What Aave announced
Aave posted on its official X account at 16:19 UTC on Wednesday 11 November 2026 (17:19 in Amsterdam) that Aave V3.8 is now live across 15 Aave V3 markets, following approval by the Aave DAO.
Aave said the release was developed by Aave Labs and adds new layers of protection to Aave V3, in line with industry best practices and Aave DAO security standards. The post does not name the 15 markets.
What changes in V3.8
In its governance proposal on the Aave forum, Aave Labs describes V3.8 as a small, security-focused release. Its main change is a reentrancy guard on Pool operations during external callbacks, built on transient storage (EIP-1153), which protects Pool accounting when one transaction touches the Pool more than once.
Aave Labs also explained how this affects flash loans. A flash loan can still trigger other Pool actions, including a liquidation, inside its callback. What the guard blocks is starting a flash loan from inside a Pool action that is already running. The proposal moved to an onchain Aave vote, proposal 541, on 9 November.
Our take
This is a defensive upgrade, not a new product: nothing changes in how you supply or borrow, and Aave did not announce any new rates or assets with it. If you only use the Aave app, there is nothing to do. If you run a bot or contract that calls the Pool, check that your flow does not open a flash loan from inside another Pool action, since that is the pattern the new guard stops.
