# Oxy-Nodes

Oxy-Fi uses innovations including a tiered node system to provide high yields sustainably. To make the Oxy-Fi protocol accessible to smaller wallets, $OXY holders can create a node with 1 $OXY token.

**We implemented a unique reward mechanism that ensures the highest rewards are provided to the most committed members of our community, facilitating one of the most sustainable models in DeFi.**

There are five different tiers of Oxy Nodes, each of which requires an increasing amount of $OXY to create, and each of which respectively provides an increased APR. These nodes can be upgraded to higher tier nodes at any time.
