Coinbase Onchain SPV Ltd. has introduced tokenized stocks on the Base blockchain, utilizing the B20 token standard to represent real-world assets. These assets, which include shares of companies such as Nvidia, Meta, Apple, and Alphabet, are backed by a one-to-one custody arrangement with Alpaca Securities LLC. Chainlink provides the necessary price feeds to value these assets by calculating total return values, accounting for corporate actions like dividends through an on-chain multiplier. Following the initial deployment of price feeds, the utility of these assets expanded as the Aave V4 protocol integrated seven tokenized stocks—including Amazon, Microsoft, and Tesla—into its Equities Hub. This integration allows eligible non-U.S. investors to use these equities as collateral to borrow USDC stablecoins. At the launch As of mid-October 2026, the Equities Hub, the market is restricted to USDC borrowing, Hub has seen increased adoption, with specific collateralization ratios varying by stock, ranging from approximately 65% for Tesla $9.57 million in tokenized Magnificent 7 supply deposited and Meta borrowing wallets growing from 8 to 79% for Microsoft. A notable risk 144. Citi Research has identified with this integration is the mismatch between the 24/7 nature of DeFi and the 24/5 schedule of U.S. equity markets; during weekends and holidays, oracle prices remain static, meaning collateral valuations may not reflect real-time market shifts until the next session begins. Recent developments indicate the Aave lending market on Base allows users as a leader in tokenized financial infrastructure, noting that such assets enable “atomic delivery versus payment,” which reduces exposure to borrow up delivery failures compared to $21 million in USDC using these seven Coinbase-issued assets. The traditional settlement cycles. Despite this growth, the market currently maintains a $32 million USDC supply cap. However, the weekend pricing gap presents cap and a specific $21 million borrowing cap. A notable risk for USDC lenders: remains the “weekend gap”: because Chainlink price feeds freeze at Friday’s close and do not update until Sunday evening, significant market news occurring over the weekend could leave positions undercollateralized without the ability to trigger immediate liquidations, potentially resulting in bad debt.
