Aave runs the largest lending book in crypto — and it just rebuilt the machine underneath it.
BUSINESS
Aave is a decentralized lending protocol where users supply crypto assets to earn interest and borrow against collateral.
The interest borrowers pay flows to suppliers, while a reserve cut of borrow fees accrues to the Aave DAO.
GHO is Aave's native overcollateralized stablecoin, minted through governance-approved facilitators; the Aave V3 Ethereum pool was the first facilitator, and a FlashMint module keeps the peg tight through arbitrage.
$AAVE holders govern the protocol: risk parameters, new markets, and treasury spending are decided by on-chain votes.
Users can also stake protocol assets in Umbrella, Aave's automated safety system, earning rewards while backstopping bad debt.
Governance has debated a fee switch that would route roughly $60 million in annual protocol revenue to $AAVE holders.
TECHNOLOGY
Aave V4 deployed on Ethereum on March 30, 2026, replacing pooled markets with a hub-and-spoke design: one central liquidity hub feeds borrowing spokes that each set their own collateral rules.
The old supply and borrow caps become add caps, limiting what a spoke may deposit into the hub, and draw caps, limiting what it may borrow, so risk stays isolated per market.
V4 deposits crossed $1.16 billion by mid-September, up from under $340 million at the start of August, with active loans near $300 million.
A single cash market on Optimism, holding more than $300 million, is the largest spoke driving that growth.
V4 expanded to Avalanche on July 15, 2026 with up to $15 million in milestone incentives, and the first spoke there is planned for tokenized real-world assets.
V3 still holds roughly $31 billion in deposits, so both engines run in parallel and earn fees while users migrate at their own pace.
Umbrella automates bad-debt coverage: if a deficit crosses a preset threshold in one asset, staked aTokens or GHO are burned to cover it with no governance vote, and stakers face a 20-day withdrawal lock.
SECTOR
DeFi lending holds about $50.4 billion in total value locked as of September 2026, and Aave accounts for roughly 36% of it.
Outstanding on-chain loans grew from $20.1 billion in June to $26.1 billion in August 2026, so borrowing demand is climbing, not flat.
Tokenized credit is moving on-chain: Galaxy closed a $75 million tokenized collateralized loan obligation on Avalanche in January 2026.
Aave is positioning for that trend with a dedicated V4 spoke for real-world assets.
COMPETITION
$MORPHO runs isolated markets with curator-managed vaults and has grown to roughly $10 billion in deposits, charging no protocol fees; Coinbase routes more than $1.5 billion of retail collateral through its infrastructure.
A 2018-era pooled-lending pioneer still operates with a simple pooled design, though its share has shrunk to a few billion dollars.
Aave's edge is scale and a battle-tested risk engine; the open question is whether curator-driven vaults keep pulling share from its pooled model.
TOKENOMICS
CoinGecko reports a market cap near $2.70 billion and a fully diluted valuation near $2.79 billion.
About 15.44 million of a 16 million maximum supply circulate, so roughly 96.5% of the supply is unlocked.
No unlock schedule could be verified from a cited source this run; the circulating-versus-max fact stands alone.
