This standard defines a universal format for specifying network configurations i…n decentralized applications (dApps). The configuration includes essential information about Ethereum networks, such as:
* available RPC URLs
* native currencies
* contract addresses
* block explorers.
The goal of this standard is to simplify network configuration for dApp developers and enhance interoperability across Ethereum-compatible networks.
