Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
The Phantom extension, Chrome or Brave profile, browser permission, privacy shield, cache state, mobile app, or network state is not aligned with the action being attempted
SOL, tokens, NFTs, or recent activity depend on selected address, hidden asset filters, app refresh, Solana RPC/indexing state, transaction status, and restore context
A restore can show a different address when the phrase, account order, browser profile, mobile backup, or device context differs
A token or NFT can be hidden by filters, stale app data, connected-app account context, or delayed Solana indexing even when the public address still has activity
Browser, extension, or mobile updates can reload Phantom, reset connected-app permissions, or leave stale Solana data until the app refreshes
A fake support page, cloned app, airdrop claim, direct message, or validation prompt is asking for recovery words, private keys, remote access, or an unsafe signature
