A collection of 4,500 ‘The Seven Deadly Sins: Grand Cross’ themed NFTs has completely sold out during the NFT Adventure event. Amid declining digital asset trading volumes throughout 2026, Marblex - the blockchain gaming ecosystem owned by South Korean publisher Netmarble - proved that market liquidity has not completely dried up. They completed the mint-out for all asset units, a move documented in a report by BlockchainGamerBiz on July 30.
This achievement builds on the strong appeal of its source material. The hit mobile RPG is directly adapted from the Japanese manga and anime series of the same name, inheriting a dedicated global fanbase. Its release mechanism was also designed differently from traditional asset drops. Through the NFT Adventure format, the platform integrated gameplay elements into the minting process, creating structured engagement for participants. This organized approach reflects Netmarble’s vision, which was previously reported to focus on turning in-game antagonists into interactive NFTs rather than issuing static display images.
Why Did Two Platforms Move Simultaneously?
This distribution wave was not confined to a single ecosystem. A lead report from TradingView spotted similar activity on Immutable - an Ethereum-based blockchain gaming platform - which also launched ‘The Seven Deadly Sins’ NFT Adventure showcase on July 30, 2026. The simultaneous rollout across both platforms points to cross-chain coordination tactics between developers.
As of this writing, there has been no official confirmation regarding the full extent of the partnership between Immutable and Marblex. However, running dual storefronts serves a calculated tactical purpose: the Netmarble channel keeps existing players within its internal ecosystem, while the Ethereum network attracts capital from native Web3 users who frequently trade assets across multiple applications.
Value Retention in a Sluggish Market
The sell-out of Marblex’s 4,500 assets offers a blueprint for navigating cool market sentiment. As collectors increasingly overlook standard generative art collections, projects backed by major intellectual property (IP) effortlessly draw strong market demand. This solid volume is driven purely by players’ emotional connection to the original franchise, curbing short-term speculative flipping by retail traders.
For industry creators, this phenomenon upends traditional standards of project viability. Launching empty artwork backed only by promises of future utility is no longer effective; real value today lies in mature narratives that have engaged their audience from day one.
