delegare▲70Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…

Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

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.

Hi HN, I'm Nick Slaney and my team is building moneydevkit (https://moneydevkit.com). moneydevkit is the fastest way for anyone to add payments to their website. It's so fast, I just set the Website to Production Payments speed run WR (4:38.94). Check it out here, I bet you can't beat it (https://x.com/nickslaney/status/1991151978953789614). We started moneydevkit with the goal of making a payment product that anyone can use. With the rise of AI assisted development, the bar to create value online has never been lower, but a simple search of "stripe…

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:…

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.

Show HN: I crafted the simplest way to Gift Bitcoin this Christmas The link is: www.spreadthecoin.com For the past two weeks, I have been building a Bitcoin Christmas(/Happy Holidays) Card company --> and it has just launched (today) at www.spreadthecoin.com . The "Certificate" makes it easy for Bitcoiners to give their friends and family their first Bitcoin (with suggestions on how to spend/use it)! It is meant to play-well with home-printers and can suffice as a last-minute gift idea. I think that Christmas morning/Hanukkah is an excellent opportunity to gift coins to…

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 hey! I'm the co-founder of squads -- a product that makes it easy to see what your friends and top investors are doing in web3. This product was developed out my own frustration trying to get more involved in web3. One of the greatest challenges in the crypto space is figuring out where to start. For some of us, we're lucky to have a friend who can serve as a guide, and we wanted to build a product that would make introducing your friends to crypto a more inviting experience. There is so much alpha and information living on Twitter + Discord, but the problem is finding the signal from…

Hey HN, I'm a crypto enthusiast who got tired of spending hours researching different crypto credit cards across dozens of websites. After struggling to find comprehensive comparisons myself, I built CryptoCardHub to solve this problem for the entire crypto community.
