Monster
@mnstrGacha platform for tokenized graded Pokémon and One Piece cards on MegaETH, with on-chain pulls and an 85–95% instant buyback.
MegaETHOverview
Monster (mnstr.xyz) is a gacha-style platform for tokenized graded trading cards built on MegaETH, a high-performance Ethereum-aligned chain. Users open digital packs to pull real, vaulted graded cards (PSA, CGC, BGS), with each pull settled on-chain and paid in USDm (MegaETH's native stablecoin) or by credit card. Monster publishes a live expected value and full per-tier odds for every pack, and offers an instant buyback so pulls can be sold back for liquidity rather than shipped. Since migrating to MegaETH mainnet in April 2026, the platform has crossed $5 million in volume and generated over $400,000 in fees, making it one of the leading on-chain gacha experiences.
How It Works
Each pack lists a price, a live expected value, and a rarity distribution (Common → Legendary) with the FMV band and probability for every tier. Pack tiers range from Starter ($50) through Premium ($250) up to Ultra ($1,250), payable in USDm or with a credit card. Opening a pack mints the pulled card on MegaETH, backed 1:1 by the physical graded card held in a vault. Holders can keep the tokenized card, sell it back to Monster at the pack's buyback rate (ranging ~85% on entry packs to ~95% on the highest tier) with no time limits, or redeem the physical card. Pack pages surface recent pulls, top hits, and the chase cards available in the pool.
