What does this address enforce?

…

Send exactly your quoted amount. This address is single-use and tied to your secret. The KAS can only ever go to the solver (on claim) or back to your refund address (on timeout) — enforced by the covenant script, not by trust.

3 · Fund, then reveal

Send your quoted KAS to the address above from any wallet. Your browser then verifies the solver's USDC lock entirely from chain — every field and the confirmation depth — before enabling the reveal. Until then, your KAS stays refundable.
