A look at the 13 winning projects from the ETHGlobal Amsterdam Hackathon
By Karen, ForesightNews
From April 22nd to 24th, ETHGlobal held the ETHAmsterdam offline hackathon in Amsterdam. Sponsors including Optimism, Mina, Polygon, WalletConnect, Livepeer, 1inch, SKALE, etc. provided a total of more than 400,000 US dollars in bonuses to attract Developers use their network or technology to build.
Among the 13 winning projects announced by ETHGlobal last night, there is Retr0x, a funding application that separates retrospective and future regeneration funds on Optimism, Democrazy, a tool that supports anonymous governance voting through zero-knowledge proofs, and cross-chain debt made by the Fuji Finance team Migration application Tempra and the "burn after reading" platform Tempra on the chain, etc. Generally speaking, there are many donations, DAO tools, and projects aimed at lowering the threshold of Web3, and they are mainly built on the Optimism and Polygon networks.
Retr0x: A Retroactive Regenerative Public Good Funding Application on Optimism
Retr0x is a retro-generative public good funding application deployed on Optimism, aiming to combine retro-generative and regenerative funding of projects into a single protocol in a way that most incentivizes work to grow. Once the allocation of funds has been determined, the retroactive portion of the funds will be delivered to self-serve recipients in one go, while the regenerative portion of the funds will be distributed periodically over a set period through Superfluid.
Nimi: The built Web3 personal page can be deployed to the .eth domain name
Nimi will allow building Web3 profile pages and deploying them to .eth domains. Specifically, Nimi combines ENS, IPFS, and Lens to make it easy for users to host content on their ENS domains.
Hexagons Protocol: Building Social Media-Driven Smart Contract Protocols and Frameworks
Hexagons Protocol said, “Once users link their social media accounts (including Twitter, Lens, Discord, etc.) threshold."
In terms of implementation, the Hexagons Protocol framework consists of a Solidity library (implementing hooks-logic and basic interfaces) and off-chain components for interacting with oracles and social media platforms.
Democrazy: Anonymous voting
Democrazy will support privacy-protected off-chain governance voting through zero-knowledge proofs. Individual votes will be encrypted and only the total result will be displayed.
FLOAN: Cross-chain debt migration
FLOAN will allow users to transfer their debt positions (including collateral and debt) to other protocols on other chains with one click. The FLOAN team is mainly several members of Fuji Finance, a DeFi lending aggregator on Fantom, including co-founders and smart contract developers. FLOAN has also received bounties from Connext Network and Aave Grants.
FLOAN said that there will be a Teleporter contract on each chain to hold liquidity to repay user debts. In addition, FLOAN will use Connext to help bridge assets. The specific workflow is:
Teleporter repays user loans;
Teleporter withdraws user collateral;
User collateral is bridged to another chain;
Collateral is deposited on the new platform;
Use collateral to access assets;
Liquidity is provided back to the pool using borrowed assets.
Tempra: On-Chain Instant Messaging Platform
Inspired by Snapchat, the ephemeral photo-sharing app, Tempra lets you upload photos and videos, or privately message friends, but the content becomes inaccessible after a certain amount of time.
Tempra combines Lens Protocol with Lit Protocol and Livepeer, and deploys them all on Polygon Mumbai. Among them, the short-term accessibility of content is realized by customizing the updatable Lit Protocol, which can limit users to view information after a certain period of time.
PFPnative: Quickly launch and distribute the PFP family
PFPnative is a no-code tool deployed on Optimism that allows anyone to quickly launch and distribute PFP generation series, and also set minting prices to fill coffers.
DAOra: Project Management and DAO Analytics Tracker
DAOra is a DAO task management and analytics tracker that will allow users to track tasks across DAOs and earn contributor rewards. Anyone holding DAO tokens can create new tasks and post bounties, and when tasks are completed, other DAO members can vote on the submitted proof of completion. The DAO Analytics Tracker can also measure the engagement of members who hold DAO Social Token rewards via Scatter Score.
Yieldgate: Donate proceeds from staking MATIC tokens to creators or projects
Yieldgate allows anyone to easily stake MATIC tokens and be able to donate proceeds to their favorite creators and projects. Of course, users can also withdraw their MATIC tokens at any time.
Detris: NFT Tetris Game
Detris is an NFT puzzle game project. Users can first cast an NFT and then go to play Tetris. After the end, they can cast the puzzle process into an NFT on Optimism.
Activitydao: Facilitates the creation and operation of activity sub-communities
Activitydao attempts to implement a costless DAO to facilitate the creation and operation of sub-communities around activities.
Activitydao plans to improve DAO by implementing the following operational functions:
Allows free and fast joining of the DAO community around events;
DAO communities can be created around events;
As a community of DAO members, you will be able to vote on upcoming events and also propose new events.
In this process, Activitydao allows users to participate in DAO by staking a certain amount of tokens. If someone does not participate in the activity of pledging tokens, they will lose this part of tokens, and these tokens will actually participate in the activity. Share among people.
Creatorsight: Helps creators analyze collectors
Creatorsight is a platform built for Web3 creators that helps creators analyze and understand their favorite address data, including top favorite addresses, average NFT holding time, and more.
Collective Action: Peer-to-peer donation platform
Collective Action is a decentralized donation platform. Donors can create a prize pool of specified tasks that others can complete and upload proof of, or donate to. Contributors will receive 1 CoAc token for every 1 MATIC spent.
In addition, the prize pool is staked on Aave to earn interest on MATIC, thereby earning profits for the platform. Collective Action does not charge users.
other
Of course, there are many sponsors who also provide bonuses for projects that utilize their protocols, networks or technologies. For example, in addition to the above-mentioned Yieldgate and FLOAN, Aavegotchi card game Aavegotchi-TT and ZK proof cross-chain bridge Zk have also received bounties from Aave -maia.
Among them, Aavegotchi-TT allows users to bet DAI and use their Aavegotchis to play against each other. The bet DAI will be put into the Aave deposit vault, and the winner can win twice the betting funds and the income deposited into the Aave deposit vault.
Built on Polygon, Zk-maia allows users to transfer their assets at low cost and earn interest in the process. Zk-maia uses Tornado.Cash to add two income functions and the Connext cross-chain function to its application. It will lend all the ETH deposited by users to the Aave protocol to earn income, and encourage users to keep their funds in the application for a long time
