The Ethereum ERC-20 standard explained in a few sentences:
Token balances aren’t stored in your wallet; they’re recorded in the token contract’s own ledger. Your wallet simply reads those records.
The approve and transferFrom mechanisms allow a contract to transfer tokens on your behalf, up to the authorized amount. This is also the source of authorization risks.
When adding a custom token, verify the contract address through official channels or a block explorer. Don’t use an address provided by a stranger.
