The same $10,000 exit. Two very different charts.

Dump into a $90K pool

Price impact plus the LP fee. Everyone watching sees the wick.

Sidebook, −3% floor

Worst case. If a buyer bids higher you meet in the middle. The pool never moves.

Illustrative example with a made-up token and sample amounts.

Your price,
or nothing happens.

Coins never leave your wallet until the settling transaction, and the contract checks both sides' limits on what they actually receive. If anything doesn't add up, nothing moves.

contracts/src/Sidebook.sol
// every settlement, for both makers
function _checkLimit(Order o, uint gave, uint got) {
  if (got * o.sellAmount
      < o.buyAmount * gave)
    revert LimitNotMet();
}

// coins move only here, after the checks
safeTransferFrom(a.maker, b.maker, fillA - feeA);
safeTransferFrom(b.maker, a.maker, fillB - feeB);

Questions

How is this different from swapping on a DEX?+

A DEX swap trades against a pool, and a big trade drags the pool price with it. Everyone sees the red candle and you eat the slippage. Here a seller trades with a buyer directly. The pool is never touched, so the chart doesn't move.

Can Sidebook take my coins?+

The contract can only move your tokens inside a settlement where you receive at least the price you signed, checked on what you actually receive after the fee. If any check fails the whole transaction reverts. You can revoke the approval or cancel on-chain at any time.

What if the price moves while my order is open?+

Your limit is fixed when you sign. If the market runs away from it, the order just doesn't match. Cancel and place a new one whenever you want.

Is a match guaranteed?+

No. An order fills only when someone on the other side wants a price that crosses yours. Public orders sit on the book, where anyone can take them at your price.

Can a lock ever be released early?+

Only if it was created as recoverable, and the app labels every lock either way. A recoverable item can be released by the guardian to its own owner, recipient or sender (never anyone else), normally after a public 3-day countdown shown on the lock (which Sidebook can waive), and never for more than it holds. That covers broken contracts and reviewed early-release requests. Non-recoverable locks can't be touched by anyone until they unlock.

What does it cost?+

0.5% on each side, taken from what you receive and already counted in every number before you sign. The matcher pays settlement gas.

Which tokens work?+

Any ERC-20 on Robinhood Chain that trades against WETH. Reference prices come from the token's own pools.

Leave quietly.

Set a floor, sign once, and let the other side come to you.
