Hi, I need to send all the funds are in te sender account, but didn’t include the gas and fee, how can I estimate it?

Thank you

I am not sure if this is implemented in the JS SDK, cc @milenradkov.chain

Hi @sgcvzla.chain and @Baixin.chain please check on this forum post if it helps

How to properly calculate ContractCallTx fee?

I am not sure if it is exposed in the SDK. Note that the miminum fee depends on a couple of different components, one of which is the size of the transaction itself. This means that if you compute the tx minimum fee and recreate the transaction with that new fee - the bytesize of the new transaction could as well be bigger than the previous one. This would mean something counterintuivite: adding more fee could require adding a bit more fee I think this is something @milenradkov.chain h…

Also this one is somehow related

Calculate gas without using dry-run

Possibly you shouldn’t run them every time. The gas being consumed is being subtracted from the provided gas and the test is being returned to the caller. If you add too much gas, the unused one is getting back to you so this shouldn’t be a problem. Then you only need a rough estimate to provide a reasonable gas limit and that’s it Regarding the gas price - this should be per user to decide - the higher gas price will likely result in the transaction being included faster. If no…
