Lisk is a finance platform for businesses that brings accounts, payments, and approvals into one workspace, with fiat and stablecoins managed side by side. Founded in 2016, Lisk previously built blockchain infrastructure, first as a proof-of-stake layer 1 and later as an Ethereum layer 2 on the OP Stack, and backed early-stage startups through grants and accelerator programs. The company shifted its focus to the finance platform in August 2026 and shut down the Lisk Chain on November 2, 2026. LSK continues as the platform's loyalty token on Ethereum.
