PIP-18: Polygon 2.0 Phase 0
PIP-18 specifies Phase 0 of Polygon 2.0 and provides a high-level outline for the upgrades that will be detailed in separate PIPs. Phase 0 milestones are specifically designed to ensure that no action will be required from end users and developers already on Polygon PoS and Polygon zkEVM chains. Several changes will be implemented on the Ethereum contracts for these chains:
The initiation of the upgrade from MATIC to POL;
The upgrade from MATIC to POL as the native (gas) token for Polygon PoS;
The upgrade from MATIC to POL as the staking token for Polygon PoS;
The launch of the Staking Layer and migration of Polygon public chains to leverage it.
Not all of the upgrades will happen at once. The image below details important milestones.
