On May 27, 2026, OpenSea announced the launch of the Ethereum standard ERC-8257 as the "AI agent app store." The standard enables developers to register tools on-chain, define access rules and pricing, and allows AI agents to autonomously discover and utilize these tools. It integrates with ERC-8004, MCP, and x402 to support AI agent operations on Ethereum. OpenSea is inviting developer feedback to refine the draft. This update brings new AI and crypto developments and underscores recent Ethereum advancements.

BlockBeats report, on May 27, OpenSea announced the launch of the Ethereum open standard ERC-8257 (Agent Tool Registry), positioning it as an "app store for AI agent tools," enabling developers to register tools on-chain, declare access rules and pricing, and allowing AI agents to autonomously discover, purchase access, and invoke tools without human intervention.


OpenSea states that this standard is designed to be layered with protocols such as ERC-8004 (Proxy Identity), MCP (Tool Discovery), and x402 (Payment Protocol) to form the infrastructure for on-chain AI agent operations. ERC-8257 is currently in draft form, and OpenSea invites developers to contribute to refining the specification.
