SECURITY

The Security team protects our network, partners and data. We work to ensure
that our software, systems, and smart contracts are secure.




We believe that security is not a one-time activity, but a continuous process
that requires constant monitoring and improvement. We conduct regular security
audits to identify any potential vulnerabilities and take the necessary steps to
address them. We continue to invest in the best technologies and security
practices to ensure the safety of our network. If you believe that you have
discovered a security or privacy vulnerability in one of our systems or
products, please report it to us through our official bug bounty programs on
HackerOne or Immunefi.




We only accept vulnerabilities and bugs submitted through these channels to
ensure proper tracking, triaging, and bounty reward purposes and therefore do
not accept direct reports. However, if you need to contact our team for any
other reason please use the provided PGP key below.




Our PGP key can be downloaded here.
