FAQ
Get In TouchDo you take deposits?
No. Your cash and contracts stay at Kalshi or Polymarket. Molecule only sends the orders.
How is this different from the venue?
The venue is still the exchange. Molecule is the desk in front of both: one login, one book, one way to send an order.
What do I sign, and what do you store?
Trading calls are Ed25519. You keep the private key; we store the public key only. Venue API secrets (Kalshi PEM, Polymarket L2) are encrypted at rest. Human sessions use a JWT for org and key management — not for placing orders.
Can one order hit multiple venues?
Yes, when the listings share a generic_asset_id. DIRECT sends to one instrument_id. BEST_PRICE picks the cheapest member after fees. SPLIT walks the aggregated book and slices size across venues.
