ChainCatcher news, SocialFi "Debate to Earn Points" platform Socrates, made a significant iteration yesterday, transforming the existing ERC-1155 standard SBT pen into the ERC-721 standard Pioneer pen, welcoming unique and tradable NFTs, and opening up a trading market within the app. On the first day of the Pioneer pen launch, it surpassed a trading volume of 200,000 USDT. Currently, the minimum price for a Level 1 pen is 14 USDT, the minimum price for a Level 2 pen has reached 258.88 USDT, and the minimum price for a Level 3 pen has risen to 398 USDT.The launch of the Pioneer pen is part of Socrates' strategy, which aims to create a comprehensive 360° instant rewards ecosystem that encourages users to actively participate through interactions on various platforms and incentivizes users to engage in the ongoing SOC token airdrop competition. At the same time, Socrates has also introduced a new feature called Pop Quiz. Users can interact with questions from other users within 30 minutes, and the correct answers (determined by the questioner) will be revealed immediately. If the vote is correct, participants can win prizes instantly, and the question will close; however, if the vote is incorrect, the questioner will receive the participants' points.

ChainCatcher message, Delegate founder foobar stated on platform X that it is quite certain that over $100 million has been stolen because ERC-721 named its interface function safeTransferFrom() instead of transferFromWithCallback(). This may be the most disastrous variable naming decision in history.

ChainCatcher news, MetaMask announced that in the latest version of the extension, all ERC-721 and ERC-1155 tokens will appear as long as automatic NFT detection is enabled. With this update, users can send ERC-721 tokens, and the ability to send ERC-1155 tokens will be added soon. (source link)

Chain Catcher news, Stanford University researcher kaili.eth tweeted that he has collaborated with several other researchers to design two new Ethereum token standards: ERC-20R and ERC-721R.kaili.eth explained that the design of ERC-20R and ERC-721R aims to address the rampant theft incidents in the cryptocurrency industry, with the highlight being "reversible transactions." Specifically, ERC-20R and ERC-721R introduce a "decentralized court" mechanism, where in the event of asset theft, victims can first apply to freeze the assets. At this point, the "decentralized court" can decide whether to agree to the freeze through a quick round of voting. For the frozen assets, the "court" will subsequently determine whether to unfreeze or return the assets based on the evidence provided by both parties involved, thereby resolving security incident disputes.
