What Happens If You Send Crypto to the Wrong Address?

Sending crypto to the wrong address is one of the costliest mistakes in digital finance. Unlike a bank transfer or card payment, most crypto transactions cannot be cancelled once they are confirmed. Bitcoin’s official documentation says confirmed transactions are irreversible. Only the person who controls the receiving address can send the money back. Ethereum follows the same rule, and no central authority can undo a transfer. The phrase “wrong address” covers many different situations, though. Some end in permanent loss, and others can be fixed in minutes.
