I have some truble on migrate smart contract using infura on the mainnet of eth.

The truffle-config.js is as below:

const HDWalletProvider = require('truffle-hdwallet-provider');

module.exports = {
  networks: {
    mainnet: {
      provider: new PrivateKeyProvider("my private key", "https://mainnet.infura.io/v3/my project id"),
      network_id: 1,       // Ropsten's id
    }
  }

I use truffle migrate --network mainnet and get the message:

Riley,

I see your transactions as having gone through on etherscan:

https://etherscan.io/address/0xeb510b7a46064cc5b8726c77af9f6dfceae02000

Did you change anything on your end or simply try the migration again? If you could please let us know what you tried to resolve the issue it’ll help us further debug how the migration might’ve failed the first time.

Thanks!
Ryan

Yes.

Yesterday I find a blog Deploy Your Smart Contract Directly from Truffle with Infura and find he set the gasPrice. So I think it maight the default gas price is not good enough. I change the truffle-config.js as below:

const HDWalletProvider = require('truffle-hdwallet-provider');

module.exports = {
  networks: {
    mainnet: {
      provider: new PrivateKeyProvider("my private key", "https://mainnet.infura.io/v3/my project id"),
      network_id: 1,       // Ropsten's id
      gas: 3000000,
      gasPrice: 10000000000
    }
  }
}

Then everything works fine.

now suppose I am calculating my costing for total gas* gas price is around 0.2. Is there any calculation that what amount I need to keep in my wallet balance?

@Rakib_Hossain you should have enough ETH in the wallet balance to be able to pay for the migration.
Have you encountered any errors so far?

yes. I got this message
