Dai (DAI) is a decentralized stablecoin that operates on the Ethereum blockchain. Its primary function is to maintain a stable value, usually pegged 1:1 to the US Dollar (USD), through a combination of smart contracts and collateralized debt positions (CDPs). Unlike centralized stablecoins like Tether (USDT), Dai is governed by the decentralized autonomous organization (DAO) known as MakerDAO.
Mechanism of Price Stability
Smart Contracts and Collateral
Dai achieves price stability through an intricate system of smart contracts and collateral. Users lock up assets, such as Ether (ETH), as collateral in the MakerDAO protocol to mint new Dai tokens. These assets are held in Collateralized Debt Positions (CDPs).
Over-collateralization
A key feature of Dai’s stability mechanism is over-collateralization. Typically, users need to deposit more than $1.50 in ETH to generate $1 of Dai, compensating for potential drops in the asset value. This approach minimizes the risk of insolvency and maintains the system’s integrity.
Target Rate Feedback Mechanism (TRFM)
The Target Rate Feedback Mechanism (TRFM) is an advanced monetary policy tool used by Dai to stabilize its peg. When Dai’s market price deviates from the target price (usually $1), TRFM adjusts the collateralization ratios to encourage or discourage the generation of new Dai, driving the price back to its peg.
Types of Collateral
Multi-Collateral Dai (MCD)
Originally, Dai was generated using only ETH, but the introduction of Multi-Collateral Dai (MCD) enables the use of various assets as collateral. This diversification reduces risk and enhances system stability.
Special Considerations
Decentralization and Governance
Dai is unique due to its decentralized governance structure managed by MakerDAO. Community members, through the MKR token, vote on key decisions, such as adding new collateral types and modifying collateralization ratios.
Integration in Decentralized Finance (DeFi)
Dai is a cornerstone of many Decentralized Finance (DeFi) applications. From lending platforms to decentralized exchanges, it serves as a stable medium of exchange and a store of value.
Examples and Use Cases
DeFi Protocols
Many DeFi protocols integrate Dai to offer financial services such as lending, borrowing, and trading in a stable currency that mitigates the inherent volatility of cryptocurrencies.
Remittances
Dai is used for international remittances, providing a cost-effective and swift alternative to traditional banking systems.
Historical Context
Creation and Evolution
Dai was launched in December 2017 by the MakerDAO project. Initially, Single-Collateral Dai (SCD) was backed solely by ETH. Multi-Collateral Dai (MCD), which supports various assets, was introduced in November 2019.
Applicability and Comparison
Vs. Centralized Stablecoins
Compared to centralized stablecoins like Tether (USDT), Dai’s decentralized nature means it is less susceptible to regulatory risks and lacks a single point of failure, enhancing security and resilience.
Vs. Algorithmic Stablecoins
Unlike algorithmic stablecoins, which rely on algorithms and market behaviors to maintain stability, Dai uses tangible assets as collateral, offering a more reliable stabilization mechanism.
