Hello everyone. Can someone explain to me what HD wallets mean in plain English... When can I use it in Blockchain development?

I would say it is an easy way to sign transactions
const web3 = new Web3(new HDWalletProvider(privateKey, RPC_URL)),
see you instantiate your provider using HD wallets and in this way your transactions get automatically signed.

For signing you need your privateKey, and HDWallet makes it comfortable for you to sign them, you only need to declare your privateKey once, instead of signing each transaction manually

This is more of a javascript related question:

TypeError: Cannot read property 'to' of undefined

How can I filter my catch block for TypeError errors?
I basically want to filter for errors which are not TypeErrors

this code wont do it, any suggestions ?

Hirearchial deterministic wallet

Simply deriving private keys from mnemonics

Its hirearchial, means current private key generated depends on some nonce

Also previous address
