The address starting with "0xAf23" has been blacklisted by the PEPE contract deployer. This address has more than 25,000 100 million PEPEs are permanently locked, and the current value of these PEPEs is approximately US$8 million. According to on-chain data, the address purchased PEPE within a few hours after the Uniswap trading pair was launched, and was blacklisted by the PEPE deployer 8 minutes after the purchase. Apart from this no other addresses were blacklisted. Since ownership of the contract has been relinquished, the blacklist can never be modified. The contract has a destruction function but no further ability to mint coins. PEPE held by a blacklisted address may also be considered permanently locked.
