The global web3 market has reached record heights with Bitcoin and Ethereum showing a rapid growth of 9200% and 33500% respectively (as per the data from 2016-2022) and more people trying to become a part of it, hence, it won’t be an over exaggeration to say that uncollateralized lending is no longer far out-of-term.
 
This project will benefit the user which has very less or no asset to give as a collateral and still wants to opt for a loan in the same manner.
The method ensures that the borrower is at the side of lower risk but on the other hand, the institution needs some metrics to risk analyze the profile of the borrower, that is exactly where our algorithm for calculating the credit score for the user comes into picture.[financial benefit to the borrower, while also taking care the lender can lower the risk by looking at the metrics of risk profile to take a calculated risk to earn high yields
The process becomes efficient and faster as the lender can analyze the credit risk profile of the applicant and approve the loan faster.
Through uncollateralized means, the loan can be applicable to wider use-cases other than automobile and real-estate.

A bridge consists of two smart contracts: one on each chain that allows for cross-chain value transfers. On the sidechain, ETH deposited in the main net will provide a balance denominated in ERC-20 tokens.

Understanding how they are extremely crucial, extensively used and densely populated with various kinds of chains and tokens, It is imminent to track their data to get key insights on their data and important metrics can be covered using Analytics.

Forgery of documents is a growing problem and demands the utmost attention. The fraudulent reproduction of certificates has increased significantly in recent years, becoming a menace for all the stakeholders. It is not only employers or universities who are duped by fake certificates but also students who are cheated by them.

With our solution, organisations can issue certificates on blockchain without getting into techicalities. Our white label solution can be integrated right into their existing CRM , websites or apps.

The current stablecoins in the crypto ecosystem are Capital-Inefficient stablecoins. The Credit Default Swap market currently exists only in traditional finance and is centralised by big financial players that are opaque with their processes. They also face the critical issue of delayed auction mechanism in liquidating collateral amount. Our project aims to solve these problem statements by bringing this to the DeFi ecosystem.

Vision - Batch multi-step LP processes into a single step.
Problems - 
1. Liquidity Provider(LP) tokens are an essential aspect of providing liquidity for DEXs. But the process of creating or liquidating an LP token involves a lot of steps. The user should have two tokens on the wallet — *Token_X* and *Token_Y. In order to become a liquidity provider, he/she creates a pair of possessed tokens and adds to liquidity to an existing pool. After adding liquidity to the pool, the LP token (LP_Token_XY*) will be added to the user’s wallet. To summarise, it requires at least 3 steps. What would happen if you wanted to create five LP pairs and offer liquidity for each of them? 15 steps! What a lengthy procedure.

2. The second problem is there is no way to exchange LP tokens from one DEX to another. 

Solutions -
Hence, we are trying to simplify these problems so that users can create multiple and exit multiple LP positions in one go.

To do so, we have built three features:

1. Transfer LP tokens from one protocol to another. Example: Transfer an LP pair from Uniswap to Sushiswap.
2. Convert multiple LP pairs and other tokens into a single LP token in one click. 
3. Convert multiple LP pairs and tokens into multiple tokens in a single click. 

To conclude, we want to solve the problem of multiple steps in regard to LP swapping.

Future Improvements - As of now LPSwap only supports QuickSwap & SushiSwap v2. We are planning to scale this to Uniswap v2/v3, Quick/Sushi Swap v3. Also, due to time constraints, we have not been able to add LP token migration to the frontend dapp, where users can migrate their liquidity from 1 DEX(from uniswap to quicswap, etc) to another in a single click.
Also once the v3 version goes live we will add a v2 to v3 liquidity migrator in a single click/transaction.

In the current times, Freelancers face a lot of difficulties to present their previous works to clients and it's also difficult for companies to have that trust in new freelancers since they do not have proof of work. Right now freelancers just attach a few links and show that they worked on these projects but there is no proof that they were the actual ones who did that.

We are trying to solve that by helping freelancers get that Proof of Work for whatever project they worked on. The platform is simple, a freelancer comes to your platform and registers himself and when he raises an invoice and the work gets accepted he will be getting a Unique NFT that will be the proof of work for the project he worked on. 

Apart from this, we are also working on a Payroll system for Companies to manage their employees easily, right now all the payments in companies are done manually on a payday, with our solution the whole thing will be automated, The employer or the company registers onto our platform and gets an ENS Subdomain for themself, once they have done it, all they need to do is add various employees onto the platform with their wallet address and set their payroll price and date. Now the contract will automatically run and send payments to the given employees on their payday from the contract wallet that has the funds.

So the next time all you need to do is make sure that your wallet balance has enough balance and the fund will be credited directly to your employee's wallet.

As mentioned earlier you can also set methods to send funds to freelancers after accepting their work. 

This tool will help you in 2 things, first is managing the payrolls of your workforce and the next one is managing the freelancers that you are working with and release their payments all hassle free without any pain.

blJust imagine you are in 2020 again, your loved one needs the vaccine in emergency but you can't get a real one either due to counterfeiting or shortage although there was a correct amount of production. Feels Horror right! But what if we already had a transparent , anti-counterfeiting and fair supply chain then you would have got your right.

From the last decade, pharmaceutical companies are facing difficulties in tracking their
products during the supply chain process, allowing the counterfeiters to add their fake medicines
into the market. Counterfeit drugs are analyzed as a very big challenge for the pharmaceutical
industry worldwide. As indicated by the statistics, yearly business loss of around $200 billion is
reported by US pharmaceutical companies due to these counterfeit drugs. These drugs may not
help the patients to recover the disease but have many other dangerous side effects. According
to the World Health Organization (WHO) survey report, in under-developed countries every 10th
drug use by the consumers is counterfeit and has low quality. Hence, a system that can trace and
track drug delivery at every phase is needed to solve the counterfeiting problem

Problem:

Data collection, which is vital to government welfare or planning programs, is difficult to obtain without a tradeoff or compromise with citizen privacy. Moreover, such a large data set can very easily be misused or attacked.

Solution:
By using zero-knowledge proofs, such data can be obtained from citizens with an API call (I used NuID- a decentralized trustless API) for this purpose and a dashboard (shown in the photographs) to collect the data.

Value Add:

Citizens’ privacy is not risked, and the ownership of their data is maintained. From a data sharing and regulation(such as GDPR) standpoint, this is highly efficient.

Crypto Legacy allows users to create a will of their crypto assets that will be automatically executed at a later point in time, to multiple beneficiaries on the network. User can approve their desired assets and the amount they wish to pass on to their beneficiaries. Once approved we create a will for their asset on the smart contract. We use the Gelato network to schedule execution of the will at the time of expiry. Once the will expires given the timestamp by the users, the execute will function on the smart contract will be automatically triggered by the Gelato network.

DeFi users have a very bad experience with the current bridges and swaps. 

Bridging, Swapping, & Earning is complex in Crypto!

- Bad UX.
- High Slippage.
- Time Consuming.

Bounce protocol gives a one-stop solution for users to swap, bridge, and deposit in the yield pool.

With just three clicks, a user can deposit cross-chain coins/tokens.

Bounce also analyses slippage and gas to prioritize whether to bridge or swap first.

It is a Live Streaming Platform build on Livepeer for content creators , Events , Shows , Live classes and many more.  

Push Usecase:
-> User can Join a Streaamers Channel,See All his Notifications,See all Channels of PUSH , Join/Disjoin a Channel.
-> Streamer can see his Subscriber's ENS and NFT Profile,

Superfluid's Usecase:
-> We believe in Pay as You Watch model so for every second you watch stream ,money is being deducted from your account and deposited into the Streamers Account when you decide to leave the stream.
-> We didn't went with a SUBSCRIPTION model because people generally regret buying a subs or forgets about it .

Covalent's Usecase: 
-> Won't it be awesome if you could know which NFTs does your favourite content creator has in his Wallets .
 -> We also provide analysis about Nft projects and from which chain most of the money streams are coming from and which collections are the streamer trading in past few days/months using Covalent(Beta).
-> We are also Leveraging Covalent to Check if the Streamer has "Stream Tokens",if he has then only he can Stream otherwise he has to wait till he gets Waitlisted.

LivePeer's Usecase :
-> The streamer can stream using Livepeer using the StreamID and the Stream URL which we are generating in our platform and then give that URL and ID to OBS and then the stream will be started.
Why LivePeer ?
-> Startups are consequently compelled to charge their users by selling their data, torment them with adverts, or cease operations altogether.

ENS Usecase :
-> We are Showing all the Wallet Address who are Subscribers of the Streamer and we are not  showing their Wallet Address insted we are showing their ENS names and it's Nft profile Photo.

Web3.storage:
-> We are using Web3.storage to store Thumbnails of Streams,the reason to do this is because you can see your thumbnails even after 50 years of upload and get some memories of old Streams.
-> The Hosted CIDs are stored on Polygon Chain using Solidity Mapping.

## The Idea

The goal of ETHIndia is make the Web3 ecosystem more simple and easier to  use. To make web3 a practically viable option for everyone to shift on, all the facilities currently available in web3 should be able compete with web2 ones. One of the most used things by people on a daily basis is probably thier calendar application. By creating a web3 native calendar they can manage thier tasks more easily with other web3 native people.

## Solution

Using Cal3 you can maintain blockchain native calendar. You can create events, invite people by using thier wallet address, collect RSVP and send notifications. 

## Tech Stack

- **The Graph:** To index the onchain data 
- **Push Protocol:** To send notifications from the graph to the users.
- **Valist:** To deploy the application online.
- **ENS:** To resolve wallet address' ENS domains.
- **IPFS/Filecoin**: To store events metadata.

We belive in freedom of speech ( which is freedom of press)  and the privacy should not mixed with secrecy. Journalism is often censored and nor everyone has the technical skills of using the onion service (Tor) provided by Gaurdian, WSJ, etc to hide their identity while publishing true events and also getting incentives from it. We Believe in a censorship resistant world which is neither good or evil, as the boundaries between them are often blurred. So we built a privacy oriented Journalism app where anyone can post news. 
	We Built this project in a modular form. The backend is on IPFS using OrbitDB which indexes the news for us while storing minimal information. For the upload part we have write access only to us so that the DB is not bloated, while we can make our key public and everything is open-source. We used ZkBoB to built anonymous single use address system. Also to prevent sybill we made a staking system of Misleading/Reliable. We also used push protocol to enhance the UX as  anonymity often comes with compromises.

### What really is the problem ? 🤔

- Lack of trading knowledge/experience for relatively new web3 enthusiasts. 😥
- Information asymmetry between experienced players of the game and newcomers 🕵️
- Lack of time to strategize professional web3 investment strategies after research and analysis of the market status 🥲
- A lack of communication channels between the experienced and newcomers 🤌✍️👂

### Problem Space Exploration and Solution Motivations

- What do you think was, hands down, one of the most successful models to bridge the gap between someone experienced in some field and a masses wanting to be in the same. Yes, The Creator Economy! 🥂
- Each “Creator” creates precisely what is demanded and henceforth heavily consumed and appreciated by their respective audience, be it academics, entertainment, sports or news thus successfully bridging the gap. 🤝
- In out given case, the “content” is in the context of effective investment strategies, and “consumers” are relatively web3 inexperienced players who would be willing to pay to get access to the strategies in view of larger future profits 📈

### Solution Statement - AlkyneFi

- AlkyneFi is the first ever Dapp to simply DeFi using the power of Creator economy. 😤
- We consist of two major stakeholders, “Managers” and “Investors”. 🤑
- Investor can compare among different Managers from their public profiles containing their transaction records which can be used to gauge how well someone’s investment strategies have been. 🤔
- Investors can further choose to pay a small subscription fee to the chosen Manager to unlock the access to see and replicate their entire investment details using an automated smart contract. ☕️👌

Real Estate industry is a very big and complex industry for any person. This situation happens due to factors like number of paper work, frauds, money laundering and generation of black money. Registration and real estate deals take days to months to years to settle. This can cause a huge inconvinience to any individual. We abstract those tedious process and provide safe and secure environment for users to connect and offer deals with potential buyers without worrying about any paperwork. We store everything on chain and therefore there is perfect data integrity and transparency.
Real Estate inndustry is also a major black money generator industry. Due to low transparency and intermediatary involvement, a large sum of black money cashflows in the market and therefore affecting the nations economy. We tried to minimize that possibility by implmenting on chain communication using Push and on chain dealing so that transparency is maintained and no funny business can be hidden from the eyes of governing bodies.

Slow and Expensive Alternative Dispute Resolution.
The world is experiencing an accelerated pace of globalization and digitalization. An exponentially growing number of transactions are being conducted online between people across jurisdictional boundaries.
If the blockchain promise comes to a reality, in a not-so-distant future, most goods, labor and capital will be allocated through decentralized global platforms.
Disputes will certainly arise. Users of decentralized eBay will claim that sellers failed to send the goods as specified in the agreement, guests in decentralized Airbnb will claim that the rented house was not “as shown in the pictures” and backers in a crowdfunding platform will claim a refund as teams fail to deliver the promised results.
Smart contracts are smart enough to automatically execute as programmed, but not to render subjective judgments or to include elements from outside the blockchain. Existing dispute resolution technologies are too slow, too expensive and too unreliable for a decentralized global economy operating in real time. A fast, inexpensive, transparent, reliable and decentralized dispute resolution mechanism that renders ultimate judgments about the enforceability of smart contracts is a key institution for the blockchain era.
Kort is a decentralized dispute resolution platform that uses crowdsourcing, blockchain and game theory to develop a justice system that produces true decisions in a secure and inexpensive way.

Features offered by Kort:
•	Creation and Resolution of Disputes.
•	Ready Made Integration in 
•	Real World Arbitration.

Problem: 
We all know how even now there is no mass adoption of web3. People are not able to evolve from web2 to web3. Because almost everything that we do in web3 space results in a Transaction state update and it eventually gonna costs you some Gas Fees. So what can we do??

Solution:
There is a psychological impact on people that money has created. People want to pay as less as possible for any kind of work to get done and web2 space has almost successfully done that. People can download the search engine and access the internet and at the same, they can't download a simple wallet and get access to the web3 space.

The major problem is the gas fees. So we are providing a one-time pay solution that includes a subscription Model built on top of gas fees. You know same as we do the wifi recharge and access the internet. 

It would lead to a free-flow transaction experience where the user doesn't even experience his/her money has been spent. And it would lead to creating a psychological impact on the brain of users. The same Uber did with their users, they integrated the credit card system on their application such that people don't even have to touch their wallet and give someone money. 

Advantages we are providing: 
1. We are saying users have to pay less than the average gas spent for the subscription model they opted for. Let's say for one monthly subscription user has to pay 70% of the average gas fees spent by users for one month. And if the user spends less than the given say 40% then the platform will be viable to refund the rest of his money. So it's a huge advantage for users to pay less and access more.

2. Dapp developers have been provided leverage to integrate our model onto their Dapplications. So it ables Dapp developers to let the user on their platform spend money in form of their native tokens. Which will definitely help in their tokenomics.

Our Revenue Model is such that even after providing such high leverage we are the side on advantage.

Today a creator posts Twitter threads when a significant event (like a hack, etc) happens. They paste screenshots from blockchain explorers (like Etherscan, etc) to validate their findings. On top of that there are thousand people publishing analysis for the same event. 

For a creator, BlockBuster significantly reduces the time and effort needed from their end to create an engrossing story along with adding easy visual add-ons on top of everything.

For a reader, BlockBuster is one platform where they can find all social commentary related to a block or a transaction or a wallet (or any combination of these). Readers further get a chance to comment on these stories along with the ability to upvote or downvote a story. We will additionally allow readers to easily donate/gift to the creator of a story.
