Aura runs on the Alephium network. While trading on Aura is collateralized in USDT, the Alephium protocol still uses ALPH for transaction execution (gas) and certain on-chain storage deposits (such as map-entry and contract deposits).

Network execution costs (gas / deposits)Handled automatically by Aura
Aura covers the ALPH required for gas and any related on-chain deposits through atomic swaps at transaction time, so you generally do not need to hold ALPH to use Aura. In practice, users only need USDT to trade (including passkey-based onboarding).

​
Fee collection

All market activities incur a small and consistent trading fee, collected exclusively in USDT:
  • Trading fee — 2.5% on executed volume, charged in USDT
  • Distribution — fees are transparently distributed between market creators, voters (in case of disputes), referrers, and the Aura treasury based on clearly defined and tier-based sharing structures.
This straightforward approach simplifies user interactions and maintains a transparent, fair economic model within the Aura ecosystem.
