What does HashDit Snap not do?
Currently, HashDit Snap does not support screening during approval calls and signature requests due to the lack of support for these features in MetaMask Snap. However, once MetaMask Snap incorporates these capabilities, we have plans to introduce approval screening against blacklisted addresses and screening for signature requests. Stay tuned for future updates as we enhance the security features of HashDit Snap.
Can false positives happen?
While we aim for accurate risk assessments, false positives can occur. Exercise caution by verifying official URLs on platforms like CoinMarketCap, and confirming legitimacy through social channels. Be cautious of scams; seek multiple confirmations for added security. Your discretion is advised.
