Another huge milestone for @Agglayer. 

The v0.3 upgrade will make it possible for non-CDK chains to join Agglayer—beginning with Polygon PoS by end of Q3.

The new release enhances the security of the pessimistic proof by adding an additional safety guarantee. Before, the pessimistic proof verified only the balances of connected chains.

Now: it also verifies how blocks were built, using chain-specific execution proofs

For Agglayer to truly aggregate everything, core infra needs to be flexible and modular enough to be chain agnostic. Agglayer needs to provide the conditions required for safe, fast interop (sub XX seconds, to start).

Agglayer v0.3 is that first step.
