Fees#
import { Fee } from '@terra-money/terra.js';
const msgs = [ new MsgSend( ... ), new MsgSwap( ... ), ]; // messages
const fee = new Fee(50000, { uluna: 4500000 });
const tx = await wallet.createAndSignTx({ msgs, fee });
Automatic fee estimation#
If you don’t specify a fee when you create your transaction, it will automatically be estimated by simulating it within the node.
const tx = await wallet.createAndSignTx({ msgs });
You can define the fee estimation parameters when you create your LCDClient instance. The defaults are:
const terra = new LCDClient({
URL: 'https://lcd.terra.dev',
chainID: 'columbus-5',
gasPrices: { uluna: 0.015 },
gasAdjustment: 1.4
});
You can override these settings by passing the fee estimation parameters in wallet.createTx or wallet.createAndSignTx:
const tx = await wallet.createAndSignTx({
msgs,
gasPrices: { ukrw: 0.01 },
gasAdjustment: 1.9
});
