There are two scenarios could occur with the Bitcoin Cash ABC (BCHA) and Bitcoin Cash Node (BCHN) contentious hard fork, they are:

Scenario A: The fork results in two competing chains. Crypto APIs will support both chains.
Scenario B: No new coin is created. Crypto APIs will then resume supporting BCH.

As per the latest data, +90% of BCH blocks have signaled support for BCHN over the last days. If this signaling status continues through the hard fork, Crypto APIs will treat the BCHN chain as the future BCH chain which means your requests to /bch/ will be treated as /bchn/. In this case, we will add support for BCHA as well, to access it your calls should be /bcha/ instead of /bch/.

Should the signaling support change prior to the hard fork, Crypto APIs reserves the right to update the treatment of the chain split in a further announcement.
