Add Lamina1 chains

[BaltasarAroso]

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/lamina1/lamina1-integration

2. Write a CASA namespace spec if not already available for this namespace.
   GitHub Link: https://github.com/ChainAgnostic/namespaces/tree/main/eip155

3. namespaces:
   EIP-155 (EVM chain)

4. chains:

# lamina1 L1 mainnet
eip155:10849

# lamina1 ID mainnet
eip155:10850

#----#

# lamina1 L1 testnet
eip155:764984

# lamina1 ID testnet
eip155:767368

5. RPC endpoints

• Lamina1 L1 Mainnet: https://subnets.avax.network/lamina1/mainnet/rpc
• Lamina1 ID Mainnet: https://subnets.avax.network/lamina1id/mainnet/rpc
• Lamina1 L1 Testnet: https://subnets.avax.network/lamina1tes/testnet/rpc
• Lamina1 ID Testnet: https://subnets.avax.network/lamina1id/testnet/rpc

6. SLIP-0044 coin type:
   Avalanche C-Chain: 9005 (TBD)

• Source of namespace (if non-EIP155) chain information (particularly chainIds):
  ChainIds:
• L1 Mainnet: 10849
• ID Mainnet: 10850
• L1 Testnet: 764984

Additional context
Lamina1 Mainnets are EVM-compatible subnets on Avalanche, they are EIP-155 compliant. While they operate independently, they technically exist under the broader Avalanche namespace.

L1 Mainnet:

• Chain ID: 10849
• Subnet ID: 2hoHzxcZktxrTNoqCZhR9bEctc5oCuBqSp6SpRn6uvwxzLkvnD
• Blockchain ID (Base58): UhReZTXT8Cqsjat9ghRtCe5kBQPQexQB5zG5Fvf3egrdYfyoJ

Lamina1 Identity (ID) Mainnet:

• Chain ID: 10850
• Subnet ID: 2T4gpnissLkoezQ36XKxhrFAH5yynqKGa1u47XxCYTdfvePuNz
• Blockchain ID (Base58): hR6djBP7uMGJnXrjdUic2rzvvuuMpqMWNb5us7j8xgmj6Ck2N

L1 Testnet:

• Chain ID: 764984
• Subnet ID: 2ERCYPP3LWxzpb25jQAtR1FrXir8M723FKv76HNcixyYxHGuGu
• Blockchain ID (Base58): 2sNcXb5rmA1nCaabpoeVCvUHsCfLMMn3no1HjRy97BpHWiu3Kp

Lamina1 Identity (ID) Testnet:

• Chain ID: 767368
• Subnet ID: FxduCaHpKRwAWbkVxtfrW81NQBB66z55UpaY8SrJ84jqMgpeS
• Blockchain ID (Base58): 2bZPCoULmeotVbQHtEMqp13fxcrxQPkgfC6LhGm2sQWWV198Sp

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.

• I have read and understood the above clarification
