Aave founder: Aave V4 can reconstruct the on-chain securities financing market, targeting a market size of trillions of dollars

Aave founder Stani Kulechov stated that Aave V4 can be used to reconstruct the on-chain securities financing market. He mentioned that securities financing is one of the largest markets on Wall Street but receives relatively little attention from the outside. Securities collateralized loans have become a multi-trillion dollar business, with the U.S. repurchase market having an average daily exposure of about $12.6 trillion, secured financing reaching $1.3 trillion, wealth management securities collateralized loans exceeding $400 billion, and approximately $4.6 trillion in assets in the securities lending market being lent out, generating a record $15 billion in revenue by 2025.

Aave V4, through a "liquidity hub + modular market" structure, allows for shared liquidity at the underlying level while setting up segmented markets with different risk parameters, asset ranges, and rules at the upper level. Aave V4 can support three core securities financing scenarios: securities collateralized loans, repurchase transactions, and securities lending. Tokenized securities can be used as collateral to borrow GHO or stablecoins; repurchase transactions can borrow stablecoins using tokenized securities as collateral and achieve atomic settlement; in securities lending, the tokenized securities themselves can become borrowable assets, with lending income flowing directly to asset holders.

Stani indicated that Aave V4 could adopt a single shared liquidity hub or split multiple hubs by asset class and risk. The former has deeper liquidity, while the latter offers stronger risk isolation. He believes that the realistic path may start with unified liquidity and, as the types of collateral expand, gradually evolve into a multi-hub structure categorized by asset class and risk.
