Many people still think of RWA as simply “moving stocks onto the blockchain and issuing a token, then calling it done.”

With Aave V4, it takes one more step forward: what it aims to do is securities finance—turning everything from bonds into tokenized stocks, with direct on-chain collateralization, borrowing, and lending.

In other words, what gets put on-chain isn’t just “asset certificates,” but the entire foundation of the credit market.

When both stocks and bonds can be used on-chain as collateral for borrowing and lending, the traditional layers of dealer spread and custody are effectively being reshaped.

For crypto, this means DeFi lending and borrowing is officially moving from the “native coin collateral” paradigm into the TradFi lending and deposit order book—Aave wants to be the new underlying infrastructure for this space.

The risks are also obvious: regulation, counterparties, and off-chain asset title/verification haven’t been solved yet.

But the direction has already been made clear.
