# Welcome to USD.AI

### USD.AI is a synthetic dollar protocol designed to finance the physical infrastructure of AI

Targeting 10-15% APR, it functions like a high-yield bond index tied to income-generating infrastructure equipment. Like most synthetic dollar protocols, the three key aspects of USD.AI are:

> 1. **USDai** — a fully-backed synthetic dollar
> 2. **sUSDai** — the yield-bearing token (counterpart to USDai)
> 3. **Yield** — how the protocol generates yield for sUSDai

{% hint style="info" %}
USDai or sUSDai are not the same as a fiat stablecoin like USDC or USDT

**USDai** is a low risk, fully-backed stablecoin, which allows it to be redeemed instantly at all times. USDai does not pass yield through to holders, instead providing users with deep secondary market liquidity across DeFi and CeFi.

**sUSDai** is the yield-bearing synthetic dollar backed by AI infrastructure assets.  These assets are inherently less liquid than stablecoins, so holders accrue yield for the added risk and withdrawals are also subject to redemption periods. 

**Yield** for sUSDai is generated through loans collateralized by AI infrastructure assets (GPUs). Depositors can earn yield without needing to underwrite or originate individual loans. Any idle capital is always held in Treasury Bills as a base yield and may include other low-risk stablecoins in the future.

Rather than simply offering loans, USD.AI restructures the very architecture of credit through the minting of a low-risk stablecoin (**USDai**) and the pricing of a yield-bearing derivative instrument (**sUSDai)**
