BitGo at @ethmumbai 2026. The best part of a week like this isn't the stage time. It's the conversations you didn't plan for, the teams pulling all-nighters, the community that shows up just because they care. Congrats to everyone who built on BitGo's tracks, especially the winners. India's ecosystem is moving fast, and we're glad to be moving with it. 🤝

And that's a wrap on ETHMumbai 2026. mandal aapla aabhari aahe 🙏

Built MeshSearch with team [object Object] at @ethmumbai 🚀 A private web search layer for humans & AI agents: • ZK-committed queries • No accounts, pay-per-search via USDC • 3-hop ENS relay routing • Encrypted history stored on Fileverse devfolio.co/projects/meshs…

Day 1 wrapped! 🚀 We are team 'VectorFlow'. Building our project and sharing the journey live. Follow along for updates. @jaykerkar0405 @Chirag8405 @CyreneAI @GenesisQuestIT @QuestIT_Vesit #BuildInPublic #GenesisHackathon

Turns out doing things differently works. This one was different on purpose.

Built at ETHIndiaVilla 2025, powered by @devfolio . Team behind VaultID: • @whyash5114 • Sundaram Krishnan

Built VaultID — a decentralized way to make authentication sessions portable. Today, sessions are device-bound, fragile, and tied to insecure cookies. Switching browsers or devices often means logging in again. youtube.com/watch?v=kNMljH…

Hardest challenges weren’t crypto or blockchain. It was detecting login/logout without browser signals, syncing encrypted data from IPFS, and correctly rehydrating cookies with exact browser constraints.

What this enables: • Use the same login across multiple browsers & devices • Share authenticated sessions via a wallet (teams, DAOs, ops) • Single login, usable everywhere No central session store. No plaintext credentials.

VaultID changes that. Sessions are encrypted client-side, stored on IPFS, and anchored with a tamper-proof reference on-chain — with no secrets on the blockchain.

What a weekend! ETHIndiaVilla: you felt like home 🏠

ETHIndiaVilla 2025 was such a vibe. Great hackers, great collabs, and super smooth management by the @devfolio team. Loved the whole experience @ETHIndiaco. Big shoutout to @whyash5114 and Sundaram Krishnan for building this with me. Project: devfolio.co/projects/vault…

So we kicked off ETHIndiaVilla, and it's been nothing but absolute cinema so far ✋🤚
