What Aave V4 is
Aave V4 rebuilds the protocol around a hub-and-spoke architecture: each network's liquidity concentrates in a single Hub, and Spokes, the user-facing entry points for borrowing, e-mode or new asset classes, draw on that shared liquidity, so features ship as new spokes without fragmenting the pool.
Scope
The Sherlock contest covered the V4 core, 44 files and 3,614 nSLOC across the Hub and Spoke architecture: the liquidity Hub's accounting, the borrowing and e-mode Spokes drawing on it, and the risk and rate configuration between them.
