Is there an ABI for wallet addresses?

Question

If I am using the Web3 library, and I want to fetch a list of all tokens associated with my user account, would I be completely wrong in thinking that I need to use:

const myAccount = new web3.eth.Contract(..

Feeding in my public key and an ABI representing some 'createUserOnEthereum' contract?

Basically, my question here should probably be, when I create a wallet (and then make my first transaction), does the EVM create an 'instance' of my wallet on Ethereum using some kind of 'createUserBasedOnTheirGenereatedPublicKey()' function?

As far as I know, no wallet would ever be recognised if no transaction was ever made (and the EVM would never see my private keys anyway right?)

Thanks!

You are right. When a new wallet is created nodes do not know about it until it is involved in a transaction. Once it does, the nodes will save the new account in their local world state trie. There is no smart contract involved for address registration (the accounts are not stored on-chain), it is managed locally by the nodes.

Yes. Just the signed transaction is needed.

There is no simple, straightforward way to know all the tokens held by any account. You could however know about the different ERC20s it has using a blockchain explorer like Etherscan.
