On June 20, Aave founder Stani Kulechov stated that Aave V4 can be used to restructure the on-chain securities financing market. He noted that securities financing is one of the largest markets on Wall Street, yet it receives relatively little attention. The securities collateral loan business is already in the trillions of dollars, with the U.S. repurchase market having an average daily exposure of approximately $12.6 trillion, secured financing reaching $1.3 trillion, and wealth management securities collateral loans exceeding $400 billion. The securities lending market has about $4.6 trillion in assets available for loan, generating a record $15 billion in revenue by 2025. Aave V4 utilizes a 'liquidity hub + modular market' structure, allowing for shared liquidity at the base level while establishing segmented markets with different risk parameters, asset ranges, and rules at the upper level. Aave V4 can support three core securities financing scenarios: securities collateral loans, repurchase transactions, and securities lending. Tokenized securities can be used as collateral to borrow GHO or stablecoins; repurchase transactions can involve borrowing stablecoins against tokenized securities collateral with 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 into multiple hubs based on asset categories and risk. The former offers deeper liquidity, while the latter provides 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 type and risk.
