According to TechFlow, Polygon announced that its native token POL has been launched on the Ethereum mainnet.

Polygon said that POL is a next-generation token that can power a large ecosystem of ZK-based L2 chains. It does this through a native re-collateralization protocol that allows POL holders to verify multiple chains and perform multiple roles on each chain, turning POL into an efficient token.

Upgrading from MATIC to POL requires sending MATIC to the upgrade smart contract, which automatically returns an equal amount of POL.
