Tired of fancy wallets with ads, fees (lmao), and no control over your network connectivity?

Here it is, the final solution! A script to sign offline with Ledger:

                      ✨_Ledger Offline Sign_ ✨

github.com/ustas-eth/ledger-offline-sign

Back to more serious matters, some copy paste from the repo (please, give it a star!):

What

This is a tool that allows you to sign an offline Ethereum (or L2) transaction using Ledger (tested with Nano X) with full control of the transaction data.

As a result, you will receive a bytecode that you can broadcast when necessary.

Why

It's not safe to take Ledger if you have a meeting or there are cameras around that can catch your PIN. A good solution to this problem is to sign the tx offline beforehand and then broadcast when needed without the risk of exposing your wallet or getting a physical rekt.

I found such simple action quite hard to do with existing solutions (basically what any wallet does minus the network broadcasting). They either don't provide a way to change the derivation path / chain id or throw errors.

Privacy and telemetry

The script doesn't attempt to make any network requests and doesn't need an RPC to work. All the information you enter will not be stored anywhere except temporarily in your terminal.

The easiest way to run the tool is to use:

npx ledger-offline-sign

This command will download and run the latest version of the script from the npm servers.

To broadcast the transaction you can use any public RPC endpoint (see on Chainlist) or a web interface like Etherscan or MyCrypto.
