# ERC-8211 And ERC-7683 For Cross-Chain Execution

*ERC-8211 wraps multi-step workflows as a single signed batch; an embedded ERC-7683 order can outsource only the bridge leg to a solver.*

Former Ethereum Foundation researcher Barnabé Monnot [outlined](https://x.com/barnabemonnot/status/2057801212011921529) 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.

How The Two Standards Combine
-----------------------------

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.
