I can answer on the technical side (Ledger Nano) since I am involved here.
I posted an update on Ledger Nano a few days ago on the relevant thread: [Soft Launch] Improved IC Staking Documentation and Experience - #19 by diegop
TLDR:
- Ledger Nano team is still reviewing the integration so not available for consumer-facing version
- the ICP integration is available on Ledger Nano’s developer mode (and has been for 4-6 weeks)
- I have not updated docs to reflect this because I want to make sure Leder promotes it to consumer mode.
- I post weekly updates on the staking thread: [Soft Launch] Improved IC Staking Documentation and Experience - #19 by diegop
