Add Conflux chain

[iosh]

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 (only if one doesn't already exist). For more information, please review the Ethereum JSON-RPC API docs. GitHub Link:

   • https://www.confluxdocs.com/docs/core/build/json-rpc/cfx-namespace

2. Write a CASA namespace spec if not already available for this namespace. GitHub Link: https://github.com/ChainAgnostic/namespaces/tree/main/conflux

3. namespaces: conflux

4. chains:

   
   # conflux mainnet
   conflux:cfx

conflux testnet

conflux:cfxtest

5. **RPC endpoints**

6. **[SLIP-0044](https://github.com/satoshilabs/slips/blob/master/slip-0044.md) coin type**:
   _\* slip44 coin type used in the namespace_
503

**Please note:**

**Registering a chain with the Explorer does not impact or improve the ability for wallets and dapps to support your chain.** It is simply a way for users to discover wallets and dapps that support your chain by:

- Browsing the [Chains List](https://docs.walletconnect.com/advanced/multichain/chain-list)
- Filtering results programmatically via the [Explorer API](https://docs.walletconnect.com/cloud/explorer)

**It is still up to wallets and dapps to provide concrete support for your chain once it is listed as part of the Explorer.**
