Three years ago, around this time, I was deeply immersed in an “open-source” attempt to replicate Boltcards – the hot new NFC product at the time from the KYC service CoinCorner. In the end, I pulled it off – likely the first DIY Boltcards, specially made for the @ChainCampCZ 2022 conference. And later, also an extension for @npub10efc...aeh3. 😅 image #throwback @buzzbot 5000
