Ethereum Foundation researchers prioritize interoperability for Ethereum development. Near-term strategy focuses on intent-based architecture and message-passing infrastructure upgrades. The goal is to allow smooth execution of intents across layer-1 and rollups. Optimization metrics include time-to-inclusion, confirmation/finality, layer-2 settlement, and signatures per operation. Interoperability is crucial due to fragmentation in layer-2 protocols.

Development of interoperability work is divided into three streams: initialization, acceleration, and finalization. Projects include open intents framework, Ethereum interoperability layer, and interoperability standards. The open intents framework facilitates intent-based stack use in Ethereum development. The interoperability layer enables trustless cross-L2 execution. New standards ensure consistent crosschain user experience, defining interoperable addresses and standardizing asset consolidation.

The second stream focuses on speeding up processes at every layer, while the third stream focuses on finishing touches. Solutions are being explored to enhance zero-knowledge proof support and layer-1 finality times. Ethereum L2s aim to be interoperable within months.
