Sandeep AggLayer, the founder of Polygon, stated on the X platform that the new solution AggLayer for aggregation layer cannot be classified as L1 or L2. It is a "MetaLayer". "In my opinion, there will be two important "MetaLayers" on Ethereum, namely the feature layer and the aggregation layer, which cannot be classified as L1 or L2."

Blockchain interoperability project Union Labs plans to integrate with AggLayer. AggLayer is a decentralized service launched earlier this year by Polygon Labs, which allows for liquidity sharing between connected networks. Through this collaboration, both parties can deepen the connection between Polygon and the Cosmos ecosystem and its Inter-Blockchain Communication protocol (IBC).
