estimateGas for writing the contract in ethers 6

[moneyDev1111]

Hi, How do I estimaGas for a contract function in ethers >5? In ethers 5 it way contract.estimateGas.contractFunction(), but now it doesn't work this way..... Thank you

[moneyDev1111]

this for example provider.estimateGas(await contract.function()) throws an TODO error...

This will execute the function and pass the result to estimateGas, which is not likely what you want. :)

my bad the example above is the right method I guess, I had a typo in the code

[ricmoo]

contract.someMethod.estimateGas(arg0, arg2)

what is the unit that estimate gas returns ? wei or gwei ?

[ricmoo]

It is in units of gas.

So, for example if you wanted to figure out the maximum fee for a tx with an estimated 30000 gas and a maxFeePerGas of 1 gwei, you would multiple them together: 30000 [gas] * 1 [gwei / gas] = 30000 gwei.

Make sense?

[RasenGUY]

Yes it does
