Just curious, but Grin does not use bech32 right? So why/where is it needed.
Edit: It is used for the slatepack address😅

There was a PR on grin-wallet regarding some timing constraints with the ledger app. It links to GitHub - NicolasFlamel1/ledger-mimblewimble-coin which could be a useful resource. I’m not sure what the app does or doesn’t or if it even works, just another potential source of information that should not be assumed to be safe as far as I’m concerned.

last update you’ve mentioned feeling a bit of under the weather. I’m going to take it as there is no mention: the no no news is good news approach, plus I hope your feeling near if not all the way back to full super strength. Side note- I can’t wait to run this protocol on some hardware wallets, such a cool idea and important for the peace of mind of storage. Many thanks for your work, good luck to progress and bug free code
