Three kinds. Outcome tokens are a Gnosis ConditionalTokens condition on RollaPredict: you write the question, the outcomes and the resolution rule; the node quorum executes the rule and signs the payout. Oracle rounds settle to a proven aggregation of the feeds you pick. Synthetics are instruments you design: genes, a next-price formula, randomness from a committed seed, your settlement rule, and a creator fee on every trade.

Read at the first block after the end time.Custom API — A public HTTPS JSON endpoint and a path into the response, compared to a threshold or matched to an outcome. Fetched by the nodes at the end time.Resolvers — Named resolver wallets report the outcome after the end; the node quorum submits once the reports agree. Voids after 3 days without a resolution.

What you pay · creation is user-paid

Seed the order books on by default

100 rUSD of your collateral goes into the books; you get LP positions in every outcome book.

Minimum 100 rUSD — the venue's default for 2 outcomes (40 split into a full set for the asks + 30 of bids per book, scaled to your amount). One transaction through RollaBookSeederV2 0xfcb40cb1… after one rUSD approval: it splits, wraps every outcome, opens a 31-bin book per outcome at 0.50 and places the ladder. The bin shares are yours — withdraw them any time, and earn the 0.30% LP fee on every trade.
