Statement on Bitcoin Gold fork
Bitcoin Gold is a proposed fork of Bitcoin, sharing its history up until the block height 491407 (around October 24, 6am UTC). As Bitcoin Gold has a subsequent pre-mine period, we do not yet know when the coin will launch.
If you have held bitcoins on TREZOR before this block, you will have the same bitcoin gold balance as your bitcoin balance. However, for the reasons stated below, TREZOR Wallet will not support bitcoin gold yet.
Will TREZOR support bitcoin gold?
Yes, TREZOR (the device) supports bitcoin gold. As previously mentioned, at the moment of the fork, if you have bitcoins on your TREZOR, you will also receive bitcoin gold on your TREZOR (both new and legacy accounts are supported in bitcoin gold). If you simply wish to hold BTC and BTG, there is no further action required from you.
Will TREZOR Wallet support bitcoin gold?
Bitcoin Gold’s codebase is, at the moment of the writing, incomplete. Most importantly, it lacks replay protection. For this reason, TREZOR Wallet will not support bitcoin gold yet, as it would endanger your bitcoins.
