Address poisoning aims to make you choose a wrong recipient from familiar-looking history. You can copy the displayed text perfectly and still send to someone else. Verify who the address belongs to, rather than treating matching end characters or a recent activity entry as authentication.
An unfamiliar token appearing at your address does not prove you received a saleable reward, and its arrival alone does not prove someone obtained your keys. Investigate through public data without turning curiosity into an unexplained signature, payment or disclosure of recovery secrets.
The same 0x address appearing on two networks does not make their balances one account ledger. The address is part of the destination instruction; the network determines where the transaction executes. Check the complete receiving route before selecting a cheaper or more familiar withdrawal option.
An RPC endpoint is a connection a wallet uses to request network information and submit supported requests. Adding one does not transfer assets or certify the network. Verify its source, network identity and data limitations before relying on a familiar-looking entry in the wallet menu.
