Key facts
- Magazine, Eivydas Račkauskas, Chief Orange Pill Giver at Wavespace, said that 70% of the payments made on the platform use the Lightning Network and that the company is looking into the ARK protocol
- This protocol, documented in NIP-47, allows users to connect a service like this debit card to a self-hosted Lightning node
- Wavespace has been almost entirely bootstrapped and self-funded, according to Račkauskas, except for an early Relai angel investor who supported them in 2025
- Wavespace’s self-custody debit card solves these problems with a novel Bitcoin technology called Nostr Wallet Connect, or NWC for short
Summary
Debit cards in the Bitcoin and broader crypto industry have traditionally worked by preloading custodial accounts with bitcoin or stablecoins. Wavespace’s self-custody debit card solves these problems with a novel Bitcoin technology called Nostr Wallet Connect, or NWC for short. NWC is a technology developed by the Nostr ecosystem, a high-tech niche within the Bitcoin industry that is branching out into social media and other communication protocols. As a high-tech neobank, Wavespace gives users a personal IBAN account, which they can send fiat to, to purchase Bitcoin.
