Aave remains at the forefront of DeFi lending, boasting $24.51 billion in total value locked and $17.526 billion borrowed, according to DefiLlama. This gives it a significant margin over its closest competitor, Morpho, with about a 4.1 times difference, while Spark follows with $967.52 million in borrowed funds.
In 2025, Aave secured 61.5% of the active loan market share and 52.4% of the lending TVL share. However, within two months, three key teams instrumental to its code, governance, and risk management either announced exits or began phasing out. BGD Labs declared on February 20 that it would stop contributing due to misaligned environments, starting off-boarding by April 1. ACI decided on March 3 not to renew their contract, opting for a four-month wind-down period. Chaos Labs revealed on April 6 its decision to end engagements independently, after managing risks across Aave V2 and V3 since November 2022.
Aave’s governance documents outline an operational model where ACI focused on growth, Chaos Labs on risk, and BGD Labs on technical and security verification, with LlamaRisk and the Protocol Guardian acting as risk guardians. The sequential departure of these teams challenges this documented operating model at a crucial point.
This situation is significant because Aave maintains its leadership role in DeFi lending, not just a niche governance issue. If it can manage these exits without further operational issues, its dominance appears sustainable. However, if not, competitors like Morpho and Spark could gain an opening as Aave expands through V4, GHO, and new products.
A misconfigured CAPO oracle on March 10 caused the effective wstETH exchange rate to fall about 2.85% below market value, leading to $10.938 million in liquidations across 34 accounts, totaling approximately $26.6 million in volume. Aave’s review confirmed no bad debt but proposed a reimbursement of 512.19 ETH, costing the DAO 358.56 ETH—a significant governance issue.
Chaos Labs pointed to the transition from V3 to V4 as adding genuine operational strain. With V4 live on Ethereum and having conservative caps, managing both versions increases risk management needs, estimated at a minimum budget of $8 million, compared to their prior $3 million engagement and Aave’s 2025 revenue base of about $142 million.
Aave Labs is swiftly moving to fill the gap. The “Aave Will Win” ARFC suggests that Labs take over governance tooling, DAO GitHub maintenance, Guardian coordination, CAPO pricing management, bridge adapter maintenance, technical reviews, and much of the proposal infrastructure once managed by BGD and ACI. Aave argues for a smaller, more defined set of responsibilities under Labs to ensure faster execution and clearer accountability.
Aave’s V4 underwent about 345 days of security review involving four audit firms and independent researchers, revealing no critical findings. The protocol retains $250 million in Umbrella first-loss coverage. BGD will provide a two-month advisory retainer through May 31, focusing on security. LlamaRisk continues its role with additional risk-agent responsibilities.
The bullish scenario suggests Aave can maintain or grow its lending market share if consolidation succeeds, navigating smoothly through V4 cap raises and avoiding operational incidents while expanding GHO, Horizon, and other initiatives.
Conversely, the bearish outlook highlights risks as key contributors who built the operating layer for connecting risk models to production exit. Chaos Labs managed loans with no significant bad debt since November 2022, BGD handled technical architecture, and ACI managed governance flow. If Aave Labs fails to replicate this operational density amid its contributor exits, competitors could gain an advantage.
Morpho has $7.337 billion in TVL and $4.29 billion borrowed, expanding through a modular architecture distinct from Aave’s unified liquidity model. While the borrowing gap is significant, slow premium leakage can accumulate over time, favoring alternatives during visible governance transitions.
A three-scenario framework outlines potential outcomes for Aave post-contributor exits: extending lending dominance or encountering confidence-damaging operational incidents. If a V4 incident occurs before Labs demonstrates full control of operations, the narrative shifts from governance transition to a confidence-pricing event.
