Aave Founder: Aave V4 Can Reforge On-Chain Securities Lending Market, Targeting Market Size of Trillions of Dollars

June 20: Aave founder Stani Kulechov revealed that Aave V4 has the potential to overhaul the on-chain securities financing market, labeling this space as one of Wall Street’s largest but most under-the-radar sectors. Securities-backed lending is already a multi-trillion-dollar industry, per Kulechov: the U.S. repo market boasts an average daily outstanding of around $12.6 trillion, margin lending hits $1.3 trillion, wealth management securities-backed lending exceeds $400 billion, and the securities lending market holds roughly $46 trillion in lendable assets—with projected revenue set to hit a record $15 billion by 2025. Aave V4 operates on a "Liquidity Hub + Modular Market" framework: base-layer liquidity is shared across the system, while top-layer markets are segmented by distinct risk parameters, asset sets, and governing rules. The platform supports three core securities financing use cases: securities-backed lending (where tokenized securities serve as collateral to borrow GHO or stablecoins), repo transactions (borrowing stablecoins against tokenized securities for atomic settlements), and securities lending (tokenized securities themselves become lendable assets, with all lending profits going directly to asset holders). Kulechov added that Aave V4 can either use one single shared liquidity hub or split into multiple hubs grouped by asset category and risk: the single hub offers deeper liquidity, while multiple hubs provide stronger risk isolation. His predicted trajectory? Start with unified liquidity, then evolve into a multi-hub structure over time as new collateral types are added.
