The claim window is closing
Compound V2 users on Ethereum have until 5 p.m. ET on Nov. 10, 2026, to claim legacy COMP rewards. The Compound Foundation said unclaimed tokens will return to the Compound treasury after that cutoff. The deadline covers previously earned V2 rewards. It does not affect lending deposits.
Users need to connect the same wallet they used on V2 to claim their allocation. The migration instructions point them to Compound’s rewards page or the Merkl rewards platform. They do not need to move a lending or borrowing position. That point matters because some users may confuse a rewards claim with a position migration. They are separate steps.
Why the deadline exists
The cutoff closes a claim window that opened when Compound moved legacy rewards distribution to Merkl. Before that change, users could claim accrued rewards at any time through Compound’s interface or its reward contracts. Under the new terms, the Treasury Management Committee, acting as distributor administrator, returns unclaimed COMP to the Treasury Timelock after the window closes. Users do not need to send tokens back themselves.
The V2 campaign opened in September with about 40,419 COMP in allocations across 18 Ethereum markets, according to the Foundation’s published migration records. That number reflects rewards remaining at the migration snapshot after earlier claims through legacy contracts. It is not the amount still unclaimed today. The distinction is easy to miss, and it may explain why some figures around the deadline look larger than the actual pool left to claim.
Separate deadline for V3 rewards
DeFi Saver said on Nov. 10 that V2 rewards were also claimable through its interface. The service stressed that the deadline concerns V2, which launched in 2019 and has largely been superseded by V3 since 2022.
Legacy V3 rewards have a different cutoff. According to the migration records, those rewards on Ethereum, Arbitrum, Optimism, Base, Polygon and Unichain can be claimed until March 10, 2027, at 5 p.m. ET. V2 users who have not checked their wallet in a while should probably do so before the November deadline.
