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.

_1

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:

_11

const lcd = new LCDClient({

_11

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

_11

'chainID': 'pisco-1',

_11

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

_11

'gasAdjustment': 1.75,

_11

'gasPrices': {

_11

'uluna': 0.015

_11

},

_11

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

_11

}

_11

});

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

_6

const tx = await wallet.createAndSignTx({

_6

msgs,

_6

gasPrices: { uluna: 0.01 },

_6

gasAdjustment: 1.9,

_6

chainID: 'pisco-1',

_6

});
