Products that do what Degen Raffle – A raffle built on Ethereum does
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.…

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!

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…

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 founded the first blockchain certificate of deposit. I'm surprised that it became so popular so fast, I hope it doesn't cryptokitties the network. The marketing looks like a scam.

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:…

Hey HN, I just released Tradofire, a crypto trading app I built using a lot of cursor chatgpt and claude for over a year. The main idea of the app is very simple - to swipe on pre-prepared trading setups (like tinder) and if you right swipe it opens a position. The execution of this simple idea was much more complex and tbh I could not have done it without AI. Here's a quick rundown of the main features: Swipe-to-Trade UI: Quickly initiate long or short positions with intuitive swipe gestures. Real-Time Trade Signals: Get curated crypto signals from the market delivered proactively, helping…

Abstract. Token-funded bounties to incentivize competition-style participation in blockchain development projects would result in wider and better allocation of investment, and allow investors to diversify exposure across a field of potentially successful projects. Overall this would increase the rate of progress within development of the blockchain space. We propose a centralised platform for the administration of token-funded bounty driven development projects whereby experts allocate pools of invested capital according to the technical merits of development projects, and investors are…

I built this site to make it really easy to put cryptocurrency in the hands of people who know nothing about it. It's an MVP, and I have a laundry list of enhancements/feature requests/things I want to do. Still, any non-obvious feedback is welcome. https://cointipping.com
