Potential Incorrect Information in Solana CAIP-10

[0xRAG]

Hello 👋

I'm bringing up what I believe is a discrepancy between Solana CAIP-2 and Solana CAIP-10. Specifically, the Chain IDs do not match up, and I believe CAIP-2 has the correct values and CAIP-10 does not.

According to the Chain ID Resolution Method in CAIP-2:

To resolve a blockchain reference for the Solana namespace, make a JSON-RPC request to the RPC Endpoints of a blockchain node with method getGenesisHash, for example:
// Request
{
"id": 1,
"jsonrpc": "2.0",
"method": "getGenesisHash"
}
// Response
{
"id": 1,
"jsonrpc": "2.0",
"result": "5eykt4UsFv8P8NJdTREpY1vzqKqZKvdpKuc147dw2N9d"
}

And in fact, executing this resolution method on the Solana Mainnet RPC endpoint:

curl https://api.mainnet-beta.solana.com -X POST -H "Content-Type: application/json" -d '
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getGenesisHash"
}
'

yields this result

{"jsonrpc":"2.0","result":"5eykt4UsFv8P8NJdTREpY1vzqKqZKvdpKuc147dw2N9d","id":1}

So the Chain ID for Solana Mainnet is 5eykt4UsFv8P8NJdTREpY1vzqKqZKvdpKuc147dw2N9d, as stated in CAIP-2, and the Chain ID stated in CAIP-10 is wrong. This is reproducible with the stated Chain ID for Solana Devnet.

Please let me know if I'm missing something, otherwise I'd be happy to open a Pull Request to correct this. Thanks!

Whoooops you are correct ser. I think the CAIP-10 examples were using the blockHash of block 0 rather than the genesis hash proper, i.e.

curl https://api.mainnet-beta.solana.com -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0","id":1,
    "method":"getBlock",
    "params": [
      0,
      {
        "encoding": "json",
        "maxSupportedTransactionVersion":0,
        "transactionDetails":"full",
        "rewards":false
      }
    ]
  }
'
