My friend bought a token which is called PI token, which seems relate to leash or shiba inu tokens.
He cannot sell it in uniswap, the wallet confirmation page doesn't pop up. And he cannot even transfer the tokens. the contract is 0xb7274fa626ed09cac2bdfbb8a4dec99080b28663.
transfer method looks normal thought they have a if about tokenRecipient.
I cannot find any info about whitelist or something else.
