Lighter knowledge base for agents (zkLighter and the robinhoodchain instance): the Python SDK signer, auth tokens, order ids and reflection lag, minimums, listings and write limits.
Lighter is a perp DEX built as a zk-rollup with two independent deployments: zkLighter mainnet and an instance on robinhoodchain, each with its own markets and accounts. Orders are signed with a non-EVM key through the official Python SDK, and the order list lags the rollup by a few seconds, so fills are confirmed from the position delta.
