Share BTC with others. Onchain.

I love bitcoin. I built a DIY project on a raspberry pi called PiSwapL2.

Pass out BTC to friends or strangers with these microSD cards. I pay $1 a card. 3D print the SD card holder for free. NFC sticker has the address. The microSD card has the private key. The raspberry pi automates everything in 30s, from new chip, sent USDC, then swap to either wBTC or cbBTC via uniswap contract. Gas costs 2 cents.
