FAQ

Is Polygon an ERC-20 token?

No, Polygon is not an ERC-20 token. It is a layer 2 scaling solution for Ethereum. Its native token is MATIC, which operates on the Polygon network to facilitate transactions and network operations.

Can MetaMask hold a Polygon?

Yes, MetaMask can hold Polygon tokens. Add the Polygon network to MetaMask manually, then you can store and manage MATIC and other Polygon-based tokens directly in your wallet.

Which network does Polygon use?

Polygon uses the Ethereum blockchain network. It is a multi-chain system designed to be compatible with Ethereum, providing scaling solutions and enhanced interoperability for decentralized applications.
