HiveBits

RWAs, Consumer Apps

Bees pollinate over 75% of global crops, and pollination alone is a $10B industry. Honey, propolis and bee venom fuel cosmetic and pharmaceutical markets worth over $60B. In the meantime, beekeepers lose around 40% of their hives every year. Pesticides and poor land practices are wiping out colonies faster than they can recover. HiveBits turns real bee farms into digital assets that anyone can co-own. Our smart hives generate measurable returns from honey and pollination while helping restore bee populations. We’re beekeepers and developers who’ve generated over $175K in revenue by delivering bee products and apitherapy treatments to more than 4,000 people.

Hobba

DeFi, Consumer Apps, Stablecoins

Hobba – self repaying loans Hobba makes borrowing safe, efficient, and effortless. It automatically routes liquidity across Solana to secure the best rates, generates yield on idle capital, and uses that yield to pay down users loans over time. If collateral rises, Hobba accelerates repayment, if it drops, an off-chain risk engine rebalances positions to keep users safe. Capital that never sits idle, and loans actively repay themselves. The same engine powers our on-chain BNPL layer - letting users split real-world payments while their crypto keeps working - OPOS Borrow better.

Honoris

DeFi, RWAs, Infrastructure

Revolutionising Internet Capital Markets on Solana Traditional fundraising often leaves investors with only paper gains, while startups miss out on trading fees and face impermanent loss risks. This leads to volatility, shallow liquidity, and broken incentives — resulting in failed projects and lost capital. Honoris solves this by introducing a standalone Anchor module that creates “honorary” LP positions in Meteora DAMM v2 pools. These accrue quote-only trading fees (e.g., USDC) with zero IL exposure, distributed pro-rata via Streamflow to investors based on their locked balances. How it works? > Startups initialize PDA-owned positions; fees accumulate from pool trades; daily cranks distribute rewards — 90% to investors, 10% to creators — using on-chain pagination for scalability and transparency. Impact: Aligns incentives, boosts liquidity, and builds trust by turning speculative tokens into real yield-bearing assets..
