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 });

You can define the fee estimation parameters when you create your LCDClient instance. The defaults are:

_6

const terra = new LCDClient({

_6

URL: "https://phoenix-lcd.terra.dev",

_6

chainID: "phoenix-1",

_6

gasPrices: { uluna: 0.015 },

_6

gasAdjustment: 1.4,

_6

});

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

_5

const tx = await wallet.createAndSignTx({

_5

msgs,

_5

gasPrices: { ukrw: 0.01 },

_5

gasAdjustment: 1.9,

_5

});
