Add Alephium

[nop33]

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://github.com/alephium/alephium/blob/master/api/src/main/resources/openapi.json
   • https://github.com/alephium/explorer-backend/blob/master/app/src/main/resources/explorer-backend-openapi.json
2. Write a CASA namespace spec if not already available for this namespace. GitHub Link: https://github.com/ChainAgnostic/namespaces/tree/main/alephium
3. namespaces: alephium

4. chains: Alephium's chain id follows this format alephium + ":" + group + "_" + network_id where group can be 1, 2, 3 or 4 which represent individual group, or -1 which represent all groups. The value of network_id could be mainnet, testnet or devnet. See CAIP2 for more info. Here are a few examples of chain ids:

     # Alephium mainnet, group 0
     alephium:0_mainnet
   
     # Alephium testnet, any group
     alephium:-1_testnet

5. RPC endpoints
   • https://docs.alephium.org/infrastructure/public-services
6. SLIP-0044 coin type: 1234

References To ensure timely processing of your request, please provide the following references:

• [x] Source of RPC endpoints (e.g. RPC docs):

  • Full node: https://node.mainnet.alephium.org/docs/

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
• Filtering results programmatically via the Explorer API

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

CR-506 Add Alephium

[nop33]

Hi @Cali93! Thank you for looking into this issue!

When browsing the Chains List I see that only the 2 examples that we gave above are included:

This is not an exhaustive list, as described by the issue description as well as CAIP2:

That means the full list is:

alephium:0_mainnet
alephium:1_mainnet
alephium:2_mainnet
alephium:3_mainnet
alephium:-1_mainnet
alephium:0_testnet
alephium:1_testnet
alephium:2_testnet
alephium:3_testnet
alephium:-1_testnet
alephium:universal

The list extends with devnet as an option, but I believe you are not interested in it:

alephium:0_devnet
alephium:1_devnet
alephium:2_devnet
alephium:3_devnet
alephium:-1_devnet
