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
Polygon is a framework for creating Ethereum-compatible blockchain networks and scaling solutions. It aims to enrich the Ethereum ecosystem by providing tools to build scalable decentralized applications (DApps) and increase Ethereum’s transaction throughput with lower fees. Some popular Decentralized Finance (DeFi) platforms have already been deployed on Polygon, such as Aave, Curve, and SushiSwap.

To interact with DApps and tools on Polygon, you need to transfer your assets to the Polygon network. This is where the Polygon Bridge comes in. The Polygon Bridge is a trustless cross-chain transaction channel between Polygon and Ethereum. It allows users to transfer ERC tokens and non-fungible tokens (NFTs) to the Polygon sidechain, all through the use of smart contracts.
