How borrowing against tokenized stocks works on Base

Aave V4 and Morpho both let eligible non-US holders post Coinbase Tokenized Stocks on Base as collateral for USDC loans. Aave lists seven tokens as collateral-only; here is how each venue prices, liquidates and limits them.

How borrowing against tokenized stocks works on Base - Tutorial and guide

On Oct 12, Base's X account posted a clip from an AGM session on tokenization, quoting a speaker: "The lend and borrow side is interesting. The ability to do a levered long on a stock, or to be able to short it." The same day, Jesse Pollak wrote that "any brokerage can now build global credit on top of tokenized stocks." This guide covers what the lending side of Coinbase Tokenized Stocks on Base looks like today, using each venue's own documentation. Base is the network; Aave and Morpho are the two lending venues covered here.

What you are posting as collateral

Coinbase is the issuer of tokenized stocks on Base. Base's tokenized stocks page describes each one as an onchain token that gives eligible users "direct economic exposure to a listed stock," issued as a B20 token and backed 1:1 by real shares held in regulated custody. The same page says the product is available "only in eligible jurisdictions outside of the US" under Regulation S, and that availability, features and rights vary by product, jurisdiction and venue. Among the apps on that page, Aave, Morpho and Euler describe lending and borrowing (Euler: "Modular lending and borrowing for tokenized stocks"), and several others offer yield strategies. This guide covers Aave and Morpho.

LlamaRisk's assessment on Aave's governance forum states that the securities may not be acquired, held, sold, transferred or delivered in the United States or for the account of any U.S. person. It names Alpaca Securities LLC, an SEC-registered broker-dealer, as holder of the underlying shares in segregated accounts, and it flags two issuer-side risks: pass-through SIPC protection for holders in an Alpaca insolvency is "expressly uncertain," and no audited financial statements exist yet.

Venue one: Aave V4's Equities Hub

Aave's announcement is dated Sept 25. It lists seven collateral tokens: AAPLc, AMZNc, GOOGLc, METAc, MSFTc, NVDAc and TSLAc. The Equities Hub holds a single USDC reserve and one lending market that pools all of them. A user can post any combination as collateral and borrow USDC, and each token carries its own collateral factor. Aave says the equities are collateral-only at launch: borrowing the tokens themselves and opening equity-against-equity positions are not enabled. More tokens and GHO as a borrowable asset need governance and risk review.

Borrowing rates on Aave V4 are variable. Per Aave's borrow documentation, the cost combines the reserve's base borrow rate with a risk premium that depends on the collateral in the position. Supply and borrow caps exist, and Aave says they "will be revisited through the risk steward process" as token supply and venue depth grow.

Eligibility follows the token: Aave says the securities are offered under Regulation S only to eligible non-U.S. persons in permitted jurisdictions.

Venue two: Morpho on Base

Morpho's Aug 24 post said Coinbase Tokenized Stocks were live on Base and "only available in eligible geos ex U.S." Its September 2026 update says stock-backed loans on Coinbase Tokenized Stocks are live on both Morpho Blue and Midnight. Midnight is Morpho's fixed-rate product; Blue is the variable-rate market.

Steakhouse, a Morpho curator, reported five USDC markets against AAPLc, GOOGLc, METAc, NVDAc and SPCXc, added to its High Yield USDC vault. Curators choose each market's parameters, so unlike Aave's single hub, collateral and limits are set market by market.

Morpho describes Midnight as "offer-based markets, not pool-based", where a borrower can offer a whole portfolio of tokenized stocks as collateral and borrow against its combined value, each portfolio acting as its own isolated market. Access gating, including jurisdiction controls, is described there as an optional market parameter applied programmatically at the market level.

How liquidation and oracle pricing work

Aave V4. A position is safe while its health factor is above 1. Below 1, a liquidator can repay part of the debt and claim collateral. Aave says the repayment is sized to bring the borrower back to a target health factor set by governance, and the liquidator bonus rises as health falls (Aave on V4 liquidations). Aave's docs say users can avoid liquidation by adding collateral or repaying (positions documentation).

Prices come from Chainlink's 24/5 tokenized equity feeds, which per Aave publish from Sunday 20:00 ET to Friday 20:00 ET. When markets are closed, the feeds hold the last published price, so collateral values do not change. Aave warns that stagnant weekend or holiday prices can still reduce position health through interest accrual alone, and that corporate actions such as stock splits trigger reserve pauses. The LlamaRisk assessment adds that the feed combines the equity price with an issuer-controlled multiplier that changes only on corporate actions, and that the affected reserve is paused during those windows.

Morpho. On Blue, a position becomes liquidatable when its loan-to-value exceeds the market's liquidation LTV, and liquidations settle at the current oracle price; the whole liquidation incentive goes to the liquidator (Morpho liquidation docs). On Midnight, each collateral asset has its own oracle and liquidation LTV, a position is liquidatable when debt exceeds the sum of collateral value times liquidation LTV, and a recovery close factor caps how much a single liquidation can repay (Midnight liquidation docs).

One structural detail from the LlamaRisk assessment matters for liquidations: only vested holders can redeem tokens for the underlying, five addresses were allowlisted as of Sept 23, and no liquidators or lending contracts had been permitted to vest. A liquidator therefore receives the token, not a route to redeem the share.

Apps built on top: Grow Credit

Michael Horenstein, founder of Grow, introduced Grow Credit on Oct 12, the post Pollak quoted. In the linked article he wrote that it lets users borrow against eligible stocks and receive funds in local currency, and that "Coinbase provides the eligible tokenized stocks. Base provides the blockchain network. Aave powers the lending." Grow states a borrowing limit of up to 55% of eligible stock value, a variable interest rate, and that loans are denominated in USD, so exchange-rate moves and conversion costs affect repayment. Its disclosures say it is not available to US persons and that collateral value declines can result in automatic liquidation of some or all pledged assets.

Risks the venues state themselves

  • Aave: borrowing is "a risk-increasing action" that lowers the health factor, and monitoring collateral is the borrower's job (borrow docs). Stale weekend prices and corporate-action pauses are listed above.
  • Morpho: Morpho's essay on tokenized stocks lists "Very diverse risk and compliance requirements" among the challenges of bringing stock lending onchain, since who may hold, lend, borrow or liquidate a stock "can vary by asset, jurisdiction, and participant." That is the problem the essay says a lending protocol must handle with different access controls and risk parameters per market, not a warning from Midnight's docs. Each Morpho market's parameters come from its curator.
  • Issuer: the LlamaRisk assessment flags the SIPC and audit points above. Base's page says rights vary by jurisdiction and that it is not an offer or recommendation.

This is a description of mechanics, not investment advice.

What the sources do not say

  • Which oracle Morpho's stock markets use, and their liquidation LTVs, are not stated in the Morpho material we could read. They are shown per market in Morpho's app.
  • Aave's collateral factors per token are not in Aave's announcement.
  • The speaker's "short" idea: Aave says borrowing the tokens is not enabled, and Morpho's material separates stock-backed lending from lending stocks out, without saying the latter is live on Base.
  • Coinbase's full list of eligible countries was not available on pages we could read.
