What exactly does ERC-20 specify?
Because the interface is standardized, wallets and exchanges don't need to adapt separately for each type of token, and can support newly issued tokens as well.
Token balances aren't stored in the wallet; they're recorded in the token contract's own ledger, and the wallet simply displays the balance.
The most important thing to keep in mind when managing funds: don't send tokens directly to the token's own contract address. Most of these contracts don't have a withdrawal function, so tokens sent there are often impossible to recover.
