Bitcoin ABC takes security very seriously. We greatly appreciate any and all disclosures of bugs and vulnerabilities that are done in a responsible manner. We will engage responsible disclosures according to this policy and put forth our best effort to fix disclosed vulnerabilities as well as reaching out to numerous node operators to deploy fixes in a timely manner.
This disclosure policy is also intended to conform to this proposed standard with some modifications (see below).
Do not disclose any bug or vulnerability on public forums, message boards, mailing lists, etc. prior to responsibly disclosing to Bitcoin ABC and giving sufficient time for the issue to be fixed and deployed. Do not execute on or exploit any vulnerability. This includes testnet, as both mainnet and testnet exploits are effectively public disclosure. Regtest mode may be used to test bugs locally.
When reporting a bug or vulnerability, please provide the following to firstname.lastname@example.org:
We highly encourage all disclosures to be encrypted to prevent interception and exploitation by third-parties prior to a fix being developed and deployed. Please encrypt using the PGP public key with fingerprint:
It may be obtained via:
gpg --recv-keys 5442AB0B9178E0D1567479B471A3ED7ECF82C6A7
Below are some basic instructions for encrypting your disclosure on Linux if you are unfamiliar with GPG:
sudo apt-get install gpg
For Archlinux based distributions:
pacman -S gnupg
gpg --output mydisclosurefile.asc --encrypt --recipient email@example.com mydisclosurefile
These PGP fingerprints and emails are provided only as backups in case you are unable to contact Bitcoin ABC via the security email above.

Neighboring projects that may be affected by bugs, potential exploits, or other security vulnerabilities that are disclosed to Bitcoin ABC will be passed along information regarding disclosures that we believe could impact them. As per the standard referenced above, we are disclosing these relationships here:
Bitcoin ABC cannot commit to bounty payments ahead of time. However, we will use our best judgement and do intend on rewarding those who provide valuable disclosures (with a strong emphasis on easy to read and reproduce disclosures).
While Bitcoin ABC believes that strong cohesion among neighoring projects and ethical behavior can be standardized to reduce poorly handled disclosure incidents, we also believe that it’s in the best interest of Bitcoin Cash for us to deviate from the standard in the following ways:
Note that any changes to this disclosure should be mirrored in a pull request to the bitcoinabc.org repo.
