t reward bounties for any vulnerabilities not under our direct control. For example:
- Social engineering
- Issues requiring physical access to hardware
- Vulnerabilities in 3rd party software (Ruby, nginx, etc)
- Denial of Service
- Usability issues
