Calculating Fees
Make sure to create a fee object in addition to your message.
import { coins } from '@cosmjs/amino';
const fee = {
amount: coins(0, 'uosmo'),
gas: '250000'
}if you are broadcasting multiple messages in a batch, you should simulate your tx and estimate the fee
import { Dec, IntPretty } from '@keplr-wallet/unit';
const gasEstimated = await stargateClient.simulate(address, msgs, memo);
const fee = {
amount: coins(0, 'uosmo'),
gas: new IntPretty(new Dec(gasEstimated).mul(new Dec(1.3)))
.maxDecimals(0)
.locale(false)
.toString()
};
