VOIZ is a prediction market your community can feel. Under the hood it is two pieces:
  1. A complete set — one unit of collateral is always named outcomes + Invalid.
  2. One OutcomeAmm per market — LPs are the book. Named prices satisfy p_i ∝ 1/x_i.
You launch a question. People trade. Settlement stays on-chain.

​
The peg

Split and merge anytime you hold the full set. After resolve, the winner is 1 and the rest are 0. Until then, that identity is true on Conditional Tokens even as AMM mids move.

​
The book

Each market clones one OutcomeAmm. Named outcomes trade against that AMM. Invalid is held for split/merge. On-chain OutcomeAmm.prices()[numOutcomes] is always 0; market.prices().rows does not include that slot. Buy/sell of Invalid reverts. Spot prices (1e18) over named outcomes:
x_i is the AMM’s reserve of outcome i. Named prices sum to 1. Invalid is not in that sum. A buy of Yes is not minting a set into the trader’s wallet. The AMM splits collateral, pays out Yes, and keeps the rest of the set as inventory. Yes reserve falls; other named reserves rise. Yes’s price goes up; the others go down. No separate rebalancer is required. How LPs work.

​
Who gets paid

totalFeeBips = 100 protocol + lpBips + creatorBips + referrerBips. Variable cuts (lp + creator + referrer) cap at 150 bps. SDK defaults: LP 80, creator 50, referrer 20. Same schedule on buy, sell, and redeem. LPs do not get a USDC stream. Their cut is inventory. Mark-to-market vs cost is the LP book. Worked numbers: LP calculator.

​
From spark to settled

  1. Create — createMarket. Pass seedWei + oddsBps for create-and-seed in one factory tx (approve the factory). Omit seedWei for an empty book.
  2. Seed — if you did not seed on create: market.seed (addFunding with opening odds, Invalid = 0).
  3. Trade — people buy / sell one named outcome at a time.
  4. Resolve — payouts are published. Named shares are now 0 or 1.
Trading stops at resolve on purpose. buy / sell revert Resolved once Conditional Tokens has a payout denominator. A live curve quoting 0.62 while redemption is 1 or 0 is free arb on LP inventory. After resolve, /chart pins the winner at 100 and losers at 0. Periodic price snapshots skip resolved markets. Creators can one-way pauseTrading (OpenZeppelin Pausable) before resolve; buy/sell/addFunding stop, removeFunding and redeem stay open. Outcome shares: market.redeem. LP shares after resolve: market.redeemLp (burns pool shares, redeems the basket to collateral). Open-market LP exit is still removeFunding (token basket, not cash).

​
What this is not

Not one Uniswap pool per outcome. Not PositionManager NFTs. Not a rebalancer that trades complete sets through independent books. Not an order book. Next: liquidity · trade
