Unicle — Polymarket markets, settled by a Uniswap v4 hook

How Unicle works

Three moves, one settlement

Unicle reads live Polymarket markets, brings each price on-chain as a reference, and clears positions through a single Uniswap v4 hook.

01 / Mirror

Mirror Polymarket

Odds, depth and volume for every open question are pulled live from Polymarket and normalized into clean yes/no probabilities.

02 / Quote

Quote in the hook

A Uniswap v4 hook reads the live market price in beforeSwap as the reference for the pool — pricing each YES/NO swap against it.

03 / Settle

Settle on Ethereum

Positions clear against the PoolManager on Ethereum. One transaction, fully on-chain, with the hook booking fees back to the pool.

Settlement, encoded in the hook flags

Unicle isn't a frontend bolted onto a DEX. The pricing logic lives in the pool itself: a v4 hook whose permission bits are mined into its address.

beforeSwap reads the live Polymarket price as the pool's reference before the trade settles.
afterSwap books fees back to liquidity providers once the position clears.
The hook address is CREATE2 salt-mined so its low bits match the permission mask the PoolManager validates.

function getHookPermissions()
  public pure override returns (Permissions memory) {
  return Permissions({
    beforeSwap:        true,  // read reference price
    afterSwap:         true,  // book fees
    beforeAddLiquidity:true,
    // …remaining flags false
  });
}

// salt-mined so address & mask == required bits
PoolKey({ currency0: USDC, currency1: YES,
  fee: 3000, tickSpacing: 60,
  hooks: IHooks(UNICLE_HOOK) });

The token

$UNCL

$UNCL governs the Unicle settlement hook and shares in the fees it books. Holders steer which markets are listed and how pool fees are split.
