Polygon-based non-fungible tokens (NFTs) have dominated the digital collectible sales market in India, experiencing a remarkable 20% surge in the last seven days. Recent data from NFT tracker CryptoSlam revealed that Polygon NFTs surpassed Ethereum in sales, achieving a volume of $22.3 million in the past week, representing 24% of the total NFT sales volume, which stood at $92.9 million. The network attracted over 39,000 NFT buyers during this period, marking an 81% increase from the previous week. Despite this surge, Ethereum held the second position with $19.2 million in NFT sales, followed by Mythos Chain with $14.3 million, and Bitcoin-based collections with $14.1 million. The significant rise in Polygon NFT sales was primarily attributed to a real-world asset (RWA) NFT collection, signaling the integration of the RWA narrative into the NFT space. RWA tokenization involves converting tangible assets like art, property, or stocks into digital tokens on a blockchain, enabling easier accessibility and trading opportunities. The surge in Polygon NFT sales was driven by the Courtyard NFT collection, which recorded a sales volume of $20.7 million, outperforming other popular NFT projects of the week. Courtyard serves as an RWA marketplace for graded physical card collections, including Pokémon, basketball, and baseball cards cherished by collectors. The platform ensures the security and insurance of tokenized cards in a vault operated by a security firm, backing the NFTs physically. Notably, the platform allows users to redeem the physical card associated with the NFT, leading to the burning of the NFT and its removal from the marketplace. The rise of on-chain RWAs has been a prominent trend in 2025, with data from RWA.xyz indicating that tokenized assets have reached $21.2 billion, with over 97,000 asset holders, excluding the $227 billion value of stablecoins.
