If you have sent Bitcoin Core (BTC) or Bitcoin Cash (BCH) to someone but they say the bitcoins never arrived, please check the receiving address on our block explorer to make sure the funds have been broadcast to the network and sent to the correct address.
You can check all BCH and BTC transactions on the blockchain here: https://explorer.bitcoin.com
If the transaction shows at least one (1) confirmation on the blockchain, then the funds were definitely received at that address.
If necessary, you can send the block explorer URL link to the recipient as "proof-of-payment".
If the recipient states that they did not receive the bitcoins, please ask them to confirm the receiving address. If you have sent to the correct address but the recipient cannot see the bitcoins in their wallet, then it is possible you have mistakenly sent BCH to a BTC address (or vice-versa).
Bitcoin Cash (BCH) and Bitcoin Core (BTC) are both irreversible payment systems so, unfortunately, there is no way to reverse a sent transaction.
However, Bitcoin Cash (BCH) can usually be recovered from a Bitcoin Core (BTC) address (or vice-versa) but this can only be done from the "Receivers" end.
If you have sent the wrong coin, then you will need to ask the receiving party to help recover the funds for you. If they do not know how to recover BCH/BTC, they will need to contact the support team of their wallet provider for instructions.

The recovery instructions on our FAQ page will only work for the Bitcoin.com wallet and only if you are the "receiving" party.
