on redeem.cashu.me it is as simple as pasting the LONG string I posted, and then pasting a receiving LN invoice.

minting the ecash is basically the opposite. tell the mint how many tokens I'd like; it creates an invoice to be paid. after invoice paid, press "mint". satoshis become spendable ecash.

NOTE: this is not production ready software and probably has bugs. but it's fun to play with 😂🤙
