What Is the Transferfrom() Function and How Does It Relate to Approve() ?

The transferFrom() function is the counterpart to approve(). After a user has called approve() to grant an allowance, the spender (the dApp's smart contract) can then call transferFrom() on the token contract.

This function instructs the token contract to move a specified number of tokens from the user's address to a recipient's address. The token contract first checks if the spender has a sufficient allowance from the user before executing the transfer.
