Version
gill: v0.12.0
node: v24.9.0

The createSolanaClient function throws websocket failed to connect error when using txtx surfnet cloud rpc.

SolanaError: WebSocket failed to connect

  context: {
    __code: 8190004,
    errorEvent: ErrorEvent {
      Symbol(type): 'error',
      Symbol(kTarget): WebSocket {
        Symbol(kEvents): SafeMap(0) {},
        Symbol(events.maxEventTargetListeners): 10,
        Symbol(events.maxEventTargetListenersWarned): false,
        Symbol(kHandlers): SafeMap(0) {}
      },
      Symbol(kIsBeingDispatched): false
    }
  }

Steps to reproduce:

const { rpc, rpcSubscriptions, sendAndConfirmTransaction } = createSolanaClient(
  {
    urlOrMoniker: <use a surfnet rpc here>,
  }
);

@ZYJLiu Thank you for creating this issue.

1. Can you update the steps to reproduce to be more detailed to be able to reproduce this issue?
2. Are you sure this is an issue with Gill and not the rpc?

[ZYJLiu]

its not an issue with the txtx rpc, which works when using just Kit.

it seems the issue is here:
https://github.com/gillsdk/gill/blob/master/packages/gill/src/core/create-solana-client.ts#L63

the createSolanaClient function just replaces http with ws, but with txtx surfnet the websocket url starts with wss not ws

maybe add an optional param to define the websocket url separately from the rpc url

@ZYJLiu does surfpool use a http or https url at all? what is the regular rpc url you connect to (outside of websockets)
