HackMol 7.0

TerraHack 2026

BuildfestKashmir

Privacy is one of the cornerstones of web3. In this spirit, we welcome hackers to develop innovative solutions to bolster privacy for ethereum applications and platforms.

Privacy

Best Project

Simplified transactions to bolster crypto utility can be a key catalyst for adoption. Hackers are encouraged to think beyond the boundaries of TradFi and explore new financial possibilities.

DeFi

AI is changing the way we build and use applications, and when combined with blockchain, the possibilities multiply. Hackers are encouraged to explore how intelligence can be built into onchain systems, making them smarter.

BEST project during the hackathon based on unique use case, creativity in idea, and demo.

BEST Overall Project

Build a privacy-preserving application on top of BitGo's wallet infrastructure.
Using BitGo's SDK and testnet, you can create wallets, generate fresh addresses per transaction, build and sign transactions programmatically, enforce policies, and leverage webhooks. This could be a stealth-address payment system that disburses funds from a BitGo wallet to unlinkable recipient addresses, a ZK-proof layer that gates access to DeFi protocols without revealing the wallet owner's identity, private multi-sig governance where signer votes stay encrypted until threshold is met, or any creative approach to on-chain privacy built on BitGo wallets.

Best Privacy Application using BitGo

First Prize

Second Prize

Build a DeFi application that leverages BitGo's wallet infrastructure to bring institutional-grade security to on-chain finance. 
Using BitGo's SDK and testnet, you can create multi-sig or MPC wallets, build and sign transactions programmatically, enforce policy rules (spending limits, whitelists, approval workflows), connect to DeFi protocols via WalletConnect, and set up webhooks for real-time notifications. This could be a policy-governed yield strategy that auto-rebalances across lending protocols, a multi-sig treasury manager for DAOs, a staking automation tool, or anything else that combines DeFi composability with BitGo's enterprise-grade controls.

Best DeFi Application using BitGo

ENS is often thought of as simple name <> address mapping, but really its much more flexible! Names can store arbitrary data via text records, decentralized websites via content hash and more.
This prize goes to the most creative application of ENS in DeFi. This could be some sort of swap preferences stored in text records, DEX contracts that are named via ENS, decentralized interfaces or anything else.

Best creative use of ENS

Third Prize

Any type of ENS integration is eligible for this pool prize, split evenly among all eligible projects. Get creative!

Best Use of Elsa x402 and Elsa OpenClaw skills

Use Fileverse API to create privacy-first apps where users can collaborate with humans and agents without surveillance, middlemen, lock-in.

Build What Big Tech Won't

• AI agents with onchain economic identity: agents that hold wallets, earn, spend, and settle in stablecoins autonomously
• Agentic commerce infrastructure: tools that let AI agents pay for services, APIs, and data via HTTP-native payment protocols (think x402-style)
• Agent-to-agent coordination: multi-agent systems that coordinate tasks and share economic value onchain
• AI-powered DeFi interfaces: agents that research, execute, and manage DeFi positions on behalf of users


AI × Onchain

• Undercollateralized or reputation-based lending: move beyond overcollateralized loans; bring credit risk onchain
• RWA perpetuals and synthetic markets: perp exposure to equities, commodities, treasuries, or exotic assets
• Prediction market infrastructure: trading terminals, liquidity primitives, or resolution mechanisms for prediction markets
• Stablecoin innovations: novel yield-bearing stables, programmable payment rails, or stablecoin-native financial products


DeFi 2.0 - New Primitives

• Private transaction rails: shielded transfers or confidential payment channels for stablecoin/token flows
• ZK-based compliance tools: prove regulatory compliance (KYC, accreditation, jurisdiction) without revealing identity
• Confidential DeFi: private order books, hidden position sizes, or sealed-bid auction mechanisms onchain
• Privacy for AI agents: agent transaction privacy so autonomous systems can operate without being front-run or tracked
• Selective disclosure primitives: ZK proofs that let users share only what's necessary (e.g. "I'm over 18" or "I hold >$X") without full data exposure
