PredMart FAQ
Common questions about trading on prediction markets with PredMart.
How much leverage can I use?
PredMart lets you trade with up to 5x. Higher leverage means bigger potential wins but also bigger potential losses. See Margin and Liquidation for details.
Can I take the other side of an outcome?
Yes. You can back Yes or No on any outcome. If you think something will NOT happen, back No. If you think a team will lose, pick the other team. Both directions work the same way and use the same fees.
What fees does PredMart charge?
| Fee | Rate | When charged |
|---|---|---|
| Entry fee | 0.1% of position size | Taken from your margin when you open |
| Profit fee | 10% on winnings | When you close, only if you made money |
| Operation fee | Up to $0.01 | Per action |
| Holding fee | Builds up over time | While your position is open |
The profit fee splits 7% to liquidity providers and 3% to PredMart. Full breakdown at Fees.
When does my position get liquidated?
If the price moves against you far enough, your trade is closed automatically and you lose your remaining margin.
Watch your margin and add more or close your position before you hit that level. See Margin and Liquidation.
Can PredMart take my money?
No. Your money stays in the smart contract. The PredMart team cannot take it, move it, or freeze it.
What is the minimum to start a position?
The minimum margin per position is $1, no matter what leverage or size you choose.
How do liquidity providers earn money?
LPs put USDC into a shared pool. They earn from:
- Entry fees (0.1% of each position)
- Their share of profit fees (7%)
- Holding fees from open positions
- When traders lose money
The pool value goes up and down as positions open and close. Each market is capped at 10% of the pool to spread risk. See Providing Liquidity.
Is PredMart safe?
Your money is in the smart contract, not in PredMart wallets. The team cannot take it. There is an emergency pause if a problem is found. Each market is capped at 10% to spread risk.
That said, all smart contracts carry some risk. Leverage makes both wins and losses bigger. See Security.
What blockchain is PredMart on?
PredMart runs on Base. It uses USDC at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
What is slippage tolerance?
The default slippage tolerance is 5%. This protects you if the price moves between when you click and when your trade goes through. You can change this in the trade screen.
Can I trade any prediction market?
You can trade outcomes on markets that PredMart supports. Not every market is available.
How is this different from trading directly on a prediction market?
| Aspect | Trading directly | PredMart |
|---|---|---|
| Leverage | None (1x) | Up to 5x |
| Taking the other side | Sell shares you own | Back No or pick the losing option |
| How it settles | Matched orders | Pool pays out |
| What you put up | Buy shares outright | Post margin, pool covers the rest |
| Blockchain | Varies | Base |
With PredMart, you never hold actual prediction market shares. You hold a position that tracks the outcome.
