Lisk is shutting down its original Lisk Chain on October 31, 2026, requiring holders with LSK tokens on that chain or staked there to bridge their tokens to Ethereum by October 21, 2026. This deadline accounts for a three-day unstaking period plus a mandatory seven-day challenge period for bridging, meaning action must start at least ten days before shutdown. Tokens already on Ethereum or held by exchanges require no action. Missing the deadline means tokens left on the Lisk Chain will become permanently inaccessible. The token itself continues on Ethereum with no swap or change, and Lisk shifts focus to payment and treasury software with LSK as a loyalty point. Users must carefully follow the multi-step bridge process and record transactions for bookkeeping and tax purposes.
