FAQ

Do I need to find someone to take the other side?

No. You trade against the pool, so a market is liquid the moment it is created. There's no order book and no waiting for a counterparty.

How is the price decided?

By the AMM. The price of YES is its share of the pool's reserves, which equals the market's live implied probability of YES. Buying a side moves its price up. See AMM & pricing.

What does slippage protection do?

Every buy and sell takes a minOut amount. If the quote moves against you before your transaction is mined, it reverts instead of filling at a worse price — so you never get a surprise fill.

What happens if I hold the losing side?

Losing outcome tokens redeem for 0 at settlement. To exit before then, sell back into the pool or pair-redeem an equal amount of YES + NO for USDC.

Can I lose money providing liquidity?

Yes. LPs are exposed to the market outcome and to imbalance in the pool. You earn swap fees, but the value of your share moves with the odds, so returns are not guaranteed. See Providing liquidity & fees.

When can I claim my winnings?

After the market settles. Settlement happens once the result is known and the market's resolveAfter window has passed — see Resolution & settlement.

Who can create a market?

Anyone can open a market by specifying a YES/NO question and seeding it with USDC. The seed becomes the initial pool liquidity, and the market opens at a neutral 50 / 50 price.

What collateral do markets use?

USDC. All prices, deposits, and payouts are denominated in USDC with 6 decimals.

Does POP hold my funds?

No. POP is non-custodial — all collateral lives in the market smart contract, never with an operator. Settlement and payouts are executed by the contract itself.

Which networks is POP on?

Base and Base Sepolia, plus the Arc testnet for the Circle demo. See Deployments for addresses.
