Lido Finance is winding down its operations on the Polygon network due to low user adoption and a strategic shift back to Ethereum, following a community vote where 99% supported the decision. Staking requests on Polygon ceased on December 16, 2024, with withdrawals available until June 16, 2025, while all rewards have been discontinued. This move reflects broader challenges in the DeFi landscape, particularly the migration towards zkEVM solutions.
