The linking wallet function of NFTScan browser is for signature verification only and never allow users to initiate any transactions, so there is no risk to funds. If you link a wallet and a pop-up window asks you to initiate a transaction, be sure to reject it! Because NFTScan browser will never let the user initiate a transaction, once a transaction pop-up appears, it means that a hacker has used some vulnerability to initiate a fraudulent request, so the user must reject it!
