Polygon is a family of Ethereum scaling solutions. The flagship Polygon PoS chain offers low fees and high throughput and has long been a top destination for DeFi, NFTs and stablecoin payments. Polygon has also shipped a zkEVM (a zero-knowledge rollup) and the AggLayer, which aims to unify liquidity across many chains.
Polygon has secured significant enterprise and consumer adoption — brands, payment companies and tokenized-asset issuers frequently choose it for its low costs and Ethereum compatibility. Its technology roadmap centers on zero-knowledge proofs and cross-chain aggregation.
The native token, POL (which migrated from MATIC), is used for gas and staking across the Polygon ecosystem and underpins the AggLayer's shared security model.
