Simulate Tx about cosmosjs HOT 3 CLOSED

@atmoner Here's the message structure of SimulateRequest.

const rawMsg = new cosmos.tx.v1beta1.SimulateRequest({
tx: tx,
tx_bytes: txBytes,
});

return new google.protobuf.Any({
type_url: '/cosmos.tx.v1beta1.SimulateRequest',
value: cosmos.tx.v1beta1.SimulateRequest.encode(rawMsg).finish()
});

from cosmosjs.

You need to create SignDoc.

signDoc = (1)txBody + (2)authInfo

Every authInfo will be same when you use only 1 address. You should create SimulateRequest txbody.

You can see msgSend code here.

For creating SimulateRequest txBody, you can search the proto structure at here.

Thank you for your answer @Booyoun-Kim

I tried a lot of things without success!
If you have an example for me, I could better understand how proto works and help you with the documentation.

But I need an example please
