Lines: your rails, your risk

You draw a corridor on a live price and take a side: hold if it keeps both rails to the end, or breach if one goes first. A decentralized oracle prices it, the chain settles it, and the backstop pays it.

In one paragraph

You drag an angled band of two rails onto the live price of any market, then take a side and open a position in $HOLD. Three controls shape it: how far it leans, how far apart its rails sit, and how long it runs. Those set one number, the probability the corridor survives, and each side's multiplier is the inverse of its own outcome, final the moment your entry locks to a signed price report.

Then it ends one of three ways. The run reaches its end untouched, which pays the hold side in full. A rail is touched, which pays the breach side and closes hold at zero. Or you cash out early for a known amount. Whatever you collect comes from the backstop, and every step is an onchain event anyone can replay. The only difference with Sideline is whose corridor you back: your own here, somebody else's there.
