A lot of the bindings are the same, because Helix was inspired in part by Vim.

Helix overall tries to make more consistent vocabulary and “nouns” and “verbs” in the keybindings, so there are some breaking changes.

Someone published a more “vim-like” set of keybindings for Helix: https://github.com/LGUG2Z/helix-vim

I started with that and then have slowly disabled a number of them as I come to appreciate the Helix defaults, and have realized that some of these vim-bindings are overriding other Helix bindings that I wanted.
