That structure lets an AI agent express flows like \u201cswap token A for token B on Uniswap, then deposit whatever actually arrives into Aave,\u201d with the second step pulling its amount from the resolved output of the first call rather than a guessed number.ethereum-magicians+3<\/p>\n<p>Smart batching also introduces assertion-only \u201cpredicate entries,\u201d where a batch step has no call target and instead encodes a boolean condition on chain state \u2014 for example, asserting that a wallet\u2019s WETH balance remains above a safety threshold after a leverage loop. These predicates use the same runtime resolution path as regular actions and act as gates between steps, turning a batch into what the spec calls \u201ca program with embedded safety checks, not a hopeful script.\u201d<\/p>\n<h1 class=\"wp-block-heading\" id=\"tying-into-ethereums-ux-and-agent-roadmap\">Tying into Ethereum\u2019s UX and agent roadmap<\/h1>\n<p>In comments to Decrypt, Ethereum Foundation research scientist Barnab\u00e9 Monnot said ERC-8211 fits directly into the organization\u2019s user-experience roadmap. \u201cThe protocol cluster of the Ethereum Foundation has \u2018Improve UX\u2019 as one of its strategic priorities,\u201d Monnot said, adding that \u201cERC-8211 support is coming from this strategic priority\u201d and that the collaboration with Biconomy began during a 2025 workshop convened by the Foundation\u2019s Improve UX initiative.<\/p>\n<p>Monnot argued that \u201cthe agentic execution angle is new, but has imposed itself given the rapid developments of agents over the last three months,\u201d calling ERC-8211 \u201ca perfect use case since agents can orchestrate complex cross-chain interactions, and ERC-8211 gives them the right platform to do so.\u201d Biconomy, which describes itself as \u201cthe smart wallet and execution engine for high-performance DeFi and autonomous onchain agents,\u201d has previously worked on account-abstraction tooling and gasless UX, and says ERC-8211 can be implemented directly in TypeScript clients that construct batches against its encoding.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p><\/div>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary Biconomy has proposed ERC-8211, a new Ethereum standard for \u201csmart batching\u201d complex DeFi flows.
