Aave proposes removing one toll from its swap routes.

Aave Labs' 28 October proposal would whitelist new CoW swap-adapter factories as approved flash borrowers on specified Aave V3 markets. That would remove the flash-loan premium for those approved routes. The forum post describes a proposed governance change, not a completed rollout.

The adapters support collateral swaps, debt swaps, repayment using collateral and leverage. Some routes borrow liquidity briefly to complete the operation; the proposal says the associated premium currently worsens execution for those users.

The requested exemption applies to named factory contracts and markets, including Ethereum Core, Base and Arbitrum. Its next step is an AIP vote if the community supports proceeding. A proposal title mentioning V3/V4 should not be mistaken for a blanket fee waiver: the specifications identify particular factories and Aave V3 deployments.

Removing that premium would address one component of a transaction's cost. It would not establish that all swaps are free, eliminate borrowing costs or make leveraged positions safe. The useful test after any approved execution would be whether the covered routes actually deliver better pricing.
