Aave V4 deposits pass $1.75B after more than doubling since August

Aave V4 has crossed $1.75 billion in deposits, more than doubling in under three months. The protocol's fourth iteration sat near $806 million in late August 2026. By September it passed $1 billion. By October it cleared $1.5 billion. The latest figure marks a record for the version since its March 30, 2026 launch on Ethereum mainnet.

Borrowing has kept pace. Active V4 loans topped $450 million in October. Measured against that month's $1.5 billion in deposits, roughly 30% of supplied capital was out on loan — a utilization level that suggests real demand, not idle capital parked for incentives.

The expansion has been deliberate. After Ethereum mainnet, Aave deployed V4 on Optimism, then Avalanche in July, then Base in October.

Where the money is coming from

Growth is not evenly spread. A few specialized markets carry most of it.

• EtherFi Cash on Optimism contributed hundreds of millions in deposits at peak activity. The crypto spending product gives V4 a steady capital base.
• Circle's Arc blockchain has brought inflows of $USDC and cirBTC. Circle issues $USDC, so Aave now sits next to one of the largest pools of dollar-pegged crypto.
• Base, the newest addition, has seen deposits between $9 million and $25 million-plus. Modest, but the chain only went live for V4 in October.

Aave has also brought in external curators such as Sentora. Curators act as specialist managers who set up and tune markets for particular user groups. That lets V4 serve niche segments without Aave's core team hand-building every market.

Why V4 looks different from V3

V4 runs what Aave calls a hub-and-spoke liquidity model. Central hubs hold the liquidity pools. Individual markets connect as spokes, each with its own rules.

The technical payoff is isolation. Spokes share the hub's liquidity, but their risk settings stay separate. A risky asset in one spoke should not drag down a conservative market in another. The design targets a wide range of assets, including tokenized real-world equities.

V3 is not going anywhere. It still commands around $31 billion in deposits. V4 remains compatible with it, and the two run side by side. Put the numbers together and V4 holds less than 6% of V3's deposit base.

The bigger picture is substantial either way. By October 2026, Aave had processed $1.1 trillion in cumulative borrow volume across all versions. Aave is effectively running two protocols at once: V3 keeps generating revenue and serving existing users, while V4 grows chain by chain.

What does this change for DeFi users?

The practical question: what does this change for anyone lending or borrowing on Aave? The main takeaway is that V4 is attracting capital without Aave forcing a migration. Deposits arrive because specific products — EtherFi Cash, Circle's Arc — find the design useful.

For Aave itself, the concentration is worth tracking. A few integrations account for a large share of V4's growth, which cuts both ways: strong partnerships today, concentration risk tomorrow.

Then there is the tokenized equities ambition. Supporting real-world assets on a lending protocol raises questions about pricing, liquidation and regulation that crypto-native collateral does not. V4's architecture was built with that use case in mind.

The milestones ahead are straightforward. Watch whether V4 keeps compounding deposits at its recent pace, whether the loan-to-deposit ratio holds as new chains come online, and at what point capital starts moving out of V3's $31 billion pool rather than arriving fresh.
