reUSDe: An Overview

reUSDe is an ERC-20 performance token issued by the Re Protocol that embodies a junior-tranche stake in a reinsurance portfolio. It is structured to absorb initial losses as the first-loss capital layer, taking underwriting downside before senior capital is impacted.

Overview

As the protocol’s higher-risk instrument, reUSDe participates in a capital pool tied to reinsurance operations. Because it occupies the junior slice of the capital stack, it bears losses ahead of senior holders; in return, token holders are eligible to receive a portion of remaining underwriting gains after claims, fees, and obligations are settled. The token’s worth increases over time according to a target net asset value that reflects periodic evaluations of portfolio performance.

Contributions are deployed as contingent capital that underwrites reinsurance obligations, commonly routed through regulated trust arrangements to provide collateral for policies. When claims surpass senior buffers and reserves, capital attributed to reUSDe is used to cover deficits; conversely, profitable underwriting expands token value. Withdrawals occur on a cadence tied to the actuarial release of surplus capital, and any deposits awaiting placement may earn external yield until allocated. The protocol maintains transparency through oracle feeds, third-party reserve attestations, and audited smart contracts.

Capital Structure and Function

The token’s behavior and risk/return profile are defined by its placement inside the Re Protocol’s capital stack, which prescribes how gains and losses flow among participants.

Position in the Capital Stack

reUSDe serves as the junior tranche and is subordinate to the protocol’s senior token, reUSD. Its main role is to function as a loss-absorbing buffer so that the senior tranche—designed for principal preservation and steadier yield—remains protected except in extreme loss events. As a result, reUSDe does not provide principal protection, and its value moves directly with the insurance portfolio’s outcomes. In adverse scenarios where claims exceed the protocol’s reserves and senior capital, assets supporting reUSDe are reduced to satisfy claims, lowering the token’s value.

The Capital Waterfall

The protocol implements a sequential "capital waterfall" to prioritize payments and allocate underwriting returns. This ordered mechanism ensures that senior liabilities are fulfilled before any surplus is distributed to reUSDe holders.

• Insurance Claims: Paying claims arising from the underlying reinsurance policies is the foremost obligation.
• Underwriting and Operational Fees: Costs tied to underwriting, legal, and operational management are settled after claims.
• reUSD Accruals: Yield obligations owed to holders of the senior reUSD token are paid next.
• Profit Distribution to reUSDe Holders: Once senior claims and expenses are covered, remaining underwriting surplus is allocated to reUSDe holders, which increases the token’s value.
• Protocol Treasury: Any residual profits after distributions to reUSDe holders are directed to the Re Protocol’s treasury.

Token Mechanics

Pricing Mechanism

The token’s valuation is governed by a Target Net Asset Value, commonly abbreviated as tNAV.

Return Generation

reUSDe holders primarily earn from surplus underwriting profits; positive underwriting results raise the token’s tNAV. Additionally, capital that has been deposited but not yet placed into a reinsurance trust generates yield via external strategies. Specifically, idle funds are allocated to Ethena's sUSDe, and the returns from that allocation contribute to increases in the reUSDe tNAV.

• Target Net Asset Value (tNAV): The tNAV denotes the intrinsic reference value of each reUSDe token. It is computed on a quarterly basis using audited Profit & Loss (P\\&L) statements and detailed actuarial reports that evaluate the reinsurance portfolio’s performance. The updated tNAV is published through a public API and an on-chain Chainlink oracle.
• Daily Price Adjustment: Although the tNAV is refreshed quarterly, the market-facing price of reUSDe compounds on a daily cadence. At 00:00 UTC each day, the token’s market price is adjusted via a rebase mechanism intended to create a gradual appreciation that moves the market price toward the most recently published quarterly tNAV, minimizing abrupt price shocks and smoothing accrual for holders.

Capital Deployment and Management

Capital flows from user deposits into the reinsurance ecosystem through a defined process that leverages specialized smart contracts and regulated legal vehicles.

Minting Process

To mint reUSDe, a user submits the protocol’s senior stablecoin, reUSD, to the reUSDe smart contract. On receipt, the contract issues a corresponding quantity of reUSDe and transfers it to the depositor’s wallet.

Deployment Workflow

After minting, the backing capital follows an established deployment path into the protocol’s reinsurance arrangements.

• Allocation to Insurance Capital Layer (ICL): Deposited funds are first routed to the designated Insurance Capital Layer, a smart contract that administers capital for a particular reinsurance program.
• Deployment into Regulated Trust: The ICL subsequently places the capital into a regulated §114 reinsurance trust, a legally segregated trust vehicle commonly used in insurance to hold collateral.
• Serving as Contingent Capital: Inside the trust, these funds function as junior surplus capital, acting as contingent collateral to back the protocol’s reinsurance obligations.
