Aave's Base market has accepted seven Coinbase stock tokens as collateral for USDC loans since Sept. 25, capped at a $21 million USDC draw. The tokens' price feeds freeze from Friday evening to Sunday evening even as borrowing and liquidation stay open, leaving opt-in USDC suppliers exposed if a reopening price gap outpaces the buffers built into the market.
Aave's V4 Equities Hub on Base went live after a temporary halt was lifted, and Aave Labs said on Sept. 25 the market was operational. The Mag-7 lending spoke lets seven Coinbase stock tokens — AAPLc, AMZNc, GOOGLc, METAc, MSFTc, NVDAc and TSLAc — serve as collateral for USDC loans, with USDC the only asset borrowers can draw. The $21 million cap limits borrowing rather than reporting loans already made.
A market open while its equity feed is closed
The Chainlink equity-linked feeds that price this collateral combine each share's value with a Coinbase issuer multiplier, and LlamaRisk specifies an operating window from Sunday 8 p.m. to Friday 8 p.m. Eastern time. From Friday evening to Sunday evening, and on US market holidays, the feeds hold their last value instead of publishing a new one, even though the Aave market itself stays open for deposits, borrowing and liquidation.
As a result, a position's price-based health reading cannot reflect fresh information during that closure, and interest on a USDC loan can still push it toward the liquidation threshold while the feed is frozen. A position made unsafe by a falling stock-linked price may only become liquidatable when the feed resumes Sunday evening and absorbs that move in one update, leaving a liquidator to carry the seized exposure until deeper stock-market hours on Monday.
The exit route determines who absorbs a gap
Collateral factors on the seven tokens range from 65% to 79%, and LlamaRisk's stress method assumes liquidation completes no later than five minutes after the next regular stock-market open. But redemption is not automatic: LlamaRisk's technical assessment says a secondary-market acquirer of a seized token holds an unvested position and cannot redeem until completing an issuer-controlled vesting process, so a liquidator must instead sell on Base, find an eligible redemption counterparty, or hedge while closing the position.
Thin secondary depth compounds that constraint. LlamaRisk's Sept. 17 data, gathered before the market activated, put each token's Base sale depth at roughly $0.27 million to $1.08 million for a 2% price impact — a dated snapshot, not a guarantee of what a liquidator could sell now. If a reopening gap exceeds the modeled buffer, or the seized tokens can't be sold or hedged at the assumed price and speed, the shortfall lands on the Equities Hub's opt-in USDC suppliers rather than the wider Aave market.
