Optional settings from the registry entry, left out of the block above: LIGHTER_NETWORK (Deployment to read: mainnet, testnet, or robinhood. Defaults to mainnet), LIGHTER_ACCOUNT_INDEX (Sub-account the agent trades from. Read-only tools work without it), LIGHTER_API_KEY_INDEX (API key slot bound to the sub-account, 0 to 254), LIGHTER_API_KEY_PRIVATE_KEY (API key private key. Full write authority over the account it is bound to, so use a dedicated sub-account), LIGHTER_MAX_NOTIONAL_USD (Per-order notional ceiling in USD. Required before any order can be signed), LIGHTER_CHAIN_ID (Layer-2 chain id bound into every signature. Mainnet uses 304 and testnet 300, so this is only needed on a deployment that publishes none), LIGHTER_READ_ONLY_TOKEN (Read-only token for account observation without a signing key).
