In the past week, Polygon-based NFTs experienced a notable increase in sales volume, overtaking Ethereum. The surge was largely influenced by Courtyard, a platform that turns physical collectible cards into digital assets.
Polygon Leads Weekly NFT Sales
As of April 22, data shows that Polygon NFTs reached $22.3 million in weekly sales volume, climbing to the top. This figure represents 24% of the total $92.9 million NFT sales recorded during the same period. Additionally, the number of NFT buyers on the network jumped by 81%, surpassing 39,000.
Ethereum came in second with $19.2 million in weekly NFT sales. Mythos Chain followed with $14.3 million, and Bitcoin-based collections ranked fourth with $14.1 million in sales.
Tokenized Physical Cards Boost Polygon Activity
The rise in Polygon NFT sales was primarily driven by a real-world asset (RWA) collection. The RWA model involves tokenizing tangible assets—such as art, real estate, or collectibles—on the blockchain, increasing accessibility and tradability.
According to data, the main driver behind the surge was the Courtyard NFT collection, which generated $20.7 million in sales, outperforming other leading projects.
Courtyard is a digital marketplace that focuses on graded physical card collections, including Pokémon, basketball, and baseball cards. These cards are stored and insured in a vault managed by a security company, meaning the NFTs are physically backed. Buyers can choose to redeem the physical card by burning the NFT, which permanently removes it from circulation.
On-Chain RWAs Become a Strong Narrative in 2025
In Q1 2025, on-chain RWA projects have gained serious momentum. Data from RWA.xyz shows that tokenized assets have reached a total value of $21.2 billion, excluding stablecoins. The current stablecoin market cap stands at $227 billion.
These developments signal a clear shift in the market, marking the strengthening connection between physical assets and digital ownership in both the NFT and RWA sectors.
