#Bitboard Wallet 0.1.4 comes with minor UI improvements - most notably a slightly more intuitive two level navigation footer. On mobile devices the app should look fine everywhere now. If it doesn't, please contact me. Check it out on

Bitboard Wallet 0.1.3 now supports "amountless" Lightning payments (meaning the payer specifies the amount) via NWC. That version also features some recovery logic for persistent Esplora sync issues. Check it out here:

Under certain conditions persistent sync errors could appear after trying to connect to online blockchains in #Bitboard Wallet (https://bitboard-wallet.com), if starting out with a pre-0.1.2 version. Creating a new wallet under wallet management should fix those. I'm working on a more convenient fix for future versions. These kinds of errors are annoying, but stress the importance of using seed phrases. Using the seed phrase of a "broken" wallet during import is a highly robust recovery path. #BTC

My interests and efforts have been mostly divided between philosophy, science fiction, economics, and software development. I just realized that as Bitcoin developer, I am actually in the intersection of all of that. My latest project:

The Esplora sync issues are finally fixed in #Bitboard Wallet v0.1.2, because I had a nightmare about them and then did a mad 3 hour development sprint with Claude Opus 4.5 (still reasonably priced). Check it out on

If you try the live Bitboard Wallet app (https://bitboard-wallet.com): Connecting with live mainnet, testnet, or signet networks doesn't work due to CORS issues. I tried setting up a small proxy server for addressing that issue, but haven't got that working yet. In other words: A productive solution probably will have to wait until after Bitcoin Conference. Developers can still try running the app in development - there everything works, because there are less moving parts. The main selling point of the wallet should work anywhere though: The simulated "Lab" blockchain. #Bitcoin #Bitboard

Just released v0.1.0 of Bitboard Wallet:

Check it out. The integrated blockchain simulator doesn't even require you to create a wallet. You can skip wallet creation by clicking on Settings and then Lab. Lab transactions are displayed as cards nicely suited for mobile devices. #Bitcoin #Bitboard

There's a new Bitcoin PWA wallet in town: **Bitboard Wallet** ⚡

It's not just another wallet — it's built as an integrated Bitcoin learning and onboarding app: • A clean knowledge base called the Library • A hands-on tiny blockchain simulator the Lab — create users, mine blocks, send real-looking transactions I built this to help more people go from zero to deep understanding of Bitcoin and Lightning. Right now it supports Lightning via NWC (easy to connect). A full integrated Lightning node (Mutiny-style) is already planned. This is a very early beta (only 7 weeks old, built agentically with Cursor). The codebase is a bit messy from the rapid pace, but the product feels solid for a demo. Non-custodial, open-source, PWA — installable on web + mobile. If you're into Bitcoin education, self-custody, or just want to play with a blockchain simulator, check it out and let me know what you think! #Bitcoin #Lightning #NWC #BitcoinWallet #PWA #OpenSource #BTC

I just committed my Cursor rules to my portfolio base repository. That does feel like a futuristic milestone. There's no going back from this:

My flight to Bitcoin Conference 2026 in Las Vegas starts in almost precisely 2 months. It will be my first time visiting that convention, Las Vegas, or the USA. I will arrive very early and leave very late, so that I can spend 10 days in Las Vegas. This feels like a significant step since I walked out of my last full stack dev job. I've been doing a dedicated deep dive into Rust, Bitcoin, Lightning, Nostr and agentic development for the last three months. My plan is to demo an educational Bitcoin and Lightning wallet there - mostly informally. So far, I've remained in brainstorming and planning mode on that, as I am still focused on optimizing my agentic development setup with Cursor. I don't call myself a vibe coder. What I aim to do is "clean agentic coding", which is challenging, because agentic code tends to be quite messy without serious guardrails. Agentic workflows that produce clean, correct, and maintainable code are possible, but it does take some time to set them up properly. Anyway, this is just an early announcement of my plans. There is much more to come. #dev #bitcoin #lightning #agentic #vegas

Getting into Rust and "clean agentic development" as I call it tentatively has absorbed me for the last months - in addition to getting into the Bitcoin, Lightning, and Nostr primitives. I'm planning on turning this first zero2prod-axum project into a CRM for my own portfolio. #dev #rust #agentic

I just found out that Claude 4.5 Sonnet is remarkably bad at simple refactoring and code cleanup. Splitting one file up into two while maintaining functionality turned out to represent a surprisingly difficult challenge for something that is mostly trivial copy and paste for humans. Amazing! #ai #dev

I feel like I've hit the current limit of agentic development - frustratingly early. I was just trying to add some very simple Playwright end to end tests to a React app with a Rust backend. Even after 6 hours of debugging, the success rate of those tests got stuck at around 20%! So much for the skills of Claude Sonnet 4.5 (thinking) in Cursor. Well, back to manual debugging, I guess. At least this has been a very educational experiment. #ai #dev

Really fascinating and useful report! Especially for those who see a job in the Bitcoin space like me! View article →

Yesterday I tried transferring some Btc from my #Binance account to my hardware wallet. In previous instances, that worked. But yesterday the transaction was flagged as high likelihood of a scam. Outgoing transfers were blocked twice for an hour! I searched for similar stories on Nostr during the last 30 days, but didn't find any. What is going on?

Just found this old post, and think that it's still relevant. Do you think the situation on Nostr has changed since back then? Are there any new insights? View article → #v4v

Today I experimented with agentic development with Cursor after purchasing a Pro+ subscription costing $60 US, which pays for $60 US of tokens. The overall experience was relatively good, but checking the usage list made me think again whether Pro+ would suffice for any large project work. Claude 4.5 Sonnet is really good, but burns $ at a rather rapid pace. For easy tasks, the custom AI agent Composer 1 by Cursor is rather sufficient. Also, having long-winded sessions seems to push costs upwards due to ever increasing context. Letting a second agent review what the first agent did and a third agent implement the requested fixes reduced costs to $0.50 for those steps. Compared to the roughly $20 I spent on the actual coding and debugging, that's a bargain. It was just about refactoring a small project to use a different library as dependency. In the end, I didn't need to check the documentations of those libraries. But I needed to check the output of those agents very closely. They tend to drop functionality, if they feel it's difficult to maintain it! #ai #dev

This is deeply fascinating! Economics seems to explain even more than just the parts of politics we usually think about. Long read, but really worth it! View article →
