Genie NFT Aggregator Explained: How Floor Sweeping Works

Genie was an NFT marketplace aggregator. It did not host its own inventory in the way a traditional marketplace does. Instead, it read listings from several marketplaces and showed them in one place, so a buyer could see the cheapest items in a collection regardless of where each one was listed.

The feature that made it popular was bulk buying. A collector could select a number of listings, add them to a cart, and complete the purchase in one transaction. That action is called sweeping the floor, because it clears the lowest-priced items off the bottom of a collection's listings.

A few points define what Genie was:

• An aggregator, not an exchange. The NFTs stayed listed on their original marketplaces. Genie routed the purchase to the right contracts.
• Built for Ethereum NFTs. It focused on popular Ethereum collections, where floor prices and listing depth made sweeping worthwhile.
• Aimed at active traders. Features like cart-based buying, filters by trait and rarity, and sorting by price suited people who flip or accumulate many items, not casual one-off buyers.

The idea behind it is simple. NFT liquidity was split across several marketplaces, and the best price for a given item could sit on any of them. An aggregator solves that fragmentation by presenting the combined order book and letting you act on it with a single wallet signature.

This guide covers what sweeping is, how aggregators work under the hood, where Genie's story went after the Uniswap acquisition, what to be careful about, and what to use if you want similar functionality today.

Genie started as an independent NFT aggregator during the 2021 NFT boom, when trading volume was spread across a growing number of marketplaces. It built its reputation on speed and on making bulk purchases easy.

In 2022, Uniswap Labs acquired Genie. Uniswap was already the best-known decentralized exchange for fungible tokens, and the deal gave it an NFT product and a team with experience in marketplace aggregation. The acquisition was widely described as Uniswap's move to extend its token-swapping business into NFTs.

After the deal, the Genie interface and technology were folded into Uniswap's own NFT offering, which Uniswap presented as an aggregator inside its web app. In practice, that meant the Genie name faded as a stand-alone brand, and the product continued under Uniswap's branding.

Two things are worth keeping separate:

• Genie versus other aggregators. Another well-known aggregator, Gem, was acquired by a different company around the same period. They are different products with different histories, and the two are often confused.
• The product versus the brand. Searching for Genie today mostly returns unrelated results, such as AI models, chatbots and small crypto tokens. That does not mean the NFT aggregator is still operating under that name.

If you are reading an older article that calls Genie the best way to sweep floors, treat it as a snapshot of a specific period. The sensible way to learn the current state is to check Uniswap's official product pages and announcements directly rather than rely on third-party summaries.

Sweeping the floor means buying the lowest-priced listings in an NFT collection, usually several at the same time. The floor price is the cheapest price at which any item in a collection is currently listed. A sweep takes the bottom of that list and buys it.

People sweep for several reasons:

• Building a position quickly. A collector who wants exposure to a collection can acquire many items at once instead of waiting for individual deals.
• Moving the floor. Removing the cheapest listings lifts the floor price, which can change how a collection looks on trackers. This is a market-moving tactic, and it carries the risk that other sellers simply list at the new, higher floor.
• Collecting a set. Someone assembling many items for a project, a game or a community can buy them in one go.
• Capturing mispriced listings. Sometimes items are listed far below others, by mistake or by a seller in a hurry.

Sweeping is not a guarantee of profit. The floor is only as meaningful as the demand behind it. If few buyers exist at higher prices, the floor you lifted can fall back, and you are left holding many items that are hard to resell individually.

Because floor items are usually the least desirable in a collection, sweeping also tends to mean buying commons or items without rare traits. Traders who sweep often filter by trait first, so they take the cheapest items within a preferred group rather than the cheapest overall.

Nothing here is investment advice. NFT prices can fall to zero, and a sweep multiplies your exposure to that risk.

An aggregator works in three layers: it reads listings, it builds a purchase, and it executes that purchase through smart contracts.

1. Reading listings. The aggregator indexes listings from supported marketplaces, using their public data. It shows them together, sorted by price, with filters for traits and rarity.
2. Building the cart. You select items. The interface calculates the total cost, including marketplace fees, any creator royalties that apply to each listing, and the aggregator's own fee.
3. Executing the purchase. One transaction calls a router contract. The router then fills each order on its original marketplace, using that marketplace's rules. If everything succeeds, the NFTs arrive in your wallet.

A typical sweep looked like this:

1. Connect a wallet that holds enough ETH for the items and gas.
2. Open the collection and sort listings by price, low to high.
3. Choose a quantity or select items individually.
4. Review the cart total and the listed sources.
5. Confirm the transaction and sign in your wallet.
6. Wait for the transaction to confirm, then check the items appear in your wallet.

A few technical details matter. Listings can change between the moment you view them and the moment the transaction is mined, because someone else can buy an item first or a seller can cancel. Good aggregators let you choose whether to skip unavailable items or cancel the whole purchase. Some also let you set a maximum price so a sudden change does not cost you more than planned.

Because one transaction touches many contracts, gas costs are higher than for a single buy, though usually lower than buying each item separately.

Sweeping is efficient, but it concentrates several risks into one signature. Understand them before you buy.

Costs

• Gas. A multi-item transaction uses more gas than a single purchase. During busy periods, gas alone can erase the margin on low-priced items.
• Fees. Marketplaces charge their own fees, and an aggregator may add one. Creator royalties can apply depending on the collection and the listing.
• Failed transactions. If a listing disappears mid-transaction and the purchase is set to all-or-nothing, you can pay gas and receive nothing.

Market risks

• Thin demand. Cheap items are cheap because few people want them. Reselling many of them can be slow.
• Stale or manipulated floors. A floor price can be propped up by a few listings or by wash trading, where one party trades with itself to create fake activity.
• Fake or copycat collections. Scammers mint lookalike collections with similar names. Always confirm the contract address from the project's official channels.

Security risks

• Approvals. Buying can require token approvals. Unlimited approvals leave a permission open after the purchase.
• Phishing. Fake aggregator sites copy real interfaces to collect signatures. Bookmark the correct site rather than following links from search ads or messages.
• Malicious items. Some NFTs link to harmful sites or trick you into signing a transfer when you try to view or list them.

A sensible habit is to keep a separate wallet for trading, holding only what you plan to spend, and to review each transaction preview line by line before signing.

This is the question most readers need answered, and it is worth being straightforward: public reporting gathered for this guide do not confirm whether a Genie-branded NFT aggregator, or the Uniswap NFT aggregator built from it, is operating today.

What can be said with reasonable confidence:

• Genie was acquired by Uniswap Labs in 2022 and its technology became part of Uniswap's NFT offering.
• The stand-alone Genie brand is no longer how most people find the product, and searches for Genie now return mostly unrelated material.
• NFT products change status often. Marketplaces have shut down, paused or merged, and one example from the candidates here is Foundation, an Ethereum art marketplace whose team took it offline indefinitely on April 27, 2026 after a failed sale.

Before relying on any aggregator, check these things:

1. Official announcements. Look at the product's own blog and social accounts for notices about sunsetting, migration or changes.
2. The interface itself. If the NFT section is missing or shows a wind-down notice, the product is not a dependable option.
3. Your existing assets. If you bought through an aggregator earlier, your NFTs are in your wallet and do not depend on the aggregator. Only the interface goes away, not your ownership.
4. Open listings. Listings on the original marketplaces stay active until cancelled or expired, regardless of what happens to an aggregator.

If you cannot confirm that a product is live, do not connect a wallet to find out. Use a marketplace whose status you can verify.

Searching for Genie turns up a mix of tokens and projects that have nothing to do with the NFT aggregator. The results include a listed GENIE token with a very low price and a tiny market capitalization, a separate token named Benie The Genie, and a discontinued Ethereum token called GENIE AI that describes itself as an AI agent platform. Others are about Google DeepMind's Genie world models and a TikTok chatbot of the same name.

The NFT marketplace Genie was not known for a native token. That matters, because lookalike tokens are a common way to lose money:

• Name reuse. Anyone can deploy a token called Genie. A name match says nothing about a link to the NFT product.
• Fake airdrops. Scam sites sometimes claim that users of an NFT aggregator are owed a token, then ask you to connect a wallet and sign.
• Price pages. Price trackers list every token with a similar name. A price page showing a token does not mean it is related to a marketplace you used.

Practical steps:

1. Do not buy a token because its name matches a product you remember.
2. Treat any unexpected airdrop claim as hostile until verified through the project's official channels.
3. Check the contract address, the deployer and the project's own statements before interacting.
4. If a site asks you to approve spending for a token you did not buy, close it.

For current prices of any token, use a reputable tracker and compare several, because small tokens can show very different figures across sources.

Whatever tool you use to buy several NFTs at once, a short defensive routine reduces most of the avoidable losses.

Before you connect

• Reach the site through a bookmark you saved earlier, not through ads or messages.
• Use a dedicated wallet for NFT trading, funded only with what you intend to spend.
• Prefer a hardware wallet for anything of value, and keep it for holding rather than trading.

Before you sign

• Read the transaction preview. Check the recipient contract, the amount and any approval requests.
• Set a maximum total price if the interface allows it.
• Avoid blanket approvals for all items in a collection unless you understand why they are needed.
• Confirm the collection's contract address against the project's official channels.

After you buy

• Check that the items landed in your wallet.
• Review and revoke approvals you no longer need, using an approvals checker in a wallet or block explorer tool.
• Do not click links embedded in unfamiliar NFTs, and do not interact with items you did not buy. Unsolicited NFTs are often bait.

General habits

• Never share your seed phrase. No marketplace, aggregator or support agent needs it.
• Be wary of direct messages offering help, deals or giveaways.
• Keep a record of transactions for tax purposes. Rules vary by country, so check local requirements.

These steps will not remove market risk, but they protect you from the most common wallet-draining tricks, which target people moving quickly through multi-step purchases.

If you want the benefits Genie offered, such as seeing the best price across sources and buying quickly, there are several approaches. Features and availability change, so confirm each option's status before using it.

Approach	How it works	Examples from this site's list
Pool-based floor buying	An NFT collection is deposited into a vault that issues ERC20 tokens, so you can buy an NFT from the pool at a floor-style price without waiting for a seller	NFTX
Chain-specific marketplaces	A marketplace on a particular chain with its own listings and buying tools	Stargaze (Cosmos), AtomicHub (WAX and EOS-family)
Automated strategies	Tokens whose trading fees fund buying, relisting and burning NFTs, for experienced and risk-tolerant users	TokenWorks (NFTStrategy)
Other aggregators	Separate tools that combine listings from several Ethereum marketplaces	Check current status before use

Some notes on choosing:

• NFTX suits collectors who want instant exits and entries at the pool's price, but vault pricing can differ from the best individual listing, and you generally receive a random item from the pool rather than a chosen one unless you pay for specific items.
• Stargaze and AtomicHub make sense if the collections you want live on those chains, since an Ethereum aggregator will not list them.
• TokenWorks is a different category. It is an automated strategy protocol, not a marketplace for sweeping, and it carries risks that suit experienced users.
• Foundation is a reminder to check status: it was an art marketplace and is offline as of April 27, 2026.

For physical collectibles rather than digital art, Courtyard offers vaulted, insured items sold as digital packs, which is a different model from floor sweeping.

Floor sweeping looks simple on the screen, but the risk sits in the details. A few questions help decide whether a bulk purchase makes sense.

Is there real demand? Look at sales history, not only listings. A floor with many recent sales at that price is healthier than one supported by a handful of listings and little trading.

What is the full cost? Add gas, marketplace fees, aggregator fees and royalties. Compare the total with what you could realistically sell the items for, after fees again.

Can you exit? Floor items can be hard to sell in bulk. If you plan to flip, decide your target price and your tolerance for holding before you buy.

Is the collection genuine? Verify the contract address through official channels. Watch for copycat collections and wash-traded volume.

Can you afford the loss? NFT prices are volatile and can fall sharply. Only spend what you can lose.

For readers in gambling-adjacent corners of crypto, a related note: some NFT projects and mint mechanics resemble lotteries or prize draws. If an activity involves paying for a chance at a random outcome, it may count as gambling in your jurisdiction. You must be 18 or older, or the legal age where you live, and you should check local laws before taking part. Do not use tools to bypass location rules, age checks or identity verification.

Treat this guide as background, not advice. Confirm each product's current status, fees and rules on its own official pages before you commit funds.
