ledger-polkadot's Issues

Error on connection with ledger

Hello.
When I want to connect my ledger to polkadotjs, I receive an error. ( same error on chrome extension and on https://polkadot.js.org/apps/#/accounts )
My ledger is updated, and also it is on polkadot application, and the ledger live is closed.

Can you help me please?

Can't set onchain identity.

Ledger Nano X + Polkadot Version 25

Allow dev mode

For testing purposes, it would be great if we could install the app with a custom prefix. This would allow for testing it with custom Substrate chains that merely differ in SS58 prefix, enabling projects like Subsocial, Phala, and others to test for Ledger compatibility as well. Likewise, it would allow developers to test with the locally running --dev chain, making development much easier.

Wording improvements

In order to stay consistant with existing apps, could we:

• (kinda duplicate from #50) use 'Amount' instead of 'Value' in 'transfer keep alive', 'unbond', 'rebond' and 'bond' operations
• (kinda duplicate from #50) use 'Amount' instead of 'Max additional' in 'bond extra' operation
• change the 'u' of 'unbonded' in 'Withdraw unbonded' to a capital 'U' (since the term is specific to DOT, our team to bring attention to it by capitalizing it)

Ledger error: Unable to reset the device

Related to polkadot-js/apps#4049

There is an issue introduced by the latest Chrome version

The workaround/solution as described here (polkadot-js/apps#4049 (comment)) is:

going to chrome://flags#new-usb-backend and disabling it

Ledger cannot connect to polkadot.js

I cannot connect to the Ledger and access my funds.

"No compatible devices found".

The Ledger appears when on the home screen, but if I try to connect in this state, I receive the error "Access Denied". As soon as I open up the Polkadot app it disappears from the WebUSB list.

I have tried Chromium and Brave. The Ledger firmware is up to date. The Polkadot app on the Ledger is up to date. Ledger Live is not running in the background; nothing else is trying to access the Ledger.

Hide Tip when zero

Do not show Tip when the value is zero

Catch when trying to access the app while the device is locked

It would help the UX to have something implemented like in BTC app to ensure the device is unlocked before trying to initiate a transaction.

For "Withdraw unbonded" tx, display the "Num slashing span" screen in expert mode only

It's all in the title.

As this parameter is very technical it will confuse most users so we should keep it in expert mode.

Transfer not allowed

Hello, I installed your application on Ledger Nano X: "Polkadot_sec".
I successfully received several DOT, but I cannot send it. Error: Not Allowed

UX fail: Ledger live doesn't show a QR code of the recieve address

Without a QR code you're forced to read AND type the address to recieve manually and that's pretty error prone... so pretty please from a usability perspective can we have this? My friend with the ledger and the dots was very worried she might have mistyped something and sent it to the wrong address.

Allow `proxy.proxy`

Hey!

I noticed that proxy.proxy calls are not currently supported. I use them frequently as part of my workflow and would love to be able to use this application.

I expect that much like utility.batch calls, the UX on signature approval can be pretty difficult / frustrating. I outlined some ideas on improving this flow in #16.

Additionally, I think the proxy.proxy approval process can be limited to approving the standard fields of the embedded call and additionally approving the signing address.

Improvement: Remove trailing 0

In some flows (at least 'Transfer keep alive' and 'Withdraw unbonded'. I'll try to review and list all flows that are impacted), the 'Value' screen displays trailing 0s after the last significative digit. It would be easier to read if we removed them

Is `ledger-polkadot` hardcoded to support only Polkadot, but not other testnets like `Westend`?

I use the @ledgerhq/hw-app-polkadot library to sign payloads for transactions. Code below works on Polkadot:

  const { block } = await api.rpc.chain.getBlock();
  const blockNumber = block.header.number.unwrap().toNumber();
  const blockHash = (await api.rpc.chain.getBlockHash()).toHex();
  const genesisHash = (await api.rpc.chain.getBlockHash(0)).toHex();
  const metadataRpc = (await api.rpc.state.getMetadata()).toHex();
  const runtimeVersion = await api.rpc.state.getRuntimeVersion();
  const specVersion = runtimeVersion.specVersion.toNumber();
  const transactionVersion = runtimeVersion.transactionVersion.toNumber();
  const specName = runtimeVersion.specName.toString();
  const ledgerAddress = (await getLedgerAddress(ledgerInstance)).address;
  const { nonce, } = await api.query.system.account(ledgerAddress);

However it doesn't work on the testnet Westend. The same code throws error "Txn version is not supported". If I hardcode the transactionVersion variable to be 6 which is the number on Polkadot, it throws Unexpected buffer end.

Is ledger-polkadot hardcoded to support only Polkadot but not testnet like Westend?

LNS: Cannot go back previous 'APPROVE' once 'REJECT' is reached

On any flow on nano S, once the 'REJECT' screen is reached, you cannot go back further than 'APPROVE' even though the left arrow is displayed. If you only scroll until 'APPROVE' you are able to go back left without issue.

Modify sign workflow

The signing UI/UX should allow going back to review.
Additionally, all navigation should be horizontal.

Use seed generated by polkadot.js or subkey in Ledger devices

Hi Juan or Natanael,

I would like to derivative on my Ledger the same public key address generated on https://polkadot.js.org/apps/#/accounts

I have imported the seed (24 words) to my ledger. Then I clicked the button "Add Ledger" at Polkadot JS APP. Do you know which account type and address index do I need to select?

Thank you in advance.

polkadot.js question

So I have a bit of an issue. I attached my ledger in polkadot.js, and if you don't have "only this network" checked for the account, it apparently adds that account across all networks, but with different addresses. Under Kusama, it shows this polkadot account but with a Kusama wallet address, so I accidentally sent KSM to this address. But my problem now is when I have Kusama open I cant sign the transaction to send them to another wallet, with my ledger, because its wanting me to open the Kusama app in my ledger. But that is a different account with its own set of private keys. What I think needs to be done is, I have to sign the Kusama transaction with the polkadot app on the ledger, since that wallet has the private keys for the Kusama wallet I sent my KSM too. I hope that wasn't too confusing, its a bit difficult for me to explain, since I am fairly knew to this technology. Any help or info would be appreciated on what to do next.

Thanks.

Session.Setkeys (Not Supported)

Good day,

I am trying to submit my session_key to a stash in which both the controller and stash accounts reside on the ledger. When I attempt to do so I receive an error that session.setkeys isn't supported. I have successfully used this extrinsic on Kusama.

My app version is 6.28.0

Any help would be appreciated.

Ledger app issue

I have tried installing the polkadot app on both a Nano X and Nano S (apps successfully installed on latest firmware) using Ledger Live. However, on both devices, the app crashes a few seconds after opening it on the Ledger device.

Question: Trying to make app work with dev chain

In the pursuit of using Ledger wallet for our Substrate chain (a fork of node-template), I tried making it work with our dev chain. With mostly chain-specific (decimal count, genesis hash, etc) modifications to the app as shown in this commit and polkadot-js apps UI (details of the modifications in this issue if you care), I was able to get a Ledger account added and a balance transfer done but I had to comment out the following lines from _readTx in parser_iml.c as you can see in my commit.

if (c->offset < c->bufferLen) {
    return parser_unexpected_unparsed_bytes;
}

From what I understand, this check ensures that the app is not getting any extra data in the transaction that it is not expecting, is that correct?

• Can there be any bad implications of not having this check?
• Any pointers on how to find out what extra data is being sent that the app is not expecting? I am able to get the raw txn bytes sent from the browser but don't know how to debug in the app itself?
• Don't have much exp. with C or hardware programming so any pointers would be helpful.

Ledger Live Staking Issue

Stash account is a Ledger account. Controller account is injected from the Chrome extension to Polkadot.js. Everything works fine with staking. Then when Ledger Live support for Polkadot was released today with staking, I wanted to "move it over" to Ledger Live. I added the Polkadot account via Ledger Live and voila, the stash account appeared but the controller account did not because the private key is not on my Ledger -- makes sense.

Because of this, Ledger Live does not let you manage your stash account because it is controlled by a non-Ledger controller. But, you can view the stash account on Ledger Live and see the transactions, etc. It all seems to be working fine if you want to let it ride. But if you want to make any changes, it doesn't seem like I can do it from Ledger Live.

Attached is a screen grab of the message displayed in the Nominations portion of the account page on Ledger Live. Instead of giving access to nomination features, it displays this message.

I am wondering what my next step should be. Create a new controller on Ledger Live and control the stasher that way? Unbond and start again on Ledger Live? Thank you!

Upgrade to v7.x.x

Reduce app size.

Hi, it would be great if I could use the Polkadot and Kusama app on a Ledger Nano S.

Atm the Polkadot and Kusama apps take 112 and 120 kb which is 232kb. The Ledger S has 156kb capacity.

Is it possible to perhaps tweak with compiler flags, strip stuff or optimize the apps to fit both on a Ledger Nano S. This would be great, bc. I think it a common app combination users want to have on their Ledgers.

I looked in the code and saw that the rust-app gets built with debuginfo (maybe stripped later i.d.k.). Or twiddling with the panikhandler to save some bytes. Use the z optimisation instead of s....

Address derivation details of Ledger app

I have my own hd wallet implementation for Polkadot that developed with C#.
I used Bip32-Ed25519 for addres derivation like in Ledger (I guess)

My implementation has the same results with test vectors here;
https://github.com/satoshilabs/slips/blob/master/slip-0010.md#test-vector-1-for-ed25519

I can also confirm that addresses I generated from privates keys that generated by my code, also matches with official Polkadot wallet Subkey.

But my addresses doesn't match with Ledger.

The values I got from Ledger:

// 15fn3g9Ehu9FYTBUSzWPihcVfHnfm2AfFNtMtPNMHGkoWTEg m/44'/354'/0'/0'/0'
// 1446qjMShfFgAtGzsLd5ykqC5cHXXDumcbNbPQTd9ZHsoePY m/44'/354'/1'/0'/0'
// 13KpDbPsYHBsT8YDCP3LaDbZkKaTUMXQq4tM8y7hrYD2Hq6m m/44'/354'/2'/0'/0'
// 14qrzk2kjH4gfs4Q2PCEKy6pWS3JeqHkEcvP3TFASm4mVtAW m/44'/354'/0'/0'/1'

with mnemonic
identify fatal close west parent myself awake impact shoot wide wrong derive ship doctor mushroom weather absent vacant armed chuckle swarm hip music wing

From that mnemonic, I am generating the seed;
fd18bdbc7382ea5356efef894d30dd3676a7ce37072e7947dd7e9076f9dd15b829b51d4d5fe9de7364f8dd6ad2c05320d942c69f3aebbad9228395e472d27a35
(also matches with bip39 )

Difference starts here.
address-path pairs I got;
Path: m/44'/354'/0'/0'/0', address: 13HTSwVwT5zCvTSho2RFGkmm5B2PE7aY4WnFpvUikYLTE2La
Path: m/44'/354'/0'/0'/1', address: 12bhKwEky1hjSnsyQhvfXawCirC7UMpQXvkYRcJVP2T9TYwA

Path: m/44'/434'/2'/0'/0', address: 158Mt8CRsJPNz3XGNpHEBvPAqq5tFkzFK5KCN5hHzV8gtWPS

I am not sure what I am doing different that causes this issue.

Can anyone lead me to the right direction, maybe give more details about Zondax's Polkadot wallet implementation.

How does the actual ed25519 derivation work

So I have an issue logged from a user around supporting Ledger seeds as an import. Generally this is not such a great idea since you really want to keep the secret safe and locked up.

Having said that, addressing it will also be self-serving for me - i.e. I just had a little episode in which I had to replace my Ledger and while waiting for a replacement (6+ weeks) didn't have access to that specific stash at all. So at least in my recent experience there is an argument to be made that keys should be derivable in a couple of places. (Not available/exposed, just the tools should be there)

So this brings me to how it is done on the Ledger. Did a bit of research and it seems the Tezos (and actual Trezor HW as well) implementation uses the bip32-ed25519. Tested that via others and libraries and it works quite well, but doesn't seem to be compatible with what is outputted on the Ledger.

For earlier posts elsewhere I picked up that (and it may be misleading) that the Ledger does the normal derivation, then hashes the secrete and feeds it into the ed25519 curve when not using the bip25519 approach.

So effectively, from my understanding, the steps are -

• mnemonic -> seed
• derive path e.g. m/44'/354'/0'/0'/0' (assuming account 0 & index 0)
• do something ...
• create a ed25519 secret/public from this as an input seed

Improve amount representation

Make the displayed amounts more concise and display the unit: for instance instead of 2.00000000000 display 2.0

Support transactions on SORA network

Currently polkadot application does not support SORA network. We can on other sends the fund there but once they are there it is blocked. Would it be possible to whitelist this network to be supported by Ledger polkadot application? https://polkaswap.io/#/bridge

UI displays addresses without network prefix

This could be very confusing to users, and might very well cause them to blindly accept transactions (because they can’t do anything otherwise).

code for ledger app not optimized

hi,

fact is at 144K the Polkadot app is FAR bigger than any other app on my ledger. with limited space, it's a dog. even the highly similar KSM app is only 78K, which is also huge and ought to be severely reduced as well.

App does not seem to be open

I can get to the "Add account" UI on polkadot.js.org and clicking save initiates the pin request on the device. After entering the pin successfully it either gives me an indefinite spinner or says "App not open". Looking in the chrome devtools when receiving the error case there is:

main.ed2ca610.js:35 Error: App does not seem to be open
    at a (polkadot.02.784ba675.js:1)

I have the same problem on both my arch linux machine (latest stable chromium) and my Macbook Pro (Google Chrome 86.0.4240.111)

Here are the versions on my Ledger Nano X device:

Polkadot app version v5.23.0
Firmware version: Secure Element 1.2.4-5 / Microcontroller 2.10 / Bootloader 1.4

This used to work fine before upgrading the firmware. Upgrading the firmware triggered an app reinstall, so I can't check the polkadot ledger app version I used to have unfortunately.

Upgrade to Polkadot 12

Let's remove it.

'Unexpected Value' when trying to sign a transaction

Not sure where it is best to report this, but basically when trying to trigger a simple balance transfer from the Polka JS interface it seems like the Ledger App app replies Unexpected Value. Tried to debug this without much success. I believe it also happens with Kusama.

Both the Ledger (X) and Polkadot apps are up to date.

Allow `utility.batch` calls

Hey!

I noticed that utility.batch calls aren't currently supported in this application -- I've been using these in a lot of places and would love to continue using them.

I understand that utility.batch calls have the potential to introduce a lot of complexity in the signature approval process -- I think this can be improved by:

• Rejecting embedded utility.batch calls
• Limiting the number of calls in a utility.batch to a fixed constant (e.g. a max of 20 calls could be added)
• Allowing some process to configure which fields require an explicit approval (e.g. some users may not care to approve the spec version)

UX improvement

The current app is named Polkadot, but we still display the chain in non expert mode.

Would it be possible in non expert mode to:

• Remove the chain screen and not allow to sign for other chain (as discussed on slack)
• Change 'Value' with 'Amount' (To match the other Ledger apps)
• Add the Unit 'DOT' before the amount value (To match the other Ledger apps)

Any way to customize the derivation path format?

Currently polkadot portal only allow derivation path in //019//019 format
But most people may come from parity signer, which use //polkadot as the default derivation path
I think it would be great if there's a way to use a user-specified derivation format
so that those who came from parity signer can use the same seed on a ledger, rather than unbonding funds and wait for a month then transfer to the new wallet.

Can not sign transactions - Spec version not supported

Ledger - Polkadot Setup Issue

I am attempting to set up Polkadot on my new Ledger Nano X. I have followed the step to "Add Ledger", and Add Account Via Ledger (selecting Account Type 0 twice), and I click Save but the app crashes at that point and does not add the Ledger account. I tried this several times, and yesterday it did add the Ledger account and I was able to transfer 1 DOT to the account, but today the Ledger does not show as an account and the file is crashing when I attempt to reinstall. I am glad I only transferred 1 DOT rather than my full DOT balance. Any suggestions on how to remedy this problem?

The Polkadot page also displays:

One of more extensions has been detected in your browser, however no accounts has been injected.

Ensure that the extension has accounts, some accounts are visible globally and available for this chain and that you gave the application permission to access accounts from the extension to use them.

Generating addresses for Polkadot outside of the ledger.

Hello!

BIP 44 defines how addresses should be derived. But the current workflow documented for Polkadot here is very evasive about the account type and address index meaning.
I would like to reproduce the addresses generated by the ledger outside, for instance with Subkey. I would expect that something like mnemonic//44//354//0/0 would reproduce the ledger address obtained with setting both the account type and address index to 0 for instance, but it does not seem to be the case. I tried to mix different soft/hard paths, or to add a coin change placeholder to the path, but it did not help.
Could we get the formula that translates a ledger derivation choice to a subkey formatted command?
Thanks a lot.
