I found your article on Medium and it's a great read. Thank you for writing with such clarity. It's a great article to follow. I just had a few questions about your code.

1. You used web3 in multiple places and I am not sure how you imported it as I didn't see a require statement and how you instantiated web3 as I was under the impression that it requires a provider url (such as infura) and metamask mnemonic
   I am leaving the code here in case you want to check.

//To get user ERC721 token balance - counter of how many assets a user owns
  async getUserBalance() {
    const balance = await this.state.ledger.getBalance(web3.eth.accounts[0]);
    return balance;
  }

2. Does uriBase.json contain the metadata for the assets? If so, does it mean I should add all my assets in uriBase.json and read from there? (I am confused about this.)

3. Also, what did you think about 0xcert? Would you recommend it for someone building their first dApp for a client? Thanks.
