Korean crypto trading platform Upbit has released MetaMask signature request "anti-phishing precautions". Specifically: when a user registers a personal wallet in Upbit, a MetaMask signature will be requested to verify that the wallet is owned by the user; if the address requested for the signature on the original item is not Upbit, please cancel the signature; if a warning message in red text appears at the top of the message page, please cancel the signature; if the message item displays a hash value starting with 0x instead of the signature requested by Upbit, please cancel the signature.
