Educational profile of Dai (DAI) — not a buy, sell, peg guarantee, or price target. Read with the Maker (Sky) profile and size from a written invalidation, not from a category label. A listed ticker is not a thesis. Crypto-collateral dollar: vaults, PSM scars, and a Sky rebrand that did not delete the risk graph.
A Dollar With a Liquidation Engine
DAI is not Tether. It is not USDC. It is a token that is supposed to stay near a dollar because vaults over-post collateral, keepers liquidate, and (for years) a Peg Stability Module sat next to USDC. That last sentence is why purists fought and why DAI still worked in practice: it imported USDC risk to keep the peg. If you cannot say whether you are trading crypto-collateral DAI, PSM-adjacent DAI, or the Sky/USDS successor graph, you are guessing.
The problem Maker set out to solve is a dollar without a Tether. The problem they kept meeting is that a purely crypto-collateral dollar is pro-cyclical: ETH dumps, vaults get liquidated, DAI can trade rich or cheap depending on the flow, and users want an exit into something that feels like Circle. The PSM was the honest compromise. The Sky rebrand and USDS are the later political layer. DAI still exists as a ticker people hold. The risk graph under it did not get simpler.
1. MakerDAO, Black Thursday, PSM, Sky
MakerDAO went live in 2017 with Single-Collateral Dai, then Multi-Collateral Dai. Rune Christensen's project became the template for on-chain central banking: stability fees, liquidation ratios, keepers, and a governance token (MKR, later the Sky graph) that is supposed to recapitalize failure. That recapitalization is the equity-like risk. DAI holders care because a failed recap is a broken dollar.
Black Thursday in March 2020 — zero-bid auctions, network congestion, and under-water vaults — is the founding scar. Keepers and gas are part of the product. If Ethereum is too expensive or too broken to liquidate, DAI's machine is not a machine. It is a hope. Every later parameter change is a footnote to that weekend.
The PSM made DAI partly a wrapper of USDC. That was good for the peg and bad for the 'uncensorable dollar' pitch. Then RWA vaults brought Treasuries-shaped yield into the balance sheet. Then Sky and USDS tried to rename the graph. Traders who still model DAI as 'ETH-backed only' are using a 2018 spreadsheet. The founding constraint that still binds DAI is the peg depends on vault incentives, liquidations, and whatever the PSM-class pipes currently are. If you cannot say that without looking, you are trading a headline.
2. Vaults, keepers, oracles, modules
A vault posts collateral, mints DAI, and pays a stability fee. If the ratio breaks, keepers liquidate. Oracles tell the engine the collateral price. That means DAI inherits oracle risk, gas risk, and governance risk on every parameter. A 'decentralized stablecoin' is a lot of knobs. Knobs get turned.
DAI in Aave or a Curve pool is not the same object as DAI in your wallet. You have added protocol risk. DAI used as quote on a long-tail DEX can lose the peg locally while the Maker oracle is fine. Local pegs are real. Size the venue, not just the ticker.
Versus USDT/USDC, DAI can trade cheap when people want to delever and rich when people want to lever. Those basis moves are information about DeFi leverage, not about Circle's bank. Do not flatten all dollar tokens into one chart. Compare the failure mode to Aave profile rather than treating every Payments ticker as the same object.
3. DAI supply is a balance-sheet, not a meme float
DAI is minted and burned. Supply goes up when vaults want leverage or when PSM-class pipes ingest other dollars. That is not 'inflation' in the DOGE sense. It is the size of the Maker balance sheet. Read collateral mix and surplus buffer the way you would read a bank, not the way you would read an altcoin unlock calendar.
MKR/Sky is the recap and governance token. DAI is the liability. Mixing them because they share a dashboard is how people 'hedge' a dollar with a volatile governance coin and call it safety. If you want the dollar, size the dollar. If you want the equity, size the equity. Not both in one brain cell. Token design is not a reason to skip DAI explained.
4. How traders actually use DAI
DAI is not a savings account. DAI trades in DeFi as collateral, as a Curve asset, and as a refuge during CEX drama — until the drama is an ETH cascade. Then DAI is pro-cyclical. Know which week you are in. Name the object in one sentence: a dollar-shaped token minted against collateral and parameters a governance process can change.
Worked size (illustration only, not a recommendation): a $45,000 account risking $450 on DAI with invalidation $0.03 away from a $1 handle is about 15000 units of risk budget, not a round lot copied from a timeline. The object is a dollar-shaped token minted against collateral and parameters a governance process can change. The event you must survive is a liquidation cascade on ETH-class collateral while the PSM cannot absorb the flow. If that event would breach the dollar cap, you are already too large. Do the arithmetic in the position size tools the same way you would on a volatile L1, then write the invalidation before the click. Three cents is the polite stop. Black-Thursday-class events are not polite. If you cannot skip a cascade, cut units. A 1% account-risk rule is still a rule when the ticker is a dollar, a privacy coin, a GPU network, or a game token. The DeFi yield course exists so this sentence is a habit, not a mood. Dai will still be listed tomorrow. Your account might not be if you argue with the event. Conviction does not appear in the denominator. Neither does a logo, a peg slogan, or a roadmap slide. Educational only.
Uses: (1) DeFi inventory when you explicitly want non-Circle/non-Tether; (2) a basis trade versus USDC when PSM-class pipes are stressed; (3) vault leverage if you can survive the liquidation engine. Item 3 is how accounts die. Item 1 is still issuer-and-governance risk, just a different issuer.
5. Competitive set and what actually breaks
Liquity's LUSD, other CDP dollars, USDC, and USDT. DAI's edge was being first and being embedded. DAI's hole is complexity plus the political cost of RWA and rebrands. Embedded is not immortal. Relative views belong next to collateralized debt positions, not in a group chat.
What breaks DAI: oracle failure, liquidation failure, a governance attack or misconfig, a bad RWA, or a run that the surplus buffer cannot absorb. What does not: a 30-basis-point cheap print on a Sunday that keepers are already closing.
Payments tickers are credit stories wearing a dollar costume. Dai is no exception. The costume is a dollar-shaped token minted against collateral and parameters a governance process can change. The credit is the peg depends on vault incentives, liquidations, and whatever the PSM-class pipes currently are. When the costume and the credit diverge, DAI does not become 'crypto.' It becomes a queue: redemptions, attestations, issuer comments, and a secondary-market wick that teaches you whether you sized a cash-like instrument or a confidence instrument. DAI's 'decentralized dollar' story now sits next to real-world-asset vaults and a rebrand (Sky, USDS). Read the current collateral mix, not the 2019 blog. Velocity is not a moat. A faster settlement rail is not a reason to skip issuer risk. If you cannot name the redemption path in one sentence, you are holding a meme that happens to print $1.00 most days.
A peg is a market outcome, not a law. DAI can trade through $1.00 for hours and still be 'fine' in the issuer's FAQ. Your account does not live in the FAQ. Size so that a liquidation cascade on ETH-class collateral while the PSM cannot absorb the flow. is a boring week. A collateral crash plus slow liquidation, or a governance misconfig, reprints DAI as an unpegged IOU. Traders who treat every payments token as interchangeable will misread a week where one issuer's float is wanted and another's is offered. Those are different objects. Write the one you actually have.
6. Field notes the FAQ will not write
DAI on Ethereum L1 and DAI on an L2 are connected by a bridge. Bridged DAI has canonical-bridge risk. If the page you are reading says 'DAI' and does not say which, it is not a runbook.
Stability fees are not your yield. They are the cost of someone else's leverage. When fees jump, vaults delever and DAI basis moves. That is a flow, not a moral.
The surplus buffer is the shock absorber. If you cannot find the current buffer and the current collateral mix, you are not a DAI trader this week. You are a spectator.
USDS and DAI can coexist in wallets and dashboards. Migration risk is user-error risk: wrapping, unwrapping, and phishing sites that look like Sky. Slow down.
A DAI-USDC pool with tiny liquidity can depeg locally. Your 'dollar' is then a 200-basis-point object. Check depth, not just the ticker.
Governance attacks are rare and exist. Parameter changes are common and exist. Both can reprice DAI without a tweet from Circle. Watch the executive spells if you size this as more than inventory.
7. Mistakes, limits, takeaways
Mistakes: calling DAI 'decentralized cash' while it is full of USDC and RWAs; ignoring Sky/USDS migration; looping DAI in a farm and forgetting the vault on the other side; treating MKR burns as a reason DAI cannot depeg. Burns do not print dollars in a panic. For process, see DeFi risk guide.

Key Takeaways
- DAI is a CDP dollar with governance knobs, not a bank coin and not an algo coin.
- PSM and RWA history means DAI imported TradFi pipes on purpose.
- Keepers, gas, and oracles are the product.
- Do not mix DAI (liability) with MKR/Sky (equity).
- Education only. No recommendation.
Dai (DAI) can remain a useful tool in crypto and still be a poor risk-adjusted hold at the wrong size. Those sentences are allowed to be true together. Educational only. Not tax, legal, or a recommendation to buy, sell, or hold DAI. If this page and the primary docs disagree, the docs win. Maps go stale. DAI still trades.
Not financial advice. Not a recommendation to buy, sell, or hold DAI.
Dai (DAI) is a crypto instrument, not a listed equity. There is no 10-K. Read the protocol docs, the canonical contract, and the venue rulebook. If those disagree with this page, they win. Educational only. Not a recommendation to buy, sell, or hold DAI. Repeat the size math any time the object (a dollar-shaped token minted against collateral and parameters a governance process can change.) or the event (a liquidation cascade on ETH-class collateral while the PSM cannot absorb the flow.) changes. (Dai crypto note 1.)
Liquidity in DAI is not a thesis. It only means you can be wrong in size. The binding constraint is the peg depends on vault incentives, liquidations, and whatever the PSM-class pipes currently are. If you cannot paraphrase that constraint without looking, you are not ready to click. (Dai crypto note 2.)
The implied move around a liquidation cascade on ETH-class collateral while the PSM cannot absorb the flow. is a sizing input, not a dare. If that window is larger than you can sleep through, cut units until you can. Dai will still be listed. Your account might not be if you argue with the window. (Dai crypto note 3.)
A category label (Payments) is not a stop. Your stop is the price that falsifies this object: a dollar-shaped token minted against collateral and parameters a governance process can change. Write that sentence in the journal before the click. (Dai crypto note 4.)
Peer beta and sector tapes can drag DAI on a day that has nothing to do with Dai. That is not unfair. That is how factor exposure works. If you cannot tolerate it, you are too large, or you picked the wrong vehicle. (Dai crypto note 5.)
Failure mode to pre-accept: A collateral crash plus slow liquidation, or a governance misconfig, reprints DAI as an unpegged IOU. If that sentence would force a style drift into revenge adding, you do not have a process. You have a preference. (Dai crypto note 6.)
