📈 Key Themes of ETHOnline 2024

Several key themes emerged from the ETHOnline 2024 project submissions, best exemplified by our finalists:

Hypertui embodied the push for better developer tools, enabling devs to easily query and analyze on-chain data. AuthWallet 2.5 also fell in this category, simplifying wallet UX with Web2 primitives.

OnlyCars and Membrane Finance innovated in DeFi and payments. OnlyCars enables a decentralized EV charging network with crypto, while Membrane Finance allows cross-chain lending with Ethereum NFT collateral.

Eros, SignCast and Viral.games represented the rise of social and gaming applications. Eros provides privacy-focused dating, SignCast enables exclusive content monetization, and Viral.games gamifies viral predictions.

Capture the Prompt addressed privacy and security, gamifying AI prompt robustness.
