Monster (MNSTR) is a MegaETH-based platform where users buy randomized packs that each contain one professionally graded Pokémon or One Piece card, represented as an NFT. Pulled cards are held with third-party vault custodians, and holders can ship the physical slab, trade it on the marketplace, or sell it back at up to 95% of fair market value. Packs can be paid for in USDm or by card.
Monster is operated by Monster Strategy, Inc. and was built by developers who go by andy (@andy8052) and CryptoSamurai, who had previously shipped crypto apps together across several chains. The project launched on Base in fall 2025, originally describing itself as an onchain Pokémon card treasury. It moved to MegaETH after the team concluded Base was not delivering the liquidity, distribution, and speed it needed. Pack odds are published, cards are graded by PSA, CGC, or BGS, and the platform runs a points program with a public leaderboard. Coverage has expanded from Pokémon to One Piece, and sports cards are listed as coming soon.
