Infrastructure firm Biconomy has proposed a new technical standard for Ethereum called ERC-8211, designed to simplify complex decentralized finance transactions. The system allows multiple blockchain actions, like a token swap followed by a deposit, to execute fluidly in one transaction by resolving values in real-time. Researchers state it could significantly improve the user experience and is particularly suited for enabling autonomous AI agents to operate more efficiently on-chain.
A proposed Ethereum standard aims to simplify complex DeFi transactions by letting multiple blockchain actions execute in one step. The system, called smart batching, was introduced by Biconomy on Tuesday.
ERC-8211 addresses a common problem where the final output of a transaction, like a token swap amount, cannot be known in advance. “Developers have to either hard code that or find another way for that output to be used as an input for something else,” Biconomy co-founder Ahmed Al-Balaghi stated.
The standard allows each step in a transaction to reference the result of the previous one at execution time. This enables an agent to withdraw funds, swap the exact amount received, and deposit the result in a single signed transaction.
Al-Balaghi emphasized that ERC-8211 is not an Ethereum Improvement Proposal but a standard developers can implement directly. “ERCs exist because they don’t need a protocol change,” he explained.
Research scientist Barnabé Monnot, with the Ethereum Foundation, said the proposal aligns with the Foundation’s effort to improve blockchain usability. “The agentic execution angle is new, but has imposed itself given the rapid developments of agents,” Monnot said.
The collaboration began during a 2025 workshop organized by the Foundation’s Improve UX initiative. Al-Balaghi said the Foundation is now more willing to partner with the ecosystem to build technology quickly.
He noted the system runs on existing infrastructure without requiring a protocol change or hard fork. “That means you can create these really powerful flows without writing new smart contracts,” Al-Balaghi added.
