What is Polygon Mumbai?
The Polygon Mumbai Testnet is a test network created by the Polygon (previously Matic Network) team to provide developers with a sandbox environment to test their applications on the Polygon network. It is designed to be a replica of the Polygon mainnet, allowing developers to test and deploy their applications in a real-world-like environment before releasing them to the production network.
The Mumbai Testnet is an Ethereum-compatible test network that uses the Proof of Authority (PoA) consensus mechanism, which is fast and efficient for testing purposes. It also provides a number of developer-friendly tools and services, including a block explorer, RPC endpoints, and a faucet to obtain testnet tokens for testing purposes.
