After a few years, can't open ETH (Ledger Nano S)
Also, this could have some helpful info.

Anyway to generate staking keys using Ledger for solo stakers?
I've been looking at different documents like Ledger Hardware Wallet ETH JavaScript bindings and I don't see anything for this.

For those interested in the text details, here's a ledger bug thread.

How do I connect to the Ledger Live app over Websocket?
Here's a minimalistic Python implementation I'm using on my system https://gist.github.com/btchip/85b4018f0c421bd72c8f818ec31c69ef - from the client side of the bridge you can just use the HTTP transport of ledgerjs (https://github.com/LedgerHQ/ledgerjs/tree/master/packages/hw-transport-http). However I wouldn't suggest to use the bridge and rather focus on a native webhid/webusb implementation as the user experience would be much smoother. You can have a look at this Metamask fork to see how it's done https://github.com/hectorchu/metamask-extension , or Keplr https://github.com/chainapsis/keplr-extension or Terra Station https://github.com/terra-money/station

[Ledger Nano S] ETH 2 Deposit Not Recognized?
You can generate the keys, but you can't sign with them at the moment. There's no tooling available yet, just some low level documentation https://github.com/LedgerHQ/app-ethereum/blob/master/doc/ethapp.asc#get-eth2-public-key and a third party services integrating it in a web application using https://github.com/LedgerHQ/ledgerjs/blob/master/packages/hw-app-eth/src/Eth.js#L1023, such as https://stake.fish - you might be able to get the withdrawal key from there by going through the process without confirming

Calling into ledger programmatically
If you're fine with Javascript you can have a look at https://github.com/ledgerhq/ledgerjs which is the most maintained transport library to communicate with the different device applications (f.e. https://github.com/LedgerHQ/ledgerjs/tree/master/packages/hw-app-eth for Ethereum)

Daily General Discussion - May 7, 2021
Here's the relevant code: https://github.com/LedgerHQ/ledgerjs/blob/master/packages/hw-app-eth/src/Eth.js#L360 Specifically what they do is pre-compute two different hashes for the EIP712 message. One is for the domain (kind of like metadata) and the other for the message itself. They then hash these together on the device.
Ledger tried blaming MetaMask for not supporting them yet, saying they had already implemented the EIP-712 standard. We looked at their code base and discovered they weren't generating signatures on the secure hardware at all - they're doing it on your computer and their CTO confirmed it.
The second we saw is that even when it is ready, it's not using hardware security. Here's their code base. Their CTO confirmed our understanding of their code, hence the tweet.

Can Nano S display transaction data?
You have to submit the signed token metadata before signing the transaction - this is done by provideErc20TokenInformation in https://github.com/LedgerHQ/ledgerjs/blob/master/packages/hw-app-eth/src/Eth.js if you need a sample

WTF is up with ETH gas fees!
Gas fees are not at 1000 gwei all the time, as some screenshots might suggest. You can see the historic average gas price on gasnow.org

Daily General Discussion - October 2, 2021
Yesterday someone posted about alternatives to gasnow.org since they are calling it quits. The gas estimator service from Blocknative (blocknative.com/gas-estimator) was mentioned.

25th word - expense calculation
There are ways to estimate fees in realtime, such as https://mempool.space/ for BTC, https://www.gasnow.org/ for ETH, etc., if you want to go to the bother. But as above you can pick a low-traffic time such as Sunday morning and you'll probably end up with as low a fee as you're going to get.

what's going on with https://www.gasnow.org/ ?
-
How much ETH do you hold to move your ETH based crypto?
It costs about $5 to move ERC20's currently.
-
If the median ETH gas fee is $10, why are so many people paying $200?
GWEI
https://www.gasnow.org/ lists the estimated cost of different kinds of transactions, including uniswap swaps.
