Minibits now 🔒 locks your ecash to your intended recipient, so nobody can steal it on the way. Locks can expire, letting you recover a mistaken lock after some time. Lock the new release to yourself now!

Here's the new feature on planned iOS release, still in the making.
Very cool!
But now the bottom row of the app is overlapping the system buttons:
For the older US gen: 
You can do that 🤯

- Major upgrade of all libraries, switch to React native's new architecture.
- Planned iOS release-related platform checks and changes for Android.

Is this using nip61 or something custom?
Not yet full nip61, but this feature is one of the building blocks.
Wallet feels smoother after updating. Felt like it was getting kinda slow and janky for a while. Thank you as always!
Nice. Shouldn't this be the default when sending?
What I mean is: if creating a mint, then lock is optional, if sending to a recipient then unlocked is optional.
Not all wallets support it yet. For now if the token is locked to a pubkey of one of the contacts, I allow to send it to that one only (over nostr dm) to limit the risk of error.
