For more information about Polygon PoS please see their official documentation.
The Polygon PoS network is a hybrid Plasma Proof of Stake side-chain to Ethereum. It's fully compatible with the Ethereum virtual machine (EVM) which allows developers to leverage Infura, MetaMask, Truffle, and other tools they use for Ethereum when developing and deploying to the Polygon network.
Polygon's Bor node API is based on go-ethereum's JSON-RPC implementation. For usage examples, please see our Ethereum documentation.
You can also use WebSockets to call JSON-RPCs and create subscriptions. See
eth_subscribe for more information.
