What Is Sai?
Sai (SAI) is the original single-collateral version of Dai, a decentralized stablecoin built entirely on the Ethereum blockchain. Its core purpose is straightforward: to provide a stable, dollar-pegged asset without relying on any centralized institution. While traditional stablecoins like Tether depend on a company holding real US dollars in a bank, Sai achieves its $1 peg through smart contracts and collateralized debt positions — entirely on-chain and without a central authority that could be shut down or censored. Sai was created by MakerDAO and was the first iteration of the Dai stablecoin, backed solely by Ethereum (ETH) as collateral. When MakerDAO upgraded its system to support multiple collateral types, the original version was renamed Sai to distinguish it from the newer, more flexible multi-collateral Dai. This makes SAI a historically significant token in the DeFi space — it was one of the first live examples of a decentralized, algorithmic stablecoin functioning in the real world. What makes Sai different is its trustless design. There's no company, no bank, and no single point of failure. It operates through transparent smart contracts on Ethereum, meaning anyone can verify how the system works at any time. For those interested in DeFi history and decentralized finance primitives, Sai represents a foundational building block of what the ecosystem has become today.

Frequently Asked Questions
What is Sai and how does it work?
Sai is the original single-collateral version of Dai, a decentralized stablecoin built on Ethereum that is pegged to $1 USD. Unlike centralized stablecoins backed by a company holding real dollars, Sai maintained its peg through smart contracts and ETH-backed collateral positions — no banks, no middlemen. When MakerDAO upgraded to a multi-collateral system, the original version was rebranded as Sai to distinguish it from the newer Dai. It remains a significant artifact in the history of decentralized finance.
Where is the best place to buy SAI?
SAI is currently available on Gate.io and MEXC, both of which are well-established crypto exchanges with broad token listings. Gate.io is known for its wide selection of altcoins and relatively competitive trading fees, while MEXC is popular for its user-friendly interface and accessibility in multiple regions. The best choice depends on your location, preferred payment method, and fee tolerance — it's worth checking both before deciding.
Is Sai a good investment?
Sai occupies an unusual position in the market — as the original single-collateral Dai, it carries historical significance in DeFi, but it has largely been superseded by the upgraded multi-collateral Dai system. This means its utility as an active stablecoin is limited compared to its successor, which introduces its own set of risks and considerations around liquidity and long-term demand. Like any crypto asset, SAI can be subject to market volatility and shifting ecosystem priorities. We'd encourage you to research the MakerDAO ecosystem thoroughly and consider your own risk tolerance before making any decisions.
