Hi there,

Working to understand how to transfer tokens between two Internet Identity users.

So far ive recevied these outputs.

I took the logged in users Principal ID and used that to interact with the icp ledger. If im getting this right, each II user has a wallet address, where i can send tokens to, yes?

At a high level, you can send ICP to an Account Identifier.

An Account Identifier is a hash that is comprised of a principal ID and a subaccount.

Typically, users want to use their default account which sets the owner to the Principal ID and subaccount set to null as shown in your code:

let accountArgs: {
 owner: userPrincipal;
 subaccount: null;
}

To get the Account Identifier from this, you are using this line of code:

let account_identifier = await icp_ledger_canister.accountIdentifier(accountArgs);

An Internet Identity can return a principal ID.

The [text representation] in Welcome Back, [text representation] should show the principal from the logged-in Internet Identity. I assume that the backend function tied to this returns msg.caller.

It is important to note that the principal returned from the same Internet Identity changes per domain. For example, an Internet Identity logged into xyz.com will return a different principal than from same Internet Identity logged into abc.com. It’s a privacy feature that is included in Internet Identity.

There are more details that I can provide. However, for the sake of not overloading you with too much information at the moment, I suggest you review the Digital Assets Overview and the Internet Identity Specification to learn more.
