Bug in Aave v2 Polygon Causes Some Assets to Become Stuck in Contracts


Aave, a decentralized finance (DeFi) lending platform, has recently encountered a bug in its v2 Polygon deployment. The bug has caused some assets to become stuck in contracts, preventing users from accessing their funds.

The issue was first reported on June 14, 2021, and Aave has since acknowledged the problem and is working on a fix. However, the bug has caused concern among users who are unable to withdraw their assets.

What is Aave v2 Polygon?

Aave v2 Polygon is a version of the Aave protocol that is deployed on the Polygon network. Polygon is a layer 2 scaling solution for Ethereum that aims to improve the network’s scalability and reduce transaction fees.

Aave v2 Polygon allows users to lend and borrow assets on the Polygon network, with lower fees and faster transaction times than on the Ethereum network.

The Bug and Its Impact

The bug in Aave v2 Polygon causes some assets to become stuck in contracts, preventing users from withdrawing them. The affected assets include USDC, USDT, DAI, and WBTC.

The bug is related to the way Aave v2 Polygon handles flash loans, which are a type of loan that is borrowed and repaid within the same transaction. The bug causes flash loans to fail, which in turn causes assets to become stuck in contracts.

The impact of the bug is significant, as users are unable to access their funds. Aave has advised affected users to contact their support team for assistance.

Aave has also advised users to avoid using flash loans on Aave v2 Polygon until the issue is resolved. They have assured users that their funds are safe and that they will be able to withdraw them once the bug is fixed.
