Compound V2 users on Ethereum have a firm date to remember: 5 p.m. ET on Nov. 10, 2026. That is the last moment to claim previously earned legacy COMP rewards. After that, unclaimed tokens go back to the Compound treasury, according to the Compound Foundation.
The deadline is about rewards, not deposits
The cut-off applies to V2 rewards that were already earned. It does not apply to lending or borrowing deposits. Users do not need to move a lending position or a borrowing position. They also do not need to send tokens back themselves. To claim, they must connect the same wallet they used on V2. The Foundation points users to Compound’s rewards page or the Merkl rewards platform.
Why the claim window is closing
The date 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 acts as distributor administrator. After the window closes, it returns unclaimed COMP to the Treasury Timelock.
The V2 campaign opened in September with about 40,419 COMP in allocations across 18 Ethereum markets, according to the Foundation’s migration records. That number is not the same as the amount still unclaimed today. It reflects rewards remaining at the migration snapshot after earlier claims through the old contracts.
V2 and V3 have separate deadlines
DeFi Saver said on Nov. 10 that V2 rewards were also claimable through its interface. The service stressed that the deadline concerns V2. Compound V2 launched in 2019 and has largely been replaced by V3 since 2022.
Legacy V3 rewards have a later deadline. Migration records set March 10, 2027, at 5 p.m. ET for V3 rewards on Ethereum, Arbitrum, Optimism, Base, Polygon and Unichain.
For V2 users, the practical step is simple. Check the wallet, check the rewards page or Merkl, and claim before the November 2026 deadline. I think the main risk is waiting until the final day and running into wallet or site issues. The Foundation has not said it will reopen the window.
