The bug lone affects the Polygon implementation, and V3 is unaffected
A bug successful an older mentation of crypto lending protocol Aave is blocking users from interacting with Wrapped Ether (WETH), Tether (USDT), Wrapped Bitcoin (WBTC) oregon Wrapped Matic (WMATIC) pools connected Aave V2 Polygon, preventing assets from being withdrawn from them, according to a May 19 connection that attempts to fix the bug done a patch. The connection says that users are presently incapable to "supply much of those assets, borrow, repay, oregon withdraw."
Although withdrawals are presently impossible, the squad stated that funds are "perfectly safe," arsenic the bug tin beryllium fixed aft a governance vote.

The basal origin is the caller ReserveInterestRateStrategy is lone compatible with Ethereum, not compatible with Polygon. https://t.co/kg5696QNPo pic.twitter.com/Ze3zSBS8Ck
The bug lone affects Aave V2 connected Polygon. AaveV3, which is the astir caller version, remains unaffected, arsenic does V2 deployments to Ethereum oregon Avalanche.
The breached codification arose due to the fact that of a May 16 involvement complaint curve spot applied to each deployments of V2. The Polygon implementation of V2 uses a somewhat antithetic database of relation definitions (called an “interface”) for its complaint strategy contracts erstwhile compared with the Ethereum and Avalanche implementations. But the involvement complaint curve changes did not instrumentality into relationship this difference, causing the bug to make lone successful the Polygon deployment.
The caller connection asks Aave’s governing body, Aave DAO, to o.k. codification changes to lone the Polygon mentation to hole the patch. Voting is scheduled to statesman connected May 20, and volition proceed until May 23, the connection stated.
