Overview
- Biconomy introduced ERC-8211, called smart batching, to let AI agents and smart wallets run complex DeFi actions in a single atomic call.
- The standard sets each input at execution time so later steps can use the real output from earlier calls instead of guessed numbers.
- Built-in predicates, including assertion-only checks, act as gates that halt the entire batch if a balance or condition is not met.
- It ships as a contract-layer encoding that works with today’s account-abstraction tools and can be built into TypeScript clients without a fork.
- Ethereum Foundation researcher Barnabé Monnot said the work fits the group’s Improve UX priority after a 2025 workshop with Biconomy.
