Add Canton Network

[ganchoradkov]

Adding a new chain to the Explorer
To get a new chain added to the Explorer, you will need to submit the following:

1. JSON-RPC spec for Wallets
   GitHub Link: https://docs.walletconnect.network/wallet-sdk/chain-support/canton
2. Write a CASA namespace spec if not already available for this namespace.
   GitHub Link: n/a
3. namespaces: canton
4. chains:
   • canton:mainnet
   • canton:testnet
     although these are used only for the proposal, the actual chains are dependant on the validator used and are provided by the approving wallet
5. RPC endpoints: n/a
6. SLIP-0044 coin type: 6767

• I have read and understood the above clarification
