Add SKALE Network Chains (EVM Compatible)

[TheGreatAxios]

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. Link: https://docs.skale.network/technology/json-rpc-interface
2. Write a CASA namespace spec if not already available for this namespace. eip155
3. namespaces: *known chain namespaces (e.g. eip:155 for Ethereum/EVM-based chains, solana, ...) eip:155
4. chains: *known chains, where the primary key is a compound key composed of namespace + reference (e.g. ETH mainnet is eip155:1). _Please provide labels for each chain (e.g. mainnet, testnet, devnet, ...)

6. SLIP-0044 coin type: 60

Additional context Add any other context here.

@TheGreatAxios we're missing the SLIP-0044 coin type here, could you please specify (e.g. by default 60 for ETH) and we can then add the SKALE chains to be selectable for submissions in our Cloud/Explorer.

[TheGreatAxios]

Hey @bkrem

Thanks for your response. I did some research into this and was a bit unsure. The chains are fully EVM compatible and support ERC-20 etc like ETH, however, the chains don't use ETH for gas, but sFUEL which is a value-less token.

Is the SLIP value then 60 since it's compatible with Ethereum in that way? Or do different SLIPs need to be calculated? If so, can you provide guidance here as I went through all the docs but there is limited information on calculating slips coin ids.

Thank you!

Thanks for following up here @TheGreatAxios.

I think 60 ETH is a sensible default if sFUEL doesn't have its own SLIP-044 value 👍

FYI we batch process these requests every Friday so this one will be included for this Friday's round.

[TheGreatAxios]

Thank you!

Hey @bkrem

Checking in to see when this will be added as it was not done this past Friday - thanks!

[bkrem]

@TheGreatAxios indeed, apologies for the wait. Cloud team got busy with other priorities end of last week.

Change is rolled out on staging. Will go live on https://cloud.walletconnect.com EU morning tomorrow

[TheGreatAxios]

Thank you and no worries - we are excited to have this available on SKALE!
