Polygon is a multi-dimensional DeFi underlying infrastructure that can conduct fully decentralized cross chain transactions and provide users with highly efficient and accurate prices for executable transactions. It also includes decentralized and stable digital currency, decentralized Oracle machine, decentralized insurance, liquidity mining, intelligent mining and other protocols, so as to create the most comprehensive decentralized financial platform, Any team who wants to join DeFi can use the corresponding smart contract protocol based on Polygon's underlying infrastructure to create their own products, without considering the underlying technical challenges, and easily complete product construction. Polygon will be combined with current mainstream public chains, such as Ethereum, EOS, Wave Field, etc., so that users can call Polygon's protocols on different underlying public chains to implement various DeFi function applications....
