What is Kaspa NG and how does it relate to KDX and the legacy web wallet?

Kaspa NG is the official successor to both KDX and the legacy Kaspa web wallet, combining their functionality into one modern wallet. It can run two ways: as a desktop application you download and install, or as a web service you access through your browser. Importantly, it supports multiple seed phrase formats, including the older 12-word phrases originally generated by KDX or the legacy web wallet, so existing users can migrate without losing access to their funds. Understanding this matters because choosing the desktop version gives you a self-contained wallet under your full control, while the web version stores your keys in browser local storage — meaning if you lose your seed phrase, recovery is impossible.
