    We say it is but you shouldn't just trust us. We have published and open sourced Bitcoin Afterburner and encourage the community to review the code.

    It goes without saying that neither the wallet mnemonic or the private keys are ever communicated with any external servers. Afterburner runs completely client side on your device and uses our bitcoin nodes to broadcast your transaction publicly to the bitcoin network.

    The transaction creation and signing code has been in use and tested by thousands of users since 2015 in our other project Samourai Bitcoin Wallet. We are very confident in our products and we want to keep our good reputation in the community.
