Why ChogSweeper
Built for collectors who trade NFTs for NFTs
Marketplaces make you sell, then buy. ChogSweeper lets two collectors swap directly, with the contract as the only middleman.
Speed on Monad
Trades confirm in about a second on Monad's fast blocks, so an offer is accepted and settled while both collectors are still online.
Zero slippage
There is no pool and no price curve. You name the exact tokens and MON on each side, and that is exactly what changes hands.
Atomic, non-custodial escrow
Your NFTs sit in the contract only until the trade settles or you cancel. Terms can't be edited after posting, and the owner can change fee settings only, never move escrowed items.
Multi-asset bundles
Put up to 10 NFTs and an amount of MON on each side of one trade, across any verified ERC-721 collection on Monad.
How it works
How ChogSweeper works
Three steps, one transaction. No order books, no slippage, no waiting for a counterparty to show up with the other half.

Atomic Settlement
Once accepted, both sides swap in a single atomic transaction. No tokens left stuck in escrow.
Common questions
What if nobody accepts my offer?
Nothing happens to your assets. Offers expire at the time you choose, and you can cancel and withdraw at any moment before someone accepts.
Is there a fee?
The person who creates the swap pays a small flat fee in MON. It is refunded in full if the offer is cancelled or declined, and kept only when the trade is accepted. The accepting side never pays a fee. Holders of the Chog collection pay nothing, partner holders get a discount, and the exact amount is shown before you confirm.
What does “atomic” mean here?
Every NFT and every MON amount on both sides moves in one transaction. If any part fails, the whole thing reverts and nothing moves.
Which collections can I trade?
Only collections on the verified list, which the contract itself enforces on both sides of every trade. That keeps look-alike and fake collections out. You can look up any token before you trade it.
