A bug in an older version of crypto lending protocol Aave is blocking users from interacting with Wrapped Ether (WETH), Tether (USDT), Wrapped Bitcoin (WBTC) or Wrapped Matic (WMATIC) pools on Aave v2 Polygon, preventing assets from being withdrawn from them, according to a May 19 proposal that attempts to fix the bug through a patch. The proposal says that users are currently unable to “supply more of those assets, borrow, repay, or withdraw.“
