Your crypto never dies with you

   If you lose your memory, how to regain access to your computer?▲402

   Due to bike-induced concussions, I've been worried for a while about losing my memory and not being able to log back in. I combined shamir secret sharing (hashicorp vault's implementation) with age-encryption, and packaged it using WASM for a neat in-browser offline UX. The idea is that if something happens to me, my friends and family would help me get back access to the data that matters most to me. 5 out of 7 friends need to agree for the vault to unlock. Try out the demo in the website, it runs entirely in your browser!

    Meemaw – Trustless and grandma-friendly wallet as a service▲29

    Hey HN, Marceau here, founder of Meemaw. I was working on a different project (communities with better aligned incentives) for which I needed users to have access to a crypto wallet. I couldn't afford users to have to deal with private keys and what not, and I did not feel comfortable being locked to a non-transparent third-party provider for something as important. So I built an internal "wallet-as-a-service" around audited librairies. I dropped the original project since then and that service evolved into Meemaw. Many "web3 projects" would be better off without any web3 component. But if…

    A "Buy Me a Coffee" Button for Crypto Donations▲14

    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.
