A group of Polygon founders and researchers previously proposed a token upgrade that would replace the network’s MATIC token with POL in a move that lets POL function as a single token for all Polygon-based networks.

These networks include the main Polygon blockchain, the Polygon zkEVM network, and various supernets – application-specific blockchains that run atop the main Polygon network.

The upgrade to POL from MATIC requires a simple technical action – sending MATIC to the upgrade smart contract, automatically returning the equivalent amount of POL.
