description Polygon PoS Overview

While often categorized as a sidechain or L2, Polygon PoS functions as a high-performance Layer 1 that is deeply integrated with the Ethereum ecosystem. It provides a low-cost, scalable environment for dApps while maintaining EVM compatibility.

Polygon has massive adoption among brands and gaming companies due to its ease of integration and established infrastructure. It serves as an excellent entry point for developers who want to stay within the Ethereum security umbrella but need lower fees.

help Polygon PoS FAQ

Is Polygon PoS a true Ethereum Layer 2?

Polygon PoS has its own validator set and is commonly described technically as an EVM-compatible sidechain rather than a rollup that inherits Ethereum's full security. It periodically submits checkpoints to Ethereum, but that does not give it the same trust model as Arbitrum or Optimism.

Does Polygon PoS use MATIC or POL for gas?

POL replaced MATIC as the native gas and staking token on Polygon PoS in September 2024. MATIC held on Ethereum may require migration through the official Polygon process, while the change on Polygon PoS was handled at the network level.

Can Ethereum smart contracts run on Polygon PoS?

Usually, because Polygon PoS is compatible with the Ethereum Virtual Machine and supports familiar Solidity tooling. Developers still need Polygon-specific RPC endpoints, deployed contract addresses, gas in POL, and careful handling of bridges.

How do assets move between Ethereum and Polygon PoS?

Users deposit through a bridge contract on Ethereum and receive the corresponding representation on Polygon PoS. Returning assets requires the bridge's withdrawal process, so users should verify the official contract, token mapping, fees, and expected finalization time.
