Dai (DAI)

The decentralized dollar. Stable by design, free by nature.

What is Dai?

Dai is a decentralized stablecoin pegged to the US dollar, created and governed entirely by smart contracts and a global community. Unlike USDC or USDT which are backed by dollars in bank accounts, Dai is backed by cryptocurrency collateral locked in transparent, auditable smart contracts on Ethereum.

This distinction matters. Dai cannot be frozen, censored, or seized by any company or government. It is generated through the Maker Protocol, where users deposit collateral assets and mint Dai against them. The system is self-regulating — if collateral values drop, positions are automatically liquidated to keep Dai backed.

As one of the oldest and most battle-tested stablecoins, Dai has maintained its dollar peg through multiple market crashes and black swan events. It is deeply integrated across DeFi as a lending asset, trading pair, and savings instrument.

How Dai Works

Imagine a pawn shop run entirely by code. You deposit collateral worth more than what you want to borrow — say $150 of ETH to generate $100 of Dai. The smart contract holds your collateral and creates new Dai. If your collateral drops in value, the system warns you. If it falls below the safe threshold, the pawn shop sells your collateral automatically. This over-collateralization is what keeps every Dai worth one dollar, without any company holding dollars in a vault.

Team & Development

Dai is created by the Maker Protocol, which was founded by Rune Christensen in 2014. MakerDAO, the decentralized autonomous organization, governs the protocol through MKR token voting. The protocol has been rebranded under the Sky ecosystem, but Dai remains the core stablecoin product. Development is supported by multiple independent teams.

Frequently Asked Questions

How is Dai different from USDC?

USDC is backed by dollars in bank accounts and issued by a company (Circle). Dai is backed by crypto collateral in smart contracts and governed by a DAO. Dai cannot be frozen or censored by any single entity, making it the most decentralized major stablecoin.

What keeps Dai pegged to $1?

Over-collateralization and automated liquidations. Every Dai is backed by more than $1 worth of crypto collateral. If collateral values drop, positions are liquidated to maintain backing. Arbitrage traders also help keep the peg tight on open markets.

Can I earn yield on Dai?

Yes. The Dai Savings Rate (DSR) lets you deposit Dai and earn yield set by MakerDAO governance. Dai is also widely accepted across DeFi lending protocols like Aave and Compound for additional yield opportunities.

Is Dai an ERC-20 token?

Yes. Dai is an ERC-20 token on Ethereum and is also available on Arbitrum, Optimism, Polygon, and other Layer 2 networks. Any Ethereum-compatible wallet like MetaMask can hold Dai.
