HYCHAIN

HYCHAIN is a gaming-focused Ethereum layer 2 built on Arbitrum Orbit with an AnyTrust design: transaction data is held by an external data-availability committee in exchange for lower per-transaction cost and steadier block production, with network fees denominated in TOPIA. Its main workload is HYTOPIA, a voxel-style building and exploration game that began as NFT Worlds. The team also folded in MetaFab, an open-source Web3 game backend, so outside developers can call account, item, storefront and payment modules directly.

For developers the point is putting chain, assets and game backend into one toolkit: studios skip building their own wallet stack and marketplace, because item minting, marketplace fees and player accounts settle on the L2 while the base chain carries finality. Community operators run the node set and receive a share of network fees, so chain and game share one infrastructure layer, with registered games already in four figures.
