Fees

const fee: StdFee = {
    amount: [Coin.fromPartial({denom: "axpla", amount: "28000000000000000"})],
    gas: "100000",
}
const tx = await signer.signAndBroadcast({messages: [msg], fee: fee})
console.log(tx)

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 signer.signAndBroadcast({messages: [msg], fee: fee})

How to calculate accurate Fee #

The following example demonstrates how to automatically estimate transaction fees using the estimateFee method. This approach is more accurate than manually setting fees as it simulates the transaction on the network to determine the exact gas requirements:

const fee: StdFee = await signer.estimateFee({messages: [msg], options: {multiplier: 1.3}})
const tx = await signer.signAndBroadcast({messages: [msg], fee: fee})
