Fees

import { Fee } from '@terra-money/feather.js';

const msgs = [ new MsgSend( ... ), new MsgExecuteContract( ... ), ]; // messages

const fee = new Fee(50000, { uluna: 4500000 });

const tx = await wallet.createAndSignTx({ msgs, fee, chainID: 'pisco-1' });

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, chainID: 'pisco-1' });

You can define the fee estimation parameters when you create your LCDClient instance. The recommended values are as follows:

const lcd = new LCDClient({

'pisco-1':' { // key must be the chainID

'chainID': 'pisco-1',

'lcd': 'https://pisco-lcd.terra.dev',

'gasAdjustment': 1.75,

'gasPrices': {

'uluna': 0.015

},

'prefix': 'terra', // bech32 prefix, used by the LCD to understand which is the right chain to query

}

});

You can override these settings by passing the fee estimation parameters in wallet.createTx or wallet.createAndSignTx:

const tx = await wallet.createAndSignTx({

msgs,

gasPrices: { uluna: 0.01 },

gasAdjustment: 1.9,

chainID: 'pisco-1',

});
