Hobba

DeFi

Hobba is a prime broker for onchain loans. Users deposit collateral like cbBTC or SOL, borrow USDC against it, and the yield generated by their collateral automatically pays down the loan in the background - often resulting in a negative net borrow rate.

Hoshino

Gaming

Hoshino is a mobile virtual pet game with a strong visual identity, where each season follows the lunar cycle. Most Web3 games are speculation pretending to be gameplay. Hoshino is the opposite: a real game mainstream players want to open daily, where onchain ownership is an upgrade, not a requirement. No token. No P2E. The onchain layer is restrained on purpose, only used where it solves a real problem for the player. This is what Web3 gaming looks like when you build for players first.
