Introduction
KeeperDAO (later rebranded to Rook) is a decentralized protocol built on Ethereum that addresses one of DeFi's most persistent problems: Maximal Extractable Value (MEV). MEV refers to the profit that bots or miners can extract by reordering, inserting, or censoring transactions — often at the expense of regular users.
Rather than letting MEV leak out of the system, KeeperDAO captures it cooperatively and redistributes it back to participants.
History & Background
KeeperDAO was first announced in 2019 and later launched its native governance token, ROOK, in 2020. The project describes itself as an economic experiment — an on-chain liquidity underwriter for DeFi.
Over time, the protocol evolved its product suite and eventually rebranded its public identity to 'Rook,' reflecting its broader vision as an open settlement protocol for DeFi.
How KeeperDAO Works
At the heart of the protocol are two key participant types: liquidity providers and keepers.
- Liquidity providers supply assets to shared pools. KeeperDAO abstracts away the complexity of running liquidation and arbitrage strategies, letting them earn a share of profits.
- Keepers are algorithmic agents that execute MEV opportunities — such as arbitrage and liquidations — using the pooled liquidity.
The Hiding Game is a central innovation. It works by encrypting user orders so they can only be executed by whitelisted Keepers. This protects users from front-running, eliminates gas costs on filled orders, and minimizes slippage. When a filled order generates MEV, the captured value is returned to the user as ROOK rewards.
Tokenomics
ROOK is the native governance token of the KeeperDAO ecosystem. Token holders can propose and vote on all protocol upgrades, administer profit-sharing parameters between liquidity providers and keepers, and adjust system-level settings.
ROOK emissions follow a decaying schedule — each quarter emits approximately 70% of the previous quarter's total, creating a gradually decreasing inflation rate. Governance retains the power to alter this decay. The distribution of newly emitted ROOK is also governed by the community, with allocations shifting over time between liquidity providers, keepers, and traders.
The design intentionally discourages passive holding: the end goal is to reward active participation in MEV mechanisms over simply holding the token.

Ecosystem & Use Cases
ROOK serves multiple roles within the protocol:
- Governance: Voting on upgrades, fees, and distribution strategies
- Incentives: Rewarding keepers, liquidity providers, and Hiding Game participants
- MEV rebates: Returned to traders whose orders generate extractable value
KeeperDAO's technology integrates with decentralized exchanges and lending protocols, supporting liquidations and limit order execution across the DeFi landscape.
Team, Governance & Community
KeeperDAO operates with a gradual decentralization approach. Early governance decisions were made by the core team, with the long-term goal of transferring full control to ROOK token holders via on-chain governance.
Community members engage through forums, Discord, Twitter, and Medium. Governance covers everything from fee parameters and contract upgrades to emission curves and new integrations.
Advantages
- MEV protection: Users benefit from encrypted order flow that prevents front-running
- Profit redistribution: Captured MEV is returned to protocol participants rather than lost to bots
- Gas-free fills: Orders executed through the Hiding Game incur no gas cost for users
- Cooperative model: Keepers and liquidity providers are aligned through shared incentives
- Community governance: ROOK holders have real control over protocol parameters
Risks & Challenges
- Smart contract risk: DeFi protocols carry inherent vulnerability to bugs or exploits
- Low activity: Trading volume and ecosystem activity have declined significantly since peak
- Keeper competition: The protocol's effectiveness depends on attracting and retaining high-quality keepers
- Regulatory uncertainty: DeFi protocols face evolving and unpredictable regulatory environments
- Governance participation: Low voter turnout can concentrate decision-making power
Long-Term Vision
KeeperDAO's long-term vision is to become a fully community-governed settlement layer for DeFi — one where MEV is no longer a tax on users, but a resource that flows back into the ecosystem. The protocol aims to expand its suite of MEV-aware tools, deepen integrations across DeFi, and refine its governance framework so that ROOK holders collectively steer the protocol's future direction.
Frequently Asked Questions
- What is KeeperDAO?
KeeperDAO is a DeFi protocol on Ethereum that coordinates 'keepers' — algorithmic bots — to capture MEV from liquidations and arbitrage, then redistributes those profits back to participants. It also offers MEV-protected order execution for regular traders.
- What is MEV and why does it matter?
MEV stands for Maximal Extractable Value — the profit bots or validators can extract by manipulating transaction order. KeeperDAO addresses this by capturing MEV cooperatively and returning it to users instead of letting it be siphoned away.
- What is the Hiding Game?
The Hiding Game is KeeperDAO's core product that encrypts user orders so only whitelisted Keepers can execute them. This prevents front-running and ensures users receive MEV rebates in ROOK when their orders generate extractable value.
- What is the ROOK token used for?
ROOK is the governance token of KeeperDAO, allowing holders to propose and vote on protocol upgrades, fee parameters, and emission schedules. It is also distributed as rewards to keepers, liquidity providers, and Hiding Game participants.
- How are ROOK tokens distributed?
ROOK tokens are emitted on a per-block basis following a decaying schedule, where each quarter emits roughly 70% of the previous quarter's amount. Governance controls how emissions are split between liquidity providers, keepers, and traders.
- Who are 'Keepers' in KeeperDAO?
Keepers are algorithmic agents that execute MEV opportunities — like arbitrage and liquidations — using the protocol's pooled liquidity. They are incentivized with ROOK rewards and a share of the profits they generate.
- Is KeeperDAO the same as Rook?
Yes. KeeperDAO later rebranded its public-facing identity to 'Rook,' though the underlying protocol and ROOK token remained the same. The Ethereum contract address and token symbol were unchanged by the rebrand.
- What are the risks of using KeeperDAO?
Key risks include smart contract vulnerabilities, declining ecosystem activity, dependence on active keeper participation, and the broader regulatory uncertainty facing DeFi protocols. Users should research thoroughly before engaging with the protocol.
