# Welcome

Astralis is the first compute marketplace to make **USDT the default unit of account for GPU resources**. Built on **Plasma’s gas-free stablecoin rails**, Astralis allows compute buyers and providers to transact entirely in USDT, removing volatility and dual-currency friction.

Where existing GPU networks denominate compute in their own tokens, Astralis aligns with the asset that already dominates on-chain liquidity. Every GPU cycle is priced, escrowed, and settled directly in USDT.

* **Predictable Costs** → Buyers know exactly what they will pay per GPU-hour.
* **Stable Revenues** → Providers are paid in a fiat-equivalent asset, not a volatile token.
* **Single-Currency UX** → Jobs require only USDT; no gas tokens or conversions.
* **Enterprise-Ready Pricing** → Costs are expressed in dollars, matching SaaS models.

By transforming Plasma’s gas-free USDT rails into a compute market, Astralis removes the structural barriers that have limited decentralized GPU adoption.
