How can I retrieve the default token symbol of an Ethereum network via json-rpc?

Ethereum would return "ETH"
Ethereum classic would return "ETC"

Use Web3's getChainId() to get the chain ID.

Then map the returned chain ID into the list of known networks from https://chainid.network/chains.json, where the currency symbol is in the nativeCurrency nested object.
