The blue-chip lending protocol Aave has officially launched its next-generation governance system — Aave Governance V3 — setting a new benchmark for decentralized autonomous organization (DAO) operations. Designed to enhance efficiency, reduce costs, and improve cross-chain functionality, this upgrade marks a significant evolution in on-chain governance infrastructure. With over $6.5 billion in total value locked (TVL), Aave ranks among the top DeFi protocols, making its governance innovations highly influential across the ecosystem.
This article provides a comprehensive breakdown of Aave Governance V3, comparing it with its predecessor (V2), detailing its architecture, workflow improvements, and core benefits — all while highlighting why it serves as a model for future DAO frameworks.
Why Aave’s Governance Model Matters
As one of the most trusted protocols in decentralized finance, Aave's governance design prioritizes security, decentralization, and operational resilience. Unlike many projects that rely on multi-sig wallets or centralized control for critical upgrades, Aave employs a robust, code-enforced governance process that minimizes human intervention and single points of failure.

Aave Governance V2, active since 2020, has already proven its reliability by successfully enabling complex initiatives such as the launch of GHO — Aave’s native over-collateralized stablecoin — entirely through community-driven proposals. This track record underscores the maturity and scalability of Aave’s governance framework, making V3 not just an upgrade, but a strategic leap forward.
Understanding Aave Governance V2: Foundation and Limitations
Before diving into V3, it’s essential to understand the structure and challenges of the previous version.
Core Components of Aave Governance V2
- AaveGovernanceV2: Manages proposal creation, parameter configuration, and lifecycle tracking.
- Short Executor: Executes low-risk changes (e.g., adding new collateral assets) with lower voting thresholds for faster iteration.
- Long Executor: Handles high-impact modifications (e.g., core logic updates) requiring higher quorum and approval rates.
- GovernanceStrategy: Defines voting eligibility, supporting both AAVE and stkAAVE (staked AAVE) tokens.
- Aave Guardian: A multi-signature emergency override controlled by ten trusted addresses, capable of halting malicious proposals or pausing protocol functions during crises.
Governance Workflow in V2
- Proposal Submission: Begins with community discussion and temperature checks on forums.
- ARFC (Aave Request for Comments): Drafts formal Aave Improvement Proposals (AIPs) with code, followed by off-chain Snapshot voting.
- AIP Submission: Finalized proposals are submitted to the on-chain governance contract.
- Delay Period (~24 hours): Allows snapshotting of token balances to determine voting power.
- On-Chain Voting: Conducted on Ethereum with tiered thresholds based on proposal impact.
- Execution Lock Period: After approval, a time lock prevents immediate execution.
- Proposal Execution: Triggered manually by external actors using Short or Long Executor contracts.
- Cross-Chain Execution: For non-Ethereum networks, requires additional manual cross-chain triggers.
Key Challenges in V2
Despite its success, Governance V2 faced two major limitations:
- High Voting Costs: On Ethereum, each vote costs approximately $5 under normal gas conditions — prohibitively expensive for small holders. During network congestion, fees can surge 5–10x.
- Increased Token Transfer Fees: To support voting mechanics, AAVE and stkAAVE tokens stored historical balance data, increasing gas costs for every transfer by up to 75%.
These inefficiencies highlighted the need for a more scalable, cost-effective governance solution — paving the way for V3.
Aave Governance V3: Key Upgrades and Architecture
Aave Governance V3 retains the core principles of decentralization and security while introducing transformative improvements in efficiency and accessibility.
Key Differences Between V2 and V3
| Feature | V2 | V3 |
|---|---|---|
| Proposal Creation | Code submitted after proposal initiation | Code must be pre-deployed and registered |
| Voting Network | Exclusively Ethereum | Multi-chain (Polygon, Avalanche, Arbitrum, Optimism, etc.) |
| Voting Cost | High (Ethereum gas) | Drastically reduced (e.g., ~$0.05–$0.10 on Polygon) |
| Token Overhead | Balance history tracking increases transfer cost | No historical tracking; cheaper transfers |
| Automation | Manual execution steps required | Automated via Aave Robot |
| Cross-Chain Support | Limited and manual | Native integration via cross-chain infrastructure |
Additionally, voting rights now extend to a broader set of tokens: AAVE, aAAVE (Aave V3 tokens), stkAAVE, and stkABPT.
How Aave Governance V3 Works: Step-by-Step Process
The new governance flow leverages cross-chain communication and automation to streamline decision-making:
- Code Submission: Proposers deploy executable code on the target network (e.g., Avalanche) and register it with the controller contract — permissionless and open to anyone.
- Proposal ID Issuance: Upon successful registration, the system issues a unique proposal identifier.
- Proposal Creation on Ethereum: Qualified proposers use the ID to create an official proposal on Ethereum’s core governance contract.
- Proposal Activation: After a ~24-hour delay, the Aave Robot or any address triggers the snapshot of blockchain state.
- Block Hash Submission: The Ethereum block hash is sent to Aave’s cross-chain messaging layer.
- State Settlement on Target Chain: The voting network receives and verifies the state (including block hash and token balance proofs).
- Voting Begins: Users vote via the “vote machine” contract deployed on the target network.
- Vote Submission: Token holders cast votes off-Ethereum, significantly reducing gas fees.
- Voting Closes: The Aave Robot or another address finalizes the voting period.
- Result Settlement: Vote counts (“yes”/“no”) are relayed back to Ethereum via cross-chain infrastructure.
- Execution Readiness: Core governance contract validates results and prepares for execution.
- Code Execution: The Aave Robot executes the update on Ethereum.
- Cross-Chain Deployment: Updates are propagated to other chains via respective executor contracts.
- Queueing for Non-Ethereum Networks: Changes are queued on target chain controllers.
- Final Execution: Once time locks expire, the update is applied on the target network.

This end-to-end automation reduces reliance on individual actors and enhances reliability across chains.
Core Components of Aave Governance V3
- Ethereum Core Governance Contract: Central hub for validation, voting power determination, rule enforcement, and cross-chain message routing.
- Target Network Governance Contracts ("Vote Machines"): Handle voting logic, proposal interaction, and result reporting on non-Ethereum chains.
- Cross-Chain Communication Infrastructure: Enables secure, bidirectional messaging with customizable payloads and emergency override capabilities.
- Aave Robot: An automation agent powered by Chainlink Automation that triggers key governance actions — fully funded by Aave DAO to eliminate user friction.
To support this new system, BGD Labs has released an open-source frontend interface at vote.onaave.com, along with publicly available GitHub repositories for community contributions.
Advantages of Aave Governance V3
1. Drastic Reduction in Voting Costs
By shifting voting to low-cost Layer 2 networks like Polygon or Arbitrum, individual voting costs drop to $0.05–$0.10, about 100x cheaper than V2. There’s even potential for fully subsidized voting, where the DAO covers all transaction fees — estimated at just $750 for 10,000 participants.
2. Lower Token Transfer Fees
With no need to store historical balance snapshots for voting purposes, transfers of AAVE and stkAAVE tokens become approximately 75% cheaper, improving usability and adoption.
3. Permissionless Automation
Critical steps like proposal activation, state verification, and execution are automated via the Aave Robot, reducing delays and human error.
