# $PETRA

\$PETRA is the native utility token of Perpetra. It aligns the interests of traders, stakers, and the protocol into a single flywheel: trade more, earn more, pay less.

## Why a Token?

Perpetra generates real revenue from every trade. \$PETRA gives the community a way to participate in that upside.

* **Earn** a share of trading fees by staking

## Supply

| Parameter        | Value                       |
| ---------------- | --------------------------- |
| **Max Supply**   | 100,000,000 PETRA           |
| **Inflation**    | None — hard cap, no minting |
| **Denomination** | ERC-20 on Robinhood Chain   |

100 million tokens. That's the ceiling. The full breakdown is in [Tokenomics](/petra/tokenomics).

<Info>
  \$PETRA is a utility token. It does not represent equity, ownership, or a claim on protocol assets. Fee sharing is a reward for active participation in the ecosystem.

## How It Fits Together

Perpetra earns fees from every trade (taker fees, liquidation fees). A portion of that revenue flows to the **Staking Vault**, where \$PETRA stakers earn USDC proportional to their share. Staking also moves you into better fee tiers—so active traders are incentivized to hold and stake rather than sell.

The result: traders who use Perpetra are rewarded for doing exactly what they're already doing.
