A great write up about LDK challenges and why they moved to Breez. All of these we also ran into and solved:

1. Custom rust library around LDK

1. Rapid Gossip Sync bugs and slow syncing

2. Unreliable routing algorithm

3. Concurrent device access w/ just seed word backup

If you would like advice building on LDK or would like to use our MIT libraries to assist in the development of your wallet, please reach out.

We're a small team of 3 people but happy to help in any way we can.
