According to WuTalk, the NFT trading platform OpenSea has announced the launch of the Ethereum open standard ERC-8257, aimed at building an on-chain 'app store' infrastructure that integrates publishing, browsing, access control, and payments for AI agents (Agents). As an on-chain registry layer, ERC-8257 allows any tool developer to publish tools, define access rules, and set pricing. At the same time, it enables AI agents to autonomously browse the registry, meet relevant requirements (such as purchasing NFTs, minting subscriptions, signing payments, etc.), and acquire the tools they need without human intervention. https://www.(wublock123.com)/news/news-61722
