What happened.

Aave V4 on Base now accepts Coinbase tokenized stocks as collateral for USDC loans available to non-U.S. users. The listed stocks include Apple, Nvidia and Tesla, alongside four others, according to [The Block’s report](https://www.theblock.co/news/defi/2026-09-25-aave-v4-on-base-adds-coinbase-tokenized-stocks-as-collateral-for-usdc-loans-416372).

Separately, Ethena is adding Binance bStocks and equity perpetuals to the basis trade behind USDe’s backing, according to [The Block’s report](https://www.theblock.co/news/deals/2026-09-25-ethena-expands-usde-backing-strategy-into-bstocks-and-equity-perpetuals-on-binance-416367). The record describes Aave’s collateral use as active and Ethena’s addition as underway.

Why it matters.

The two developments give tokenized equities distinct roles in DeFi: collateral for a loan and part of a stablecoin backing strategy. That makes the treatment of equity-linked positions relevant to both lending and backing risk.

The practical questions are how the tokens are priced, who can use them, and how redemption works. For Aave, those details bear on liquidation. For Ethena, they bear on how the equity positions fit into USDe’s backing. The supplied record does not answer those questions.

What to watch

Watch for Aave’s published collateral terms and evidence of how the equity tokens are priced and redeemed. For Ethena, watch for confirmation that the bStocks and equity perpetuals have entered the USDe backing strategy and for details of their role in it.
