# RAI Dollar (RD)

**Peg:** US Dollar

**Backing:** Crypto-Collateralized

**Governance:** Decentralized (DeFi)

**Status:** pre-launch

## Overview

The Reflexer team's answer to its own experiment: RAI's controller, this time aimed squarely at $1 — and, as ever, with no admin keys to fix it if they are wrong.

RAI spent years proving that a stablecoin could be steered by an on-chain controller rather than a committee, and the mechanism worked; the market followed the redemption price faithfully. What it never solved was that the redemption price was not a dollar, and most of the market could not get past that. RAI Dollar keeps the machinery and pins the target. RD is an immutable CDP stablecoin on Ethereum where a PI controller reads a 24-hour TWAP of the market price and moves one system-wide borrow rate, bounded to 0.25-50% APY around a 2% bias, until supply and demand pull the price back to $1 — with Liquity's redemption arbitrage underneath as the floor. The par lever RAI made famous is still in the box, but bounded to $0.75-$1.30 and moving no faster than a tenth of a cent an hour, held for the extremes rather than left to float. Collateral sits in eight isolated branches — WETH, wstETH, rETH, weETH, WBTC, tBTC, sUSDS, and PAXG — each with its own troves, stability pool, and shutdown path, and the design answers the question Liquity V2 left open by routing a slice of healthy-branch fees to repair a branch that ends up undercollateralized, rather than convening a vote. Borrowers who dislike the redemption queue can pay a floating surcharge for a Redemption Shield that funds a matching discount for everyone who does not. It is a genuinely thoughtful synthesis, and it is also entirely theoretical: no contracts are deployed, the address registry reads TBD, the core repository is private, and the audits are still in progress — funded in part by an Ethereum Foundation subsidy awarded in August 2026. Immutability cuts both ways, and whatever ships is what runs, permanently.

## Collateral

Overcollateralized crypto locked in eight isolated Ethereum branches, each with its own troves, Stability Pool, interest rate, and price feed: WETH (110% MCR), wstETH (120%), rETH (120%), weETH (130%), WBTC (130%), tBTC (120%), sUSDS (105%), and PAXG (130%). Total RD supply is designed to equal outstanding trove debt plus a small gas-compensation float.

## Peg Mechanism

Immutable CDP targeting $1. Holders can redeem RD for branch collateral at par less a fee, setting a price floor; an on-chain PI controller reads a 24-hour TWAP of RD's market price from a curated Balancer pool and moves a single system-wide borrow rate (0.25%-50% APY around a 2% bias) to steer supply and demand. Under sustained extreme deviation a second lever adjusts the internal redemption price (par) within a bounded $0.75-$1.30 band at no more than $0.001/hour. A baton keeps rate mode and par mode from acting at once.
