Sending ecash on Nostr has gotten really easy. You just paste the Cashu token in a DM, and receiver clicks the Redeem button. It automatically transfers the sats to the lightning wallet you have defined in your nostr profile.

Alternatively, you can click the middle button and it will open your ecash wallet and you can redeem the ecash directly, or you can click the right button and it copy the token to your clipboard and redeem it with your ecash wallet manually.

It's been very cool watching the evolution of this process.
