Polygon Bridge

Ethereum sidechain

## Overview Polygon Bridge is a cross-chain bridging solution that enables asset transfers between Ethereum and Polygon. Polygon operates as a sidechain (also referred to as a commit chain) that processes transactions separately from Ethereum's main network while anchoring security and finality to the Ethereum blockchain. The bridge exists to solve a core infrastructure problem: users and applications need a reliable mechanism to move tokens and liquidity between these two networks without significant friction. The bridge was built because Polygon's sidechain architecture requires a trustless
