Madhav Gupta

Hey, I'm Madhav 👋 - a full-stack Web3 engineer with 3+ years shipping production smart contracts, 10+ international hackathon prizes, and 8 shipped protocols across Ethereum, Solana, Sui, Hedera, and Fuel. I live at the intersection of DeFi infrastructure, AI agents, and prediction-market mechanisms.

Why a hacker house: I do my best work in a room full of builders. I was selected for the Fuel Labs in-person residency in Costa Rica (2025), where I built Reckless AI AI-automated cross-chain DeFi vaults with built-in loss protection. That kind of environment heads-down, in-person, shipping alongside people who are as obsessed as you are is exactly where I want to be.

What I'm good at: taking an idea to real, deployed, on-chain, and defensible solo. Solidity/Move/Sway contracts, Foundry + fuzz testing, and enough AI-agent plumbing to make autonomous systems actually move money safely.

A few things I've built:

• 🥇 Agoric Hackathon 2024 - 1st place.
• Bet-a-Meme (ETHOnline 2024, 2 prizes)= social prediction market bridging real virality to on-chain settlement via Sign Protocol.
• Calibr (HackMoney 2026, Sui track) - a reputation layer that scores judgment quality instead of capital; rewards honest calibration, penalizes overconfidence.
• RUGNOT - an autonomous defense agent that scans tokens through a multi-layer risk pipeline and sells its verdicts to other agents via a paid x402 API.
• MezoShield - a 24/7 non-custodial liquidation shield for Bitcoin-backed loans, reviewed and validated by the Mezo core engineering team.

What drives me: systems that prove themselves instead of claiming it — verifiable, on-chain, re-runnable by anyone. I'd love to bring that to Goa. Let's build. 🛠️
