Decentralized Autonomous Organizations (DAOs) like MakerDAO are redefining how value is generated and distributed in blockchain ecosystems. Unlike traditional corporations, they don’t publish quarterly earnings or balance sheets—yet financial activity is transparent, on-chain, and auditable. The challenge lies in interpreting this raw data to understand who truly benefits from the system’s success.
This analysis dives into MakerDAO’s income structure during its early phase—specifically 2018, when the Single-Collateral DAI (SCD) system was live. By examining revenue streams such as stability fees and liquidation penalties, we uncover how value flowed across different participant groups: MKR holders, PETH holders, keepers, and the broader ecosystem.
Understanding MakerDAO’s Revenue Streams
MakerDAO operates as a decentralized credit platform that enables users to generate DAI, a stablecoin soft-pegged to the US dollar, by locking up collateral—initially only ETH—in Collateralized Debt Positions (CDPs). Two primary mechanisms generate income for the protocol: stability fees and liquidation penalties.
These revenues are then redistributed across the network, but not equally. The distribution model reveals important insights about incentive alignment, efficiency, and long-term sustainability.
Stability Fees: The Core Income Source
Stability fees function as interest paid by CDP holders on their DAI debt. These fees were variable throughout 2018:
- Started at 0.5% in January
- Increased to 2.5% on August 30
- Reduced back to 0.5% on December 21
Two key metrics help analyze this income:
- Accrued stability fees: Interest accumulated over time within open CDPs.
- Collected stability fees: Fees actually paid when a CDP is closed or repaid.

Only collected fees contribute directly to protocol revenue. Notably, if a CDP is liquidated, any accrued but unpaid stability fee is forgiven—a design quirk of the SCD system intended to streamline liquidations but which reduces potential income for MKR holders.
In 2018, total collected stability fees amounted to approximately 183,000 DAI, used exclusively to purchase and burn MKR tokens. This deflationary mechanism benefits MKR holders by reducing supply, increasing scarcity.
Liquidation Penalties: A Hidden Revenue Engine
While less visible, liquidation penalties became a major income driver during 2018’s bear market. When a CDP’s collateral ratio falls below the required threshold (due to price drops), it becomes subject to liquidation.
At the time, a flat 13% penalty was applied during liquidation. This serves dual purposes:
- Discourage under-collateralization
- Offset operational inefficiencies in the liquidation process
Liquidations inject DAI into the system, creating temporary surpluses. In volatile markets—like late 2018—these events spiked, turning penalties into a significant revenue source.
The Role of Keepers and PETH Holders
To maintain system solvency, MakerDAO relies on automated actors called keepers—bots that monitor CDPs and execute liquidations when needed.
Here’s how the liquidation workflow functions:
- A CDP is "bitten" (liquidated), wiping its DAI debt in exchange for PETH collateral.
- Collateral moves to the Tap contract.
- Keepers receive a 3% discount on PETH purchases to incentivize fast action.
- After purchase, DAI is burned; surplus funds remain in the system.
Despite generating 4.25 million DAI in surplus from liquidations in 2018, inefficiencies eroded much of this gain:
- 1.58 million DAI in keeper incentives were paid out
- 251,000 DAI was lost due to collateral depreciation before sale
Crucially, liquidation profits were not shared with MKR holders. Instead, they were used to buy and burn PETH—the token representing ETH locked in the system.
Over the year, 21,591.48 PETH (worth ~4.13 million DAI) was burned, directly benefiting PETH holders through supply reduction.
Value Distribution: Who Truly Benefits?
When we map all income and redistribution flows from 2018, a clear pattern emerges:
Keepers and PETH holders captured the vast majority of value—far exceeding what MKR holders received.
| Group | Benefit Mechanism | Value Captured (DAI) |
|---|---|---|
| MKR Holders | Burned via stability fees | ~183,000 |
| PETH Holders | Burned via liquidation surplus | ~4.13 million |
| Keepers | Discounted PETH purchases | ~1.58 million |
This imbalance stems from structural design choices:
- Only collected stability fees benefit MKR holders
- Liquidation gains flow entirely to PETH holders
- Keeper incentives eat into protocol surplus
For investors expecting MKR to capture protocol value directly, this model presents a challenge. While MKR governs risk parameters and upgrades, it does not participate in liquidation upside under SCD.

Transition to Multi-Collateral DAI: A Game Changer
The launch of Multi-Collateral DAI (MCD) marked a pivotal shift in MakerDAO’s economic model:
- PETH was eliminated, merging all ETH-backed positions into a unified collateral pool
- MKR replaced PETH as the recipient of surplus auctions
- Liquidation penalties now primarily benefit MKR holders through direct buybacks and burns
However, this introduces new risks:
- If liquidations result in losses (due to price crashes or auction failures), MKR is diluted via minting
- Lower penalty rates may reduce keeper participation unless incentives are carefully tuned
Still, MCD aligns incentives more closely with long-term stakeholders. MKR holders now stand to gain from both stability fees and profitable liquidations—making MKR a more compelling governance and value-capture asset.
Frequently Asked Questions
Why didn't MKR holders benefit more from liquidations in 2018?
Under Single-Collateral DAI, liquidation surpluses were redirected to PETH holders via buy-and-burn mechanisms. MKR only benefited from stability fees collected upon CDP closure.
What happened to PETH after MCD launched?
PETH was deprecated and replaced with WETH (Wrapped ETH) as collateral in the new system. Users could exchange PETH for WETH at a pro-rata rate before the migration deadline.
How does burning MKR affect its value?
Burning reduces total supply, increasing scarcity. If demand remains constant or grows, this deflationary pressure can support price appreciation over time.
Are keepers still necessary in MCD?
Yes, keepers continue to play a critical role in monitoring CDPs and initiating liquidations. However, improved auction mechanics have reduced their profit margins and increased efficiency.
Is MakerDAO profitable today?
Yes—under MCD, Maker consistently generates surplus revenue from stability fees and liquidations, which is either used to buy and burn MKR or added to protocol-owned liquidity reserves.
Does volatility hurt MakerDAO?
Short-term volatility increases liquidation events and keeper costs. However, strong risk management and over-collateralization protect solvency. Long-term growth depends on adoption and diversified collateral.

Final Thoughts: Patience Rewarded in Decentralized Finance
MakerDAO set a benchmark for sustainable DAO economics. Its early model prioritized stability over immediate returns for MKR holders—a deliberate trade-off that ensured DAI’s resilience during turbulent markets.
While initial value capture favored early adopters (PETH holders) and service providers (keepers), the evolution to MCD has rebalanced incentives toward long-term governance stakeholders.
For investors, this underscores an essential truth: in DeFi, patience often beats speculation. MakerDAO’s journey reflects a maturing ecosystem where robust design triumphs over short-term gains.
As decentralized finance evolves, protocols that align incentives, ensure transparency, and adapt dynamically will lead the next wave of innovation—and value creation.
