Governance Vaults in DeFi
A governance vault (or voting vault) is a specialized smart contract mechanism used in decentralized finance (DeFi) to manage and allocate voting power within a protocol's governance system
12. These vaults act as intermediaries that store votes or decisions from participants, often allowing users to engage in governance while simultaneously using their underlying assets for other purposes, such as providing liquidity or earning yield
12.
Types of Voting Vaults and Strategies
Governance frameworks, such as the Element Council, utilize modular voting vaults to support different participation strategies
12. Common types include:
- DeFi Vaults: These allow token holders to participate in governance while their tokens are actively used as collateral, for staking, or for liquidity provision 1.
- Locking Vaults: Users lock their tokens for a specific duration to gain voting power; typically, the longer the lock period, the greater the voting influence 1.
- Vesting Vaults: These allocate voting power to tokens that are still in a vesting period, often providing multipliers to reward long-term holders 1.
- Threshold Vaults: These determine a user's voting power based on whether their token holdings surpass a specific predefined threshold 1.
- Identity Vaults: Used to verify a participant's identity within the governance framework, often utilizing NFT standards like ERC-721 1.
- L2-L1 Vaults: These facilitate voting on the Ethereum Mainnet by using Merkle balance proofs to verify asset balances held on Layer-2 networks 1.
Role in Governance Frameworks
In modular governance systems, voting vaults serve as a bridge between the voters and the core voting contract
2.
- Voters: Community members engage with the system by interacting with specific vaults 2.
- Core Voting Contract: This central node coordinates the governance process, connecting the various voting vaults to the protocol's decision-making modules 2.
- Modules: Once a vote is processed through a vault, it can trigger actions in specialized modules, such as a TimeLock (which delays execution for community review), Treasury Managers, or Budget Contracts 2.
Incentives and Yield Integration
Some protocols integrate governance directly into their yield-generating products. For example, in the Yearn Finance ecosystem, users can lock their YFI tokens in a
Vote Locker to determine "Gauge Weights," which dictate how rewards are allocated across different liquidity vaults
3. This alignment ensures that participants who actively engage in governance can receive boosted rewards proportional to their staking and voting activity
3.
Similarly, in "Proof-of-Liquidity" models like Berachain's, a
Rewards Vault acts as a central pool where governance token holders (delegators) can increase reward emissions through their delegation, creating a self-sustaining cycle of liquidity and governance participation
