A Specter of DeFi is Haunting The World

As Ethereum breaks the $4,700 mark and charges toward its next target of $4,800, a significant milestone unfolded on August 12, 2025, within its ecosystem. The DeFi lending giant Aave announced that its active borrows have surpassed $25 billion, marking an all-time high.

This achievement, underscored by a sharp upward trend in the platform’s borrowing graph from January to August 2025, has ignited excitement across the crypto community.

This surge isn’t just about borrowing volume — Aave’s price has jumped over 25% in the past 7 days, reflecting a broader mini-bull run across Ethereum and the DeFi sector. The question now is whether this momentum can last. In this analysis, we break down the drivers behind Aave’s impressive growth and examine the shifting dynamics of the Ethereum DeFi ecosystem.

The Overall Recovery of the DeFi Sector as a Driving Force

Aave’s total borrowed amount has climbed to approximately $28.6 billion as of now, up from earlier estimates around $18 billion. This growth highlights renewed activity in the decentralized lending market.

This rise aligns with broader industry momentum. While DeFi’s TVL has not fully recovered to previous peaks, it is showing signs of improvement. As of late July, DeFi’s TVL hovered over $155 billion, approaching the peak levels seen during the 2022 DeFi Summer.

Several factors appear to be driving this resurgence:

• Yield-seeking shift: Higher borrowing and lending rates keep attracting users to DeFi over traditional finance.

• Layer 2 growth: Arbitrum, Optimism, Base, Solana, and BNB Chain make DeFi cheaper and more accessible.

• Institutional interest: Aave’s TVL nearing $50B signals rising participation from large investors.

• Market momentum: Flash loan activity is booming, with Aave processing about $7.5 billion in early 2025 and the broader ecosystem surpassing $3 trillion in total volume by the start of the year.

Aave’s near-$29 billion borrowing milestone underscores not only the platform’s strength but also the gradual revival of the DeFi sector, supported by evolving user preferences, scalability improvements, and a measured return of investor confidence.

Aave’s Product Innovations as the Core Driving Force

Aave continues to distinguish itself in the competitive DeFi landscape through relentless product innovation. Key initiatives such as the Aave V3 upgrade, the GHO stablecoin, and institutional-grade platforms enable users to maximize asset utilization across multiple blockchains, a critical factor in scaling borrowing volumes to unprecedented levels.

A key innovation driving Aave’s growth is the GHO stablecoin, a decentralized, overcollateralized asset native to the protocol. Since early 2025, GHO’s circulating supply has risen from approximately $150 million to over $335 million by August, representing a growth of around 123%, reflecting substantial adoption for borrowing and lending purposes.

Managed by the Aave DAO, interest from GHO is directed to the protocol treasury, and its fixed oracle price enhances trust and user confidence. Alongside GHO, Aave has launched institutional-grade platforms, including the Ink platform in collaboration with Kraken, providing regulated entities with compliant access to DeFi. The adoption of these tools has attracted significant institutional capital, further supporting borrowing growth.

Financially, Aave’s innovations have delivered strong results. The protocol generates approximately $131.7 million in annualized revenue, primarily derived from borrowing and lending fees. The DAO portion of this revenue is around $50.7 million, reflecting the protocol’s effective decentralized governance model.

Part of the revenue is reinvested to buy back AAVE tokens, reinforcing the ecosystem’s economic structure and rewarding token holders. With a treasury balance of roughly $259 million, Aave is well-positioned to fund future developments and sustain growth without heavily relying on external incentives.

Ethereum Chain and Cross-Chain Expansion as Technical Foundations

The increase in Aave’s borrowing activity showcases how Ethereum’s evolving L1 and L2 networks drive scalability, reduce costs, and strengthen the DeFi ecosystem.

Ethereum's L1 network remains the cornerstone of Aave's operations, hosting approximately $29 billion in TVL as of July 2025. This robust foundation ensures that Aave can support large-scale borrowing activities without disruptions, reinforcing user confidence in the platform.

Ethereum's L2 solutions, such as Arbitrum, Optimism, and Base, have significantly contributed to Aave's growth by reducing gas fees and enhancing transaction speeds.

In July 2025, Base surpassed $1.2 billion in TVL on Aave, joining the ranks of Ethereum, Arbitrum, and Avalanche in the $1B+ TVL club. These L2 networks lower gas fees to fractions of a cent, making borrowing and lending more affordable for a broader user base, a key driver behind the surge in Aave's activity.

The integration of cross-chain bridges and liquidity pools across Ethereum-compatible networks has enabled users to borrow assets seamlessly, contributing to the platform's record-breaking borrowing volumes.

This interoperability fosters a more connected DeFi ecosystem, allowing users to access a diverse range of assets and lending opportunities across multiple chains.

Stablecoin Legislation Drives Institutional Capital into Aave

The enactment of the GENIUS Act on July 18, 2025, has ushered in a new era for stablecoins, providing a clear regulatory framework that is significantly benefiting stablecoin lending and other DeFi projects. The global stablecoin supply is projected to reach $300 billion by the end of 2025.

Aave has experienced a substantial influx of institutional capital, with major players like Coinbase contributing liquidity through stablecoins like USDC.

This institutional participation is further supported by Aave’s compliance-friendly features, such as the Ink platform, which enables regulated entities to engage with DeFi safely.

The impact on user behavior is also notable. CoinGecko's data show, Aave’s daily transaction fees increased by approximately 200% over the past three months, reaching peaks of over $3 million in several months, reflecting a recovery and broader adoption of DeFi lending services.

As stablecoin usage continues to grow, Aave is well-positioned to benefit from this regulatory catalyst, further solidifying its position as a leading platform in the DeFi ecosystem.

Ethereum DeFi Ecosystem in 2025: From Aave’s Milestone to Fluid’s Breakout

Aave’s borrowing volume of nearly 29 billion is just one highlight of the renewed Ethereum DeFi ecosystem. From lending and trading to stablecoins and yield strategies, projects are introducing upgrades and innovations that signal sustainable growth.

Uniswap v4 Multi-Chain Expansion and TVL Growth

Uniswap remains a leading platform in decentralized trading. Its v4 upgrade, launched in early 2025 across multiple chains including Ethereum and Unichain, introduced major efficiency improvements that cut gas costs by over 99 percent.

These upgrades have driven significant growth:

• Spark Liquidity Layer: Handles 3.4 billion, backed by MakerDAO’s 6.5 billion US dollar stablecoin reserves.

This expansion reflects both the sector’s resilience and its contribution to the diversity of Ethereum’s DeFi ecosystem.

Fluid’s Liquidity Layer Driving Multi-Function DeFi Growth

Fluid, launched from Instadapp and relaunched in 2023, enables assets to switch between uses within its Liquidity Layer without repeated locking, significantly reducing fragmentation costs and boosting yields.

• On August 3–4, 2025, Fluid surpassed long-standing DeFi leaders, with daily on-chain trading volume reaching around $1.5 billion and capturing a 55.5% share of the stablecoin swap market across Ethereum, Base, Arbitrum, and Polygon, well above Uniswap and Curve.

• Fluid’s TVL has reached $1.65 billion, up 35% in a month. Its Smart Debt and Smart Collateral models improve capital efficiency and represent an advance in multi-purpose asset use.

Overall, Fluid has emerged as a rising force in DeFi: its unique Liquidity Layer, strong trading performance, and multi-chain expansion strategy have quickly brought the platform back into the spotlight, setting a new benchmark for stablecoin trading in the ecosystem.

Pendle’s Yield-Trading Expansion through Boros Platform

Pendle V3 release introduced the Boros platform, which converts BTC/ETH funding rates into tradable assets (Yield Units), significantly boosting user participation and capital inflows.

• TVL reached a record $8.7 billion, largely driven by Boros, which attracted over $1.85 billion in BTC and ETH deposits in its first two days.

• Around 60% of Pendle’s TVL comes from USDe strategies such as PT-USDe on Aave, which leverage a “yield-loop” mechanism to amplify returns.

Since April 2025, TVL has surged over 200%, marking a new chapter for this established project. Its innovative split-token model, Boros-powered liquidity expansion, and cross-protocol integrations reflect that DeFi innovation never stops and the ecosystem remains vibrant.
