Polygon blockchain development refers to building decentralized applications (dApps) and blockchain solutions on the Polygon network, a Layer 2 scaling solution for Ethereum. Polygon enhances Ethereum's scalability and transaction speed while maintaining decentralization and security. Developers use Polygon’s architecture to create dApps, DeFi platforms, NFT marketplaces, and more. The Polygon SDK allows for the creation of custom blockchains that are interoperable with Ethereum. Its low-cost, high-speed transactions have made Polygon a popular choice for businesses and developers looking to optimize their blockchain solutions for better performance and scalability.
