Help, the moment you need it.

Connecting a wallet is free. A total 2% trading fee applies on each trade (0.5% creator + 1.5% liquidity / recipient). There are no deposit, withdrawal, or subscription fees — you only also pay network gas when a transaction is not sponsored.

Anyone may propose the winning outcome by posting a USDC bond (markets created with restricted resolution accept a proposal only from the administrator), which immediately freezes trading in that market. A protocol administrator then declares the final outcome, rejects the proposal, or voids the market. There is no dispute window and no automatic finalization. Once an outcome is declared, winning shares redeem on-chain for $1.00 each and losing shares for $0. If no administrator acts within 30 days of a proposal, anyone may void the market and holders claim a refund, paid in the order claims arrive.This describes what the contracts do when a market can be settled. It does not run end to end on the current deployment: declaring the winning outcome needs a protocol administrator, and the administrator key for these contracts is unavailable, so no market can be resolved and no winning position can be redeemed. Selling out of a market that is still open stays available.

No market on this deployment can be resolved, so no winning payout can be claimed here. New positions, new markets and resolution proposals are switched off while this deployment cannot settle markets; selling out of a position you already hold stays open, so nobody is locked in.

Confirmed on-chain transactions cannot be reversed. You can, however, sell your shares back at the current LMSR price while the market is open.

A void refunds your net amount spent out of the market's remaining collateral, with no fee deducted. Refunds are paid in the order they are claimed and each one draws that collateral down, so a market that cannot cover every holder pays the earliest claims and leaves the last ones short — a late claim can recover less than 100% of what you spent, or nothing. Claim promptly once a market is voided.

2× and 3× are open to everyone. 5× unlocks at $10,000+ traded volume and 10× at $50,000+. Margin is bounded to $50–$2,000 per position.

Set your wallet to Base Sepolia. Predictifi runs on testnet with test USDC that has no monetary value. Markets and trades are on-chain and publicly verifiable.
