# Security Features

### 🔗 Link Protection

One of the many attack vectors in web3 are malicious links.  This may include wallet drainer signature requests, fake websites, fake airdrops, and the list goes on.  \
\
WalletChat utilizes the [WalletGuard](https://docs.walletguard.app/reference/scan) link protection API to block known malicious web3 scams.

This is a very useful service, but it can't detect issues which have just recently surfaced (zero-day vulnerabilities) so as always, we encourage users to be vigilant and when its too good to be true, it usually is a scam.  Moderators from many sites will not DM you first, and should never ask you for a seed phrase or private key.

### 🚫 Block Users

We all know the feeling of a scammer just not giving up in web3, and sometimes its easiest to block the user and move on.  WalletChat allows users to block another wallet address via the 🚫 icon within a DM.

### 🗑️ Delete Conversation

For purposes of inbox cleanup, we allow a conversation to be deleted (without blocking the user).  This  is available within a DM, simple click the trash bin and confirm the selection.  These messages are not recoverable after deletion, so please proceed with caution.

### &#x20;✅ Verified Moderators

Another feature alongside our Customer Support feature, is verified moderators for a given domain.  \
\
Currently these moderators are added/removed manually via direct communication with WalletChat, so please contact us directly for more info on setup.\
\
For moderators and users, they should see a verified blue check as shown in a DM discussion with a verified moderator:
