Hi guys, I am building Ethercup and I wanted to show you how it works: https://ethercup.github.io/ . On the website is a demo bet live right now on the Kovan test network. This bet opens today and will close in a few days. A How-to is provided on the website, but you can check out the code directly on GitHub: https://github.com/ethercup/ethercup.github.io There's no bug-bounty program, but I'm willing to share profits (if it'll yield any) in case you can break it and point me to it. Looking forward to hearing your feedback :) Also, feel free to ask…

I wanted to see how difficult it would be to build a web app using a sub-$300 android smartphone. Decided to build a fun predictions website where you could bet virtual (not real) money on predictions made by others, and also make predictions of your own. Building it turned out to be considerably easier and more fun than I anticipated. Primary tools used were: # QuickEdit as the mobile code editor (Note: the free version of the QuickEdit app is riddled with ads, it shows an advert each time you close a tab, but it unfortunately had the best UI of the 3 or so Android code editors I tested.…

With my friends we wanted to have a nice friendly competition (no money involved) about the football worldcup by predicting the results. I though this might interest other groups of friends so I coded a website just for that in 3 days. Nothing ground breaking but I like the suscription system "Doodle" style with just links, no personal infos... Tell me what you think !

I created a bot which analyses Euro 2024 betting odds and performs some basic analysis based on the recent form of each team and provides advice on which odds are under/over-priced by email to all subscribers. The intelligence of the bot is admittedly rather basic but this simple app shows how easy it is to reliably scrape and parse structured data with AI and perform insightful analysis. The initial version of the bot, shown in the notebook took about 15 minutes to build. Disclosure: this bot is built on our new graph based #nocode platform NodeScript.dev, which we've recently brought…

I know everyone is a bit burned out on blockchain and cryptocurrency related stuff around these parts, but I've been working on as a side project for the last few months and thought you guys might be interested: https://cryptoempire.io/ It's still a bit buggy and incomplete (the mobile ux needs a lot of work, the leaderboard isn't functional yet, etc.), but I've reached a point where I'm not totally ashamed of sharing it :) Any feedback would be most welcome!

Hey HN! I've been working on this idea off and on for a few weeks now and I figured it was time to show it to folks before continuing to build it out any further (hence the terrible UI). The idea is this: A smart contract that allows players to win the tokens in the contract in proportion to the number of tokens they've depositing into the smart contract. For example, if you and another player enter a round with 1 token each, you both have a 50/50 shot of winning the other's token. Here's the catch. Anyone can end the round at any moment, even people who haven't deposited any tokens.…

Hi guys, I've written the first proof-of-mistake crypto token on top of Ethereum. You can see it at http://www.lostethereum.com/ It's basically a proof-of-burn substitute for users who mistakenly sent to the wrong address. It requires a web3 enabled browser, i.e chome with MetaMask, Parity, Mist, etc. This let's the web interface seamlessly interact with the Ethereum network. Let me know what you guys think.

I built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.

VSCode extension with games (Snake, Plinko, slots), HN/LessWrong reader, and Pomodoro timer for AI coding wait times. Fake currency only. Marketplace: https://marketplace.visualstudio.com/items?itemName=TouchGra... Built in a week with Claude Code after seeing Chad IDE get ratio'd for integrating real gambling. Happy to answer questions or get roasted on the code.

Hi HN, I'm the creator of epress. After a lot of work, I'm excited (and a bit nervous) to finally share it with you. For years, I've been feeling like a digital tenant on the platforms I use every day. My content, my social graph, my online identity—they were all stored on someone else's servers, subject to their rules, algorithms, and business models. I could be de-platformed, my data could be sold, or an API I relied on could suddenly be put behind a paywall. I looked into existing decentralized alternatives. While many are great projects, I found they often shifted the trust from a big…

I am building a simple donation platform where creators can accept tips in crypto — kind of like “Buy Me a Coffee,” but Web3-native. No signups required for supporters. Just share your donation page and anyone can send MATIC, ETH, or any ERC-20 token directly to your wallet. It’s gas-efficient and built on Polygon. Each creator gets a customizable page with a short URL and optional message board. Everything is non-custodial — you own your keys and your funds.

http://playbitpoker.com Hey, this is my first startup project and I'm pretty excited. I've got to the point where I feel I've got something solid, and I don't know what to do next. I haven't had masses of people using it and testing it with the test-network bitcoins. I have tested it a fair bit with friends and it seems there's no major problems. What should I do? Is this a minimum viable product? Should I try and promote it while it's still in testing, or should I switch over to using real bitcoins before doing that? I'd love to hear any suggestions you might have. P.S. I had…

Hi guys, It is no secret that I'm pretty tired of the political infighting around Bitcoin. The environment got so toxic that I stopped most of my Bitcoin-centric development to focus on other projects. I'm pretty sure there are many developers who have felt the same way, and the result has been an explosion in alternative coins and technologies as developer resources have gone elsewhere. So, I started a simple experiment. What if we got rid of developers entirely, and just replicated and adapted the deflationary structure of Bitcoin on Ethereum. We could model the entire process as an…

Like in the movies when they show a current newspaper, but easier and safer. I use as seed the last mined ethereum block, and I show it in a fancy way.

Hi all! With the World Cup around the corner, and being a football fan, I went looking for apps that would give me a detailed overview of groups, matches categorized by group or team, a daily timeline of when games happen that day (especially useful for us in Europe, since some games run pretty late), and a way to follow my favorite team or teams. The problem I ran into was that most apps out there are pretty bloated — like, really bloated. The ones that weren't either didn't focus on the World Cup specifically, or were ridden with betting ads and ads in general. So I built a very minimal…

Hey everyone - my friends and I have been working on a mini 3-a-side fantasy draft game for the world up. You can find it here: https://nutmeg.app/ We've been working hard to get this out in time and really encourage feedback on how to make it better. On our horizon is thinking through how to expand this for other competitions (e.g. Champions League) and perhaps a full season long game as well. Thanks!

This weekend I participated in my first hackathon at TechCrunch Disrupt, and built an HTML5 game with a few people that I met at the event. We got honorable mention, putting us in the top 6 teams of 104 competing. I'm looking for some feedback on the game, so here it is: http://venturecrapital.us Source: https://github.com/wylieconlon/Venture-Crapital https://github.com/dmitric/venturecrapital-server

We've set up DeekSeek R1 with a system prompt that attempts to censor the word PRIVATEKEY from its response. If you can get DeepSeek R1 to output that string (not in the reasoning, but in the final response), the system will reveal a private key which contains $1000 USDC. You will have a 50 token limit in the input. We will have a series of contests, sponsored by AI researchers, in order to learn more about prompt engineering and how LLMs interact with real money. Good luck! Edit: The money was claimed! Thanks for playing all. You can still play for fun. Stay tuned for the next one! Stats:…
