PredictionToolkit
What is OPINION?
Browse macro, crypto, pre-TGE, equities, politics and sports questions, then compare the event’s outcome contracts. Read the measurement period and resolution source before expressing a view. Portfolio analytics show positions and performance, while points and VIP programs track activity or fee discounts separately from realized profit.
Resting liquidity can qualify for maker incentives, but a limit order is not automatically a maker order. Fees apply per matched fill, so crossing several prices can matter. For small tickets, the minimum charge can dominate the curve-based percentage even after multiplicative discounts; the platform’s coverage of trade-settlement gas does not cover every other action.
Who it is for
- Traders researching macro-event contracts.

Workflows with OPINION
Research a macro event
Match the measurement period and resolution source to the forecast you intend to express.
Compare order costs
Check whether the order rests or crosses, inspect its matched-fill path and include the minimum fee for a small ticket.
Integrate data before execution
Start with documented identifiers and streams, then add authenticated execution after validating the data workflow.
Pricing and total cost
Makers are not charged trading fees. Taker fees use market coefficient × P × (1−P), applied to notional with multiplicative discounts. The docs describe rates up to 1%, subject to a $0.25 minimum, so small trades can have a higher effective percentage. Minimum order and withdrawal amounts are $5. Trade match/settlement gas is covered, while some other actions have user-paid gas.
Getting started
Before you start: Discounts do not remove the $0.25 minimum fee.
- Read the selected market’s rules and choose a wallet or supported social login.
- Confirm settlement asset and chain, then inspect the market’s coefficient and discounts.
- Check whether a limit order will rest or match immediately, then track fills, PnL and resolution.
The $0.25 minimum fee still applies when discounts reduce the curve-based fee.
