# Hiding Assets or Marking as Spam Your Definitive Vault operates entirely on-chain. This allows you to receive legitimate airdrops—but it also means you may occasionally receive unwanted or spam tokens. Most of these are automatically filtered using the **“Hide Dust & Spam”** feature. However, some airdrops may appear valuable at first due to artificially inflated prices caused by low or nonexistent liquidity. These may not be filtered automatically, but are easy to remove manually. To do this, click the three-dot menu next to the token and select **“Mark as Spam.”** This will remove the token from your interface and exclude its value from your portfolio.
