What is Myriad?
An order-book market matches resting orders off-chain and settles them on-chain; an AMM uses a different liquidity path. Select the model before comparing fees or controls. The web app documents fill-or-kill market orders that require a full fill, while API and CLI also support fill-and-kill partial execution. A limit order that fills immediately receives taker treatment.
Search crypto, politics, finance and other topics, then read the market Rules, closing time and resolution source. Ordinary resolved winners can be claimed from the portfolio. Voided markets instead use the position’s market value at cancellation, which may differ from the original stake. Perpetual Sentiment Markets are another format: they track opinion and never resolve.
