I have created a 2/2 multisig wallet using the Gnosis Safe with one of the signer being a ledger hardware wallet.

I have done 2 tests:

  1. The ledger is the first to cosign, then the ledger screen will display a rather cryptic transaction hash and ask for validation

  2. The ledger is the last to sign, then it will ask me to validate the amount (incorrectly displayed, I wanted to transfer 0.2ETH and it was displaying 0) and the destination address (again, showing incorrect data and not the address I was sending my transaction to)

So either it shows (1) no relevant information regarding the transaction or (2) incorrect data - is this a known limitation using Gnosis Safe?

I will quote the answer I got from the Gnosis team on their discord:

For 1 the web app requests to sign a message and ledger displays a hash of a hash of that message (this is a ledger ux issue). For 2 you are signing a contract interaction that triggers a transfer from your safe, therefore ledger will not display it. Ledger would only display it if you transfer funds from your ledger account.

Proper display of contract interactions are a shortcoming of ledger, it would require support for eip-712 from ledger to improve this to some extend, but this is out of our scope as it requires changes in the ledger firmware

I think most hw currently have similar limitations

Really bad news at it means HW are pretty much useless with Gnosis Safe
