Ledger: gas estimation from Safe is overwritten by Ledger
From Discord:
user on EH Mainnet is having issues with editing the gas price on the advanced options. When user tried to execute the transaction, Gnosis estimated 59 gas price, so he increased it to 65 and when the transaction went through it dropped to 51. Why does the gas price changed to a lower value even though it was set at a higher gas price?
User was using Ledger Nano S, updated to the most recent firmware (2.1.0)
He said he never had this issue before, only recently.
I suspect this isn't Ledger specific. I'm using a Trezor One, overrode the gas price of over 200gwei under advanced to be about 80gwei. I did not notice that it had ignored my override and submitted a transaction with the larger default fee. Confirmed this happened again, and it showed the wrong (unoverriden) on the Trezor screen.
TL;DR: Our estimation is not being passed to the ledger, some oracle is estimating for us when the tx reaches the device
In ETH mainnet, I tried to artificially set it 70k gas limit and 200 Gwei for an estimated 0.014 eth fee, but the leger showed a number more close to the initial estimation of 69300k gas limit and 90 Gwei for an estimated 0.0062 eth fee
I tried the same in rinkeby. There we estimate with the values that the oracle returns for ethereum mainnet, but in reality 1Gwei is enough price for any transaction, so what you can see in the ledger is an estimated fee taking the Gwei price of 1, instead of the price set during the tx review.
