Base launches carry trade vaults for Coinbase tokenized stocks

Two days after Coinbase’s tokenized stock product went live on Base, the ecosystem already has carry trade vaults layered on top of it.

The vaults, developed by third-party protocols including 628 Labs, Superform, IPOR, and Portals, allow users to generate yield by lending and borrowing against tokenized equity positions. The underlying product they plug into, Coinbase Tokenized Stocks, launched on Base on August 24, 2026 under the B20 token standard.

What tokenized stocks on Base actually are

B20 tokens represent a 1:1 claim on real U.S. shares held in regulated custody by Alpaca. The initial lineup covers four of the most traded names in traditional markets: Apple (AAPLc), Nvidia (NVDAc), Meta (METAc), and Alphabet (GOOGLc).

Unlike earlier tokenized equity experiments that required custom smart contracts for every individual asset, B20 tokens are designed to plug into existing DeFi infrastructure without bespoke engineering work. Aave, Morpho, Euler, and Aerodrome all accepted these tokens on day one. Chainlink handles the price feeds, which matters for lending markets where accurate real-time valuations determine whether a position gets liquidated.

The practical result: someone who owns NVDAc can use it as collateral to borrow a stablecoin, deploy that stablecoin into a yield strategy, and effectively hold a leveraged Nvidia position with an attached yield stream.

On launch day alone, roughly $4.55 million worth of tokenized stocks were minted, approximately $3.06 million in DEX liquidity was seeded across trading pairs, and total trading volume hit $10.8 million.

Why the carry trade vaults matter

The protocols building these vaults are not Coinbase itself. Coinbase created the tokenized stock infrastructure and the B20 standard; independent teams then built yield products on top of it.

Superform specializes in aggregating yield vaults across chains. IPOR focuses on interest rate derivatives and lending optimization. 628 Labs and Portals round out a builder set that collectively covers different angles of the yield stack.

The 24/7 trading aspect of tokenized stocks also opens a specific carry opportunity that traditional finance cannot replicate. U.S. equity markets close on weekends and holidays. B20 tokens trade continuously. A position opened on a Friday afternoon can be managed, rebalanced, or unwound on a Sunday, without waiting for the New York Stock Exchange to ring its bell Monday morning.

The bigger picture for tokenized real-world assets

Coinbase’s position as a regulated U.S. entity changes the legal surface area. Earlier tokenized stock products operated from offshore venues with ambiguous regulatory standing. A product launched by the same company that holds a U.S. broker-dealer license and is publicly traded on Nasdaq carries a different kind of institutional credibility.

The integration with Chainlink price feeds is not a minor detail. Lending protocols like Aave and Euler require reliable oracles to function safely. Bad price data is how exploits happen. By sourcing pricing from Chainlink on launch, the product skips one of the most common attack surfaces in early-stage DeFi deployments.
