Chainlink has launched Data Feeds that supply continuous market pricing for Coinbase Tokenized Stocks on Base, allowing decentralized finance protocols to accept the assets as collateral. The feeds cover four tokenized equities: NVDAc, METAc, AAPLc and GOOGLc, which provide exposure to Nvidia, Meta, Apple and Alphabet shares.

Reliable price data is required for lending markets to set borrowing limits, track collateral values and manage liquidations. With Chainlink’s feeds in place, supported tokenized stocks can move beyond holding or secondary-market trading and become usable in borrowing applications, decentralized exchanges and structured products on Base.

How the Integration Works

Coinbase issues the products as B20 tokens on Base. Each token represents a beneficial interest in a corresponding U.S.-listed share held through a segregated custody account. The issuer, Coinbase Onchain SPV Ltd., operates under approval from the Abu Dhabi Global Market’s Financial Services Regulatory Authority. Alpaca Securities serves as the broker and custodian for the underlying equities.

Chainlink’s feeds report the total return value of each B20 token. The calculation combines the underlying stock’s market price with a multiplier drawn from Coinbase’s onchain oracle registry. This approach accounts for corporate actions such as dividend reinvestment, which can change the amount of equity represented by one token over time.

Applications access the data through Chainlink’s standard V3 aggregator interface. Developers are advised to verify token contract addresses rather than rely solely on ticker symbols.

Expanded Utility for Tokenized Equities

Holders of eligible tokenized stocks can deposit them into supported lending protocols and borrow other digital assets against their value, subject to each platform’s collateral requirements and risk parameters. Base hosts lending services from protocols including Aave, Morpho and Euler that are providing or preparing markets for B20 assets. Trading infrastructure is available through platforms such as Aerodrome, 0x, 1inch, KyberSwap and CoW Swap.

The arrangement links traditional equity exposure with onchain finance. Coinbase supplies the tokenized stocks, Base supplies the blockchain environment, and Chainlink supplies the pricing data that smart contracts require to value and manage the assets as collateral.

Trading Hours and Data Considerations

Although Base operates continuously, the underlying U.S. equities follow standard market sessions. Chainlink’s equity feeds deliver 24-hour coverage from Monday through Friday by combining regular-session, extended-hours and overnight data. Coverage is strongest during regular U.S. trading hours and thinner overnight. Valuations may remain static over weekends when equity markets are closed.

Chainlink applies session-aware smoothing during transitions between trading periods. This can dampen brief spikes from low liquidity but may cause the reported value to lag during rapid moves. Protocols are responsible for setting their own risk limits and assessing whether each feed suits their collateral markets.

Access Restricted to Non-U.S. Investors

Despite representing shares listed on U.S. exchanges, the tokenized stocks are not offered to U.S. persons. The securities have not been registered under the Securities Act of 1933. Coinbase relies on Regulation S for offshore offerings and prohibits sales or delivery in the United States or for the benefit of U.S. persons.

U.S. customers can access conventional stocks and exchange-traded funds through Coinbase’s separate brokerage service, which operates independently of the Abu Dhabi-issued B20 products available on Base.

The addition of collateral functionality broadens the role of these tokenized equities within Base DeFi, converting them from primarily trading instruments into programmable assets that can participate in lending and other onchain financial applications.
