nteroperability: Polygon aims to achieve interoperability with the Ethereum Mainnet and other external blockchain networks. It enables seamless asset transfers between different chains by using protocols like the Plasma framework. This interoperability allows users to move assets and tokens between the Ethereum Mainnet and Polygon sidechains, enhancing liquidity and usability.

Bridge Mechanism: Polygon incorporates bridge mechanisms to establish connections between the Ethereum Mainnet and Polygon sidechains. These bridges enable the transfer of assets between the two networks, ensuring compatibility and accessibility. Bridges play a crucial role in maintaining the security and integrity of assets during transfers.
