What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized digital dollar. Unlike stablecoins backed by bank-held fiat reserves, DAI is generated when users deposit approved cryptocurrencies like ETH or WBTC as collateral into Maker Vaults. This overcollateralization—typically requiring 150% or more value in crypto—acts as a buffer against market volatility, ensuring each DAI in circulation is backed by excess value. Its primary value is offering censorship-resistant stability for payments, savings, and as a base currency throughout decentralized finance (DeFi).

2. Technology & Governance

Technically, DAI is an ERC-20 token on Ethereum, secured by the network's underlying proof-of-stake consensus. Its stability is maintained algorithmically through a system of smart contracts that automatically liquidate undercollateralized vaults. Crucially, DAI has no central issuer. Instead, the Maker Protocol (rebranded as Sky Protocol) is governed by a decentralized autonomous organization (DAO). Holders of its governance tokens (originally MKR, now transitioning to SKY) vote on key parameters like collateral types, stability fees, and system upgrades (CoinMarketCap).

3. Current State & Transition

As of 2026, DAI exists within a broader ecosystem evolution. MakerDAO's "Endgame" plan has transitioned the protocol to the Sky ecosystem, which introduces USDS as a new, upgradable stablecoin. DAI's immutable smart contracts remain active, and users can often upgrade DAI to USDS at a 1:1 ratio to access new features and yields. This means DAI is both a foundational DeFi asset and a legacy token in the process of being succeeded by a new system.

Conclusion

Fundamentally, DAI is a pioneering experiment in creating trust-minimized, algorithmic money, whose value and rules are determined by a decentralized community rather than a central entity. How will its legacy as a purely decentralized stablecoin influence the design of future digital currencies?
