Key Takeaways
-
Aave and Morpho stand at the forefront of DeFi lending, while Spark and Sky provide foundational stablecoin credit.

The introduction of Aave V4 and the KelpDAO exploit significantly shifted risk perspectives throughout the year.
-
Collateral quality and bridge exposure currently hold just as much importance as protocol audits.
Decentralized finance (DeFi) lending continues to be the second-largest sector by locked value. According to CertiK Skynet metrics, lending TVL reached $50.2 billion on September 8, marking a 21% increase over the month. Meanwhile, DefiLlama figures indicate that total DeFi TVL stood at approximately $93.9 billion on September 21.
The following is an examination of the most influential lending platforms driving the current market.
1. Aave
Blockchain(s): Ethereum, Base, Arbitrum, Avalanche, Plasma, Monad & others
Key Features: Flash loans, hub-and-spoke markets, RWA lending, native stablecoin GHO.
TVL: ~$18.3 billion to $19.2 billion, roughly 20% of DeFi TVL
Accounting for nearly 48% of outstanding onchain loans, Aave deployed Aave V4 on Ethereum on March 30 utilizing a hub-and-spoke architecture. In this setup, Core, Prime, and Plus hubs receive feeds from spokes associated with Lido, EtherFi, Ethena, and others. The platform faced a severe test on April 18 during the KelpDAO rsETH exploit, where malicious actors deposited unbacked rsETH as collateral to borrow roughly $190 million, generating estimated bad debt between $177 million and $200 million. Because Aave’s core smart contracts remained uncompromised, the Umbrella backstop was anticipated to cover the losses, allowing TVL to recover past the $18 billion threshold.
2. Morpho
Blockchain(s): Ethereum, Base, Hyperliquid, Monad & others
Key Features: Curated vaults, isolated markets, fixed-term loans, zero borrow fees
TVL: ~$10.7 billion to $11.1 billion
Morpho secures the second position following a 14% monthly expansion. Featuring a lightweight base layer beneath curated vaults, the protocol channels retail borrowing activity through integrations with Coinbase. Its fixed-term lending options specifically cater to treasury operations requiring predictable cash flows. Because individual curators determine risk parameters, users are advised to review each vault’s specific settings beforehand, all backed by code audits from OpenZeppelin and Spearbit.
3. Spark
Blockchain(s): Ethereum, with liquidity concentrated on mainnet
Key Features: Stablecoin savings, multi-collateral lending, governance-set rates, SPK token
TVL: ~$7.4 billion total market size
SparkLend has experienced a 55% expansion in market size since January, having consolidated its liquidity onto Ethereum by shutting down an alternative chain deployment. Rather than relying on a utilization curve, Spark determines credit pricing via a public governance framework. Participants seeking stablecoin yield utilize the platform to gain exposure to Sky-aligned rates.
4. Sky LendingSky Protocol (formerly MakerDAO)
Blockchain(s): Ethereum
Key Features: Over-collateralized lending, minting of USDS and DAI stablecoins
TVL: ~$7.2 billion across the CDP category, led by Sky
Following MakerDAO’s rebrand to Sky, its lending division operates as Sky Lending. The protocol allows users to lock collateral in exchange for newly minted stablecoins. Because governance mechanisms dictate savings rates, financial returns reflect institutional policy rather than direct borrower demand, with a portion of the system backed by real-world assets.
5. JustLend
Blockchain(s): Tron
Key Features: Tron-native money market, largest non-EVM lender [NEW]
TVL: ~$3.9 billion
Operating as the premier lending platform outside the EVM environment, JustLend faces criticism primarily centered on centralization, as industry observers note the heavy influence exerted over the Tron ecosystem by Justin Sun and associated parties.
6. Compound
Blockchain(s): Ethereum, Arbitrum, Polygon, Base
Key Features: Algorithmic interest rates, community governance via COMP token
TVL: ~$1.5 billion on V3
As a pioneer of algorithmic money markets, Compound utilizes dynamically shifting interest rates alongside V3 (Comet) optimizations designed for enhanced capital efficiency. The protocol currently sits significantly behind Aave and Morpho in market share.
7. Kamino Finance
Blockchain(s): Solana
Key Features: Isolated K-Lend markets, eMode leverage, RWA and institutional products
TVL: ~$1.4 billion in lending
Serving as Solana’s leading money market, Kamino utilizes four isolated markets within K-Lend. Its eMode functionality facilitates up to 10x leverage on correlated assets, complemented by six real-world asset products introduced in December 2025.
8. Fluid
Blockchain(s): Ethereum and select layer-2 networks
Key Features: Smart collateral and smart debt unify lending and DEX [NEW]
TVL: ~$1.6 billion
Fluid integrates lending pools with decentralized exchange liquidity within a single architecture. In a September 15 survey, the protocol delivered one of the highest base USDC yields available, hovering near 5.2%.
9. Euler
Blockchain(s): 16 EVM chains
Key Features: Permissionless listing, vault isolation, risk-adjusted LTVs, DeFi-native rewards
TVL: Under $1 billion, with trackers differing
Euler V2 implements modular vaults featuring isolated risk boundaries supported by over 40 distinct code audits. The platform incorporates flexible borrowing limits to help mitigate systemic vulnerabilities.
10. Suilend
Blockchain(s): Sui
Key Features: Lending, DEX, cross-chain bridge, SEND governance
TVL: ~$160 million to $180 million
Although functioning as a prominent lender on the Sui network, Suilend has experienced a substantial decline in TVL from earlier peaks. Data from iO Charts indicates that the SEND token lost over 90% of its value over the year leading up to late July. The protocol maintains transparent liquidation protocols backed by an active bug bounty program.
DeFi Lending: What Matters in 2026
-
TVL & Market Share: Aave commands approximately 48% of outstanding loan volume, followed by Morpho, while Spark’s market presence expanded by 55% over the year.
-
Security & Auditing: The rsETH incident demonstrated that standard audits do not eliminate all risks, as the resulting bad debt stemmed from vulnerable collateral choices rather than programming errors.
-
Collateral & Bridge Risk: Restaked and bridged assets introduce hidden vulnerabilities, particularly since single-verifier bridges maintain the capacity to generate unbacked tokens. Users must thoroughly evaluate oracle feeds and collateral inventories.
-
Governance & Yield: Vault curators and native utility tokens heavily influence user acquisition. Because Sky and Spark yields are determined by governance policy, rates remain subject to administrative adjustment.
-
Institutional Credit: Innovation in the sector is currently spearheaded by fixed-term lending structures, tokenized collateral options, and hub-and-spoke frameworks.
Final Takeaway
The lending sector remains a cornerstone of decentralized finance, though the year has highlighted notable vulnerabilities. While Aave and Morpho retain dominant positions, Spark and Sky provide stablecoin credit governed by policy frameworks, leaving Compound, Kamino, Fluid, and Euler to occupy specialized niches.
Participants are advised to weigh potential yields against underlying risks by selecting audited protocols, verifying oracle and collateral integrity, diversifying positions across platforms, and monitoring liquidation thresholds closely. With roughly $50 billion currently locked, lending continues to drive the DeFi ecosystem.
