This final project from BG Batch 4 initiates the SpeedRun Particle Network platform with 'Challenge 1: Particle Auth,' an interactive tutorial teaching developers to integrate social logins and manage wallet creation in Web3 applications. Participants will learn to integrate Particle Auth with Scaffold ETH, covering authentication flows, wallet setup, and management. It's the beginning of a series exploring further Particle Network services, aiming to enhance developers' skills in decentralized identity management and Web3 interaction. The ultimate goal is to deepen practical Web3 knowledge, inspired by the success of SpeedRun Ethereum, paving the way for continued development within the BuidlGuidl community.

A crypto alternative for BuyMeCoffee. The idea is to have a web page with creator's QR codes in one place. Somewhat like punkwallet.io. Users connect their wallet to our app and click "Tip" the creator. Why would anyone use it when anyone send ETH directly to addresses written in plain text? For the same reason that BuyMeCoffee or Ko-Fi exists - user experience. A lot of plain text doesn't look good, but a creator's web page is much better. Creators can customize their profiles to make it more visually appealing. Users can either directly send crypto to someones QR or tap a button. If they do tap the "Tip" button then the contract takes a small fee of the transaction. I have a smart contract for that, can be improved of course: https://github.com/Paul-Sizon/BitTip/blob/bittip/packages/hardhat/contracts/BitTipContract.sol There is a starting discussion in Batch4 telegram group. There are few questions that should be considered: 1) Do creators register their wallets on chain or do they just register off chain and we pass their wallet as a parameter to the smart contract? 2) Ideally it should support other cryptocurrencies, but that falls out of MVP scope, in my opinion Thank you for considering my proposal. Let me know what you think) Cheers, Paul

Hey 👋 The idea is to create a collaborative storytelling experience. It could be used for events, children or community building. Each user submits inspiration (string, keywords, etc) via a smart contract and the front end will listen to the event submitted where the users addition and the combined “inspirations” and will use an LLM to write a story and generate one or more images suitable. The idea for now is to save the generated story and media offchain. But looking at the event history we can see how the story evolves over time and give the user a way to look at previous versions of the story. I think this shared story building using the LLM as the orchestrator could be fun, and using a smart contract as the way to gather inspiration creates both something of a version history and a way to interact with credentials. Could use a whitelist perhaps? Would love input and ideas ❤️ /perstarkse batch#4 builder

A lot of people claim to have a skills that they add to their resumes / profiles etc. Goal is to have a platform that allows verifiers ( peers) that verify each others skills that they post. Higher verifications get shown in the profile of the user. For example -- say I post that i can work on solidity. I will put proof of work that others can verify. I will also put the rating of the skill that i rank myself -- say 8/10. Others will verify and give their ratings. The goal is to also have the user mint a NFT of all the skills that they have and also showcasing how many people support/verify that.Lastly with all the users skill the user can mint an NFT that can be kept updating as the user adds skills and gets more verifications

Image Generation App In the app, users will have points that will be tracked using blockchain technology. These points can be purchased with ETH. Users can then use these points to generate images. I am planning to connect to the DALL-E API, which will assist in generating the images. [EXTRA] there will be an option for users to view images generated by other users, provided they choose to share them.

A Platform to combat procrastination by leveraging pressure and incentives to motivate users to take action on their goals. By setting deadlines, providing rewards for success, and implementing consequences for failure, users are encouraged to overcome procrastination and achieve their objectives. Additionally, the platform fosters self-improvement and creativity by providing a space for idea-sharing and collaboration within the community. Details: Task Submission and Approval: Users who want to overcome procrastination submit their tasks on the platform. They set a reasonable deadline for completion, which is subject to approval by the platform members. The community members review the task and the proposed deadline to ensure they are realistic and feasible. Collateral Requirement: To commit to completing the task within the specified deadline, users must deposit 0.5 ETH as collateral. This collateral serves as a commitment to follow through on the task. Task Completion: If the task is successfully completed within the set deadline, the user receives their collateral back. Additionally, they earn extra ETH as a reward for their timely completion. The amount of extra ETH earned depends on how quickly the task was completed, incentivizing prompt action. Renewal and Extension: If a user realizes they need more time to complete the task, they can renew it by paying a small fee. This fee allows them to extend the deadline, providing flexibility while still maintaining accountability. If they fail to renew or complete the task within the extended deadline, they forfeit the collateral. Community-driven Support: The platform operates with the support and oversight of the community members. Community members play a role in approving tasks, ensuring fairness and feasibility. They also provide encouragement and support to users throughout their task completion journey. An additional section for Idea Submission and Reward: Users can submit and describe their ideas for personal or open-source projects. The best idea, determined by community likes and platform evaluation, is rewarded in ETH monthly. This incentivizes creativity and collaboration, providing users with valuable inspiration for their projects while also rewarding innovation within the community. By implementing this system, your platform provides a structured environment where individuals can overcome procrastination by setting goals, committing to deadlines, and receiving both incentives for success and consequences for failure. Additionally, users have the opportunity to share and discover ideas for personal or open-source projects. The community-driven aspect not only adds a supportive and motivational element but also fosters creativity and collaboration, enhancing the effectiveness of the platform in helping users achieve their goals and find inspiration for their next endeavors.

An interface for the EVM in the browser, to simulate and visualize your onchain activity, with special emphasis on the costs associated with it. Think ~ Etherscan + Remix + Foundry. Basically, it's a way to interact with a forked EVM chain, in a local-first environment, with a comprehensive set of actions/hacks/utilities exposed by Tevm—which is doing all the heavy lifting. The state of each chain is the initial fork + all the local transactions, which are displayed in the history with all the details (data, errors, logs, inputs...). And also, and that's one of the main points of savvy, details on the gas usage of each transaction (fee, L1 submission fee if relevant...). You can think of it as a way of simulating a set of transactions, and visualizing the results, without having to actually send them to the network. With no setup (wallet, signatures, etc.), in the browser, from any account (impersonation), with any amount of native tokens. And much more to come; see https://docs.svvy.sh/progress

I'm an avid user of Svelte, and I believe it can be a better framework for developing for the future (Web3) if only it had a better ecosystem. I already made a basic port of Wagmi (which I'll improve in the near future) that you can find here: https://github.com/ByteAtATime/wagmi-svelte I'm hoping I can get a grant to port SE-2 to Svelte. The current main problem is that there is no RainbowKit for Svelte, but I'm hoping I can replace that with Web3Modal until I can develop a port. The reason I'm asking for a grant is because I'm developing all this open-source and in my free time, and I'm hoping I can continue to do this without having to bend to whatever a company wants me to do. (Sorry, I'm not completely fluent in English, but I hope you understand what I'm trying to say.)

I will create an introductory video explaining how to use scaffold-eth. The content will be created in Spanish and will consist of a video between 35 and 60 minutes. With the aim of encouraging more Spanish-speaking and Latin American developers to know and use scaffold-eth. Language is a barrier for those who do not understand English and want to access quality content. The objective of the video is to make available quality content in Spanish about scaffold-eth that perpetuates over time, and to invite the Spanish-speaking community to become BuidlGuidl members I have experience giving workshops online and in person, I have been in Argentina, Uruguay, Peru, Mexico, Spain and the USA doing workshops representing Chainlink as a developer expert. I also have a Youtube channel, you can check it here: youtube.com/@observdev
