Aave is outlining how its V4 architecture could support securities finance as more financial assets move onchain, pointing to a market that includes roughly $12.6 trillion in daily U.S. repo exposures, $1.3 trillion in margin lending and $4.6 trillion in securities lending.

According to the DeFi lending protocol, V4 could support securities-backed lending, repo and securities lending using tokenized assets and stablecoin liquidity. Founder and CEO Stani Kulechov said the upgrade can support debt instruments and tokenized stocks. The company noted that securities finance already handles tens of trillions of dollars annually in an announcement shared on X.

Aave V4 Targets Securities Finance

According to Aave, U.S. repo averages about $12.6 trillion in daily exposures. Repo is a short-term funding market in which securities are exchanged for cash alongside an agreement to repurchase them, making it a core financing mechanism for institutions. Margin lending has reached $1.3 trillion, while securities-based loans exceed $400 billion. Separately, securities lending has about $4.6 trillion of assets on loan, a market in which holders lend out securities and collect fees.

The business generated a record $15 billion in revenue during 2025. Aave said much of this activity remains outside blockchain networks, identifying custodians, lending agents, collateral managers, prime brokers and clearing houses within the existing structure.

Under V4, however, Aave separates liquidity hubs from modular spokes. Hubs provide shared capital, while spokes operate with their own assets, rules and risk settings.

Three Finance Flows Move Onchain

Aave described three potential uses for the architecture. In securities-backed lending, tokenized securities would serve as collateral for GHO or stablecoins, with asset-specific haircuts and automated liquidations. Borrowers could retain their securities while still accessing liquidity.

Repo represents a second use case. Tokenized securities could support short-term borrowing through stablecoin cash, with delivery-versus-payment settling atomically, meaning the exchange of securities and payment occurs in a single transaction rather than as separate settlement legs. The architecture could also support securities lending, in which tokenized securities become borrowable assets and borrowing fees are directed toward suppliers.

Two Models for Liquidity Hubs

Aave outlined two possible market structures for V4. The first uses a single shared liquidity hub beneath specialized spokes. The second uses several hubs divided by asset category and risk profile. Treasury collateral, for example, could route through a lower-risk hub, while equity collateral moves through a separate hub with different parameters. Aave said this approach could separate risks while allowing spokes to connect with multiple hubs.

The company also cited existing infrastructure supporting the proposal. Aave said its protocol secures about $23 billion in liquidity — a fraction of the trillion-dollar exposures it cites in traditional securities finance — while GHO operates as its native dollar asset. Additionally, Aave said Horizon has surpassed $500 million in total deposits for RWA-backed loans, situating the proposal within Aave's broader push to bring tokenized real-world assets into onchain lending.

Kulechov said V4 could support securities finance as markets move toward onchain settlement.
