Trezor is still requiring an update. The code has been done, but Digiexplorer has not been. I have been in touch with the developers channel and they are aware of it. Once this is done, we can get an official announcement from Trezor that we are integrated.
Hopefully Trezor are supporting DGB, if not now soon...... Ledger are now for sure.
Everything is done on DGB's side for Trezor to support it. Trezor requested DGB do some technical things which have been completed. I contacted Satoshi Lab's and asked them about Digibyte support and when it will be ready. They said it is a project on their agenda but have other higher priority projects they need to complete first. I suspect is is mostly Trezor model T which has been delayed a month to February. Hopefully when the Trezor devs have more time on their hands they can complete the Digibyte support project. It is coming, they just won't say when.
