Terms & Privacy

FlipFlops is a pari-mutuel prediction market on San Francisco resale and surge prices. You deposit USDC on Base Sepolia, back YES or NO on a question with a fixed, published resolution source, and — if your side is right — split the pool with everyone else who was right.

There is no house taking the other side of your bet and no order book: you are betting against the other people in the pool. The mechanics, fee and settlement math are described on How it works and implemented exactly as written there.

You must be 18 or older and legally allowed to use a prediction market where you live. Prediction markets are restricted or prohibited in many places; it is your responsibility to know your local rules, and you must not use FlipFlops from a jurisdiction where doing so is prohibited.

We may decline, suspend or close an account — for example where we believe use is unlawful, abusive, automated at a scale that degrades the market, or aimed at manipulating a resolution source. If we close your account for any reason other than fraud, you keep the right to withdraw your balance.

Deposits go to a deposit address derived uniquely for your account. Once confirmed on chain they are credited to your balance and swept into our treasury wallet. Balances are custodial: we hold the USDC and owe it to you, recorded in a double-entry, hash-chained ledger. We publish live reserves and signed Merkle snapshots of what we owe on Transparency, and you can verify your own balance is included from your Portfolio.

We do not lend, stake or invest user balances. Withdraw any available balance at any time (minimum $2.00); we pay the network gas. Money staked in an open market cannot be withdrawn until that market settles.

Bets are $1.00–$1,000.00 each and cannot be cancelled or sold once placed — there is no cash-out before a market closes.

One fee: 5% of the total pool, taken once at settlement and capped at the losing side, so a winning bet always gets at least its stake back. Voided markets, and markets where nobody backed the winning side, are refunded in full with no fee. We charge nothing for deposits or withdrawals and cover the gas ourselves.

Each market publishes its resolution source, criteria, threshold and resolution time before anyone can bet. After the resolution time, an AI resolver gathers evidence and proposes an outcome; a human administrator reviews it and finalizes, overrides or voids it. Finalization signs an EIP-712 attestation over the outcome and the hash of the evidence, which anyone can verify against our published attester address.

If a source disappears, contradicts itself, or the criteria turn out to be ambiguous, a market may be voided and every stake refunded with no fee. You can dispute any resolution; disputes are shown to the administrator alongside the proposal. Administrator decisions are final — this is not a court, and there is no external arbitration.

Nothing on FlipFlops is investment, financial, legal or tax advice, and nothing here is a security or a regulated financial instrument. You can lose everything you stake. Prices, market questions and any figures we show (including estimated payouts) are informational and change as people bet.

Software has bugs, blockchains reorganize, RPC providers fail, and keys can be compromised. We run this service carefully, with public proofs, but we can't promise uninterrupted availability or that a market will always resolve the way you expect. The service is provided “as is”, without warranties, and to the maximum extent permitted by law our liability to you is limited to your FlipFlops balance.

Don't manipulate a resolution source, run multiple accounts to dodge bet limits, scrape or hammer the service, or attempt to interfere with the ledger or settlement. Bets placed on information you obtained by compromising a source or this service may be voided.

Sign-in. We use Google sign-in. Google sends us your name, email address and profile picture, which we store to identify your account, show your display name (e.g. “Viraat D.”) and contact you about your account. We never see your Google password.

Activity. We store what the product needs: your bets and positions, your ledger entries, your deposit address, deposits and withdrawals (including the on-chain addresses and transaction hashes involved), and any disputes you file. Money movements are permanent ledger rows by design — they are never deleted.

Publicly visible. Other people can see your shortened display name next to bets in a market's activity feed and holders list. The public ledger on Transparency shows only a truncated hash of your user id, not your name or email. Merkle snapshots publish a root — never an individual balance.

Technical. Session cookies keep you signed in. Our hosting and database providers process requests and store data on our behalf, and standard server logs may include IP addresses. We do not sell your data or use it for advertising.

Your choices. Email viraat.laldas@gmail.com to get a copy of your data or to close your account. Withdraw your balance first: closing an account doesn't move money for you, and ledger history is retained for the integrity of the proofs.

We may update these terms; material changes will be noted with a new “last updated” date on this page. Continuing to use FlipFlops after a change means you accept it.

Questions, disputes, data requests or security reports: viraat.laldas@gmail.com. Security issues get priority — please don't publish an exploit before we've had a chance to fix it.
