Two-thirds of all dollars borrowed onchain are now routed through Ethereum, highlighting its dominance in the DeFi market. According to recent data from Messari, Ethereum and its associated liquid staking tokens constitute 67% of the entire decentralized finance borrowing ecosystem. This significant share has grown amidst a challenging lending market, which has seen borrowing activity decline by around 50%.
As of May 2026, total outstanding onchain lending stood at approximately $23 billion, a noticeable decrease from the peak of $46 billion reached in 2025.
What does this 67% share consist of? The majority is not limited to basic ETH serving as collateral. A substantial portion derives from liquid staking tokens, like stETH provided by Lido and similar platforms. Essentially, those who stake their assets enjoy the benefits of staking yields while utilizing these tokens as leverage for borrowing, a strategy known as double-dipping.
Aave plays a critical role in this financial landscape, acting as a leading lending protocol that facilitates most of the borrowing activity on Ethereum. With Ethereum functioning as the primary infrastructure for decentralized credit, Aave serves as the toll booth for transactions, collecting fees that sustain its operational model.
The innovative nature of liquid staking tokens further enhances this dynamic. These tokens yield returns when used as collateral, rendering loans secured by them more appealing for both borrowers and lenders alike. When a borrower pledges stETH, they effectively lower their cost of borrowing by the staking yield they earn simultaneously.
Why does this matter for the DeFi landscape? Holding a 67% market share in a $23 billion onchain lending space firmly establishes Ethereum as the foundational pillar of decentralized lending. As the volume of ETH staked and tokenized continues to expand, the supply of quality DeFi collateral also increases, which enhances liquidity and makes it an attractive option for lending activities.
