AAVE v4 deposits surpass $1B, doubling in a month

Aave’s fourth-generation protocol just crossed the $1 billion deposit mark, roughly doubling its total in a single month. The milestone, reached around September 16-17, puts V4 on a trajectory that even the protocol’s most optimistic backers probably didn’t pencil in this early.

To put the speed in perspective: Aave V4 deposits sat below $340 million at the start of August. By early September, that figure had climbed to roughly $577 million. Now it’s hovering around $1.16 billion, with active loans running between $300 million and $310 million.

What’s driving the surge

A significant chunk of V4’s growth traces back to one particular corner of the ecosystem: the Ether.fi Cash market on Optimism. That single market crossed $300 million in deposits, making it a heavyweight contributor to V4’s overall numbers.

The architectural innovation behind V4 is what Aave calls a “hub-and-spoke” liquidity model. Rather than pooling all assets into one monolithic lending market the way earlier versions did, V4 lets developers spin up specialized markets (the spokes) that connect back to a central liquidity hub.

Aave V4 launched on Ethereum mainnet in March 2026, and the ramp-up since then has followed a staircase pattern. August alone saw active loans jump from roughly $115 million to over $200 million, setting the stage for September’s deposit explosion.

V4 versus V3: still a different weight class

Before anyone crowns V4 as the new king, some context. Aave V3, the workhorse version that’s been accumulating deposits for years, holds approximately $31 billion. That means V4, at $1.16 billion, accounts for less than 4% of Aave’s total deposit base.

Market response and the metrics question

The AAVE token has reflected the protocol’s momentum, testing resistance levels near $145 as V4’s adoption numbers climbed.

There is, however, a wrinkle worth noting. Discrepancies exist between the deposit figures Aave reports through its own interface and the numbers tracked by external aggregators like DeFiLlama. The $300 million in active loans against $1.16 billion in deposits implies a utilization rate of roughly 26%, which sits in a healthy range for lending protocols, neither dangerously high nor suspiciously low.
