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.

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.

In Decentralized Finance (Defi), you can build your own financial instruments and you often need an oracle to write off-chain prices onto the blockchain. We built an oracle focused on data feeds because the current options are too expensive and slow for regularly, repeating data. This oracle is designed for price feeds and uses public key encryption to validate the data submitted is accurate. We modeled our oracle off of MakerDao and generalized the design to work with any datafeed. We’re…

Hi HN! Ben here from hyprsqrl, and I just open-sourced something we’ve been quietly running in production: *hyprsqrl is a self-hostable bank.

Fintechs like Revolut help—until their pricing changes or a regulator knocks. hyprsqrl aims for the resilience of self-hosting *without* forcing users to study crypto. Two…

Hey guys, I built this platform out to allow users to passively earn crypto for non-intrusive highly targetted ads. One of the things that's awesome is that there's an option to receive payouts in Anthropic's pre-IPO stock (via PreStocks on Solana). So you can use Claude Code and receive Anthropic stock . Let me know what you guys think. Feedback is welcome and please give it a try to install.
