【Selected ChainNews】Carefully selected at the hackathon, these DeFi experiments are most worthy of attention.

Roaming the ETHGlobal hackathon, searching for the next DeFi unicorn.

By: LeftOfCenter

One month ago, the ETHGlobal hackathon launched the 30-day virtual hackathon "Hack Money." Over the past 4 weeks, a total of 300 developers spontaneously formed teams for HackMoney, iterating on ideas, resulting in 118 hackathon projects.

Currently, ETHGlobal has entered the online judging phase.

As the first online "DeFi hackathon," HackMoney is designed for hackers worldwide to build DeFi applications. Given that many phenomenal projects have emerged from hackathons—such as the beloved Uniswap—and with DeFi being the hottest term in the cryptocurrency world, HackMoney is worth close attention.

ChainNews carefully reviewed over a hundred projects participating in HackMoney, selecting some inspiring projects and applications to introduce to everyone.

We hope that the projects selected by our discerning eyes below can inspire decentralized finance practitioners or help cryptocurrency investors discover opportunities.

This feature, submitted by Zapper.fi, allows liquidity providers to seamlessly rebalance their funds distributed across various DeFi protocols. Through the Pool Pipes dashboard, users can easily switch between Uniswap V2, Curve, Balancer, and dozens of other liquidity protocols set to go live in the coming months (such as FutureSwap and Shell) with a single click, reducing the need for multiple steps and thus lowering gas costs and minimizing slippage.

Furthermore, these operations can be further customized by programming Zapper to meet specific investment criteria, such as triggering rebalances and liquidity transfers based on incentives, pool sizes, and pool shares.

It is worth mentioning that Zapper.fi is the result of a merger between DeFiZap and DeFiSnap, aiming to make DeFi more accessible to non-technical users. The merged Zapper.fi will become a new asset management platform offering a range of new features, including Multipooling and Zips.

This is a decentralized application based on AMM that proportionally distributes ownership of NFTs, developed by Mick de Graaf. What the Frac allows the tokenization of shares in NFT auction proceeds.

The What the Frac ecosystem has several roles, including NFT sellers, NFT fractional buyers (primarily speculating through partial purchases), NFT buyers, and Keepers. Users distribute these tokens using Balancer, initiating a fund pool requiring only 2% of the DAI value of the NFT. Initially, the pool consists of 2% DAI and 98% other tokens, transitioning gradually to the reverse, 2% other tokens and 98% DAI.

Clearing of NFTs is conducted through English auctions. Upon auction completion, Keepers are incentivized to claim profits from NFT fractional holders. What the Frac is currently running as a proof of concept on Rinkeby.

Developed by Ethereum scaling solution Matic engineer Arpit Agarwal. As a stablecoin index, DefiDollar maintains a USD peg by adopting DeFi primitives and subsidizing collateralization ratios.

DUSD achieves stablecoin hedging, offering a more stable alternative with minimal governance. Currently, DAI, TUSD, and MKR (converted to underlying assets via Uniswap V2) are used to create DUSD.

DeEd is a decentralized education platform built on smart contracts and DeFi tools, short for Decentralized EDucation, where student tuition fees are deposited into the course's fund pool. This fund pool utilizes interest and revenue rewards generated from various DeFi applications to support students in their studies.

Additionally, the better a student performs, the larger the share of returns the teacher receives.

Each course's fund pool is operated by a fund manager, who can be a professional or a smart contract, deciding how to invest these funds, such as providing liquidity to Uniswap, or investing in Aave or Compound lending protocols to generate stable passive income, or even attempting riskier leverage operations by borrowing tokens from Aave and Compound.

With this platform, anyone can create online schools, customize them as charitable organizations or for-profit entities, configure university discounts, donation parameters, and student scholarships.

Introduction Document

Providing stable annual rates for liquidity providers through hedging three protocols, without experiencing impermanent losses due to arbitrage.

Specifically, the DAI ETF creates Balancer pools for three tokens— aDAI, cDAI, and DyDAI— with a 33% weight allocation each. When users provide liquidity to this pool, they receive a Balancer liquidity token, meaning liquidity providers hedge DAI interest across Aave, Compound, and dydx.

The main highlight of this application is: No impermanent losses due to liquidity provider arbitrage.

Currently available for testing on the Kovan testnet. In the future, this ETF will support CHAI and DDEX interest-bearing tokens, dynamically changing rates based on rate differentials by creating private pools. If there is sufficient liquidity, the ETF may be added to Uniswap for trading against DAI.

LiquiDeFi aggregates Dai funds from users to provide liquidity to liquidation bots on the mainnet, currently only supporting Aave.

Users depositing Dai receive newly minted sharkDai, allowing users to share profits from liquidation bots proportionally based on their liquidity pool share.

Liquorice Gen is a liquidity generator allowing users to easily create dynamic bonding curves, aggregate liquidity, and launch tokens on the mainnet without going through traditional fundraising routes.

By using automatic market-making with bonding curves, users can deterministically increase collateral, thereby setting a price for token issuance on the Uniswap market.

cChannels allow users to earn interest when making off-chain payments. These are a series of payment channel contracts supporting Ethereum and ERC20 payments. When funds are deposited into cChannels, the funds are subsequently sent and locked in Compound, continuously earning interest for the depositor while supporting off-chain payment spending.

Additionally, users can add more funds to the contract and even recharge the channel with different collateral supported by Compound, such as borrowing DAI with ETH collateral to recharge a DAI cChannel.
