Fees
The buyer pays 0.50% on top of the agreed price. In markets #1 to #25 the whole fee goes to the market’s launcher. From #26 the launcher gets 0.25% and Swapmeet 0.25%. Posting, cancelling and launching carry no Swapmeet fee.
Escrow
A sell offer deposits the coins; a buy offer deposits the ETH plus the maximum fee. When an offer is partly filled, the rest stays reserved. Cancel any time to get the unfilled part back; unused fee reserve is refunded automatically.
What the contracts can’t do
- Nobody can withdraw funds held in escrow except the offer’s maker.
- Fee rates and a market’s fee wallet are fixed in code.
- The contracts cannot be upgraded. The owner can only pause new trades; cancels and refunds still work.
What you should still check
Anyone can open a market for any token, including fake copies. Check the token contract address against the project’s official links, and start small. The contracts have not had a third-party audit yet.
