Environment / auth

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
secret
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
secret
Read-only token for account observation without a signing key.
