Bolt Ring

The BoltRing is a DIY contactless payment ring that uses Bitcoin's Lightning Network. Users can pair the ring with their own Lightning node or a custodial service like CoinCorner or a self-hosted service like the Bolt Card Wallet or LNbits. CoinCorner offers the easiest setup, especially for iPhone users. The Bolt Card Wallet allows connection to self-hosted or public Bolt Card Hub services. LNbits provides a free, open-source option with a Bolt Card extension. The BoltRing is compatible with the LUD-17 LNURLW standard, and payments can be accepted by various wallets and POS systems, including Breez Mobile, BTCPay Server, LNbits TPoS, Wallet of Satoshi, and CoinCorner Checkout. Users must back up their keys to reconfigure the BoltRing. More information and purchase options are available on the Bitcoin Ring website.
