The security of your Kukai wallet is of utmost importance, and we take all necessary steps to ensure it is not compromised. Tokens are one way of verifying your identity and authorizing access to your wallet, but they cannot be used to compromise it. We have implemented measures such as sanitizing content like SVG scripts to ensure that malicious code does not enter your wallet. If you have received a strange token, it is important to check its source and make sure it has not been tampered with. If you are concerned about the security of your wallet, we recommend that you contact Kukai's customer service team for further advice and assistance.
