Thin Mint allows users to create alternative visualizations for NFTs. This allows users to extend the intellectual property representation of NFTs. For example, a Bored Ape could have a Halloween version or a Decentraland skin that can be used in the metaverse. The Thin Mint NFT by default is connected to the root NFT. Only the root NFT’s holder can mint the Thin Mint. When the root is transferred, so are any alternatives. However, an owner can choose to disconnect these assets later.

ArGoApp is a deployment aggregator platform for decentralized cloud protocols, which helps developers easily deploy their static websites on Decentralised Protocols. The developer doesn’t need to download anything, they can just come to our platform (https://app.argoapp.net) and connect with their GitHub account. We automatically fetch all the repositories from the user's GitHub account. Users then select which repository they want to deploy and choose the protocol (IPFS, Filecoin, Arweave, Skynet, etc). Users just have to fill the deployment configurations and click on Deploy and that's all. It will be up and running on the chosen decentralized protocol. Users can also connect centralized and decentralized domains (like Handshake, ENS) from our platform with just some clicks. Users can also automate their deployment as well which will increase their productivity when building their application. Currently, we support JavaScript app frameworks like React, Vue, Next, etc, but more Jamstacks will be added as we grow. Users can pay us in one-time fees, they can also opt for subscriptions as well, which have some added features.

La Vie is a game & a gamified savings account. Turning the traditional model of in-game micro-transactions on it head. Instead of paying more for exclusive items and character upgrades, in La Vie players are required to stake to get these perks. The intent is to help people save more by staking into time based Certificate of Deposits or Savings Account, which will earn them a passive yield.

All accounts and in-game items are trade-able Non/Fungible Tokens, which will help our players  add additional value to their wallets. 

La Vie will also help the creator economy by incentivizing third party creators to create customized in-game items for a royalty fee for every trade.

Our current project is to find viable ways of upgrading already-decentralised projects such as open source games to blockchain-powered projects, with the objective of better allocating resources & time spent so as to improve the viability of the project as a whole. In particular, we're looking into integrating viable, closed-loop tokenomics to leverage the 'player time spent' to reward content creators in a decentralised manner.

We're currently targeting the popular rythm game Osu!, where some 'enabler' tasks (moderation, content review) are not productive enough for a lack of incentive. Using real-money (via ETH) to increase the attractiveness of these tasks would generate positive externalities in the ecosystem that could increase value overall.

We believe we can work on implementing strong tokenomics as an option on the game to add the following features:
- reputation system based on authenticated proofs of plays, verified by other players,
- anti-cheating system through consensus on leaderboards and said proofs of plays,
- NFT marketplace to buy & sell maps with an incentive mechanism to pay moderators,
- incentives for developers to build new features with voting from the community.

We're looking to build this for non-crypto people, therefore focusing on ease of use and core mechanics.

This project allows any user to stream tokens to any supported DeFi protocols (such as Aave, Balancer, dHedge etc) in an automated fashion. The aim is to let anyone create a solution for interacting with any DeFi protocol. People/devs who create these solutions can get rewarded for the same. Currently, the core devs (us) can only make these solution contracts but the ultimate goal is to make this permissionless. We have integrated Aave protocol and partially integrated Balancer protocol (front-end isn't ready for it). We plan to use various other protocols too in the future after thorough testing of the contracts.

Project Vinland is an onchain metaverse game in which users, when signed in by their Metamask/wallet, can tour the DeFi metaverse which has multiple stores/avenues like Aave and  Sushi to make transactions. This gamified visual experience will allow new users to better comprehend the difference between these dapps and their IRL counterparts.
Like AAVE -> Bank and Sushi -> Binance/CEX . 
Imagine a world where you can play to earn in a battle royale game betting on your skill , then swap the same crypto winnings in the metaverse itself .Then visit your NFT museum to witness them in full 3-D glory . All in a trustless ,decentralized manner ,just using your crypto wallet . No email , no dox ,just plain simple AAA gaming experience .

Eth Moji is a KaoMoji-based NFT community. NFTs are first proposed via DAO. In order to send a proposal the user would need KAO tokens that can be swapped. Once a proposal is created it can be approved or rejected. If approved, it would be converted to an auction in which users bid KAO tokens to get the freshly created NFT. The KAO tokens from the winner bid would be split in two, one to the proposal creator, and the second one to be burnt.

This project is a very simple front end interface built on the existing StandardBounties protocol. We make it easy to create a bounty with an ETH reward. When it's created, the issuer can share that bounty page with anyone (e.g. in Discord, Twitter, Telegram). Anyone who is interested can add their entries to that page (only visible to the creator of the bounty). The bounty issuer can easily view and choose to accept any submissions.

USA Wallet will be built to "Simple, Safe, and Secure" on-board US no-coiners to crypto.  Friendly assistants will guide users along every step of setup and use.  Token balances will be displayed and users will be able to buy, send, and swap crypto.

Previous version of USA Wallet was a web dap.  This version will be deployed as mobile aps on iOS and Android.  Additionally a utility token will be deployed.  Ownership of the utility token will lower transaction fees and unlock early content and advanced features in the mobile dap.

Our dApp that allows people to see the chances of having a DeFi loan liquidated on any given day as well as see the relationships in price movements across tokens. We have include an innovative technique for fitting historical data into tiny probability distributions called 'chance-data' that may be used by smart contracts, trading bots, AI models and even spreadsheets. Chance-data has a special property that normally probabilities do not have when used in decentralized environments- they can roll-up risks and opportunities. Decentralized simulations historically are not additive. These simulations are that means they may be audited and used to rollup risks. This is a way for protocols to show systemic risk too and get ahead of any regulators. Special note we are 5 strangers the youngest 15 years old. We are located in 4 different countries and 5 different time zones. The entire project was done without any verbal communication, no set meeting times, and no burn down task lists. Good fun.

The Rhada Protocol operates as an event-payment-streaming service for open-source projects, primarily DAO's. The protocol measures the contributions of members of a DAO using metrics from external API's such as GitHub and Discord. DAO's have the ability to set individual parameters on what is considered to be a "contribution" and how those tasks are valued. Each active member of a DAO is compensated via a payment streaming service with a fluctuating stream that sends a set amount of currency per second. This value is derived from the various contributions specific to each member.
    With the Rhada Protocol, our team hopes to provide fair rewards to developers working on open-source projects and a more efficient means of handling payouts in vote-driven entities such as DAO's.
Due to time constraints for the Hackathon we focused on a simpler method to enable DAOs to split salaries between their members based on round voting.
After a DAO registers for the protocol, members may apply to become contributors and input their Discord and GitHub handles into the system. Upon a DAO-specific approval method, users will then be able to participate in voting rounds, wherein users will vote on contributors based on the “contribution” (as defined by the DAO) the user made in between rounds. After a voting round is closed, by an admin or after a period of time, the salaries are given to the DAO members proportionally to the votes they received using Superfluid Payment Streams.

A problem facing DeFi today is that borrowers, debt holders, or users who take loans are at risk of losing their collateral due to liquidations which occur when the health factor of their portfolio drops to below 1. 

Because of the volatility of crypto markets today this makes it difficult to know in advance when that will occur, only that it is inevitable given the unpredictable nature of crypto markets today. 

Although this is not a new problem, from the research we have done during this hackathon, this problem still lacks a long term solution. We wish to offer a solution that can support this goal of increasing user adoption into the DeFi ecosystem by mimising risk new users. We do this by making our UI extremely simple, friendly, and straightforward to use so that new users will know exactly what they are getting themselves into. 

The fact is that liquidators are incentivised to repay undercollateralised positions because of the discounted collateral and bonuses they will earn by doing so. 

While, flash loans historically has been used as a tool for gain, undermining, and attack, we feel that in the right hands, they could also be used as a force for good by allowing us to repay borrowers outstanding debts and returning collateral to them without making them just another liquidation statistic. 

We want to be part of the solution. We hope that by using Chainlink Keepers or perhaps more cost effectively running our own Keeper Node to monitor the health factor of DeFi users who subscribe to our platform, their health factors can be regularly monitored and corrective action be taken before it is too late. 

One of the challenges that has yet to be addressed is the unpredictable nature of network congestion and gas price fluctuations that may sometimes lead to the failure of oracles, keepers, and lending platforms from being able to find liquidity when it is most needed as we have seen with the market crash on March 12, 2020 and how it impacted Maker. That is why we feel that if we are unable to predict when such market events or flash crashes will occur at least there could be mechanism in place to minimise losses for users new and old.

MillionDollarTokenPage (MDTP) is the web3 version of the web2 site milliondollarhomepage.com from 2005.

In the original people would buy and set the pixels as a one-shot process. However, now with NFT technology users can actually buy that space, update it as often as they like, and re-sell later if they wish. This allows for a whole new way of interacting with the site that can generate its own economy and we view as something similar to Decentraland or Cryptovoxels but in 2D, ie. a 2D metaverse

MDTP is the place to show off and share what's hot in crypto and NFTs, in a space that you yourself own as an NFT! MDTP is set to become the Homepage of the Metaverse. Come own a piece of crypto history!

In music, sampling is the reuse of a portion (or sample) of a sound recording in another recording. Samples may comprise elements such as rhythm, melody, speech, sounds, or entire bars of music, and maybe layered, equalized, sped up or slowed down, repitched, looped, or otherwise manipulated. Sampling is a tedious and manual process for producers because separating audio isn’t the easiest or most streamlined thing to do. Stems in music are packaged groups of multiple tracks that have been layered together. For example, a snare drum sound is a single track while a recording of an entire drum kit is a stem. Another is a single electric guitar track while four or five guitars are layered on top of one another in a stem. Independent artists can release stems and samples with a license that works for them and the purchaser. With a platform like this artists can share their samples with other artists or their fans and then can earn royalties on it. The people who buy the rights to this sample can then use it in their new songs or just keep it as a token.

Aside from the technical aspect, the sampler can run into legal issues due to licensing. Independent artists can release stems and samples with a license that works for them and the purchaser.
