+        chain_setting=chain_setting,
+        start_index=validator_start_index,


this validator_start_index throws an uncaught exception if the user misenters, you can't tell from the response that this was incorrect and user probably might not know what the right answer is.

Hey @james-prysm could you elaborate on this case more? I tried to input random English and the cli did detect my wrong input and asked for re-input. What was the testing input you used?

I broke it :)

https://gist.github.com/infosecual/d7de7005bf54732a863dce21d503e445

using "1,2,3,4,5,6,7,8,9,10"

as the input to: Please enter a list of the old BLS withdrawal credentials of your validator(s). Split multiple items with whitespaces or commas.:

@hwwhww I totally missed this, put in the wrong validator_start_index with the corresponding validator indexs and it broke.

use case is
using a mnemonic of 1800 keys, 0~1799 index
input for validator_start_index: 1
validator_index: 0
withdrawal_credentials: 0x004652a99d8c9278708a98dab2c09b45cf09ea732037a17583ae2513a329fd8a

i get the following error
File "staking_deposit/utils/validation.py", line 246, in validate_bls_withdrawal_credentials_matching staking_deposit.exceptions.ValidationError: The given withdrawal credentials is matching the old BLS withdrawal credentials that mnemonic generated. [76365] Failed to execute script 'deposit' due to unhandled exception!
if i used validator_start_index:0 it works

can both non hex and hex be handled? or if the error for non hex lets the user know,I believe some users will get the withdrawal pub key from the intial deposit.json which doesn't have 0x

bls_withdrawal_credentials_list can be with 0x prefix or no 0x.
eth1_withdrawal_address requires the checksum form and 0x prefix.

@hwwhww Does this mean if the user pastes an all lowercase address it will be blocked?

@wackerow
in a very edge case, an all-number address is a valid checksum address 😄 but I understand what you mean, yes, the input addresses have to be checksummed and capital letters matter.

@james-prysm, per https://github.com/ethereum/staking-deposit-cli/pull/313/files#r1087833602, I made a warning at the beginning.

Hey @CarlBeek It is printed before we select language now because I'm not sure how to print/echo the message before the user input sensitive data. do you have an idea of how to make it translatable?

I don't see an obvious way of doing so, unfortunately

CarlBeek

Fantastic work on this epic PR @hwwhww!

Having reviewed this again, I think we can move to merge this into dev. The core logic seems good to me.

That said, I do think there we need a bit more polish before putting this in front of mainnet users things like:

clarifying the wording around the different types of indices
- stretch goal, we calculate the start_index from the withdrawal credentials
try remove all the eth1 verbiage
Clean up the warning messages a bit, I think we've taken them overboard and users will get lost/numbed

infosecual · 2023-02-20T20:45:36Z

I have a few nit-picky things I noticed while doing a security review, none enough of an issue to stop merging to dev but I figured this is the best place to drop them as this is where the conversation about these changes is happening.

+
+You can use `bls-to-execution-change --help` to see all arguments. Note that if there are missing arguments that the CLI needs, it will ask you for them.


If you try to run the bls-to-execution-change subcommand with --help it will actually skip the help menu and drop right into interactive mode:

user@laptop:~/repos/staking-deposit-cli$ python3 ./staking_deposit/deposit.py generate-bls-to-execution-change --help ***Using the tool on an offline and secure device is highly recommended to keep your mnemonic safe.*** Please choose your language ['1. العربية', '2. ελληνικά', '3.

infosecual · 2023-02-20T21:16:14Z

There may be a reason to specify "mnemonic language" vs. "language" since we have these as two separate fields in the initial validator credential creation:

user@laptop:~/Downloads/staking_deposit-cli-d83c312-linux-amd64$ ./deposit new-mnemonic

***Using the tool on an offline and secure device is highly recommended to keep your mnemonic safe.***

Please choose your language ['1. العربية', '2. ελληνικά', '3. English', '4. Français', '5. Bahasa melayu', '6. Italiano', '7. 日本語', '8. 한국어', '9. Português do Brasil', '10. român', '11. Türkçe', '12. 简体中文']:  [English]: 3
Please choose your mnemonic language ['1. 简体中文', '2. 繁體中文', '3. čeština', '4. English', '5. Italiano', '6. 한국어', '7. Português', '8. Español']:  [english]: 8

When we create the bls change message in interactive mode it might be good to specify that we mean mnemonic language here:

user@laptop:~/Downloads/staking_deposit-cli-d83c312-linux-amd64$ ./deposit generate-bls-to-execution-change 

***Using the tool on an offline and secure device is highly recommended to keep your mnemonic safe.***

Please choose your language ['1. العربية', '2. ελληνικά', '3. English', '4. Français', '5. Bahasa melayu', '6. Italiano', '7. 日本語', '8. 한국어', '9. Português do Brasil', '10. român', '11. Türkçe', '12. 简体中文']:  [English]:

I understand that this is not really a change that this PR made and it is technically inheriting this "Please choose your language" string from the existing-mnemonic work flow. It is just a little more obvious in that workflow since the subcommand contains the word "mnemonic" in it. idk if it is worth changing as it will be obvious it isn’t talking about CLI language after a bit. I just figured I would throw it out there. No strong preference here.

We would probably want to change the --language arg to --mnemonic-language too if we did want to specify. It is possible to confuse the two (see the other use of --language in the default help menu):

user@laptop:~/repos/staking-deposit-cli$ ./deposit.sh --help

Is it planned to support non-interactive usage for the blsToExecutionChange?

There is the --non_interactive flag, had to read the code to find it.
I'm suggesting adding this to the documentation.
Also even with this flag the tool still asks you to press a key when finished, could use some improvement.

…and messages.

Modify the error messages.
Avoiding output of the call stack.

Add prompt confirm requirement to generate-keys module's eth1_withdrawal_address option

Unsolved

The help menu line wrap (Add generate_bls_to_execution_change #313 (comment)): it looks like is deep in click. Might need some overriding work.
Remove all the eth1 verbiage: I have another WIP branch that tries to make --eth1_withdrawal_address be the alias of --execution_address. It works, but I am worried that, in the case that user somehow types in BOTH --eth1_withdrawal_address and --execution_address, click by default will override the previous with the latter. Will open another PR for it.
@CarlBeek's suggestion: Calculate the start_index from the withdrawal credentials.
