GLOOOP.FUN

RWAs, Consumer Apps

$23 billion. That's how much money evaporates every year because vouchers can't be transferred, resold, or properly verified. Groupon takes 50% commission and 1 in 5 deals never get redeemed. Glooop flips the entire model: every deal is a compressed NFT on Solana that you own, trade, or resell on a secondary marketplace. Our 3-layer blockchain verification system makes fraud impossible—no fake QR codes, no screenshot scams, no double-spending. Merchants keep 95% of revenue instead of 50%. Minting costs $0.0001 per NFT, not $5. And we've built a public REST API so developers can build price comparison tools, trading bots, and analytics dashboards on top of our infrastructure. This isn't a marketplace—it's a platform. We're proving NFTs can solve billion-dollar problems when they're useful, not speculative.

GoTrade

RWAs, Consumer Apps, Undefined

GoTrade is a Blockchain-Enabled Guarantee of Origin Certificate Trading Platform. Large Energy Users (LEUs) today are pursuing increasingly ‘clean’ sources of energy. A popular product in this domain is the Guarantee of Origin (GO) certificate - An EU wide product that verifies that a unit of power (1MWh) was generated from a particular plant. In the Current market, GO creation and trade takes 4-8 weeks, no correlation with energy consumption & certificates bought, leading to technical & systematic inefficiencies (Greenwashing). The system is inaccurate, misleading with no demand side incentives. GoTrade tokenizes energy using real-time generation data and allows seamless trade via smart-contracts, bringing GO creation to purchase time to 2-4 hours. GoTrade saves time, manual work and compliance risks for consumers while improving ROI for generators. Our goal is to bring the green economy on-chain with Solana and help achieve Europe's ambition of becoming carbon neutral by 2050.

Group Fun

Stablecoins

A Token launchpad with shared fees for telegram group chats

Group Trade

DeFi

A shocking amount of crypto discourse happens on Telegram. In many ways, it is the beating heart of our industry. Telegram is where warm intros happen, friends hang out, and alpha gets shared. We are particularly interested in this last point. Telegram bots were an early example of “turning Telegram into a trading platform” but we think there’s much more to build. Telegram bots are great for single player trading, but have neglected more multiplayer experiences. You could imagine a degen chat on Telegram contributing to a shared pot of money. The capital is then controlled by several members of the chat who have permission to trade. These permissions are programmatic but adjustable – all from Telegram. This tooling turns a groupchat into a gamified hedge fund.
