Former Ethereum Foundation researcher Barnabé Monnot outlined how ERC-8211 smart batching and ERC-7683 complement each other across the cross-chain execution stack. ERC-8211, introduced by Biconomy, lets users encode complex multi-step workflows as a single signed batch. ERC-7683 handles the solver side.

Combined, the two standards enable seamless intent-based bridging. ERC-7683 can encode a fronted liquidity request in a format any compliant solver can fill. ERC-8211 wraps a swap, bridge, and vault deposit into a vault sequence as a single signed batch; embedded inside is an ERC-7683 order for the bridge leg alone. The user signs once and outsources only what requires a solver.
