###This is a No code utility project which is need of the hour in crypto space right now. All the dapps, wallets and blockchains seem too complicated and full of complex code from an external web2 point of view. Someone has to simplify things for the newcomers and make their life easy entering the web3 space. This project would make it easier for individuals and businesses to create their own token and set up its ecosystem, user base and utility at one place.

### Primary Features
1. Designed for the general web2 audience to create their own ERC20 token
2. Can create taxable tokens, where taxes can be set to burn or go to treasury
3. Provides all the associated tooling at one place, like setting up liquidity pools, creating airdrops etc.
4. Creation of customized tailor-fit airdrops, by accessing specific user base of existing Dapps 
5. Every user who opts in to that channel will be notified whenever they receive any airdrop of any token 

LaunchYourToken allows token creators to distribute their token among niche audiences via customized airdrops. We have used the existing subgraphs for major DeFi protocols on TheGraph's hosted service such as Uniswap, Bancor, Compound, Balancer and Synthetix to scan their active user base. For example, while creating an airdrop, creator can chose to only airdrop tokens to addresses who have borrowed more than a threshold on compound, or addresses who have performed at least 5 swaps on Balancer and more such combinations. This makes it easy for creator to target a specific audience.

The long term goal of this project is to allow creators to create more utility for their tokens. We will be focussing more on businesses/stores/brand chains who wish to create their own tokens and use it to provide utility on their own apps. 
### Planned Features
1. Payment gateway for businesses to accept payments using their own token, where customers would receive some discount.
2. DAO tooling for individuals to expand and decenetralize their tokens

It takes a lot of work to execute multiple transactions to various individuals and go through the tedious procedure of gathering every wallet address in order to send token for any purposes. We came up with a special solution for this. Cryptons will convert your token into a single multi-claimable coupon / multiple coupons of the specified value, together with an easily shareable link and QR code. With getting rid of the necessity for the sender to batch many transactions, we make it simple for any user to submit a gasless claim with just one click.
The coupon codes are entirely confidential since they are created on demand using an alphanumeric string provided by the user and hashed with SHA256. There is no centralize storage for coupon codes, only the hashed coupon code, and a predetermined expiration date for coupons, is stored over blockchain after which the issuer may recover the tokens if they remain unclaimed.
Additionally, we do several checks utilising the frontend, api, and on context view methods to ensure that multiple claims are not being over-distributed to a single user.
We are therefore relieving the sender's burden and making it convenient for the recipients as well, since they may claim it to their preferred wallet without having to pay for multiple gas.

There are situations when the gas fee for on-chain computation is really high because of the functions being resource demanding and the general bottlenecks on blockchain. The app can allow the user to get the on-chain computation off-chain using The Graph and then push the result back on-chain eliminating majority of the gas needed to run it.

The NFT art community is constrained by a very limited permutations of NFT combinations that are made with pre-existing layers only arranged and rearranged again and time again one has no element or art and suprise. Thus we created a website that takes a given tweet as input and generates a unique and random image using AI to take NFT art on the next level 🚀
Because why sell your tweets when you sell your tweet art! 
We used OpenAI's text completion and Dall-E to generate image from text, first we find keywords from the tweet using text completion API then we use the output as prompt for Dall-E to generate an image which is later minted as NFT

### Block Alerts solve the following problems:
 - You can get notified when your smart contract function gets executed by anyone.
 - You don't have to check etherscan repeatedly to check if execution is successful or failed.
 - There are 3.2 Million Twitter followers in WhaleAlerts channel so there is a need of alerting for everyone.
 - You can use Block Alerts for debugging purpose of your smart contracts.

NFT projects are always faced with a choice between **value accrual on mainnet** or **cost efficiency of other L2s/Chains**.
This project's intention is to bring NFT projects out of this dilemma and establish a solution without compromising either of these 2 choices. 
Each Protocol is unique and has its own needs. 
**Hence NFTCrossRoad presents 3 unique solutions.**

A blockchain based reputation system allows immense amount of analytics. For this, we need consistent and regular rating behaviour by users.

Pain points of the existing system included
1. Platform manipulation - Merchants can buy reputation score or remove comments/ratings hurting business without improving.
2. Stale rating - Once a large reputation score is achieved, bad performance doesn’t reduce it due to an averaging.

By creating a mechanism of incentivising users to provide ratings every time and for every experience, it attempts to bring promote consistent ratings and more real reputations based on activity. 
* It solves problems like Platform manipulation and stale reputation scores.
* It can be applied to various categories -  Merchant platforms, B2B, B2C
* It introduces a decaying reputation and tokens and rewards activity and participation.
* DAO controlled reputation calculation mechanisms(replaceable calculations, updatable thresholds)

REP token
- The users are rewarded a REP token for every review. 
- REP token can be burnt to boost reputation score(within limits). This helps upcoming  businesses improve Reputation score.
- Customers can redeem their tokens for discounts by transferring REP to businesses.
- REP can’t be traded across accounts and hence can’t just be bought.
- REP tokens and Reputation score both have a decay rule built into them. Being active is the only way to keep it up.

[nb: I proposed this idea in a previous hackathon(no code implementation). However, this time I have added more detail and some code implementation.]

Ease NFT allows users to seamlessly buy the NFT without the hassle of waiting for a transaction to complete. NFTs buying experience has always been delayed by complex interfaces with multiple chains, juggling multiple wallets and no real time update of the NFT purchase from the blockchain network which creates uncertainty in the buyer to make the purchase.

Ease NFT, combines the power of multiple protocols to provide simpler and quicker solutions to all the NFTs problems. With the unified API powered by Covalent, we are able to seamlessly query the network and contract to get the real updates from multiple contracts. Similarly, Push Web Notification allows the user to stay up to date regarding their NFTs transactions with real time update. Finally, the complex architecture deployment of the NFT marketplace is solved by the one click deployment solution provided by the StackOS.

In a Web2 world, users and original creators do not get fairly compensated for their user generated content. On Tiktok, for example, you can have a reel go viral with a billion views, but neither the creator nor any music (or other creative output) used in the creation of the reel gets fairly compensated by the platform itself. 
In a Web3 world, licensing, attribution, and fair use can be updated and enforced on-chain permissionlessly.
One of the use cases we’ve imagined for the NFTs artists release on our platform (and others, using our protocol) is the ability of fans to create user generated content (think fan remixes, mashups of multiple songs, etc.) permissionlessly. 


A.live Composable, Remixable NFT Protocol

It is a smaller version of ENS on the Polygon blockchain: anyone can buy a domain NFT and direct it to something. This is fantastic because once your contract is on the blockchain, any data it contains will be global! Anyone can read the names and figure out what it's pointing to. And, because blockchains are unstoppable, no one can erase your data or destroy your epic domain.
We think of name services as global APIs. They are accessible to everyone, and you can store data that can be queried. ENS allows you to save a large number of items.

Lens Protocol currently only supports single user-based profiles; we created LensParty, where people can create community profiles.

Using LensParty, a user can create a community like Reddit.

While creating, the user can specify the conditions that need to be satisfied to interact with the community.

Lens Protocol only supports notifications for interaction with the logged-in profile.

LensParty also has Push protocol support because users can now receive notifications on their phones and browser extension.

By using LensParty, we can have organisation profiles in Lens Protocol!

Short-form video content is on a rise all over the world. Social Media giants are integrating short-form video content mechanisms to create more engagement among users and creators. But these companies generate proprietary software and own all the data on their platforms
Introducing LensTok, a decentralized short-form video content platform built using composable and decentralized social graph powered by Lens Protocol. The users have full control over their online social presence and creators are no anymore at the mercy of closed-source algorithms to generate engagement

We have developed a lot of features to get you started on our platform.
- Social Login: We use Biconomy's social login SDK to ease out the transition for new users and bypass the overhead of setting up crypto wallets
- Upload videos: In our platform, content creators get the ability to publish their content all over the world in a decentralized manner empowered using Livepeer Video API (On Demand) and IPFS / Filecoin's Web3.Storage.
- Explore Timeline and Following Timeline: Users get to choose to browse through content on the platform in both explore and their following creator's timeline formats
- Notifications: No user can miss out on any updates on new video uploads from their favourite content creator. The notifications are powered by Push Protocol
- Collect Posts as NFT: We incentivize human interactions on our platform. Hence we use the World Coin Verification system to initially verify an individual as human and then only enable them to collect Posts as NFTs. Creators of these posts get notified instantly using Push notifications
- Profile Pages: We enable users to go through the videos uploaded by other users/creators and videos collected by them through their profile pages
- Top fans private call: We provide the creators to see their top fans on our platform and provide them an option to have 1-1 video calls with them in a decentralized manner powered by Huddle01 video conferencing

Background - the feeding hands that keep us all alive are ignored and
abused around the world in various ways. A lot of the famers are stuck
in debt traps for a few reasons: non-availability of reasonable,
timely credit; lack of differentiation in pricing of their products;
unavailability of proper insurance; poor compliance to standards of
agriculture practices; degradation of soils year in and year out and
others.

Carbon Mint addresses some of these problems by on-farm traceability
of practices, inputs & quality using geo-stamped, timestamped and
user-stamped data on the blockchain.  The data acts as evidence for
compliance and makes certification processes much more robust and can
significantly reduce fraud in organic & natural food production.

In this hackathon, we focused on a model of farming known as
"demand-driven" farming where a buyer commits to buying product at a
certain price range. We implemented a set of smart contracts to
connect wholesalers, farmer groups and farmers in a way that farmers
get early prepayments for seeds, inputs, tools etc.  Buyers get
transparency, accountability and overall better quality products.

We believe that implementation of smart contracts to accompany
physical contracts have several benefits:

- evolution of new approaches to funding farmer investments, such as
  evidence-based pre-payments (and perhaps in the middle of the crop
  cycle as well) to reduce the captial outlay for the farmer, and
  reduce their dependence on high-interest loans
- coupled with traceability solutions, the transparency and
  availability of indisputable data gives higher degree of confidence
  about the quality of the harvest, demanding premium to the ultimate
  product.
- Representing the contracts as NFTs allows trading of the contracts 
- Insurance companies are more comfortable to underwrite on the
  strength of foolproof contracts + data
- data tracking also makes it possible to measure the value of the
  agri systems via tokenization

Account2 is a contract designed to accomplish three key features not yet enshrined in the Ethereum protocol, i.e., Account Abstraction, Economic Abstraction and Account Linking.

Account Abstraction - the ability to have an account that will allow a relayer to act on behalf of the account owner as msg.sender. This will solve three major UX challenges experienced in the first allowing all transactions to be bundled in a single transaction (i.e.: the necessity for an approve transaction before a swap transaction). Next it will allow a relayer to sponsor the gas for a transaction which is a major UX hurdle for Ethereum adoption. Lastly, a controlling key that has been compromised can be replaced in a single transaction transfering all the asset held in the Account2 account.

Economic Abstraction - the ability to pay an Ethereum transaction gas fee in any ERC20 token. Economic abstraction allows the user to pay for transaction in any ERC20 they hold in their Account2.

Account Linking - the ability to associate accounts hierarchically with a single private key. Since the owner of an account can be a contract we set the owner to a root Account2 and all requests will begin in the root Account2 and will be forwarded to subordinate Account2 accounts. Using singly linked design we can establish any level of heirarchy with minimum overhead for each hop.

Account2

People can use it for uploading anything that will make future-them experience a gush of nostalgia. This app is meant to used for entertainment purposes. For example, I could upload my journal entry and set the capsule time to be at 5pm on Jaunary 22, 2030. Then I'll get an NFT containig the entry airdropped on said date and time. I will also receive a notification regarding the air-drop. The frontend is deplyed immutably to Valist.

IPfy is platform to list and license copyrighted and patented work. 

Problems:
1. IP registering and licensing is a resource intensive task often requiring expensive legal assistance.
2. Addtionally, creators who provide open source creations/inventions are not appropriately attributed and rewarded. 
3. It is difficult to asses the vallidity of new inventons and creations.


People can use IPfy to record their IP on blockchain, license it to users for a fee (fee optional), where all IP license transactions are also recorded on-chain. Potential licensors and licensees have a chat function to communicate for clarifactions. The above stated problems are thus resolved:
1. External invervention(legal and ors) can be avoided, by automating the licensing process. The creator must only provide details of their IP and its curresponding registration ID. Addtionally, for creators/inventors who want to register their property, but don't have the means to do so with a govt./govt. recognised authority, they may record it on the platform and have a timestamped proof of their creation, serving as reliable evidence. They may also apply for IPfy grants for official registration. 
2. Creators who publish license fee free work, to promote innovation, shall be attributed if other users use their work. Any person(s) creating new work, relying on another open source work, will display the open source invention/creation card on their profile. Users are also given the CHOICE to make small payments to suppport the open source creators/inventors. 
3. Potential popularity and utility of the invention/creation may be identified by evaluating the transaction history of the license, recorded on the blockchain. 

IPfy

🚀 IPFS & Filecoin — 5️⃣ FVM Track: Top 5

Problem it solves: 

- Lens right now doesn't have a platform to support creators except for collect modules through publications. 

- Avoid entering personal information: We need to give a lot of personal information on existing crowdfunding platforms that is not needed for the platform or either useful for consumers like IP address, Browser fingerprints, Location data.

- Privacy: There is no privacy on the existing platforms, all the data we gave are sold for advertisements, and all our posts and chats are monitored by 1000s of mods and admins.

- Downtime: The app we use right now is prone to downtime because that is hosted by a single company with a limited amount of servers.


How we solved it: 

- We built Cryptster, decentralized crowdfunding platform where creators can accept cryptos from their followers without need of sharing address in simple UI

- Personal Information: You don't provide any personal information except your username (it's your choice) and wallet address, and we don't collect any sensitive information and it's difficult to store those in Smart contracts.

- Privacy: Cryptster or Lens team don't have access to moderate your tiers, every tier and info you enter is public

- Downtime: Cryptster is hosted in a decentralised chain and decentralised file storage system IPFS, this means there will be 0 downtime and no one can DDoS the platform.

[Issues]
The main dilemmas of Web2, or traditional, credential issuance are privacy infringement, data security issues, inefficiency, lack of portability, and loss.

1. Data security
    1. For example, people are afraid of mapped their SNS accounts and Wallet address without any permissions. It’s important to keep data security.
2. Privacy concern
    1. Privacy concern is also important. Even though we have several off-chain credential projects, most projects do not protect users' privacy. Users need to share social media authentications to get credential data. We think that is a centralized way to get credentials.

So here is why decentralized off-chain credential data is needed.

Confimo
Identity holder: User
Verifier: Web3 Project
Issuer: Confimo

Existed project
Identity holder: User
Verifier and issuer: Credential Project

Verifier creates off-chain credentials and set up issuance process, then Confimo carries out the issuance process and issue off-chain credentials.

Existed projects need to verify and issue off-chain credential at the same time because they need to verify SNS accounts.

In our system, we assume SNS verified since Web3 projects have done giveaways 

Since Confimo uses Web3 Project as a verifier, we don’t need to get SNS accounts to issue credentials. This produces the pure decentralized credential issuance system.
 

[Technology we used]

Polygon ID: We use Polygon ID for credential. Users create DID and ask claim after receiving giveaways from Web3 projects. We issue credential based on their community activities.

Worldcoin: Web3 projects can get KYC to avoid scammers and bots for rewards.

📇 Polygon — Best use of Polygon ID

In web3 world, if one wants to interact with the ecosystem, he needs to create a wallet and pay a gas fee every time he uses the service. In both cases, the user interfaces are not friendly to non-crypto users.

When it comes to arbitrage, a user must buy and sell crypto assets on multiple exchanges, swaps, etc. During these scenarios, the user will incur huge gas and time fees. Particularly in the crypto space, the market can deviate in a matter of seconds.

Bicotrage

🥈 Biconomy — Best Transaction Batch using the SDK

There are two challenges: the user's problem and the developer's issue.

Gas prices are a serious problem for mass adoption. Now, lots of people can easily get NFT even if they don't have a crypto. However, if they cannot pay for gas, they cannot take advantage of the utility of NFT.

Developers also have problems with cross-chain development. Each cross-chain messaging protocol has a different interface, so each must be implemented by reading the docs, which is time-consuming.

Currently, there are many options for RPC providers in web3, some are better in terms of speed, some are better in terms of availability, and developers have to choose only one between these many options which satisfies their needs and we all know no RPC provider exists that satisfies all of the needs of a web3 developer, we can solve this by giving developers option to load balance their RPC queries between multiple providers. As RPC requests are load balanced between multiple providers, users will get the best possible RPC provider at the time of making the request.

*We are using 2 algorithms to facilitate this - Round Robin & Dynamic Balancing*. Round Robin lets developers switch RPC providers after some successful requests from an RPC provider. Dynamic Balancing lets developers add some weights and options with which we will dynamically balance RPCs and use them.

We have built a JS/TS SDK which works well with ethers.js and web3.js.

This makes current interaction with web3 much faster, and easier and reduces the risk of low reliability as dApp will use multiple RPC providers.

This SDK not just load balances requests between multiple RPC providers but it also caches those request for some amount of time and then invalidates it, you can also choose which methods to exclude from caching, this is very crucial in increasing speed as methods like eth_chainId and similar can be cached for a longer time. It also retries once any requests fail with different provider thus increasing reliability of the whole system.

web3 projects want to offer rewards to well-intentioned users to attract volume to their protocols. incentives like: 
- airdrops, 
- allowlists, 
- gasless tx, 
- yield boosts, etc 

but, one major pain point is that  bad actors can easily exploit these offers with sybil attacks and bots. 

**horsey solves this problem** by integrating the worldcoin SDK for proof-of-humanity logins combined with metamask snap. once a user is logged in and verified, they can access exclusive offers from protocols who can be sure that the rewards are going into the right hands.

Currently, to transact in cryptocurrency, the sender needs to know the EOA address of another user. Remembering the address is really hard Hence there has always been a need for easier ways to represent users and transact with them. Solutions like Paypal and Paytm solve that by identifying users with their Phone numbers/VPA/Email IDs.

Our solution provides space for the mass adoption of crypto payments by making it super intuitive and easy to use.
