Not sure who else is using a Ledger but this may be relevant to anyone that has sent ZEC tokens to this device a while ago.
I couldn’t locate the mnemonic of my ledger but still have the device available, so out of precaution I have purchased a new one so I could transfer the funds to a ledger where I would have the mnemonic details safe and secure.
However, those funds are apparently stuck on the ledger with no way of getting them out. I have contacted the support and this is their answer:
Please note that Zcash (ZEC) app does not support signing transaction versions 1, 2 and 3. It only supports versions 4+. We are currently working on the integration of transaction versions 1, 2 and 3 in the Zcash app.
Trezor was working on shielded transactions, until they weren’t. I am certainly concerned that Ledger may potentially follow the same path for any number of reasons. For that reason I have reached back to them to ask for more details, and they have answered the following:
I understand yoru concern, the team is already working on the integration of older transaction versions. But I don’t have any visibility on when the Zcash app will be integrated.
On my side there’s not a whole lot I can do now aside from being extremely careful with my current ledger device, as well as cross fingers. For those not sure if they may be affected by this, it may be worth checking if you can transfer your tokens out of the device, particularly using the oldest UTXOs (using the Coin Control feature).
