On-chain sponsored banners that reward viewers in WETH for verified visibility.
Gloam is the privacy layer for Robinhood Chain. Shield a balance, then hold, pay, and send tokenized assets without exposing your size or holdings. Settlement stays verifiable to anyone who needs it.
AgentGuard VerifyPay is a policy-controlled escrow layer for autonomous AI agents on Arbitrum. It lets a Buyer Agent hire a Seller Agent within explicit budget, asset, risk, and expiry rules. Quotes that violate policy are BLOCKED, invalid results are FROZEN, and payment is released only after independent verification with publicly verifiable evidence.
Apraxus is blockchain infrastructure for the autonomous economy, enabling autonomous agents, programmable payments, and machine-to-machine transactions through EVM-compatible infrastructure and developer-focused onchain tooling.
Social forum where verified people connect in a safe and authentic context.
Megawatt is an RWA protocol that lets onchain capital finance utility-scale solar and battery storage across Central and Southeast Europe, with the energy revenue those assets generate routed back onchain as yield to depositors. The problem is capital, not capacity. Gigawatts of permitted, ready-to-build solar and storage sit unfinanced because mid-scale projects fall between infrastructure funds, whose ticket sizes push them toward much larger assets, and local banks, which remain cautious on hybrid solar-plus-storage revenue. Meanwhile, onchain capital sits in low-yielding financial instruments with almost no access to real assets. For the Buildathon, I am deploying Megawatt on Robinhood Chain: pool contracts handling deposits, yield distribution and redemption, plus a transparency layer that publishes verified production and revenue data from the physical assets onchain. Energy infrastructure is illiquid, and nobody exits a battery site the way they exit a token, so continuous verifiable performance data is what makes an investor willing to hold it. No token, no emissions. Real revenue from physical, insured assets.
A decentralized dispute resolver powered by GenLayer's AI consensus. Three AI agents (Client Lawyer, Freelancer Lawyer, Neutral Judge) analyze the evidence and reach a verdict.
Fully Self-Custodial AI-Native Onchain Hedge Fund Manager with AI-curated Vaults
Stake, borrow against your stake without unstaking, and put the loan to work in hourly markets, with settlement anyone can verify.
EQLTY is a verifiable decision layer for tokenized stocks on Robinhood Chain, an Arbitrum Orbit network. A private fleet of AI agents researches the market, challenges recommendations, applies user-controlled ENS rules, and produces an auditable decision before any capital moves. The user approves every trade, while an onchain vault enforces spending, slippage, and deadlines. Uniswap executes the swap and onchain evidence verifies the result. EQLTY makes AI-assisted investing transparent, non-custodial, and accountable.
