Compliance

Compliance & responsible use

How Predictifi operates transparently — our fee schedule, leverage rules, and how markets resolve. Every number on this page is enforced on-chain.

Effective June 23, 2026

Transparent fees

Every fee is disclosed upfront and enforced on-chain. No hidden deductions.

On-chain & verifiable

Markets, prices and resolution all settle on Base Sepolia. The contracts are open source and independently verifiable.

Positions carry risk

Outcomes are uncertain and you can lose your funds. Participate thoughtfully.

01 · Fee transparency

One transparent fee

Predictifi charges a single transparent trading fee. The total fee is 2% on each trade, split into a 0.5% creator fee, a 0.5% resolver fee and a 1.0% liquidity / recipient fee. There are no other trading fees beyond the schedule below.

Total per trade

0.5% to the market creator, 0.5% to the resolver reward, 1.0% to liquidity — applied to the trade amount, nothing on top.

Total trading fee2%Charged on each trade (buy and sell), taken from the trade amount

Creator fee0.5%Paid to the wallet that created the market

Resolver fee0.5%Accrues per market and is paid to the correct resolution proposer when the outcome is declared

Liquidity / recipient fee1.0%Paid to liquidity providers and the protocol fee recipient

Position opening fee0%No separate fee to open or hold a position

Refund fee (voided markets)0%No fee is deducted. A void refunds your net amount spent out of the collateral the market has left, in the order claims arrive, so a late claim can pay less than you spent

02 · What it is

A market, not a casino

Predictifi is a prediction market protocol, not a casino or sports book. Prices are set by an on-chain logarithmic market scoring rule (LMSR), so each outcome's price reflects the crowd's implied probability of a real-world event.

Prediction markets aggregate collective forecasts into a single price.
Outcomes are determined by real-world events — not randomness or house mechanics.
Predictifi does not set odds; prices move only as participants trade.

Predictifi is deployed on Base Sepolia, a test network, and positions are denominated in test USDC that has no monetary value. The contracts are open source and covered by an in-repo Foundry test suite (unit, fuzz and stateful-invariant); they have not been reviewed by an external security firm.

The risk of losing your position is real. Only take positions you can afford to lose.

03 · Leverage

Volume-gated tiers

Eligible markets support leveraged positions. Higher multipliers unlock as your traded volume grows, and every leveraged position is bounded by a fixed margin band of $50–$2,000.

2×Open to everyone

3×Open to everyone

5×Requires $10,000+ traded volume

10×Requires $50,000+ traded volume

If price moves against a leveraged position past its liquidation threshold, the position is closed automatically and the margin is forfeited. The liquidation price is always shown before you open a position.

04 · Resolution

Administrator-declared

Resolution is administrator-declared. Anyone may propose the winning outcome by posting a USDC bond, which immediately freezes trading in that market. There is no dispute window and no automatic finalization:

A protocol administrator declares the final outcome, after which winning positions can redeem.
The administrator may instead reject the proposal — reopening trading — or void the market outright.
If no administrator acts within 30 days of a proposal, anyone may call the permissionless void-stale function to void the market.
A voided market refunds your net amount spent out of that market's remaining collateral, with no fee deducted. Refunds are paid in the order they are claimed and each one reduces what is left, so a market whose collateral does not cover every holder pays the earliest claims and leaves the last ones short — a late claim may recover less than you spent, or nothing.

Resolution therefore depends on a protocol administrator acting. Resolution criteria and the resolution source are shown on each market page before it closes.

05 · Eligibility

Responsible participation

You must be of legal age in your jurisdiction and ensure that using a prediction market protocol is lawful where you live. Predictifi does not provide investment advice. A few principles to participate responsibly:

Only risk what you can lose: Treat your USDC as discretionary.
Understand the price: A low price implies the crowd thinks an outcome is unlikely.
Take breaks: Step back if you find yourself trading reactively.

06 · Integrity

Coordinated manipulation of market prices;
