# Ring USD (USDR)

**Peg:** US Dollar

**Backing:** Crypto-Collateralized

**Governance:** CeFi-Dependent

**Status:** active

## Overview

Ring Protocol's USDR is a small crypto-backed synthetic dollar with modest documentation; the dashboard models the reserve stack conservatively as protocol collateral and liquidity positions. Ring USD is a crypto-backed synthetic dollar from Ring Protocol. Its public footprint is small, so the dashboard models the reserve stack conservatively as protocol collateral and liquidity positions rather than a granular attested basket. The Ethereum supply is eligible for curated reserve validation, but {{term:redemption}}redemption{{/term}} quality still depends on Ring-specific mechanics and protocol liquidity. That makes USDR a long-tail collateralized dollar with meaningful smart-contract and governance dependency.

## Collateral

Ring protocol crypto collateral and strategy assets managed through the protocol reserve system

## Peg Mechanism

RUSD is collateralized by a Protocol Controlled Value (PCV) reserve funded through bonding-curve issuance; PCV is allocated to liquidity and the token can be over- or under-collateralized depending on reserve conditions; no holder-exercisable redemption route is source-reviewed for Pharos backstop scoring
