How to Use the Polygon Bridge?
The Polygon Bridge allows users to quickly transfer ERC tokens and NFTs to the Polygon sidechain. There are primarily two bridges on Polygon, the Proof of Stake (PoS) Bridge and the Plasma Bridge. Both can bridge assets from Ethereum to Polygon (and vice versa), but they adopt different security methods. The PoS Bridge uses the Proof of Stake (PoS) consensus algorithm to secure its network. It supports the transfer of Ether (ETH) and most ERC tokens. It’s the recommended option for most users. The Plasma Bridge is for devs that need increased security. It uses the Ethereum Plasma scaling solution and supports the transfer of MATIC, ETH, ERC-20, and ERC-721 tokens.

About Lesson

With the number of blockchains rising in the crypto space, sharing data and tokens between different networks has been challenging. Some projects are tackling this problem by building bridges between networks to facilitate asset transfers.

The Polygon Bridge is designed to increase interoperability between the Polygon and Ethereum blockchains. With a compatible cryptocurrency wallet, users can easily transfer tokens back and forth.
