NFT sales reached approximately $46.78 million in the seven days ending Sep. 12, up 6.8% from the previous seven-day period, according to CryptoSlam data. Ethereum remained the leading blockchain with $16.83 million in sales, although its total declined 6.36%, while Bitcoin sales climbed 50.12% to $9.44 million. The increase came alongside an 84.67% drop in buyer addresses to 41,959 and an 85.13% decline in seller addresses to 43,247, even as transactions rose 48.75% to 917,549. These figures count addresses rather than confirmed individuals. Polygon-based Courtyard led collections with $6.67 million in sales across 104,404 transactions. Bitcoin BRC-20 collections dominated CryptoSlam’s five largest individual sales, which totaled about $4.61 million and included a $2,095,886.72 transaction. The concentration of volume in a small number of high-value trades gives the weekly increase important context.
