Aave V4 collateral asset swap, live on 3 networks

Aave has added borrow-asset swapping to its V4 markets on Ethereum, Base, and Avalanche, letting users switch the asset they owe without closing their loan position. The feature, announced by Aave on X and routed through CoW Swap, collapses the repay-swap-reborrow sequence into a single step. Swaps are restricted to the same spoke as the existing borrow position, and the new asset must be borrowable. The rollout follows the earlier addition of collateral swapping on the same three networks, extending Aave V4's position-management tooling across its main deployments. Next to watch is whether the feature draws more refinancing activity and volume through CoW Swap on those markets.
