Dai (DAI) is a type of cryptocurrency known as a stablecoin, which is designed to keep a steady value close to one US dollar. Unlike cryptocurrencies such as Bitcoin or Ethereum, whose prices can change a lot, DAI aims to stay stable.
DAI is different from stablecoins like USDT (Tether) or USDC (Circle) because it is decentralized. While those coins are issued and backed by companies that hold traditional currency in bank accounts, DAI is managed by Sky (previously called MakerDAO), a decentralized autonomous organization (DAO) where community members vote on changes to the system.
Created in 2017, DAI is used in many areas of decentralized finance (DeFi), including borrowing, lending, trading, and making payments, without relying on banks.
DAI is generated through smart contracts on the Ethereum blockchain. Instead of being backed by money held in banks, it is backed by crypto assets used as collateral. This setup keeps DAI’s value close to one dollar and allows anyone to verify how it works on the blockchain.
The DAI system has a special token called MKR, which gives holders a say in how the system works. People who own MKR can vote on important settings, like how much it costs to borrow DAI (the stability fee) and how much interest DAI holders earn (the DAI Savings Rate). By adjusting these settings when market conditions change, MKR holders help keep DAI’s value steady around $1.
DAI (DAI) Key Points
- Launched in 2017 by MakerDAO (now known as Sky) as the first decentralized stablecoin
- Pegged to the US dollar, designed to maintain a value close to $1
- Backed by crypto assets such as ETH and USDC, rather than traditional fiat reserves
- Governed by Sky, a decentralized autonomous organization (DAO)
- Used across DeFi platforms for lending, borrowing, trading, and payments
History of Dai (DAI)
DAI was created by MakerDAO, founded by Rune Christensen, and launched in 2017 as a decentralized stablecoin aimed at reducing crypto volatility. Early DAI was backed only by Ethereum (ETH), with users locking ETH in smart contracts to generate new tokens.
In 2019, MakerDAO introduced Multi-Collateral DAI, allowing assets like USDC and WBTC as collateral and adding community governance through the MKR token.
DAI became a key part of DeFi, used for lending, trading, and payments. Over time, reliance on centralized collateral raised concerns about decentralization.
In 2024, MakerDAO began rebranding to Sky, introducing new tokens USDS and SKY as part of its updated system. As of October 2025, the transition is ongoing, and DAI continues to operate and circulate across DeFi platforms alongside the new Sky framework.
Dai (DAI) Staking & Collateralization
Unlike Bitcoin, which is created through mining, or Ethereum, which uses staking, DAI isn’t produced by competing computers or locked-up tokens. Instead, it’s generated through collateral, kind of like taking out a secured loan, but done automatically through smart contracts.
Imagine you deposit your car as collateral to borrow money. The lender gives you less money than the car is worth, so if you don’t pay it back, they can cover the loss by selling the car. DAI works in a similar way:
- You lock up crypto, like ETH or USDC, in a digital “vault.”
- You receive DAI, but always less than the total value of what you put in (this is called over-collateralization).
- To get your crypto back, you repay the DAI you borrowed, plus a small stability fee.
This setup ensures that every DAI in circulation is backed by more value than it represents, helping it stay close to $1 even when crypto prices move around.
DAI (DAI) Use Cases & Real-World Applications
DAI has become one of the most widely used stablecoins in decentralized finance (DeFi) and beyond. Its utility stems from its stability and decentralization:
- Lending and borrowing: Platforms like Aave and Compound allow users to lend DAI to earn interest or borrow DAI against crypto collateral.
- Trading and liquidity: DAI is a common trading pair on decentralized exchanges (DEXs), enabling easy swaps between assets.
- Payments: Because DAI is stable, it can be used for everyday payments, shielding users from crypto volatility.
- Remittances: DAI’s dollar peg makes it suitable for cross-border transfers without relying on banks.
- Hedge against volatility: Traders use DAI as a “safe haven” when crypto markets are turbulent.
Its decentralized nature makes DAI especially appealing in countries with unstable banking systems or strict financial controls.
Dai (DAI) Vs. Tether (USDT)
DAI is often compared to centralized stablecoins like USDT. While both aim to maintain a $1 value, they operate very differently:
- Collateral: DAI is backed by crypto collateral stored in smart contracts; all USDT tokens are designed to maintain a 1-to-1 peg with the corresponding fiat currency and are claimed to be fully backed by Tether’s reserves.
- Governance: DAI is governed by Sky, a decentralized community; USDT is issued by a private company.
- Transparency: DAI’s reserves are visible on-chain at all times; USDT’s backing has faced criticism over transparency due to a lack of proof-of-reserves (PoR) reports.
- Censorship resistance: DAI is harder to freeze or censor since it’s decentralized; USDT can be frozen by its issuer.
This makes DAI more aligned with crypto’s decentralized ethos, though USDT remains more widely used due to its early dominance and liquidity.
How To Buy Dai (DAI)
DAI is widely available and easy to purchase:
- Centralized exchanges (CEXs): Available on major exchanges like Coinbase, Binance, and Kraken.
- Decentralized exchanges (DEXs): Users can swap ETH, USDC, or other tokens for DAI using platforms like Uniswap or Curve.
- Apps and fintechs: Wallets such as MetaMask and platforms like Revolut support DAI purchases.
- Fiat on-ramps: Some services allow direct purchase of DAI with credit cards or bank transfers, while others require converting from another crypto.
After purchase, DAI can be stored in any Ethereum-compatible wallet, including software wallets like MetaMask or hardware wallets like Ledger.
DAI FAQs
Is DAI safe to invest in?
DAI is considered safer than many other cryptocurrencies due to its stable peg to the dollar and transparent collateralization. However, it still carries risks such as smart contract vulnerabilities and over-reliance on collateral like USDC.
Who created DAI ?
DAI was created by MakerDAO, founded by Rune Christensen in 2015. The stablecoin launched in 2017 and has since evolved with the support of the MakerDAO community.
Does DAI have a maximum supply?
No, DAI does not have a fixed maximum supply. Its supply expands and contracts based on how much collateral is deposited in Maker Vaults.
Can I use DAI for everyday payments?
Yes. Because DAI maintains a stable $1 value, it’s increasingly used for online payments, remittances, and even merchant transactions. Its integration with DeFi apps also allows people to spend DAI directly from wallets.
