An upcoming Lisk network hard fork will remove support for hardware wallets including the Trezor Model T and Model One.
If you currently store Lisk on your Trezor wallet, you must move your coins to a wallet compatible with the hard fork upgrade by August 21 2021. The Lisk Desktop wallet should be compatible, according to Lisk’s public communications.
The short notice given regarding this issue is due to the fact that Lisk did not provide any notice of the incompatibility ahead of time nor did they reach out to discuss a solution or workaround. Given the nature of this hard fork, the currently implemented code will be made redundant and the codebase will be removed from Trezor products.
There are no clear paths to reinstating support at this time as resolving the compatibility issues would require extensive development efforts on both sides, which would not be productive given the lack of cooperation in this case.
We hope to hear from the Lisk development team in the coming days, and will follow up should there be any news in future. In the meantime, please immediately withdraw all Lisk tokens from your hardware wallet to a compatible wallet for safekeeping.
