Dai (DAI) is one of the most established crypto-collateral-backed stablecoins. It is designed to track one US dollar while staying on-chain and permissionless at the protocol level. That design goal remains the same in 2026, but the ecosystem around DAI has evolved.
Most notably, Maker’s ecosystem has been rebranded as Sky Protocol, and DAI can be “upgraded” to USDS through an official converter. Importantly, the upgrade is optional and is designed to be reversible. The Sky interface states that DAI can be converted to USDS 1:1 and USDS can be converted back to DAI, which keeps DAI relevant even as new features are introduced through the Sky ecosystem.
This review focuses on what matters for safety and reliability: how DAI is issued, what stabilizes the peg, and where real risk enters during market stress.
DAI is generated when users lock accepted collateral into on-chain vaults and mint DAI against that collateral. The system is intentionally overcollateralized. That means the collateral value is designed to stay higher than the DAI debt, with buffers that vary by collateral type and risk parameters.
The most direct official overview is the Maker Protocol documentation, which describes DAI generation through vaults, stability fees, and risk parameters set through governance. From a user perspective, the mechanism is a secured debt position: collateral goes in, DAI comes out, and the DAI plus stability fees must be repaid before the collateral can be withdrawn.
This design is powerful because it does not require a centralized issuer holding dollars in a bank account. It is also risky because collateral prices can fall fast.
If collateral value drops far enough that a vault no longer meets its required collateralization ratio, the protocol liquidates the position to protect the system. In plain terms, collateral is sold to cover the DAI debt and a liquidation penalty. Without liquidations, DAI would become undercollateralized during crashes.
Maker’s auction and liquidation mechanisms are documented in detail. A useful reference is the “Auctions of the Maker Protocol” guide, which describes how collateral auctions and debt auctions work at a high level. For deeper technical detail, the Liquidation 2.0 module documentation explains how the system uses Dutch auctions and the role of keeper activity.
The key takeaway is that DAI’s safety is not only “code correctness.” It also depends on liquid markets for collateral, reliable price feeds, and active keeper participation when volatility spikes.
A stablecoin peg is not magic. DAI’s stability is supported by incentives and arbitrage. When DAI trades above $1, minting DAI becomes more attractive because it can be sold at a premium, expanding supply and pushing the price down. When DAI trades below $1, buying DAI and repaying vault debt becomes more attractive, reducing supply and pushing the price up.
In stressed markets, additional mechanisms and risk parameters matter, including the mix of collateral types and how quickly liquidations can happen. If the market moves faster than liquidations can clear, DAI can deviate. That is not theoretical. It is the main risk pattern for decentralized stablecoins.
In 2026, DAI sits alongside USDS as part of the Sky ecosystem. The Sky whitepaper explains that USDS launched with a converter contract that allows free, infinitely liquid conversions between DAI and USDS. The Sky protocol docs also describe a DAI-USDS converter that converts in both directions at a fixed 1:1 ratio and states that no fees can be enabled on that route.
From a practical standpoint, this means DAI does not simply “disappear.” DAI can still be held, used across DeFi, and converted when needed. USDS is positioned as the upgraded token that integrates more tightly with new Sky features, but the 1:1 converter preserves continuity.
The safest way to interpret this in 2026 is that DAI is the legacy stablecoin with deep DeFi integration, while USDS is the ecosystem’s forward path for new incentive features. The existence of the converter reduces migration friction, but it does not remove core stablecoin risks.
DAI’s strongest attribute remains its model. It is not purely dependent on a single centralized reserve manager. The issuance mechanism is transparent and can be inspected on-chain. The liquidation system is designed to force the protocol back toward full collateral backing even during drawdowns.
For users and teams that prioritize permissionless composability, DAI is still a meaningful building block. It shows up in lending markets, DEX liquidity, and treasury strategies that avoid holding only one issuer’s IOU.
DAI can be “safe” relative to many experimental stablecoins, but it is not risk-free. The risks are structural.
Collateral volatility is first. If the protocol is exposed to collateral that becomes illiquid, then liquidations can fail to clear at expected prices. That can push the system toward undercollateralization until auctions stabilize.
Oracle and pricing risk is second. Liquidations and risk engines rely on price feeds. If a feed lags or is manipulated, vaults can be liquidated too late or too early.
Governance and parameter risk is third. Risk parameters, collateral onboarding, and emergency actions are controlled through governance processes. That governance risk is not inherently bad, but it is real and should be treated as part of the stablecoin’s threat model.
Smart contract risk is fourth. Even mature protocols can have implementation risk, upgrade risk, or integration risk at the UI and routing layers.
Finally, there is collateral composition risk. If a large portion of backing relies on centralized assets, then the stablecoin inherits parts of that centralized risk, including blacklisting or seizure at the asset layer. That tradeoff is a recurring theme across the stablecoin landscape.
DAI is easiest to use safely when it is treated like infrastructure, not a meme. Token authenticity matters. Users should verify token addresses via trusted sources and avoid lookalike tokens. The Sky converter is intended to be the canonical path for DAI to USDS upgrades, which is why the official interface at https://sky.money/ is a safer starting point than random links.
Routing matters too. A user can hold DAI safely in self-custody and still lose funds by signing approvals on malicious contracts. The safest operational pattern is conservative: use well-known interfaces, minimize unlimited approvals, and avoid third-party “boost” products that do not explain where yield comes from.
DAI remains one of the most credible decentralized stablecoins in 2026 because its stability is enforced by overcollateralization, liquidations, and transparent on-chain mechanics. The Sky USDS upgrade adds a new layer to the ecosystem, but the 1:1 converter means DAI remains usable and relevant rather than being abruptly deprecated. The real question for safety is not whether DAI is perfect. It is whether users understand the risk engine behind it: collateral quality, liquidation performance, oracle reliability, and governance decisions. When those mechanisms are respected, DAI continues to be a stablecoin that can justify serious use in DeFi and on-chain treasury operations.
