Borrow against a bet you already hold.
Your YES/NO position in a Registrai market is locked capital until the market resolves. Pledge it as collateral and borrow USDC against its live AMM mark — without selling. Suppliers earn the interest. The collateral is valued at a depth-capped mark (never above 10% of the opposite reserve) so a thin pool can't be manipulated into an over-loan, and every loan is force-closed before resolution so the pool never eats the binary cliff.

Borrow against a bet
Earn 100 Registrai credits for using the pool.
Borrow against a position or supply USDC, then claim. Credits are soulbound, onchain reputation for early protocol users — earned, not bought. Requires the Connect Twitter quest first (one handle per wallet, keeps the leaderboard honest).
depth-capped collateral
A position is never valued above 10% of the pool's opposite-side reserve, with a 40% max LTV. A position's recoverable value is bounded by what the pool can actually pay out on liquidation — so spiking a thin AMM mark to over-borrow is net-negative. Validated by a 10,000-run adversarial fuzz.
the cliff guard
Binary options resolve to exactly $1 or $0 — you can't margin-call that discontinuity. So loans are force-closeable by anyone in the 2h before expiry, with a 5% liquidator bonus, and a keeper writes off resolved-loser loans. In-the-money loans always self-close; the bounded residual on out-of-the-money loans is socialized honestly.
fair liquidation
A liquidator takes only shares worth (owed × 1.05); the surplus returns to the borrower, sized off the mark recorded at origination so it can't be gamed by crashing spot mid-liquidation. Suppliers' idle USDC is tracked internally, so a token donation can't skew the share price.
