Nostr Web Client

Quick video previewing a feature I've built for Cashu.me that lets you quickly and easily create and redeem a Cashu token locked to an npub.

The first 20 seconds shows how you can easily create a token that is locked to an npub.

It then shows how you can import your nsec into your wallet as a P2PK key in order to redeem tokens locked to your npub.

NOTE: The feature isn't live yet, and may get tweaked before release, but am pretty excited by it.

Is this built with cashu-ts?

Do you have code you can share so I can try this too?

Is it secure to put your nsec (only handled locally on device)?

You can download and play with my fork of cashu.me:

https://github.com/robwoodgate/cashu.me

The nsec feature is in the nsec-p2pk branch. The locking to npub feature is in the npub-p2pk branch.

Hopefully these feature branches will get pulled into the main Cashu.me wallet at some point soon.

Adding nsec directly is a bit "old school" - signers are preferred - but is generally safe if you trust the app (eg 0xchat) or it runs on local browser only (eg Cashu.me / Nostrly Cashu redeem).

At this point, due to the way signers and Cashu mints operate, you can only unlock a P2PK with the private key itself (eg nsec)
