CDK repositories

You want to know what source repositories Lumia's chain is actually built from, and which parts are Lumia-specific versus stock Polygon CDK.

Who this is for: developers or infrastructure engineers who need to read, audit, or build against the underlying stack rather than just use the public RPC. Prerequisites: Lumia's chain framework and settlement (concept: read this first for what CDK and AggLayer are on Lumia). Time: reference lookup, not a task with a fixed duration.

Architecture

Lumia Prism, the name /reference/contract-addresses uses for Lumia's mainnet, is built on Polygon CDK as a zkEVM validium-model L2, settling through Polygon's shared AggLayer (see /lumia/architecture/polygon and /lumia/architecture/polygon/agglayer). Polygon CDK's core repositories are public open-source infrastructure maintained by Polygon, not Lumia-specific.

In the meantime

For the settlement-layer contract addresses that are confirmed (not source repos, but on-chain addresses), see /reference/contract-addresses. For what CDK and AggLayer give Lumia conceptually, see /lumia/architecture/polygon.
