I've recently went through a full cycle of learning about cross chain transfers and protocols in general. I went from just knowing how to use a bridge to knowing exactly how a bridge works, by reading the documentation of the protocol, examining the call data, etc... I found that generally when you try to read the docs of a cross chain protocol, they all have their own language, and its very difficult to digest for someone new, specially to implement something on top of it. I want to create a wiki, that goes from the most simple concept of a cross chain protocol, demystifying it, maybe even creating the most simplest form of a cross chain protocol, and expand from there to the many and most famous cross chain protocols there are.

A Scaffold-ETH 2 extension to test EIP-712 signatures. My first idea is a simple form to generate the domain, a form to generate the data, and a button to sign. When the user signs, the signed data is displayed on the screen and console.

In Argentina, to rent a property you have to take out a guarantee insurance that costs up to 3 times the value of the monthly rent. My proposal is to create a smart contract that works as a guarantee, where the tenant stakes the guarantee amount, in case he stops paying the rent. Meanwhile, the funds will be deposited in aave so that they do not lose value. At the end of the contract, if the tenant complied with the conditions, he will be able to recover his stake. This application proposes to solve a real-life problem through the implementation of a smart contract. Technology that I should learn to use: - Interact with usdc - deposit usd in aave

I want to build a framework designed to simplify meta-transaction-based cross-chain token creation specifically for developers, available through a dApp, API, or widget. Currently, users need to acquire cryptocurrency to pay gas fees for creating tokens, which makes onboarding new users complex and discourages users. My solution tries to remove these obstacles by allowing developers to integrate token creation functionality in their product. Utilizing meta-transactions, users only need to sign a message, while a relayer takes care of the blockchain transaction, covering gas fees. This solution streamlines token creation, making blockchain integration more accessible, and efficient for products and help attract new user-base to the platform.

This project will demonstrate the real-world utility of blockchain beyond speculation, potentially accelerating mainstream acceptance and use of cryptocurrencies on a global scale. Through ZakatChain, we aim to set a new standard for transparency, efficiency, and trust in charitable giving, while simultaneously driving significant blockchain adoption across the Muslim world.

This document outlines a decentralized torrent platform leveraging Ethereum for torrent metadata and IPFS/Arweave for descriptions. The frontend searches Ethereum and selected torrent sites, highlighting those found on Ethereum and scraping others for missing torrents. Users can add new torrents to the blockchain, ensuring greater availability and persistence. Future enhancements include automated scraping funded by user donations and a “Hall of Fame” recognizing top contributors. This feature encourages active participation, building a robust, decentralized torrent repository on Ethereum. You can find complete system design here: https://phantom-slip-78f.notion.site/Decentralized-Torrent-Platform-e1533e7b70d145acaf7708bfa747ba89

Hello, I want to create an online food ordering website. The user will come to the restaurant, then user will be able to order the dishes from the website. While completing the order, website will ask for user's table number. After the order is created, it will appear on the manager’s screen. Here, manager will be able to view the details of the order. Once the order is completed, the manager can mark it as delivered and remove it from the screen. This is my plan. If you have any suggestions, I would be happy to hear them. Thank you.

Hello everyone, I want to create a Web3 survey application. If users provide consistent answers, they will receive a certain ETH reward. Some questions will be interrelated to measure whether users are answering consistently. If it is determined that a user has provided inconsistent answers, they will be blacklisted and will no longer be able to participate in the survey. Thank you very much for all the help you’ve provided so far. See ya.

An in-browser playground for dApp development that provides the ability to start dev work (including front-end code) within seconds! HOW? Send someone a link that will automatically: 1. Open StackBlitz 2. Start a Hardhat Network, `yarn chain` 3. Run `yarn deploy` 4. Run `yarn start` 5. DONE, you now have a full IDE in seconds BENEFITS: - Other tools (Remix) only focus on Smart Contract dev, but that's only HALF of the dev flow. - Providing shared/repro links to common issues/examples will GREATLY improve the dev experience when debugging problems. ISSUES: 1. This will require continued investigation into producing examples that fully work with WebAssembly (a limitation in web containers) 2. Non-localhost network comms are tricky

The platform enables the creation of decentralized token systems using blockchain technology for a wide range of applications. Users can easily create custom tokens for purposes such as food tokens, loyalty programs, event tickets, or community currencies. It supports transactions with USDT, ensuring seamless token issuance and management. Blockchain technology guarantees transparent and immutable transaction records, protecting against fraud and manipulation. The platform also should have an intuitive mobile app with NFC and QR scan capabilities, making token utilization straightforward and enhancing operational efficiency across different use cases.

Hey gang, I'm 3vil7win, and this is my first proposal coming from batch 7. I'd like to 'port' SE-2 to electron using at least one of the following wallet technologies: metamask electron sdk, walletconnect, or frame (it is not trivial to add extensions to an electron app, though it may be a possible expansion). This project could be a good starting point for other developers to build desktop and mobile versions of dapps. Electron apps are both an approach to frontend decentralization and a springboard to get dapps listed on mobile and other app platforms. I think these capabilities are definitely good extensions for SE-2. I appreciate any thoughts y'all might have. Thanks!

I aim to build a privacy-centric data marketplace where users can contribute valuable data through surveys. These surveys will be created by users of the platform, who will also attach monetary rewards to incentivize data contribution. Developers will be able to purchase these datasets directly from the survey creators. To ensure data privacy, I plan to use encryption and Fully Homomorphic Encryption (FHE), which will allow developers to use the data without seeing or storing it, thus maintaining privacy and preventing data piracy. This marketplace is designed to facilitate both organized and unorganized data trading, targeting AI/ML developers and everyday users who want to contribute data securely.

Treasure is an app that enables users to exchange Ethereum (ETH) for a specific token, stake this token for a defined period, and earn rewards based on an Annual Percentage Rate (APR). In addition to regular staking rewards, the app introduces a gamified element where users have a chance to win a bonus reward when the total amount of staked tokens reaches a predefined threshold. Users can also exchange the tokens back to ETH, ensuring liquidity and flexibility.

iTheirs is a platform that allows you to create ideas that you think about. Those ideas that comes to your mind about a product or an invention that you want to be able to share with others or that you want to tag to a particular firm or company. This is what iTheirs gives you the ability to create. You create these ideas and can either mark them as public or private, but either way. The ideas you create are stored on the blockchain and they are bound to you. Benefits: 1. Because your idea on iTheirs becomes bound to you. If a company decides to reward an idea. They know who to reward. 2. iTheirs allow sharing of ideas without barriers. 3. iTheirs helps to know like-minded individuals and foster better relationships among such individuals.

I have this idea to build on top of the state channels challenge in SRE. In the challenge there is a "guru" and a "rube" that pays for the guru's wisdom. In this idea the guru would be a chatGPT API and the rube a user asking questions... It would be basically a wrapper of chatGPT but you would use the state channel and ETH for payment It would be cool because you will pay only for each character that you receive.

For my final project as part of batch 5 I would like to build a chat room application The flow of the application is as follows: - when users log in on connecting their wallets, they see a list of existing chat rooms - user can either join an existing chat room or create a new chat room - in the chat room users see a list of all other users in the chat room and can also contribute to the chat

As a gamer, you know that your in-game rank is more than just a number. It's a reflection of your dedication, skill, and progress within your favorite games. With Video-Game Rank NFTs, you can now immortalize your gaming profile rank as a unique, dynamically updating NFT. Players want to show off this rank using this NFT. This NFT will dynamically display the rank of the user in game. The primary games that we can target is Dota2 it has free and open API's to get information. We can allow the user to authenticate using Steam OpenID Auth to validate if they own that account and mint their own rank NFT which can display their in-game competitive rank. We can have the nft update periodically (every day or so) to automatically update the rank.

Feedback Forge is a decentralized platform for providing and managing feedback in community-driven projects. Users can leave feedback with a 0-5 star rating and an optional comment. To ensure quality, only users with a certain reputation or those who stake Feedback Forge Tokens (FF) can give feedback. Users earn FF tokens for their contributions, incentivising active participation. This platform promotes transparency and continuous improvement by leveraging blockchain technology. Support for Feedback Forge will drive innovation in decentralized feedback mechanisms, that could be maybe used within BuidlGuidl ecosystem. For now, it's just an idea, for MVP I would like to buidl. I'm open to any feedback, pun intended, myself. Cheers!

I'm looking to build a platform where people can share ideas that they need funding and others can invest in those ideas. We know that sometimes to get a product out, there is a minimum investment needed. So if the investment goal isn't met, the ones who invested will receive their refund automatically. If the goal is met, the money will go to the project owner (might need to stay in a contract so he can't rugpull) and the invertors receive a ERC (20 or 721). The basic build will be the frontend where people can request funds / funds and the contracts on the backend.

I would like to use chainlink functions with Scaffold-eth to consume a weather API and use the data to transform a user-dynamic NFT (different NFT for day and night and metadata). This is a basic proof of concept and if all goes well I want to use this template for a web3 game idea. The repo could be used as a template for anyone wanting to use scaffold eth and chainlink functions and get started quickly. Thank you.

Currently, projects like TrustWallet and etherscan.io control if a token has a logo, and other information related to the token. A very centralized and expensive process for new tokens with no guarantee that the token data will be updated after spending ~$500-2,500USD for each pull request. I propose making this decentralized, storing logos on IPFS, allowing the contract deployer and owner the ability to update information about their token using a smart contract and a Scaffold-ETH frontend.

Xplorer is a blockchain explorer designed with a focus on DeFi users, especially those in lending protocols. Initially launching as a minimum viable product (MVP), Xplorer aims to validate its innovative approach by tracking and documenting interactions between blockchain addresses and mainstream web2 applications like Uber and Amazon. This initial phase involves assigning points to blockchain addresses based on their off-chain activities, which are crucial for understanding a user's broader financial behavior. The MVP will leverage this data through smart contracts to compute an on-chain trust score for each address. This score aids DeFi platforms in refining lending terms, enhancing risk management, and offering personalized services.

Jekyll plugin to enable any Jekyll website to work with Frames.

Anyone with a wallet can post status messages into the contract which can be read via events. Anyone can DM any other wallet by encrypting a message with their public key. After the initial MVP, later additions can be: - 'Verified' users with additional privileges - Setting NFTs as profile pic - Rewards distributed to incentivize participation

A smart contract that any protocol could implement in the event of an exploit. Hackers can deposit the exploited funds into the smart contract and automatically receive a portion of the funds back as a bounty. Additionally, the hacker could negotiate the percentage they receive. This project aims to encourage hackers to return the funds.
