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.
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.
