In this comprehensive comparison, we’ll analyze the history, mechanics, risks, and future prospects of USDC and DAI to help you decide which stablecoin suits your needs.
The History of Circle (USDC) and DAI Coin (DAI)
USDC: Launched by Circle
- Year: 2018
- Backing: Initially USD reserves, now includes cash equivalents (61%), US Treasury bonds, and commercial paper.
- Transparency: Circle provides periodic reserve reports but lacks independent audits.
- Recent Challenges: Lost its peg temporarily during the 2023 SVB collapse, which held $3.3B of USDC reserves.
DAI: Launched by MakerDAO
- Year: 2017
- Backing: Over-collateralized by cryptocurrencies (ETH, USDC, WBTC) and real-world assets (since 2022).

- Criticism: Dependency on USDC and centralized decision-making.
How Do USDC and DAI Work?
USDC’s Pegging Mechanism

- Smart Contracts: Uses Maker Protocol’s Collateralized Debt Positions (CDPs) to automate liquidation if collateral value drops.
