Coinbase Tokenized Stocks Become Collateral for USDC Loans…

Aave has launched an Equities Hub on Base that lets holders of Coinbase-issued tokenized US stocks use those tokens as collateral for USDC loans, moving the assets beyond simple onchain holding and trading. The hub accepts tokenized shares tracking Apple, Amazon, Alphabet, Meta, Microsoft, Nvidia and Tesla, and is open to eligible users outside the United States in permitted jurisdictions.

At launch, only deposits and borrowing are enabled: users can post the equity tokens as collateral and draw USDC against them, but the stocks themselves cannot be borrowed. That keeps the initial market focused on stock-backed stablecoin lending rather than shorting or borrowing one equity against another.

"Public equities are one of the largest pools of capital in the world, and tokenization is starting to bring that capital onchain," said Stani Kulechov, founder and CEO of Aave Labs.

Deliberately small starting capacity

The market opens with tight limits. Collateral caps across the seven equities total roughly $29 million, while the USDC supply cap is approximately $32 million and the borrow cap about $21 million. Collateral factors range from 65% to 79% depending on the stock, setting how much USDC a user can borrow against each tokenized share and providing a buffer against moves in the underlying price.

The seven stocks sit in a dedicated hub built on Aave V4's Hub and Spoke architecture. A single USDC reserve supplies borrowing liquidity, while risk parameters stay specific to each equity, so problems with one stock can be contained without automatically changing the settings for the other six. The launch follows Coinbase's August start of rolling out tokenized US equities on Base, and completes a step that was missing when Chainlink was chosen to price those tokens: oracle data supplied valuations, but Aave V4 was needed before stock-backed lending could operate.

One structural wrinkle is that the tokens can change hands onchain around the clock, while the underlying US shares trade mainly in defined sessions. Aave's initial setup uses Chainlink tokenized-equity feeds that publish prices 24 hours a day during the five-day trading week and hold their last values over weekends and market holidays. An equity event during a closed market could therefore shift a borrower's loan health sharply once pricing resumes, which is why conservative caps and collateral factors are central to the design.

Aave, which says it has processed more than $1 trillion in cumulative loans, may add further Coinbase-issued stocks to the hub over time and has left room for GHO to become borrowable subject to governance and risk review. The $29 million initial collateral limit is small next to global equity markets; the real test is whether investors choose to borrow against tokenized shares.
