There has been significant efforts to overhaul it for performance considerations recently. Within a month or two these optimizations should be merged to master, and wallet should be good to go for high throughput uses while consuming small amounts of system resources.
Previously smaller projects I have heard of using it in production.
Ok, thanks for the update. Are you involved in the development (if I may ask)?
Where can I follow this development - is this happening inside conformal? Just curious where to track the progress of this new wallet implementation, and learn about its features.
