Impossible to set correct gas price for gas tokens with low decimals about safe-smart-account HOT 4 CLOSED

Hi, @rmeissner
I am also facing this problem, do you have any solution or advise on this ?

I had a weird brainfart and struggled to understand the example calculations, so I'll leave some details for a future reference:

1. The gas price in a token is calculated as gwei_price * 1_eth_to_token_ratio
2. In the example 1_eth_to_token_ratio would be 100, 1 ETH = 100 LOVE
3. The result is 5 * 10^11

My biggest problem was understanding where 1e12 came from. If we use uniswap, then the price 1_eth_to_token_ratio would be calculated as:
price = love_reserves / eth_reserves
where love_reserves and eth_reserves are in their smallest denomination; therefore, if we want to get to their largest denomination, every reserve has to be divided by 10 ^ token_decimals, so we get 10 ^ 6 / 10 ^ 18, which turns into 10 ^ -12.

The example calculation is in the largest denomination, so to get to the smallest, we need to multiply it by 10 ^ -12 which is the same as dividing by 10 ^ 12

if you send tokenGasPrice multiplied by a factor say 1e18 and update handlePayment to divide by this fixed number then it solves the problem.
we tried to keep variable tokenGasPriceFactor but fixed high value also makes sense.
