Biconomy, in collaboration with the Ethereum Foundation, has introduced ERC-8211 to address limitations in current smart contract execution, aiming to enhance the dynamic execution capabilities for AI agents in DeFi. This new standard, unveiled in April 2026, seeks to overcome the static nature of existing execution models by allowing parameters to be dynamically evaluated at runtime, thus enabling more complex and secure DeFi workflows. ERC-8211 transforms batch processing from a sequence of transactions into a program with embedded security checks, using three composable primitives: Fetchers, Constraints, and Predicates. This allows AI agents to execute multi-step DeFi strategies in a single transaction, dynamically resolving values and ensuring conditions are met before proceeding. The standard is fully compatible with account abstraction frameworks, enhancing the role of smart wallets in managing complex on-chain operations.
