At this time we do not plan to support Bitcoin Gold in Jaxx. We are, however, monitoring the situation closely and with great interest.
As of the writing of this post, October 23, Bitcoin Gold does not have fully formed consensus code or a functional codebase, they have not Implemented replay protection, or have adequate code for testing and auditing, or have publicly known code developers. The Bitcoin Gold codebase does however contain a private premine of 8,000 blocks (100,000 BTG) owned and controlled by those anonymous developers.
Of the concerns with BTG by far the one weighing most on our minds is the lack of replay protection. If Bitcoin Gold does not implement strong two-way replay protection your BTG and BTC might be vulnerable to attack if you send BTG transactions. Do recall our previous post on replay protection, here.
We do not currently have plans to support BTG in Jaxx. However, we will continue to monitor the BTG situation and will notify you of decisions we make here on our blog.
Our priorities are, as always, the security of our users’ funds. You will always have control of your assets and private keys through your 12-word backup phrase.
If the BTG development team see this message we’d like to encourage them to reach out to us on [email protected]

On the Topic of Segwit2x VS Bitcoin Core and Replay Protection
Regardless of the outcome of the coming hard fork in November, your funds will be safe on both chains. Some websites claiming to be official have said that Jaxx will not be compatible with either of the chains. This is incorrect.
November’s Segwit2x hard fork is coming closer and the team here at Jaxx are monitoring developments in the conversations within both the Segwit2x and Bitcoin Core communities closely. There have been major developments in recent days that leave the question of how best to manage replay protection up in the air. Our intent is to implement a solution that ensures our users funds continue to be maximally secure. The specifics of how we accomplish this depend on the outcome of the fork.
Each user should understand: after the hard fork every transaction in both chains will be affected by replay attacks if neither chain implements replay protection. This is a concern for every individual in the entire community regardless of which wallet solution we each use.
There is good news for each of us. Regardless of the outcome of the Bitcoin Core VS Segwit2x fork there are steps Jaxx users may take to minimize the risk they’re exposed to:
After the hard fork – in both chains – the first transaction you do should be to transfer all your holdings from your current wallet to a brand new wallet under your control.
Do see this link from Diogo Monica for more detail.
Jaxx mission is to continue to provide a secure and chain-agnostic platform that ensures you have complete control of your assets. Jaxx users are in complete control of their private keys through their masterseed; Jaxx never stores your keys server-side and never has access to your funds.
