Add support for EIP 1559 Dynamic tx using ledger

I am not sure if this is need for DynamicTx. Does this bug exist in DynamicTx too or it only exist in EIP155?

The workaround can be left in place for all tx types. It's just a way of modifying the transfer so it doesn't trigger a certain bug in the firmware.

@fjl this doesn't seems to work for other tx. This could very well be due to the way typed tx are formed.

if tx.Type() == types.DynamicFeeTxType { if txrlp, err = rlp.EncodeToBytes([]interface{}{chainID, tx.Nonce(), tx.GasTipCap(), tx.GasFeeCap(), tx.Gas(), tx.To(), tx.Value(), tx.Data(), tx.AccessList()}); err != nil { return common.Address{}, nil, err } // append type to transaction txrlp = append([]byte{tx.Type()}, txrlp...) }

I am not sure how to handle this bug here.
Ledger throws error

transaction type not supported

So, I was going to ask you to show some snippet from ledger-docs or something, to demonstrate that they do accept this format, where you prepend the type into the payload like this.

But, seeing as the ledger throws transaction type not supported -- doesn't this mean that this PR is moot, and that the ledger (at least with the software version you are using) does not support signing non-legacy transactions?

@holiman So the error transaction type not supported appears when I apply for ; len(payload)%chunk <= ledgerEip155Size; chunk-- logic for non legacy tx. If I don't do it - Ledger signing works. I have tested with my Ledger nano S. Let me find relevant ledger code

Here you go @holiman https://github.com/LedgerHQ/app-ethereum/blob/develop/src/ethUstream.c#L300 - from what I understand it supports it.

I am also not sure why the ci test is failing. doesn't seem related? How can I rerun it?

shrimalmadhur · 2024-07-20T06:35:49Z

Hey @gballet I saw you assigned this task to yourself. Wondering when you can take a look at it?

fjl · 2024-08-29T07:59:13Z

@gballet was assigned because he has a Ledger to test this with.

Yeah I also have a few, for testing, so I can also give this a spin

awesome! thanks. let me know how your testing goes.

First attempt, invoking signTransaction, I get to verify the details on the
ledger, and click Approve. Then an error occurred:

> eth.accounts // trigger derivation
> acc="0x9858EfFD232B4033E47d90003D41EC34EcaEda94"
> eth.signTransaction({from:acc, to:acc, value:1, maxFeePerGas:1, maxPriorityFeePerGas:1,  nonce:0 , gas:1 })

> eth.signTransaction({from:acc, to:acc, value:1, gasPrice:1, nonce:0 , gas:1 })

After fixing that, it now works. Below is testing with type 2 and 0 (legacy):
