How Dai and Tether are built

How Dai works

The collateral is always worth more than the amount of DAI issued against it. If the collateral falls in price, the position goes to automatic liquidation and the backing is preserved. Interest rates set by the governance mechanism help hold the price near a dollar.

What Dai is for

In DeFi, DAI is used to build lending, borrowing and liquidity pools. It is also taken by those who want a dollar asset managed by a protocol rather than by a single company.

How Tether works

USDT has no blockchain of its own. The same dollar token lives in several networks at once: TRON, Ethereum, BNB Smart Chain, Solana, TON, Polygon, Arbitrum and others. You cannot move the token from one network to another directly — that is done through exchanges and bridges.

What Tether is for

People sit out drawdowns in USDT, settle deals, send dollars abroad and pay for services with it. By trading volume it is the market's number one asset and the most familiar way to lock in the result after selling other coins.
