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
