# Overview

Brila DAT (`$DAT`) is an **elastic-supply token on HyperEVM that targets a price of $1.00**. It is *not* collateralised like a typical stablecoin: instead, the protocol expands and contracts every holder's balance ("rebases") to push DAT's market price back toward $1, and harvests the USD appreciation of its HYPE liquidity into a treasury along the way.

## How this documentation is organised

This documentation follows the [Diátaxis](https://diataxis.fr/) framework — four kinds of material, each serving a different need. They are kept deliberately separate.

## The one-paragraph mental model

You hold DAT. During twice-daily windows, a keeper can trigger a **rebase**: the protocol reads DAT's price in USD (the DAT/WHYPE pool's time-weighted price, multiplied by a WHYPE→USD oracle), and if that price is outside a ±5% band around $1.00, it changes *everyone's* balance proportionally to nudge the price back. Above peg, balances grow; below peg, they shrink. Scaling-factor changes are proportional; positive-rebase treasury mints can dilute holders' percentage ownership. See [Elastic supply](/brila-dat/explanation/elastic-supply.md).

> **Status:** the production peg mode is **USD ($1.00)**. The codebase also supports a RATIO mode (1 DAT ≈ 1 reserve token); these guides describe the USD-mode launch. The peg mode is fixed immutably at deployment.
