Tether Bug Bounty Rewards

Hunt, report, and get rewarded!

Tether believes that establishing relationships with security researchers and nurturing security research is a vital part of our mission to deliver the most advanced, security-enhanced, and trusted trading platform for digital tokens.

In collaboration with the cybersecurity and hacker development community, Tether runs this program to incentivise and reward the responsible disclosure of security vulnerabilities ("Responsible Disclosure"). Tether is always building and pushing out new code, so join our growing research community and help our developers to squash bugs with attractive rewards paid out to successful bugs discovered.
