How Does Reserve Protocol Work?
A platform that lets anyone create a custom stablecoin backed by a basket of tokens, with RSR token stakers providing insurance against losses. It holds $200M across its stablecoins and raised $13.5M. Its B- grade reflects that the insurance mechanism is self-defeating: RSR's price drops during the exact market conditions when insurance is needed most.

Core Mechanisms
6.1.1
NovelRToken: permissionless overcollateralized stablecoin factory with customizable ERC-20 baskets
Anyone can deploy an RToken backed by a custom basket of ERC-20 tokens. Each RToken maintains its own collateral ratio and risk profile. The permissionless factory model is a novel extension of overcollateralized stablecoin design — no other protocol allows arbitrary basket creation at this scale.
3.1.1
NovelstRSR: RSR staked on individual RTokens provides first-loss overcollateralization insurance
RSR stakers choose which RTokens to insure and earn revenue share in return for first-loss exposure. If an RToken's basket loses value, staked RSR is auctioned to restore backing. This per-RToken insurance model is novel — it distributes and fragments insurance capital across many independent stablecoins.
2.2.1
Revenue from yield-bearing collateral distributed to RSR stakers and RToken holders
RToken baskets can include yield-bearing tokens (cTokens, aTokens, stETH). Revenue generated from these yields is split between RToken holders (as stablecoin appreciation or rebasing) and stRSR holders (as compensation for insurance).
5.1.1
Per-RToken governance by stRSR holders over basket composition and parameters
Each RToken has its own governance by its stRSR holders. They vote on basket changes, collateral parameters, and revenue split ratios. This creates decentralized governance at the individual stablecoin level.
4.2.1
Revenue auctions: protocol sells accrued rewards to buy RSR for staker distribution
When accumulated revenue exceeds a threshold, the protocol runs on-chain auctions to convert rewards to RSR, which is distributed to stakers. Standard auction-based value capture pattern.
6.4.1
Chainlink oracle feeds for collateral valuation and basket rebalancing triggers
RTokens rely on Chainlink price feeds to value basket collateral and trigger rebalancing or insurance auctions when collateral value drops. Standard external oracle dependency.
8.2.1
Multi-chain deployment across Ethereum, Base, and Arbitrum with canonical RTokens
Reserve Protocol deployed on Ethereum mainnet, Base, and Arbitrum. RTokens are canonical on their deployment chain with bridged representations elsewhere.
1.2.1
RSR token vesting with proposed 30B token burn to reduce max supply
RSR has a 100 billion max supply with significant team/investor holdings. Community has proposed burning 30B tokens (~30%) and adopting veRSR governance to reduce dilution and align incentives.
How the Pieces Interact
Insurance auctions sell RSR into the market during stress events. RSR price is correlated with the same market conditions that cause collateral defaults, making the insurance mechanism reflexive — it becomes less effective exactly when it's needed most.
RSR stakers distributing across many RTokens fragments the insurance pool. A major RToken default could drain its stRSR while leaving other RTokens' insurance pools untouched — no cross-subsidy mechanism exists.
Anyone can deploy a malicious RToken basket designed to extract value from RSR stakers via deliberate collateral default. The permissionless model trades safety for composability.
Yield-bearing tokens (aTokens, cTokens) may have exchange rate discrepancies that oracles fail to capture in real-time, allowing undercollateralization to go undetected until materially significant.
Regular predictable revenue auctions buying RSR create front-runnable patterns. In thin markets, this concentrates execution to MEV extractors and reduces effective yield to stakers.
What Could Go Wrong
- RSR insurance mechanism is reflexive: RSR price drops during exactly the stress events when insurance is needed, potentially creating a death spiral
- Permissionless RToken creation allows anyone to deploy baskets that could trap RSR stakers in malicious or poorly-designed collateral configurations
- Multi-collateral basket complexity creates compounding tail risk — failure of any single basket component can cascade through the RSR insurance layer to affect all RTokens
RToken Collateral Default and RSR Insurance Spiral
ModerateTrigger: A yield-bearing collateral token in a major RToken's basket (e.g., cUSDC or aDAI) suffers a depeg or protocol exploit, triggering the RSR backstop mechanism
- 1.A collateral token in a popular RToken basket depegs 10%+ due to underlying protocol exploit (e.g., Aave or Compound vulnerability) — RToken becomes undercollateralized as basket value drops below 1:1 backing
- 2.Protocol automatically auctions staked RSR (stRSR) to cover the collateral shortfall and restore basket parity — RSR selling pressure from insurance auction crashes RSR price 30-50%, reducing the remaining insurance buffer value
- 3.RSR price crash triggers second-order stRSR auctions as initial proceeds are insufficient at lower RSR prices — Reflexive death spiral: more RSR sold to cover shortfall, further depressing price, requiring even more RSR to be auctioned
- 4.RSR stakers across other RTokens panic-unstake to avoid being swept into insurance auctions — Multiple RTokens simultaneously lose their overcollateralization buffer, creating systemic risk across the entire Reserve ecosystem
