Cryptoslam

CryptoSlam is a free website that tracks NFT sales. It covers more than 15 blockchains, Solana among them. It ranks NFT collections and whole chains by how much has sold. Its docs call it an "NFT aggregator".

What sets it apart is how it treats fake volume. When a trader buys and sells to themselves to make a collection look busy, that is a wash trade. CryptoSlam shows these trades in their own column and leaves them out of its sales totals.

You can browse it without a wallet. Randy Wasinger started it in 2018, and it is based in Kansas. As of October 2026 the site is live, and its X account posts market news most days.

How CryptoSlam works: on-chain sales, minus wash trades

CryptoSlam reads NFT sales from each chain it covers. It then groups them by collection, by chain and by time period. Each sale links back to a block explorer, which on Solana is Solscan.

Each chain page shows sales, buyers, sellers and trade counts. You can view the last day, week, month or all time. Next to these sit three wash-trade columns: wash volume, wash trades and wash share.

The Solana page has a month-by-month table back to mid-2021. It shows how much the filter can take out. In March 2024 it counted about $249 million of real Solana NFT sales. It set aside a further $161 million as wash trades.

The filter is CryptoSlam's own, and the rules are not public. In early 2023 it was widened to catch traders who swap near-identical NFTs to farm rewards. That change cut out more than 80% of Blur's volume since its airdrop, Decrypt reported. Wasinger told Decrypt there were "some judgment calls in the code".

CryptoSlam NFT rankings and Solana NFT sales data

The main product is a set of free rankings:

• NFT collection rankings by sales volume, with filters for chain and time period.
• Blockchain rankings that compare total NFT sales across chains.
• Top sales pages that show the biggest single NFT sales in a period.
• Collection pages with sales history, buyers and sellers, average price and rarity.

You can export the chart data. Coverage goes beyond standard NFTs. In October 2026 the home page listed Ethereum, Solana, Bitcoin, Polygon and BNB Chain. It also listed Arbitrum, Avalanche and the trading-card firm Panini's own chain. There are fan token rankings too.

For Solana users, the Solana chain page is the one to bookmark. It lists Solana's top collections and biggest sales, with wash trades split out. Most daily posts on CryptoSlam's X account are about Ethereum. Solana does show up, though. On 22 October 2026 it named the Bored Ape Yacht Club "Mudwater Packs" as the top Solana collection of the week.

CryptoSlam 500 NFT Index and ETH NFT Composite

CryptoSlam also runs indexes that track the NFT market as a whole, a bit like a stock index. The main one is the CryptoSlam 500 NFT Index. It holds 500 collections from many chains, Solana included, and is reset each day. The weights come from each collection's size and how many people trade it. A second index, the ETH NFT Composite, looks at Ethereum.

CryptoSlam annual NFT market reports

News sites often quote CryptoSlam's yearly totals. By its count, NFT sales came to $8.83 billion in 2024, much the same as the year before. Solana came third, behind Ethereum and Bitcoin, Cointelegraph reported.

The next year was weaker. Sales fell to around $5.63 billion, per Cointelegraph. Yet more and more NFTs kept being made. For live Solana figures, use the Solana page on the site.

CryptoSlam API: public and enterprise

There are two ways for developers to pull the data:

• Public API: two free endpoints, for the top 100 collections and the top 100 sales. You don't need to sign up or get a key.
• Enterprise API: paid endpoints for chains, collections, fan tokens, indexes and single sales. Sales data includes the marketplace, buyer and seller. Prices are not public, so you fill in a form to get a quote and a key.

The "API" link in the site's footer points to an apiable.io address. When we checked in October 2026, that domain did not load. Use the docs pages instead.

Who CryptoSlam is for

• NFT collectors and traders who want to compare sales across chains, or check whether a collection's volume is real. The wash-trade columns are the reason to use it over a marketplace's own stats.
• Writers and researchers who want a well-known source for monthly and yearly NFT totals. Say in your copy that the figures leave out wash trades by CryptoSlam's own rules.
• Developers and data teams who need NFT data from many chains through an API. The free API only covers the top 100 lists, so anything deeper means asking for a price.

It is a poor fit if you only trade on Solana and want live floor prices, listings and bids. A Solana marketplace gives you those directly.

Is CryptoSlam legit? Risks and limitations

CryptoSlam is a real, well-known company with named backers. The site is read-only, and you don't need a wallet to use it. Its docs list only MetaMask and WAX as wallets you can link, and that is optional. The real risks are about what the numbers mean, and about fake copies of the site.

• You can't check the wash filter. The rules are private and, by the founder's own account, involve judgment. Two trackers can show different volumes for the same collection. Treat CryptoSlam's figures as its estimate.
• "NFT" is used loosely. On 26 October 2026, the top daily "NFT" sales on the home page included a Sablier vesting stream on Solana. They also included DeFi liquidity positions on Arbitrum and Avalanche. These are financial positions, not collectibles, and they can inflate a chain's totals.
• It earns money from the projects it lists. It sells ads through SlamAds. It also charges an optional $2,000 fee to list a collection faster. We found no claim that either affects rankings, but you should know about both.
• Fake copycat sites. Scam checkers list lookalike domains such as cryptoslam-nft.tech. The real site is cryptoslam.io. A data site will never need your seed phrase.
• Two tokens share the SLAM name. CryptoSlam's planned SLAM token (see below) is not the same as Slam (SLAM) on BNB Chain. That token, listed on some exchanges, belongs to an unrelated charts, swap and casino project.

CryptoSlam vs DappRadar, Magic Eden, Tensor and Dune

• DappRadar was the best-known rival for rankings across many chains. It shut down in November 2025, saying it had become "financially unsustainable". That leaves CryptoSlam as one of the few cross-chain NFT sales trackers still running.
• Magic Eden ME$0.051-1.3% and Tensor TNSR$0.027+13.0% are Solana NFT marketplaces with their own stats, floors and live orders. They are better for trading on Solana. CryptoSlam is better for comparing chains, and for volume with wash trades taken out.
• Dune lets you write your own queries against raw chain data and share NFT dashboards. It takes more work, but anyone can check your method. Nobody outside CryptoSlam can check its method.

SlamNet and the SLAM token: what happened

In July 2024 a Cayman Islands body, the SLAM Foundation, announced SlamNet. It was pitched as "the information economy of Web3". CryptoSlam was its main data supplier. Animoca Brands designed the token model.

The plan had several parts. SlamLink would pipe data to apps, and SlamChain would be a place to trade. SlamX would host community writers. A .slam NFT and a SlamNet DAO would run governance. The SLAM token was due "later this year", meaning late 2024.

As of October 2026 we found no sign that the SLAM token ever launched. The SlamNet website returned a server error when we checked. The @slamnetxyz X account had posted nothing in the past 90 days, and CryptoSlam's site footer does not link to SlamNet. Treat SlamNet as stalled unless CryptoSlam says otherwise. Be wary of anyone selling a "CryptoSlam token".

CryptoSlam founder, funding and history

Randy Wasinger, a lifelong baseball card collector, built the first version in 2018. It tracked MLB Champions, an early NFT game on Ethereum, according to Startland News. The site then grew to cover more collections and chains, as NFTs spread from games into art. The company is based in Overland Park, Kansas.

Mark Cuban put money in in April 2021. Nine months later, CryptoSlam raised a $9 million seed round led by Animoca Brands. Cuban came back in, along with Polygon and others. Reid Hoffman of LinkedIn and Mark Pincus of Zynga were among the angel backers. Cuban said then that CryptoSlam had become "the de facto source of information and pricing on all things NFT".
