Mitigation to support Ledger hardware wallet

[gre]

I've been able to use Ledger hardware wallet with the Kusama application in combination with Chrome's polkadot{.js} extension support.

• I've been able to see my account
• I've been able to mint a collection
• but as soon as I tried to mint a NFT in that collection, i got an error "not supported"

It seems that this bug relates to limitation of the current Kusama Ledger nano app: the device does not fully support batching yet (it could happen in future, but still, signing huge things with a ledger will not be easily possible).

I was wondering if we could consider a mitigation on the web app side, ultimately it's a decision to bundle all operations or make multiple calls, and it could help Ledger hardware wallet support.

Thanks a lot, gre

Hey, I would love to support Legder in KodaDot.

Yeah you are right we would have to split operations into multiple transactions.

P.S. Is it possible to get a Ledgder testing unit?

// Dev Looks like it is possible to detect origin of the account

So v5.90 supports utility.batchAll however the latest app on Ledger Live is v5.30.1
