Aave's Equities Hub on Base allows users to post seven Coinbase stock tokens as collateral for USDC loans, with a borrowing cap of $21 million. The market remains open for lending and liquidations over the weekend, but its equity-linked price feeds continue using levels near Friday's close until updates resume on Sunday evening. A sharp drop in the underlying shares during that window could produce a one-off adjustment when the feed restarts, leaving USDC suppliers in the pool exposed to potential bad debt.
Aave Labs said on September 25 that the V4 Equities Hub had resumed operations. The $21 million figure is the borrowing cap for the Mag-7 lending silo, not evidence that an equivalent amount has already been lent. The silo also has a $32 million USDC supply cap. Those limits control borrowing and deposits separately and cannot be used to infer the market's current utilization.
Price feeds pause while liquidations remain active
The eligible collateral tokens are AAPLc, AMZNc, GOOGLc, METAc, MSFTc, NVDAc and TSLAc. The dedicated lending silo supports USDC borrowing only. LlamaRisk, the risk adviser that proposed the market's initial parameters, said USDC suppliers must opt into this stock-token exposure; funds do not flow automatically from Aave's other markets.
Chainlink's equity-linked feeds combine the underlying share price with the multiplier set by the Coinbase issuer. Under the operating schedule defined by LlamaRisk, the feeds update from 8 p.m. Eastern Time on Sunday through 8 p.m. on Friday. During weekends and U.S. stock-market holidays, prices remain at the last recorded reading. Aave's market, however, continues to accept deposits, loans and liquidations, while the stock tokens can still trade on-chain.
That creates a timing gap between market prices and the health of collateralized positions. If collateral values move while the feed is paused, the protocol does not immediately reflect the change. USDC interest continues to accrue and can push positions closer to their liquidation thresholds even while the price reading is unchanged. If a stock token falls, a position may not appear liquidatable until the feed resumes on Sunday evening. Liquidators who receive the collateral may also need to hold the exposure until liquidity improves during Monday's stock-market session.
Collateral factors leave a limited liquidation buffer
The collateral factors for the seven tokens range from 65% to 79%. LlamaRisk said that in Aave V4, the factor determines both the borrowing capacity assigned to each token and its liquidation threshold. The resulting discount is intended to absorb price declines that may occur after a position becomes eligible for liquidation but before the liquidator can dispose of the collateral. It does not guarantee coverage against every future market move.
LlamaRisk's stress tests used historical price changes during periods when the relevant stock markets were closed. They also assumed a possible 0.5% difference between the oracle price and the market price. The model calculated debt growth through the longest market closure using the top end of the USDC borrowing-rate curve, an annualized 24%, and assumed that liquidation would be completed no later than five minutes after the next regular stock-market open. Each token's collateral factor was set using its historical maximum drawdown and estimates of the statistical tail of returns.
LlamaRisk noted that historical samples cannot capture extreme moves that have never occurred within the sample. The highest liquidation bonus in the market is 5.5%, intended to compensate liquidators for the cost of selling, redeeming or hedging the tokens after repaying the USDC debt. Whether that incentive covers actual disposal costs depends on prices and executable liquidity at the time of liquidation.
Redemption eligibility could constrain exits
Receiving a liquidated B20 token does not necessarily give the holder an immediate right to redeem it with the issuer. LlamaRisk's technical assessment said secondary-market buyers initially receive positions that have not completed the vesting process and must pass through an issuer-controlled vesting procedure before redemption. A liquidator without the required eligibility can sell the tokens on Base, find a counterparty that can redeem them, or hedge the exposure while arranging an exit. The perpetual-futures hedge mentioned in the risk assessment is a modeling option, not a guarantee that every liquidation will have sufficient trading capacity.
Using data from September 17, before the market went live, LlamaRisk estimated that sell-side depth on Base for each token was roughly $270,000 to $1.08 million for a price impact of up to 2%. That was a liquidity snapshot for a specific date and does not establish the amount that could actually be traded on September 27. Larger disposals may require liquidators to split orders or transfer the tokens to a party that can participate in redemption.
If liquidation proceeds are sufficient to repay the USDC debt, the lending pool does not incur a shortfall. Bad debt could remain in the Equities Hub if the post-reopening price gap exceeds the model's buffer, or if the collateral cannot be sold or hedged at the expected price and speed. Any resulting shortfall would be borne by USDC suppliers who actively participate in the silo. The existing risk documentation describes potential scenarios rather than recorded losses; the realized exposure will depend on outstanding loans, collateral positions and available market liquidity when the price feeds resume.
Activation followed Snapshot approval
Aave Labs previously said the activation was based on a binding Snapshot vote. The Protocol Security Council directly removed the pause on the deployed market, meaning no separate AIP or Aave Governance V3 vote was required for this activation. Aave Labs later confirmed that the security council had carried out the action. A separate risk-management configuration was still described as requiring the AIP process.
