Що таке стейблкоїн Dai (DAI)? Як працюють децентралізовані стейблкоїни та їхні перспективи розвитку

On the Gate platform, the latest market price for Bridged Dai Stablecoin (StarkGate) is $0.99934. Over the past 24 hours, the price has seen minor fluctuations, dropping by 0.04%. Since its launch in 2017, DAI has operated stably for seven years, making it one of the earliest and most reliable algorithmic stablecoins in the DeFi sector.

DAI Market Performance and Overview

As a leading stablecoin by market capitalization, DAI is currently trading at $0.99934 on Gate, with a 24-hour price change of just -0.04%, demonstrating exceptional stability. Looking at its long-term price trends, DAI’s historical performance further validates its reliability as a stablecoin. Since 2021, despite multiple episodes of extreme volatility in the crypto market, DAI’s year-end price has consistently remained near $1.

DAI’s extremely low volatility makes it a unique safe-haven asset in the cryptocurrency market. Historical data shows DAI’s all-time high is just $1.38, and its all-time low is $0.8359. Compared to other cryptocurrencies that often experience double- or even triple-digit price swings, DAI’s price range is remarkably narrow.

Core Design of the Decentralized Stability Mechanism

DAI’s stability doesn’t rely on centralized institutions holding USD reserves. Instead, it’s achieved through the complex mechanisms of the MakerDAO protocol. Overcollateralization serves as the system’s first line of defense, requiring users to lock up crypto assets worth more than the amount of DAI they wish to borrow. For example, if you want to borrow 100 DAI, the system will require you to lock up $150 worth of ETH as collateral. Even if the ETH price drops by 20%, the remaining collateral would still be worth $120, enough to cover your debt and maintain system stability.

Triple Mechanism to Maintain the $1 Peg

When DAI’s price deviates from its $1 peg, the MakerDAO protocol automatically adjusts supply and demand through three complementary mechanisms.

Overcollateralization itself acts as a stabilizer. If DAI falls to $0.95, arbitrageurs can buy 1 DAI for $0.95, use it to repay debt, and unlock their collateral, earning a $0.05 profit. This arbitrage buying helps push DAI’s price back toward $1.

The Stability Fee—essentially the borrowing interest rate—directly affects DAI’s supply. When DAI’s price drops, increasing the stability fee raises borrowing costs, encouraging users to repay loans early and burn DAI, reducing supply and helping the price recover.

The DAI Savings Rate (DSR) adjusts DAI’s price from the demand side. Raising the savings rate increases returns for DAI deposits, attracting more buyers and holders, boosting demand, and pushing the price higher. Together, these three tools form a dual supply-demand adjustment system that keeps DAI’s price stable.

Real-World Use Cases for DAI

As a core stablecoin in the DeFi ecosystem, DAI plays a key role in multiple areas. In arbitrage trading, users can use $1,000 worth of ETH as collateral to generate about 600 DAI, then use those DAI to buy more ETH. For users holding large amounts of Bitcoin, DAI is also an important hedging tool. If you want to lock in gains without selling your BTC, you can collateralize it to mint DAI and withdraw funds, then buy back Bitcoin after the market rebounds.

Cross-border transfers are another major application for DAI. On the blockchain, DAI enables instant transfers without a bank account, especially useful for financial needs in emerging markets. In a DeFi environment where yields are generally declining, depositing DAI into savings contracts to earn interest has also become a steady way to generate returns.

DAI’s Future Role in the AI Agent Economy

As blockchain and artificial intelligence technologies converge, DAI is poised to play a key role in the future decentralized AI agent economy.

According to the Ethereum Foundation dAI team’s 2026 roadmap, Ethereum aims to become the global settlement and coordination layer for decentralized AI agents. In this vision, the ERC-8004 and x402 protocols serve as two foundational pillars. ERC-8004, jointly developed by the dAI team and Consensys, primarily addresses the "discovery" and "trust" issues for AI agents. The protocol establishes a standardized trust framework through three registries: the identity registry mints a unique ERC-721 token as a "machine passport" for each AI agent; the reputation registry records each agent’s historical performance; and the attestation registry provides cryptographic proofs for high-value computational results.

Meanwhile, the x402 protocol, designed by Coinbase, enables AI agents to autonomously complete the entire "request-payment-consumption" process. By combining ERC-8004’s identity and reputation system with x402’s micropayment capabilities, DAI is expected to become the preferred medium of value exchange among AI agents, playing a central role in the decentralized AI economy.

How to Use DAI on Gate

For users looking to trade or use DAI, Gate offers a convenient experience. You can directly buy or sell DAI/USDT in the spot market, with the current real-time price at $1. If you need to exchange DAI for other cryptocurrencies, Gate also provides an intuitive swap tool. Simply enter the amount of DAI you want to exchange, select the target cryptocurrency, and the system will automatically calculate the result. The latest data shows that 100 DAI can be exchanged for $100.1, and 1,000 DAI for $1,001.

DAI can also be exchanged for other major cryptocurrencies. For example, 1 DAI is approximately equal to 0.005632 BTC or 0.1664 ETH. These exchange options give users greater flexibility in managing their funds.

Despite DAI’s sophisticated mechanism, users should remain aware of associated risks. Extreme market conditions are a primary challenge—for example, if ETH were to suddenly crash by 50% overnight, the collateral value might not cover outstanding debt. All DAI system parameters are governed by MKR holders through voting, which in theory could lead to excessive centralization. While the risk of smart contract attacks is relatively low, it remains a concern for all DeFi protocols. It’s also important to note that, unlike stablecoins such as USDC and USDT that are fully backed by fiat reserves, DAI maintains its peg through algorithmic mechanisms and overcollateralized crypto assets. This means the system could face stress under extreme market conditions. Additionally, a significant portion of DAI’s collateral is USDC—if USDC experiences a liquidity crisis or regulatory issues, DAI’s stability could also be affected.

According to Gate platform data, the trading price for Bridged Dai Stablecoin (StarkGate) consistently hovers around $1, with 10,000 DAI exchanging for $10,010. As of early January 2026, the DAI stablecoin remains governed by the MakerDAO community, and there is no cap on total issuance—as long as there is sufficient collateral, new DAI can continue to be minted. This mechanism ensures that the DAI system can flexibly respond to ever-changing market demand.
