Where Backd works
Backd routes orders to Polymarket, so Polymarket's rules about where people can trade apply on Backd too, along with local ones. We follow them exactly.
The rule
If Polymarket doesn't allow new positions from where you are, or a local regulator has blocked it, Backd won't place an order from there. Your location comes from your network connection. The check happens on the server when the order is placed, not just when a button is shown.
Where backing isn't available
Backing follows where Polymarket and local rules allow it. The call panel tells you before you put anything in.
Backd may also be unavailable in some countries for its own reasons. Visitors there see a notice.
What you can still do
Where backing isn't available you can still follow people, browse markets, run a crew and read records. You can't back a call. If you travel somewhere restricted, open positions stay yours and settle normally. You just can't open new ones until you're back.
