Predictifi runs on Base. Connect any Ethereum wallet and sign a one-time message to prove the address is yours — this is Sign-In with Ethereum (SIWE). It is a signature, not a transaction: it costs no gas and never moves funds. Positions are denominated in USDC.

Browse open markets by category, then pick a side — Yes or No. Each side has a price between 0 and $1 that reads as the crowd's implied probability: a Yes price of 40¢ means the market thinks there's roughly a 40% chance.

Prices are set by an on-chain Logarithmic Market Scoring Rule (LMSR). Buying a side nudges its price up and the other side down — so the more confident the crowd, the more it costs to take that view. Your quote always reflects the live curve before you confirm.

On eligible markets you can amplify a position with leverage. You post margin (your slice of the cost) and the Leverage Vault lends the rest. 2× and 3× are open to everyone; 5× unlocks at $10,000+ traded volume and 10× at $50,000+. Margin is always between $50 and $2,000.

If the price moves against you past your liquidation level, the position closes and the margin is forfeited. A 1-hour cooldown and a time-weighted price gate protect you from unfair, single-spike liquidations — and the liquidation price is shown up front.

You don't have to watch the chart. Attach a stop-loss to exit if the price falls to a level you choose, or a take-profit to lock in gains once it rises to your target. An off-chain keeper watches the market and executes the order on-chain when your trigger is hit — it can never move funds beyond the order you authorised.

When the event happens, the market resolves through optimistic resolution — three phases, all on-chain:

A market that can't be resolved unambiguously is voided, and every position is refunded in full.

Once a market finalizes, each winning share redeems for $1.00 in USDC and losing shares for $0. Redeem from your portfolio in a single transaction — the USDC lands straight back in your wallet. Activity along the way also earns rewards points, seasons and achievements; these points are non-redeemable, have no cash value, and are not a token.
