Here at Cornix, we understand that it takes a lot of trust to share sensitive information, like your API keys with an external service, and we don't take this responsibility lightly.
To ensure that you are always safe, we've spent a significant amount of time and effort making sure that all our users' information, especially sensitive ones like API keys, are stored safely in our system. To do that, we've consulted with security veterans to design our system in the safest way possible, and all user information is encrypted before it is stored.
As an added layer of protection, it is always recommended that all API keys you create don't have withdrawal permissions. This means that no one will ever be able to withdraw money from your account without your consent and your funds always stay safe in your exchange account.
