What Is MakerDAO: Complete Decentralized Lending Protocol Guide (2026)

What is MakerDAO? Complete 2026 guide: vault mechanics, DAI/USDS peg, Endgame Plan, MKR->SKY migration, SubDAOs (Spark) and tokenized US Treasuries collateral.

MakerDAO is the original decentralized lending protocol that proved DeFi could actually work at scale. Launched in 2017, it created DAI, the first truly decentralized stablecoin, and pioneered the overcollateralized lending model that every major Aave, Compound, and Liquity protocol would later copy. Nearly nine years later, it is still the largest crypto-native lending system in existence, and in 2026 it sits at the center of one of the most ambitious restructurings in DeFi history.

While most DeFi projects from 2017 have either died, been rebuilt from scratch, or shrunk into irrelevance, MakerDAO has done the opposite. It has scaled to over $10 billion in total value locked, rebranded itself into the Sky ecosystem, launched a new stablecoin called USDS, migrated its governance token from MKR to SKY, integrated billions of dollars in tokenized US Treasuries, and spun off a constellation of SubDAOs led by Spark Protocol. This is no longer a single application. It is a federation of DeFi protocols sharing the same liquidity backbone.

This guide explains exactly what MakerDAO is in 2026: how the original vault mechanism still works, how the peg holds, what the Endgame Plan actually means in practice, how the MKR to SKY migration affected token holders, and why some of the world's largest asset managers are now using MakerDAO infrastructure to bring real-world assets on-chain. By the end you will understand both the historical foundation of the protocol and the very modern reality it operates in today.

What Is MakerDAO?

MakerDAO is a decentralized lending protocol built on Ethereum that allows users to deposit crypto collateral and mint a stablecoin against it. The protocol was founded by Rune Christensen in 2014, with the first version of the system going live in December 2017. That first version was called Single-Collateral DAI, or SAI, and it accepted only ETH as collateral. In November 2019, the protocol upgraded to Multi-Collateral DAI (MCD), which is the architecture still used today. MCD allowed the protocol to accept dozens of different collateral types, each with its own risk parameters, stability fees, and debt ceilings.

At its core, MakerDAO is a credit facility implemented in smart contracts. You deposit collateral worth more than what you want to borrow, the protocol mints new stablecoins and gives them to you, and you can repay the debt at any time to unlock your collateral. There is no human counterparty, no bank, and no credit check. Everything is enforced by code. The MakerDAO governance system, originally controlled by holders of the MKR token, sets the rules: which collateral types are accepted, what loan-to-value ratios are allowed, what interest rate to charge, and what to do when something goes wrong.

In 2024, MakerDAO began executing the Endgame Plan, a multi-year restructuring proposed by Rune Christensen. The plan introduced a new brand called Sky, a new stablecoin called USDS that runs in parallel to DAI, a new governance token called SKY, and a set of semi-autonomous SubDAOs that handle specialized functions. By 2026 both DAI and USDS are still in circulation, both MKR and SKY are still valid governance tokens, and the two systems coexist while the migration continues. This is the snapshot we will work from in the rest of this guide.

The Vault Mechanism

The unit of borrowing in MakerDAO is the vault. In the original SAI system these were called CDPs, or Collateralized Debt Positions. In MCD they were rebranded to vaults but the concept is identical. A vault is a smart contract that holds your collateral and lets you mint stablecoins against it up to a limit defined by the collateral type's liquidation ratio.

Suppose you want to mint DAI using ETH as collateral. You first open a new ETH-A vault. The "A" suffix refers to a specific risk profile (there are also ETH-B, ETH-C, and so on with different parameters). You deposit ETH into the vault. The protocol now lets you mint DAI up to a certain percentage of your collateral value. If the liquidation ratio for ETH-A is 145%, that means you must keep at least $145 of ETH locked for every $100 of DAI you mint. If your ETH falls in value and your collateralization ratio drops below 145%, your vault becomes liquidatable, and any keeper bot on the network can trigger an auction to sell your collateral and repay your debt.

Whenever you have an open vault, the protocol charges you an annualized interest rate called the stability fee. This fee is denominated in DAI (or USDS) and accrues continuously to your debt balance. When you close the vault, you must repay the original DAI minted plus all accrued stability fees. Different collateral types have different stability fees: highly liquid assets like ETH typically charge 5-10% per year, while more exotic or volatile collaterals can charge much more.

Worked Example: A Real ETH-A Vault

Let us walk through concrete numbers. Suppose ETH trades at $4,000 and you deposit 5 ETH into an ETH-A vault. Your collateral is worth $20,000. The ETH-A liquidation ratio is 145% and the stability fee is 7% annualized. You mint 10,000 DAI. Your collateralization ratio is $20,000 divided by $10,000, which equals 200%. You are comfortably above the 145% liquidation threshold. Now you take that 10,000 DAI and use it elsewhere: maybe to farm yield, maybe to buy more ETH for a leveraged long, maybe to pay rent in stablecoins without selling your ETH.

Six months later, you want to close the vault. ETH has dropped to $3,200. Your collateral is now worth $16,000. Your collateralization ratio is $16,000 divided by $10,000, which equals 160%. Still safe, but uncomfortably close to the 145% liquidation level. The 7% stability fee has accrued for half a year, so you owe $10,000 plus roughly $350 in interest, for a total debt of $10,350. You buy 10,350 DAI on the market, send it to the vault to burn it, and the protocol releases your 5 ETH. Your net result is that you got six months of liquid stablecoin exposure without selling any ETH, at a cost of $350 plus whatever gas you paid.

DAI and USDS Stability: How the Peg Holds

The whole value proposition of MakerDAO depends on DAI and USDS staying near $1. There are four primary mechanisms the protocol uses to defend the peg.

The first is the Peg Stability Module, or PSM. The PSM lets users swap USDC, USDP, or other approved fiat-backed stablecoins for DAI at a 1:1 ratio with a near-zero fee. If DAI falls below $1, arbitrageurs buy cheap DAI on the open market and redeem it for USDC at $1 through the PSM, capturing the spread and pushing DAI back up. If DAI rises above $1, arbitrageurs deposit USDC and mint DAI at $1, then sell it on the market above peg. The PSM is fast, efficient, and the dominant peg defense mechanism in normal market conditions.

The second mechanism is the Dai Savings Rate (DSR) and its newer cousin the Sky Savings Rate (SSR). DSR is a contract where DAI holders can lock their tokens and earn yield paid out by the protocol. If DAI is trading below peg, governance can raise the DSR to incentivize holders to lock up DAI, reducing circulating supply and pushing the price back up. If DAI is above peg, governance can lower the DSR. In 2026 the SSR for USDS often hovers between 5% and 8%, funded primarily by yield from RWA collateral.

The third mechanism is the surplus auction. When stability fee revenue exceeds the protocol's losses, the excess accumulates in the Maker Buffer. Once the buffer hits a threshold, the protocol uses the surplus to buy back and burn MKR or SKY tokens, reducing token supply. The fourth mechanism is the debt auction. If the protocol ever has more debt than collateral (the system becomes undercollateralized), it mints new MKR/SKY and auctions it for DAI to recapitalize. This is why MKR holders are called the "liquidator of last resort": their token gets diluted if the system fails.

The MKR Token: Original Governance Plus Liquidator of Last Resort

The MKR token has played two roles since 2017. First, it is the governance token. MKR holders vote on every parameter in the protocol: which collateral types to accept, what their stability fees should be, what their debt ceilings are, what the DSR is set to, and whether to onboard new modules. Each MKR token equals one vote. This makes MakerDAO governance unusually high-stakes for a DAO: a single bad parameter change can drain millions from the protocol.

Second, MKR is the backstop. If the system becomes undercollateralized (which happened during Black Thursday in March 2020, as we will discuss later), the protocol mints new MKR out of thin air and auctions it to recapitalize. This inflates the MKR supply and dilutes existing holders. In normal times, the opposite happens: the protocol uses surplus revenue to buy MKR off the market and burn it, making each remaining MKR more valuable. From 2019 to 2024, MKR was net deflationary across most periods, which contributed to its strong price performance.

MKR tokenomics were intentionally simple: there were 1,000,000 MKR at genesis, no team allocation with formal token vesting in the modern sense (the founding team simply held tokens), and supply changes only through the surplus/debt auction mechanism. By 2024, MKR supply had fallen to around 880,000 tokens through years of buybacks. This is the token that, in August 2024, started its migration to SKY.

The Endgame Plan

The Endgame Plan was first proposed by Rune Christensen in 2022 and approved by MKR governance in 2023. It is the most ambitious restructuring any major DeFi protocol has ever attempted. The plan recognized that MakerDAO had grown too complex to be governed by a single monolithic DAO. Decisions about RWA onboarding, smart contract upgrades, marketing, and growth all flowed through the same governance vote. This created bottlenecks, governance fatigue among MKR voters, and political infighting.

The solution was to break MakerDAO into a core layer plus a constellation of SubDAOs. The core layer (now called Sky) handles the fundamental stablecoin, the collateral risk parameters, and the protocol-wide treasury. Each SubDAO handles a specific domain: lending markets, RWA allocations, ecosystem grants, governance facilitation. Each SubDAO has its own token, its own treasury, and its own governance, while remaining contractually tied to the core layer. The result is a federation, not a monolith.

MKR to SKY and DAI to USDS Migration

The migration was officially launched on August 27, 2024. On that date, two new tokens went live: USDS as a parallel stablecoin to DAI, and SKY as a parallel governance token to MKR. The migration is voluntary and one-way: holders can convert MKR to SKY at a fixed ratio of 1 MKR = 24,000 SKY, and DAI to USDS at a 1:1 ratio. There is no deadline to migrate. The protocol officially supports both pairs of tokens indefinitely, although various incentives push users toward the new versions.

Why migrate at all? Two reasons. First, USDS has features that DAI does not. USDS holders can stake into the Sky Savings Rate contract to earn yield. USDS also has a Freeze Function under certain regulatory scenarios, which is controversial among DeFi purists but makes USDS more palatable to institutional partners. DAI remains permissionless and unfreezable, so users who care about that property keep their DAI.

Second, SKY has new tokenomics that MKR did not. The conversion ratio of 1:24,000 was designed to make SKY a "retail-friendly" denomination so that 1 SKY trades around the $1 to $5 range rather than MKR's historical $1,000-plus price. SKY also introduces farm rewards: SKY tokens can be staked to earn USDS or to earn the governance tokens of various SubDAOs. This creates a richer incentive structure than MKR ever had. The downside of SKY is that, unlike MKR's hard cap, SKY supply can be expanded by governance under certain conditions, which is a less hardline monetary policy.

GOVERNANCE TOKEN
MKR ➔ SKY
1 MKR converts to 24,000 SKY. Voluntary migration with no deadline. Both tokens retain voting rights on Sky core protocol.
STABLECOIN
DAI ➔ USDS
1 DAI converts to 1 USDS at any time. USDS earns Sky Savings Rate. DAI remains permissionless.

As of early 2026, roughly 35% of MKR supply has been migrated to SKY, and roughly 45% of DAI supply has been migrated to USDS. The migration is faster on the stablecoin side because users care more about yield than about voting rights. Most DeFi protocols now accept both DAI and USDS interchangeably, and many lending markets quote yields in USDS terms because the SSR creates a natural floor on USDS-denominated returns.

The Five SubDAOs

The Endgame Plan organized the ecosystem around a small set of SubDAOs. As of 2026, five are operational. Each has its own focus, its own token, and its own treasury, but all share the Sky core layer underneath.

Spark Protocol is the lending market SubDAO. It runs an Aave V3 fork that uses USDS as its primary borrowing asset. When you borrow USDS on Spark, you are effectively borrowing from a USDS line of credit that the core protocol extends to Spark directly through a module called the D3M (Direct Deposit Module). This means USDS borrowing rates on Spark can be set algorithmically and remain extremely competitive. Spark has its own governance token, SPK, distributed to early users.

AllocatorDAO handles capital allocation. When the core protocol wants to deploy USDS into yield-generating positions (most often RWA strategies like tokenized Treasuries), AllocatorDAO manages the relationship with the off-chain counterparty. This decouples the slow legal work of onboarding a tokenized fund from the fast governance cycle of the core protocol.

Facilitator SubDAOs run the operational machinery of governance: maintaining voting infrastructure, paying delegates, coordinating polls, and producing the documentation that voters rely on. NewLabs is the R&D SubDAO, working on new products including a dedicated L2 chain code-named NewChain that will host future Sky ecosystem applications. Allocator SubDAOs operate at a higher level than AllocatorDAO and decide on the overall split of USDS reserves across SubDAOs, RWA partners, and DeFi protocols.

Collateral Types in 2026

The composition of MakerDAO's collateral backing has shifted dramatically since the early days. In 2019, almost all DAI was backed by ETH. By 2022, USDC dominated the backing through the PSM. By 2026, real-world assets have become the single largest collateral category, reflecting the Endgame Plan's push toward yield-generating assets.

USDS/DAI COLLATERAL COMPOSITION (ILLUSTRATIVE 2026)
RWA Treasuries
40%
ETH and wstETH
35%
USDC PSM
15%
Other LSTs/LRTs
10%
Composition shifts continuously based on governance decisions. RWA dominance reflects Endgame Plan strategy.

The "RWA Treasuries" slice consists primarily of tokenized US Treasury bills held by off-chain partners. The "ETH and wstETH" slice is the classic crypto collateral, with wstETH (Lido staked ETH) being the most popular flavor because it earns staking yield in addition to backing DAI. The "USDC PSM" slice is the operational peg-defense buffer. The "Other LSTs/LRTs" slice covers liquid staking tokens beyond wstETH such as rETH, cbETH, and various liquid restaking tokens. Governance can adjust these ratios at any time.

RWA Collateral: Tokenized US Treasuries

The integration of real-world assets into MakerDAO began modestly in 2020 with a small loan to a New Jersey real estate fund. It exploded in 2023 and 2024 when MakerDAO began allocating billions of dollars in DAI reserves into short-duration US Treasury bills through partners like Monetalis (Clydesdale vault), BlockTower Capital, and various tokenized money market funds.

The mechanism works like this. The MakerDAO core protocol deposits USDC (acquired through the PSM) with a regulated off-chain partner. The partner uses that USDC to buy US Treasury bills through traditional brokerage rails. The Treasuries are held in custody, and a tokenized representation is issued on-chain back to MakerDAO. The yield from the Treasuries (typically 4-5% per year at current rates) flows back to the protocol. This yield is what funds the Dai Savings Rate and the Sky Savings Rate at competitive levels. Without RWA yield, the SSR could not sustain 5-8%; it would have to fall back to whatever stability fee revenue and Spark interest could support, which would be much less.

The RWA strategy is also the most controversial part of MakerDAO's evolution. Purists argue that it reintroduces centralized counterparty risk: if Monetalis or BlockTower were to be seized, frozen, or forced to violate the agreement, the protocol could lose hundreds of millions. Defenders argue that the risk is mitigated by diversification across multiple counterparties and by the structural overcollateralization of the system. The 2024 governance battle (discussed below) was largely about this tradeoff.

Spark Protocol: The Yield-Bearing Lending Arm

Spark Protocol is functionally MakerDAO's answer to Aave. It is a separate lending market with its own governance and its own token (SPK), but it is tightly integrated with the core protocol through the D3M. Users deposit collateral on Spark (ETH, wstETH, sUSDS, and so on) and borrow USDS or other supported assets against it.

What makes Spark unique is the D3M. The Direct Deposit Module lets the MakerDAO core protocol mint USDS directly into Spark's liquidity pool whenever Spark's utilization rate exceeds a target. This means Spark almost always has cheap USDS to lend, because the supply is effectively unlimited and price-controlled by the core protocol rather than by depositor competition. As a result, USDS borrowing rates on Spark tend to be 1-3% lower than equivalent USDC borrowing rates on Aave, which makes Spark very attractive for leveraged stablecoin strategies and for yield farming setups.

Spark also offers sUSDS, a staked version of USDS that earns the Sky Savings Rate automatically. You deposit USDS, receive sUSDS at a 1:1 ratio initially, and the sUSDS slowly grows in redeemable value as yield accrues. sUSDS can then be used as collateral elsewhere in DeFi, creating elegant compounding strategies that did not exist with plain DAI.

The Dai Savings Rate (DSR) and Sky Savings Rate (SSR)

The DSR has been part of MakerDAO since the launch of Multi-Collateral DAI in November 2019. Originally it was a passive monetary policy tool used to nudge the DAI peg up or down. By 2023, it had become a major yield product in its own right, with MakerDAO paying out hundreds of millions of DAI per year to DSR depositors. The peak rate was 8% briefly in 2023, drawing in over 1.5 billion DAI of deposits.

The SSR is the USDS-denominated equivalent. The rates are typically similar but not identical: SSR is sometimes set slightly higher to incentivize the migration from DAI to USDS. As of 2026 both rates float between 5% and 8% depending on Treasury yields and governance decisions. Anyone can deposit DAI to the DSR contract or USDS to the SSR contract and start earning immediately. There is no minimum amount, no lock-up, and no withdrawal fee. The rates are paid in the same currency you deposited, and there is no flash loan or smart contract loop required to access them: they are first-class features of the protocol.

Historical Crisis Moments

MakerDAO has survived two near-death experiences. Understanding them is essential context for why the protocol is structured the way it is today.

Black Thursday, March 12, 2020

On March 12, 2020, the ETH price crashed from roughly $200 to under $90 within 24 hours as global markets panicked over the early COVID-19 pandemic. Ethereum mainnet became congested. Gas prices spiked to hundreds of gwei. MakerDAO vaults across the system fell below their liquidation ratios simultaneously, and the protocol started auctioning collateral to recapitalize.

The problem was that the keeper bots that participated in auctions could not get their transactions confirmed because gas prices were unpredictable. Some bots got transactions through with zero-bid auctions because no one was competing. The result was that approximately $8 million of ETH was sold for 0 DAI to a handful of opportunistic bidders. The protocol ended up roughly $4 million undercollateralized.

To recapitalize, MakerDAO triggered the first-ever debt auction. The protocol minted new MKR tokens and auctioned them for DAI to refill the buffer. MKR holders were diluted, and the price of MKR fell sharply. This was the moment when the "liquidator of last resort" mechanism was tested for real. It worked, but it was painful. The lessons learned: better auction mechanisms (Liquidations 2.0, deployed in 2021), more conservative liquidation ratios, and a much larger surplus buffer to absorb future shocks.

The 2024 Endgame Governance Battle

The Endgame Plan was not universally popular. From late 2023 through mid-2024, the MakerDAO governance forum hosted heated debates about whether the rebrand to Sky, the introduction of USDS with its potential freeze function, and the deepening RWA exposure were the right strategic moves. Several long-standing delegates publicly opposed the plan. Major DAOs and DeFi protocols that integrated DAI (including Aave and Curve) initially refused to add USDS support, citing concerns about the freeze function.

The vote ultimately passed, but the social fabric of MakerDAO was strained. Some founding-era contributors left. The protocol's reputation as an apolitical neutral infrastructure took a hit. By 2026 most of the dust has settled: USDS is widely supported, the freeze function has never been used, and the protocol is materially larger and more profitable than it was pre-Endgame. But the episode is a useful reminder that even mature DeFi protocols can have wrenching governance fights.

How to Open a Maker Vault Step-by-Step

Opening a vault used to require directly interacting with the MakerDAO contracts, which was technical and intimidating. Today, the standard interface is Oasis.app (now rebranded to Summer.fi) or the official Sky.money portal. Both abstract away the smart contract complexity into a clean UI.

Step 1: Connect your wallet. Visit summer.fi or app.sky.money and connect MetaMask, Rabby, or any standard Ethereum wallet. Make sure you have ETH (or whatever asset you plan to use as collateral) plus a small ETH balance for gas.

Step 2: Choose the vault type. Pick the "ilk" you want to use. ETH-A is the conservative ETH vault with a 145% liquidation ratio. ETH-B is a higher-leverage variant with a 130% ratio (and a higher stability fee to compensate for the additional risk). wstETH-A lets you use Lido staked ETH and earn the staking yield while borrowing against it. Pick based on your risk appetite.

Step 3: Set your deposit and mint amounts. The UI will show you your projected collateralization ratio and liquidation price in real time. A common rule of thumb is to aim for at least a 200% collateralization ratio on ETH-A, giving you a buffer against price drops. Anything below 165% is uncomfortably close to liquidation for a volatile asset like ETH.

Step 4: Sign the transactions. You will typically sign two transactions: one to approve the collateral token (if not already approved), and one to open the vault and mint DAI/USDS. Both happen in the same UI flow. Gas costs at typical Ethereum mainnet rates run between $5 and $30 depending on network congestion.

Step 5: Monitor and manage. After opening, you can deposit more collateral, withdraw collateral, mint more DAI, or repay debt at any time through the same interface. Most users also set up liquidation protection through Summer.fi's Automation feature, which can automatically repay debt or add collateral when your ratio approaches the danger zone.

Governance: How MKR and SKY Holders Vote

MakerDAO governance happens on two layers. The first is informal: discussions on the forum (forum.makerdao.com and forum.sky.money), proposals from delegates, signal polls to gauge sentiment, and Risk Working Group reports. The second is on-chain: continuous approval voting (CAV) where MKR and SKY holders can move their voting weight between candidate proposals at any time. Whichever proposal has the most votes is the active winner. This system is unusual because there is no fixed voting deadline; votes can shift in real time.

The largest blocks of voting weight are held by delegates, who are individuals or organizations that other MKR/SKY holders have entrusted with their votes. Delegates publish their voting rationale on the forum and are paid stipends by the protocol for their work. This is one of the few governance systems in DeFi that has a functioning professional class of governance participants. The downside is that voter concentration is high: a small number of delegates control most of the votes, which means the system can be slow to change direction when those delegates disagree with the broader community.

Notable governance powers include: setting stability fees for every collateral type, raising or lowering the DSR and SSR, onboarding or offboarding collateral types, approving RWA counterparties, voting on smart contract upgrades, and triggering the Emergency Shutdown if catastrophic conditions arise. Emergency Shutdown is a nuclear option: it freezes the entire protocol, returns collateral to vault owners in proportion to their debt, and effectively unwinds the system. It has never been triggered.

MakerDAO vs Aave vs Curve

It is helpful to position MakerDAO against the other two pillars of DeFi to understand what makes it unique. Aave is a money market: depositors lend their assets to a shared pool, borrowers borrow from that pool, and interest rates float based on utilization. Aave does not issue its own stablecoin in any meaningful sense (GHO exists but is small). MakerDAO is fundamentally different: depositors do not lend their assets to anyone, they lock collateral and mint new units of a stablecoin out of thin air. The stablecoin is the loan.

Curve is an automated market maker specialized in stablecoin and pegged-asset trading. Curve does not issue stablecoins (other than its experimental crvUSD), it facilitates trading between them. DAI and USDS are heavily traded on Curve pools, and the depth of those pools is critical to peg stability. Curve and MakerDAO are complementary: MakerDAO issues the stablecoin, Curve provides the secondary market for it.

The mental model is: MakerDAO is the central bank issuing the currency, Aave is the commercial bank lending the currency, Curve is the foreign exchange market trading the currency. All three are necessary for the stablecoin ecosystem to function, and they have coexisted for years without one displacing the others.

Frequently Asked Questions

What is the difference between DAI and USDS?

DAI is the original MakerDAO stablecoin launched in 2017 (Single-Collateral) and 2019 (Multi-Collateral). It is fully permissionless: there is no entity that can freeze your DAI or block you from using it. USDS is the new stablecoin launched in August 2024 as part of the Endgame Plan. It is convertible 1:1 with DAI in both directions. The key differences are that USDS holders can stake into the Sky Savings Rate to earn yield natively, and USDS includes a Freeze Function that governance could potentially activate under certain regulatory scenarios. Both tokens are issued by the same underlying protocol and are backed by the same collateral pool.

Is MakerDAO safe?

MakerDAO is one of the most battle-tested DeFi protocols in existence. Its core vault contracts have not had a critical exploit in over six years of operation, and they have processed hundreds of billions in cumulative volume. That said, there are real risks. Smart contract risk exists for every protocol. Oracle risk could cause incorrect liquidations during extreme volatility, as Black Thursday demonstrated. RWA counterparty risk has grown as the protocol increased its real-world exposure: if a regulated counterparty failed or was seized, hundreds of millions could be at risk. Governance risk is the most underappreciated: a malicious or careless governance decision could damage the system in ways that smart contracts alone cannot prevent.

How does MakerDAO make money?

The protocol earns revenue from three primary sources. First, stability fees: every vault pays an annualized interest rate on its debt, and this revenue flows to the protocol. Second, PSM swap fees: while small per transaction, the volume is enormous. Third, RWA yield: tokenized Treasury bills currently held in the collateral pool generate 4-5% per year on hundreds of millions of dollars. Spark also contributes revenue through the spread between the D3M USDS rate and the protocol's cost of capital. Net annual protocol revenue has consistently exceeded $100 million since 2023, which funds DSR/SSR payments, MKR/SKY buybacks, and SubDAO operations.

Can I lose my collateral in a Maker vault?

Yes. If your collateralization ratio falls below the liquidation ratio for your vault type, the protocol will trigger a liquidation. Keeper bots will then bid for your collateral in an auction. You will lose enough collateral to cover your debt plus a liquidation penalty (typically 13%) plus any auction inefficiency. In the worst cases (rapid price crashes plus auction failures, like Black Thursday), you can lose substantially more than the liquidation penalty would suggest. The safe practice is to maintain a comfortable buffer above the minimum ratio, monitor your position actively, and consider automated liquidation protection tools.

What is the Maker Endgame?

The Endgame Plan is the multi-year restructuring of MakerDAO into the Sky ecosystem, approved by MKR governance in 2023 and launched in August 2024. It involves the new USDS stablecoin, the new SKY governance token, and the breakup of monolithic governance into core-plus-SubDAO federalism. The longer-term goals include launching a dedicated L2 chain (NewChain), expanding RWA collateral to make USDS one of the world's largest yield-bearing stablecoins, and reducing governance complexity by distributing decision-making across specialized SubDAOs.

Should I migrate MKR to SKY?

This is a personal decision. The conversion rate is fixed at 1 MKR = 24,000 SKY and is reversible only through market trades (the official upgrade contract is one-way). Reasons to migrate: SKY has richer staking and incentive programs, SKY is the focus of future ecosystem development, some governance proposals are now SKY-only. Reasons not to migrate: MKR has a hard cap and historically stronger monetary policy, MKR remains a fully valid governance token, and you can keep MKR indefinitely with no penalty. As of 2026, both tokens coexist comfortably and you can wait as long as you want before deciding.

Conclusion

MakerDAO is the closest thing DeFi has to an institution. It is older than nearly every protocol it competes with, it survived Black Thursday and the governance battles of 2024, and it has scaled into something far larger than any single founding team could have anticipated. The Endgame Plan, USDS, SKY, the SubDAO federation, and the deep integration of tokenized US Treasuries make MakerDAO a fundamentally different protocol than it was even three years ago. But the core idea, originally articulated in 2014, is unchanged: a decentralized, overcollateralized credit facility that issues a soft-pegged stablecoin governed by token holders.

Whether you are using DAI or USDS as a savings instrument, opening a vault to access leveraged exposure on ETH without selling, earning yield through the SSR, borrowing USDS through Spark, or simply trying to understand how DeFi at its scale actually works, MakerDAO sits at the foundation. Every other protocol in the ecosystem either depends on Maker's stablecoin, competes with it, or builds on top of it. Understanding how Maker works is, in a real sense, understanding how DeFi works.

The next decade will test whether the Endgame federation can scale further without breaking, whether USDS can grow into a serious challenger to USDC and USDT on neutral grounds, and whether RWA integration ends up being a strategic masterstroke or a structural vulnerability. Either way, MakerDAO will continue to be one of the most interesting experiments in decentralized financial infrastructure ever attempted, and watching it evolve is one of the most informative ways to learn how on-chain finance grows up.
