Chaos Labs announced it is ending its three-year engagement with Aave, saying a fundamental disagreement over risk management for the upcoming V4 architecture, the departure of other core contributors, and legal exposure with no clear regulatory safe harbor drove the decision. Chaos — which priced every loan on Aave since Nov 2022 — said retooling risk infrastructure for V4 requires substantially more investment; Aave Labs offered $5M while Chaos estimated it needed at least $8M to cover V3, V4 and institutional work. This is the third core-contributor exit (after BGD Labs and the Aave‑Chan Initiative), raising concerns about loss of institutional knowledge during a prolonged V3→V4 migration. Chaos warned operating both versions doubles workload and flagged intensive monthly Risk Oracle parameter updates, and it pledged a structured offboarding plan. The piece also notes Aave’s historical TVL and volume metrics and that AAVE trades near $96 (up ~5% 24h, ~73% below its Aug 2025 high).

Facts: Chaos Labs is ending its engagement after three years citing a fundamental disagreement on risk management as Aave moves to V4; other core contributors have departed (third exit); Chaos says retooling for V4 requires substantially more investment and estimated it needed ≥$8M while Aave Labs offered $5M; Chaos flagged doubled workload operating V3 and V4 and intensive monthly Risk Oracle updates; Chaos promised a structured offboarding. These facts point to increased operational and execution risk for Aave during the V3→V4 migration and funding shortfall, supporting a modestly negative sentiment and moderate market impact.
