Set a price cap before you book, or cover a price drop after. Protect one exact flight or any flight on a route and dates you choose, one-way or return, for everyone on the booking. You choose the deductible and how long the lock lasts.
Starts after 24 hours. Drag the cap line, or focus it and use the arrow keys.
While you browse, the CapFare extension recognises the flight on the page and shows what it costs to lock a maximum price for that exact flight, date and fare class. The premium comes from the public formula on the blockchain; the price on the page is only a hint.
Book the flight wherever you like: the airline's website, a travel agency or a comparison site. Just booked? The extension offers a Drop Guarantee: if the same flight gets cheaper within 7 days, you get the difference.
Upload your booking confirmation email, or open your booking page with the CapFare extension and press Verify with CapFare. The booking checker, built to run in a hardware enclave, reads it and only the flight, fare class and price come back (on this testnet demo the checker runs with development keys, as the Transparency page shows). For non-refundable tickets the payout leaves the vault straight away.
Before you book
Lock a maximum price for 3 to 30 days, on one flight or any flight on your route and dates. If the price rises, claim the eligible difference after booking.
Book at €255 with a €180 cap and €5 deductible: €70 back.
Right after you book
Already booked? If the same flight gets cheaper within 7 days, claim the eligible difference.
Book at €220, then the price drops to €195. After a €3 deductible: €22 back.
Deductibles and maximums are the current contract parameters.
Your maximum payout is reserved in a vault before you pay. Check the live balances below.

Protection follows the flight, date and fare class on your verified booking.
The extension recognises the flight on any airline, travel agency or comparison site: from the flight number, or from the route and day where a site shows no flight numbers. On testnet, prices come from our demo price source, so offers appear for demo routes; try it on Skyline Travel, our demo booking site.
Your confirmation is encrypted on your device. Only flight details and a passenger fingerprint are sent to the blockchain.
This demo uses development keys; hardware-enclave verification is not active yet.
Fund the protection vaults and earn premiums. Deposits and withdrawals settle once per epoch.
You can lose money: if many travellers are paid out, the vault shrinks.
Nothing more happens. The cap expires at the end of the period you chose and the premium is not refunded, unless your fare class sold out while the cap was active. Still deciding? Renew it before it ends and the new cover starts the moment the old one stops.
We don't cover availability. If the oracle sees your fare class sold out while your cap is active and unused, the premium goes back to your credit.
Then there is no payout. For refundable tickets we check one day before departure that the booking still exists before paying.
Coverage works for any booking whose confirmation we can verify. In this prototype that is KLM-format confirmations (tested with synthetic examples). More airlines follow.
They keep premiums low. Without them, people who already know a price is about to jump would buy protection seconds before booking, and everyone else would pay for that.
To your CapFare balance in USDC by default. From there you can withdraw to a bank account (IBAN) through a licensed payment partner, or receive another digital asset. On testnet these are simulated.
Two ways. Upload the original confirmation email: its digital signature shows it came from the airline or travel site and wasn't changed. Or open your booking page with the CapFare extension and press Verify with CapFare: our checker loads that page straight from the booking site and sees the booking as it is now, including a cancellation. Either way only the flight, fare, price and a scrambled fingerprint of the lead passenger's name come back, so only your own booking can be used.
No. It is a testnet prototype of price protection. A commercial launch would require a licensed insurer or another appropriately licensed partner.
No. You sign in with a passkey, pay with prepaid credit and never pay network fees. On testnet everything uses test money.
