Pick the coin, the size and your price. Selling locks your coins in the desk contract; bidding locks your HYPE. Nothing leaves your control except into a fill.

Post a bag of any Elysium coin at your price, or bid HYPE for one. The other side fills it straight from the desk: no pool, no slippage, no chart that moves against you.
Selling a bag into a pool pushes the price down as you sell. The bigger the bag next to the pool, the more of it you give away. These are the main pools of Elysium coins right now, and what a market sell of each size would lose to price impact.

Price impact for a full-range pool, before the pool's own fee. Concentrated pools can do better or worse. On Haggle the price is the one both sides agreed to; the only cost is the 0.5% fee.
Pick the coin, the size and your price. Selling locks your coins in the desk contract; bidding locks your HYPE. Nothing leaves your control except into a fill.
Every offer has its own link. Send it to the buyer you met in a chat, or name their wallet so only they can fill it. Open offers sit on the board for anyone.
The taker sends their side and both sides change hands in the same transaction, at the posted price. Allow parts and it can fill in pieces.
Whatever is not filled comes back to you the moment you cancel. Expired offers stop filling and wait for you to take them back.
A fill pays exactly the posted rate, rounded in the maker's favour by a fraction of a wei. There is no pool in between to front-run.
The coins and the HYPE move in one transaction. If either side fails, the whole fill reverts and nothing changes hands.
The contract has no admin, no pause and no upgrade. Locked coins and HYPE can only go to a taker in a fill or back to their maker.
For a small amount, do. For a bag that is big next to the pool, a market sell walks the price down and you get far less than the price you saw. A buyer on the desk pays the agreed price for the whole bag.
Any ERC-20 on Elysium: KNTQ, launchpad coins, anything with a contract address. Coins that tax transfers are counted by what actually arrives in the desk.
Put their wallet in "Only this wallet can fill". The offer still shows on the board, but nobody else can take it. Then send them the offer's link.
0.5% of the HYPE side of each fill, paid out of the HYPE. Posting and cancelling cost only gas.
No. The contract is small and tested, including random checks that it never pays out more than it holds. Start with amounts you are fine to lose.
