What Is MakerDAO and DAI?

MakerDAO is one of crypto's oldest experiments in building a stablecoin without a bank holding the cash. Instead of a company promising "1 token = 1 dollar," it uses smart contracts, locked-up collateral, and community governance to keep the DAI stablecoin near $1. Here is how it actually works, and where the cracks can show.

MakerDAO, MKR, and DAI: the three pieces

It is easy to mix up the names, so let's separate them clearly before going deeper. MakerDAO is built on Ethereum and runs entirely on smart contracts, meaning the rules are enforced by code rather than a corporate treasury.

The simplest way to think about it: DAI is the dollar-pegged coin you use, and MKR is the "voting share" that controls how the machine behaves. MakerDAO is the machine itself.

How DAI is actually created (collateral vaults)

Unlike a centralized stablecoin where a company holds dollars in a bank and mints tokens against them, DAI is born when someone locks up crypto collateral and borrows DAI against it. This happens inside what Maker calls a vault.

The key idea is overcollateralization: you must deposit more value than you borrow. This buffer protects the system if the collateral price falls.

1. A user deposits crypto (for example, ETH) into a vault.
2. They generate DAI against it, but only up to a limit well below the deposit's value.
3. To get the collateral back, they repay the DAI plus a stability fee (an interest-like charge).
4. The returned DAI is destroyed, keeping supply tied to real backing.

This design is a cornerstone of decentralized finance (DeFi): no application form, no credit check, and no company deciding who can borrow. The collateral and the code do the work.

What keeps DAI near $1?

A peg is only as good as the mechanisms defending it. DAI uses several at once rather than relying on a single promise.

• Overcollateralized backing — every DAI is supported by more than $1 of locked assets, so it is not created out of thin air.
• The stability fee — raising or lowering this fee makes borrowing DAI more or less attractive, nudging supply up or down.
• The DAI Savings Rate (DSR) — letting holders earn yield on deposited DAI changes demand to hold it.
• Arbitrage — if DAI trades at $0.98, traders can buy it cheaply and repay debt at $1, profiting and pushing the price back toward the peg.
• MKR as a backstop — in a severe shortfall, the system can mint and sell new MKR to recapitalize, which is why MKR holders are incentivized to govern responsibly.

Over time MakerDAO also added other forms of collateral, including other stablecoins and real-world assets, to improve stability. That broadened the backing but also introduced new dependencies — a tradeoff worth keeping in mind, since some of those assets sit outside pure crypto.

What MKR governance does

MKR is not just a speculative coin; it carries voting power. Holders use it to decide the parameters that keep the whole system safe. Decisions are made through on-chain votes, and changes execute automatically via smart contracts once approved.

This is a real, working example of decentralized governance — but "decentralized" does not mean "risk-free." Voter turnout can be low, and large holders can carry outsized influence. Good intentions in governance do not guarantee good outcomes.

The honest risks

DAI has survived for years and through multiple market crashes, which is a meaningful track record. But no stablecoin is truly "safe," and a balanced view matters more than a comfortable one.

• Smart contract risk — bugs or exploits in the code could cause losses. Code can fail even when the economics are sound.
• Collateral risk — sharp crashes can trigger mass liquidations; in extreme volatility, liquidations may not fully cover debt.
• Centralization creep — reliance on other stablecoins and real-world assets means DAI is no longer purely crypto-backed, importing outside risks.
• Governance risk — a flawed or captured vote could weaken the system's safeguards.
• Peg risk — DAI can and does drift slightly from $1; "stable" means designed to stay near a target, not legally guaranteed.

If you are new to the space, it helps to first understand the basics of how blockchains work and how holding assets in a self-custodied wallet differs from leaving them on an exchange. Understanding the plumbing makes the risks far less abstract.

Key takeaways

• DAI is a stablecoin that aims to stay near $1 using locked crypto collateral, not a company's bank reserves.
• DAI is created when users borrow against overcollateralized vaults, and destroyed when those loans are repaid.
• MKR holders govern the system, setting collateral rules, fees, and which assets are accepted.
• The model is genuinely innovative but carries smart contract, collateral, governance, and peg risks.
