Overview

Brila DAT user guides, explanations, contract reference, and deployment details

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 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.

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.
