# Swap

> Exact-in buy or sell on the market OutcomeAmm.

A **pool** handle is one named outcome on the market AMM. Invalid is not tradable. Display mids live on [`market.prices()`](/market/prices). Quote with [`quoteTrade`](/outcome/quote-trade), then swap that size.

```ts theme={null}
const pool = client.pool(outcomeToken, { market: marketAddress, outcomeIndex: 0 })
const result = await pool.swap({
  side: 'buy',
  amountIn: quote.amountIn,
  minAmountOut: (quote.amountOut * 99n) / 100n, // your slippage
  user: owner, // token holder = AA smart wallet, not a nested EOA
})
```

```ts theme={null}
Promise<unknown>
```

Opaque sender result (same shape as your `sendCalls` / wallet path). Buy is collateral → outcome (`OutcomeAmm.buy`). Sell is the reverse (`OutcomeAmm.sell`).

A buy of one named outcome **does** move the others: the AMM splits a complete set, pays out the bought outcome, and keeps the rest. Named prices stay `p_i ∝ 1/x_i` and still sum to 1. After resolve, swaps revert `Resolved`.
