Building the Bark plugin for @BtcpayServer, I keep spotting things to improve. I don't ignore them, I open a PR. 4 PRs merged upstream so far. It ain't much, but it's honest work 🧑‍🌾

Banks make you fill out forms, wait in line, and ask permission to use your own money. Bitcoin doesn't. And with Ark, it's instant. ⚡

What if your bitcoin wallet started with just 2 things on screen? Everything else shows up only when you need it or when you turn it on. No channels. No liquidity to manage. Self-custodial.
