Add BLS to ETH1 change request

[mbaranovski]

Description

I staked ETH and set the withdrawal credentials to the BLS ones using Ledger device. Shanghai upgrade is approaching, in order to withdraw the funds from my validators I need to update withdrawal credentials from BLS to ETH1. There are some existing guides like this one, but how do I do it on the ledger device?

Your environment

• OS and version - Mac OS
• Device (Nano S, Nano X, Ledger Blue) - Nano S

hi @mbaranovski this is currently not possible, we are looking into it.

Hello, please make it possible in the spirit of the Ethereum-Community. Thank you

@adrienlacombe-ledger please work to make this a high priority within the ledger team in the coming weeks before shanghai. Many of us will be relying on Ledger and Stakefish to work together to make this a reality. Many of us lack the technical ability to do the cli commands ourselves so we are stuck unless something is done.

[adrienlacombe]

@calaber24p I wish I had this kind of power but I don't set priorities at Ledger.

[calaber24p]

@adrienlacombe-ledger At minimum I appreciate letting the team know, I think many of us are just a bit frustrated. Any update on what the team says, or if they decide they will even try and make a fix would be appreciated.

[adrienlacombe]

We know, I understand. I keep you posted.

[ksheni56]

Thank you. From what I read in Ledger reddit channel, the Ledger Nano X already supports BLS signing, so theoretically only the integration for the Ledger Ethereum app would be required? This makes a lot of sense to do I think, and it would be enough for me if we where not forgotten. I like being at "ledger's home" @adrienlacombe-ledger

Thanks @adrienlacombe-ledger ,

It would also be helpful to understand the roughly estimated timeline once known. Many of us have staked and waited a long time already, but just knowing for sure this is a feature that is being worked on, and at least assured it was a feature that is possible so our funds are not locked up forever, would be comforting to say the least!

[adrienlacombe]

@jmspinelli your funds are not locked up for ever, you can always put the mnemonic in an air gapped computer and sign the message there but we would prefer that you don't have to do that. I keep you posted on feasibility for sure.

[jmspinelli]

Ok, thanks. Yes, rather not go down that route, which could be complicated. Not sure air gapped computer method is possible if we used a 3rd party provider such as Staked.US; Stakefish, etc that doesnt hold the private keys (mnemonic) but holds some other component of the keys needed to service the validator.. not like we can access their infrastructure. We'd have to install dependencies for the validators locally onto our machines then?

@adrienlacombe-ledger Unfortunately the way with Ethdo isn't working properly (I try'd it with only menomic-ledger-seedphrase on my airgapped laptop) like @jmspinelli told. I was a bit shocked as a non-tech expert when I got the message from ethdo offline: no validator could be found to this mnemonic, it searched 1024 indices. So I used the Ledger Recovery Check app to check my phrase, and at least withdrawal credentials are on my ledger.

Some people used a hardware wallet to create BLS credentials and are now stuck. Because said wallet can't sign a BLS message. Allnodes (which I used to setup my validator - https://wallet.allnodes.com/eth2/generate) and staked.us did it differently and used a BLS public key from a Ledger.

In theory, as long as we have the validator seed phrase, derivation path (this is likely the piece we are missing), and any passphrase (may be applicable if you used this on the ledger), then it is possible to use ethdo today.

All of this are informations that I've received from inquiries in the Ethstaker Discord channel which I like to share with you, but from what I see there is really no other way to get recontrol to our money around without the help from Ledger Team which hopefully can offer us the BLS signing in the ethereum app. I wish you all the best of luck and hope you can do it.

[adrienlacombe]

@jmspinelli @ksheni56 thank you both for these details, indeed this would require work from the staking services, I will share this with the team.

[ksheni56]

With pleasure, if I can be of any further assistance, please let me know.

@adrienlacombe-ledger
Please accept this as positive criticism as I have been appreciative of Ledger since 2015.
How is the company "Ledger" not wayyy far out ahead of this implementation already in expectation of the Shanghai upgrade? Stake.fish is arguably the industry leader in Ethereum Staking. #SomethingSmellsFishy
