Coinos.io is a web-based, non-custodial wallet that seamlessly integrates Bitcoin Lightning payments with the Nostr ecosystem. It generates a Lightning address (e.g., you@coinos.io) and a Nostr public key from the same seed, unifying your identity and payments. More over you get as well a NIP-05 address, same as your LN address: you@coinos.io

Its simplicity for users and powerful tools for merchants make it our top pick for January 2026. For optimal security, pair it with a hardware signer as your stash grows.
