Aave Labs proposed flash-loan fee exemptions for new CoW adapters on October 28.

What happened

Aave Labs proposed registering new swap adapter factories as fee-exempt flash borrowers on October 28, 2026.

What changed

Aave Labs requested exemptions for factories supporting collateral swaps, debt swaps, repayment with collateral and leverage.

What did not change

Aave Labs stated that governance would next need to vote. The proposal establishes no executed exemption.

Confirmed

• Aave Labs named AaveV3AdapterV3Factory and AaveV3AdapterV4Factory as the factory types.
• Aave Labs proposed using ACLManager.addFlashBorrower for the listed factory addresses.
• Aave Labs included Ethereum Core, Ethereum Prime, Base, Arbitrum, Gnosis, Avalanche, BNB Chain, Polygon, Linea and Plasma.

Still open

• Aave governance has yet to establish approval and execution through the cited proposal.

What it means for an advisor

• Ketju should verify executed exemptions before changing the Aave memo’s explanation of swap, repayment and leverage costs.
• The proposed exemptions provide no basis to expand Ketju’s approval beyond Ethereum GHO and sGHO.
