Our startup was selected for Web Summit Rio 2026 after years of building an offline-first financial infrastructure

After years of building, late nights, setbacks, and countless iterations, our team was selected to showcase GhostPay Mesh at Web Summit Rio 2026.
GhostPay Mesh is an offline-first infrastructure designed to orchestrate cryptographic transfers even when internet connectivity is limited, unstable, or temporarily unavailable.
What started as an idea around resilience, connectivity challenges, and financial infrastructure evolved into something we were finally able to present to founders, investors, partners, and visitors from around the world.
This photo represents much more than a startup booth.
It represents years of work, persistence, learning, and a team that never stopped believing in the vision.
A huge thank you to everyone who stopped by our stand, shared feedback, challenged our assumptions, and helped us think bigger.
The journey is still just beginning.
🚀 Web Summit Rio 2026
🌎 Building infrastructure for a more connected world — even when connectivity isn't available.

I built a Splitwise for Solana and just launched on Seeker

I just launched SplitSOL, a group expense splitting app for Solana users. Think Splitwise but you actually settle debts with USDC on-chain instead of just tracking them.

What it does:

  • Split expenses equally, by exact amount, or by percentage
  • Settle up instantly with USDC
  • non-custodial, you sign in with your own wallet
  • Send USDC directly to friends peer-to-peer

Built this solo from scratch.
Would love honest feedback from anyone who tries it.
Currenlty the app is live on the solana seeker

Built an AI-powered crypto wallet risk scanner. Looking for feedback.

Hi everyone,

I’ve been building AICryptoShield, an AI-powered crypto wallet risk scanner.

Users can scan a wallet address and receive:

• Risk score
• Wallet intelligence report
• Blacklist and sanctions checks
• Suspicious interaction detection
• Monitoring and alerts (currently being added)

The goal is to make wallet due diligence simple for everyday crypto users.

I built the project using AI and no-code tools and would love honest feedback:

• Would you use something like this?
• What features would make it more valuable?
• What would stop you from paying for it?

Thanks for any feedback.

Is Web3 still a good domain to consider?( like in terms of dApps and Smart contract development

I have just started learning web3, note that I am complete beginner to this field, currently starting to learn solidity for smart contract development and I have just finished learning JS(like all the concepts OOPs, Asyn/Await, promises) and also parallelly learning Typescript. So my real question is because claude just deployed fable 5. Am I going on the right path or this web3 developing will also be vanished in near future because of AI domination?? Also if yes is there any other career path to achieve in web3??
