Products that do what I built Raya Cash – A solo project creating a virtual bank in Argentina does
I spent the last year building Raya Cash, a virtual bank designed specifically for the Argentine market. As a solo founder, I handled everything—from coding the platform to integrating features that cater to both local currency (ARS) and crypto enthusiasts. The goal? To give users in Argentina a secure and efficient way to manage their money, bridging the gap between traditional banking and decentralized finance. Would love your feedback or any questions!

Hey everyone! I just built a mobile app using Expo (React Native) for a platform that moves $6M/month. It’s a neobank used by 6,500+ nonprofit organizations across the world. One of my biggest challenges, while juggling being a full-time student, was getting permission from Apple/Google to use advanced native features such as Tap to Pay (for in-person donations) and Push Provisioning (for adding your card to your digital wallet). It was months of back-and-forth emails, test case recordings, and also compliance checks. Even after securing Apple/Google’s permission, any minor…

Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know…

I've been using this daily for 4 months and figured others might find it useful. This is my first open source project so would love any feedback. Ray connects to your bank via Plaid, stores everything in an encrypted local SQLite database, and lets you ask questions about your finances in natural language. No cloud, no account, your data is stored on your machine. Before anything reaches the LLM, all PII is stripped — your name, companies, transaction details are redacted and replaced with tokens, then rehydrated locally in the response. The AI never sees who you are.

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.

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 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…

For years, I have struggled to understand my cash flow and save for the future. In addition to that, my wife has many credit cards and accounts that complicate matters. I am building a tool that connects all our accounts, helps us create a budget, and tracks and adjusts expenses on the fly. I am also sprinkling some AI magic on it for financial suggestions. I am looking for feedback on the implementation. More importantly, I am looking for more beta testers to improve the product.

I started DCA’ing into BTC many years ago. I kept missing buys, buying emotionally into pumps, and forgetting during chop. So I wrote a simple script that hit an exchange API once a day with a fixed amount. Friends asked to use it, so I generalized it and added a DB to manage multiple users. Why I didn’t use existing tools: Most options I tried were either locked to one exchange or did fixed-amount DCA with naive execution. I wanted multi-exchange support and a way to scale buys during dips and preserve capital during rips. I also kept running into inconsistent API rate limits and…

Experiments are fun. I recently came across Bitclout, and I love the underlying concept. It’s ballsy, will it work? — time will tell. I think Bitclout as a thesis is moving towards the right direction. Decentralised Social Media networks will be the next thing and allowing users to own their own social equity and monetise that is the future. Last year I started an experimental fund, Khoob (www.khoob.group) The idea was to invest in and build interesting Indian companies (a Betaworks / Expa for India). Thus far we have made 4 investments, and are building 4 companies. At Khoob I’m the…

I'm Canadian, live abroad, and my money is scattered across two countries, multiple currencies, banks, brokerages, real estate, and some private equity. No app could hold all of it, and none could answer a simple question like "what's my actual USD exposure?" Brisa pulls everything together (Plaid + manual accounts + real estate + PE, all multi-currency) and puts an AI on top that has my full financial picture in context. Instead of clicking through charts, I can just ask. Would appreciate any feedback!

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.

I am Isaque Franklin and I build products and solve problems in my free time (between college and work) and also for a living. I am a Bitcoin maximalist and I truly believe that Bitcoin is the sanest money that exists today, and I also belive that hard money is essential for the development of civilization and for the future of mankind. However, one cannot uderstand Bitcoin and all it's applications and benefits without falling down the rabbit hole - an experience every bitcoiner has tasted in the beginning of their journey and constantly tastes when learning new things about bitcoin.…

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…
