Description
Problem
We currently have the dependency github.com/miguelmota/go-ethereum-hdwallet v0.1.1 (https://github.com/miguelmota/go-ethereum-hdwallet), which:
- uses an old signer in its wallet implementation
- was released in July 2021
- had its last commit on July 4, 2022
- and is archived on github (read-only)
More recent commits use a newer signer (capable of signing post EIP-155 and post London Fork transactions. Depending on how the transactions are created this may break the Transactor in wallet/hd/transactor.go.
Proposal
Option 1: Get rid of the hdwallet dependency, since it seems to be no longer maintained.
Option 2: Update to a later commit and fix Transactor such that transactions without a ChainId can still be signed, thus allowing replay protected transactions through EIP-155.
Option 3: Leave it as it is. This option has the least amount of effort needed, but does not protect against replaying transactions on a different Ethereum chain/testnet.
