Why is there no RPC endpoint for Lighter?
Because there is nothing to talk to. Lighter is an application-specific zk rollup: its circuits prove order matching and liquidations, and it runs no general-purpose virtual machine. There are no smart contracts, so no JSON-RPC exists on any provider. The exchange surface is the interface.
What can I subscribe to?
Order-book state per market as snapshots plus deltas, trade prints as they are matched, and account-level updates covering positions, funding and liquidations. One connection carries many market subscriptions.
Should I use the stream or the indexer?
The stream for what is happening now, the indexer for what already happened. A WebSocket cannot answer a question about last month, and a warehouse cannot tell you about a fill from a second ago. Most trading setups run both.
How is Lighter streaming priced and provisioned?
It is not on sale yet - the Lighter order-book stream is in build. Tell us on Telegram which markets you need and how many connections, and we come back to you first when it opens. Billing, when it opens, is the same as everything else here: crypto-only, monthly and prepaid.
