[Ethereum] Total metamask balance

balanceshd-walletsmetamask

I am curious how to get the total current balance of my metamask wallet with as many "accounts" inside it as it bears in the moment?

As I can understand metamask is the HD wallet and all my addresses in it are derived from my seed phrase and xpub/private key.

So is it possible to find a service or (preferably) to write a script to calculate total balance of my metamask wallet using my xpub or another root info? Please show me the right direction. Thank you.

You can get the balance of a single account via:

web3.eth.getBalance(address);

By default you will get all accounts of metamask. (this code uses await and therefore has to be placed within an async function)

const accounts = await web3.eth.getAccounts();

What you get is an array with all the accounts. Now it is up to you to loop through them and sum up the balance.

Check your address at https://rinkeby.etherscan.io/address/ to see if you actually have a balance. If not, it's possible that you did get it in a block, and you saw your balance in that block, but the block was then orphaned. If this balance is different than what shows in Metamask, then you'll have to go to Metamask Support

Edit: It sounds like the issue is because OP used the mnemonic that Truffle gives you, which is the same for everyone (since it's for running tests, which should be deterministic). WARNING: Do not use the mnemonic from truffle! Just look at it, all the words are sweets, so it's bad for you...

Apparently, this is not the same inside the anonymous callback function you're passing to getBalance. Try replacing it with a fat arrow function, that binds the outer this value to the inner scope.

this.web3.eth.getBalance(this.account, (err, balance) => {
  this.balance = this.web3.fromWei(balance, "ether") + " ETH"
});
