Borrowing USDC Against Tokenized Stocks on Aave V4: What the Base Market Covers and What to Check

Aave V4 on the Base network now has a market where certain tokenized U.S. stocks can serve as collateral for borrowing the stablecoin USDC. Aave Labs describes it in a blog post dated Sept. 25, 2026, and the project's changelog lists the Base deployment in an entry dated Oct. 7, 2026. This article uses both documents as written and does not reconcile the two dates. It explains how the market works, who can use it, and what an independent risk review says to watch.

What the market is

The changelog says Aave V4 on Base deploys an Equities Hub with a "MAG7 Spoke" listing USDC and seven tokenized equities: AAPLc, AMZNc, GOOGLc, METAc, MSFTc, NVDAc and TSLAc. In Aave V4's design, a hub holds the pooled assets and a spoke is a lending market connected to it. Aave's post says this hub holds one USDC reserve and one lending spoke.

Users can post any mix of the seven tokens as collateral, which is an asset locked to secure a loan, and borrow USDC against it. Each token has its own collateral factor, the share of its value that counts toward borrowing power. The tokens themselves cannot be borrowed, and positions that borrow one equity against another are not enabled. Aave says more tokens and borrowing of its GHO stablecoin are expected over time, subject to governance and risk review.

What the tokens are

These are Coinbase Tokenized Stocks. Aave's post says each token represents a certificate issued by Coinbase Onchain SPV Ltd. The underlying shares are held by Alpaca Securities LLC, an SEC-registered broker-dealer, in custody accounts in the issuer's name, and the issuer holds them as trustee for token holders. Aave also says dividends are reinvested into the token's claim and not paid out as cash, and that stock splits are handled the same way through a multiplier that changes only on corporate actions.

Who can use it

Aave's post states that Coinbase Tokenized Stocks are available in eligible geographies outside the United States, and that they are offered under Regulation S only to eligible non-U.S. persons in permitted jurisdictions. U.S. persons are not eligible, and the post gives no list of permitted countries. Readers should check their own eligibility with the issuer before acting.

How the price feed and weekends work

Aave says its market stays open 24 hours a day, every day. Prices come from Chainlink's 24/5 tokenized equity feeds, which publish from Sunday 20:00 ET to Friday 20:00 ET. Over weekends and U.S. market holidays, the feeds hold the last published price. Aave says collateral values do not change during that window, and a position's health factor, the ratio that shows how close a loan is to liquidation, can fall only through interest accruing on the debt.

It follows that any gap between the last Friday price and the price when markets reopen can arrive in a single step. Aave also says the affected reserve is paused during corporate actions such as stock splits until the new multiplier is applied.

Risks flagged in the independent review

Aave's governance forum hosts a risk assessment of these tokens by LlamaRisk, a risk service provider to Aave. Dated Sept. 24, 2026, it makes several points that bear on lending against these tokens. Aave's own risks page covers general lending risks.

• Redemption depends on a process. Holders who acquire the tokens on the secondary market are "unvested," with exposure to the underlying shares but no redemption, voting or information rights until they complete the issuer's vesting process. The assessment says vesting is decided on the issuer's behalf and can be revoked.
• Liquidation is a question mark. If a loan's health factor falls too low, a liquidator takes part of the collateral to repay the debt. The assessment cites Coinbase's follow-up response saying no liquidation contract had yet been permitted to vest, with processing time described only as "short" and no committed deadline.
• Limited trading venues. The tokens are not admitted to trading on any exchange and move through DeFi markets that the review says are not currently regulated in Abu Dhabi Global Market, where the offering was approved.
• Unclear insolvency protection. The prospectus, as quoted in the review, says it is uncertain whether SIPC protection would reach token holders if the custodian failed.
• The issuer is a special-purpose company. The review says Coinbase Onchain SPV Ltd is not described anywhere in the prospectus as licensed, authorized or exempt, and it quotes Coinbase's own response calling it an "Unregulated SPV." The review adds that the offering and one related entity are supervised.

What remains unknown

This article reviewed Aave's post, its changelog, and the first part of a long assessment thread, so it may not reflect later updates, including parameter changes or liquidator onboarding. The documents do not state the collateral factors in the sections reviewed. Nothing here suggests that tokenized stocks are safe collateral, and this article makes no statement about the price of any stock or token.
