Once initiated, transactions can not be canceled or reversed. If you sent bitcoin to the wrong address and you know the receiving party, you can contact them and see if they are willing to return the bitcoin to you. If you don’t don’t know the receiving party, due to the decentralized nature of bitcoin, there is nothing further that can be done to recover bitcoin that was sent to the wrong address.
Tip: To avoid a situation like this, we recommend double-checking the address before sending a transaction. You can also send a smaller transaction first as a test transaction to confirm you have the correct address.
