Aave Labs has proposed a significant restructuring of the protocol's security incentive model, moving away from a unified bug bounty program toward a modular, subsystem-specific approach. The shift reflects a fundamental reality: as Aave has evolved from a single lending protocol into a sprawling ecosystem spanning multiple versions, chains, and infrastructure layers, the notion of applying uniform severity criteria and payout structures across all codebases has become increasingly untenable. Each component—from Core V3 to the nascent V4 implementation to cross-chain deployments on Aptos—operates within distinct threat models that demand tailored security responses.
The restructuring parcels out security oversight across three major platforms, each selected for its fit with specific subsystems. Immunefi will continue managing the foundational infrastructure: Core V3, the legacy V2 contracts, GHO stablecoin, and non-liquidity protocol components. Sherlock assumes responsibility for both Aave V4 and the App Stack, the latter being increasingly critical as front-end vulnerability vectors grow more sophisticated. Cantina takes on the specialized challenge of Aave V3 on Aptos, a cross-chain implementation that requires auditors versed in Move's distinct security landscape. This fragmentation allows each platform to calibrate its severity definitions, submission processes, and reward structures to match the actual economic impact and attack surface of the underlying code, eliminating the operational ambiguity that plagued a monolithic program.
The motivation runs deeper than mere organizational tidiness. When a single bounty framework governs radically different systems, researchers face genuine confusion about whether a vulnerability in non-critical infrastructure warrants the same scrutiny as a flaw in core lending mechanics. Conversely, reviewers struggle to apply consistent judgment across disparate codebases. By segmenting programs, the DAO can now set bounty ceilings that reflect each component's strategic importance—V4, positioned as the protocol's future, receives compensation aligned with that vision, while established systems get frameworks proportionate to their role as battle-tested infrastructure. The proposal also consolidates funding responsibility: previously, Aave Labs subsidized the Aptos bounty program; the restructuring brings this cost into the DAO treasury, a procedural clarification that improves transparency around security spending.
This modular approach preserves flexibility as Aave evaluates platform performance across competing security service providers, allowing the DAO to pivot deployment strategy for specific subsystems without wholesale restructuring. The move signals that mature DeFi infrastructure requires security sophistication that matches its operational complexity, where one-size-fits-all incentive models inevitably create blind spots.
