What is TACO?

TACO is an onchain prediction market platform with event prediction markets and price-based perpetual prediction markets.

​
Are event markets and price markets the same?

No. Event markets trade YES/NO outcome shares and settle through a resolution process. Price markets use collateralized long/short positions based on oracle prices.

​
Do I need to provide liquidity to trade?

No. Trading and providing liquidity are separate actions. You can trade without being an LP.

​
Can I lose money as an LP?

Yes. LPs earn fees for taking risk, but fees do not guarantee profit. LP value can fall because of trader wins, market moves, settlement, oracle changes, or liquidity exits.

​
Why did my event trade partially fill?

The trade may have hit a liquidity boundary or the market’s protocol price limit. Partial fill means the protocol filled only the portion that fit within the allowed state.

​
Is a TACO price market a normal perpetual exchange?

No. TACO price markets do not use the traditional long/short funding loop. They use shared pool collateral, oracle prices, fees, liquidation checks, and psi-based solvency accounting. Some markets can enable an optional trader-to-LP funding charge (off by default); when enabled, traders pay funding into the LP pool, with the crowded side paying more.

​
What is psi?

Psi is a pool-level adjustment in price markets. It helps keep payouts aligned with available collateral. It is not a fee and not a funding payment.

​
Why do some pages look empty on my chain?

Some features depend on deployed contracts, indexers, metadata services, or test token configuration. Switch to a supported chain or check whether that market type is live there.
