# d2Earn **Fixed-term USDC lending to the D2 Finance platform. Deposit USDC, earn a fixed yield, withdraw at epoch end.** d2Earn is a credit product, not a strategy vault. Depositors lend USDC to D2 Finance, which uses the capital as margin across its derivatives strategies on Derive and Hyperliquid. At epoch end, depositors receive principal plus the fixed yield quoted at epoch open. {% hint style="info" %} **This is not an investment in D2's strategies. It is credit exposure to the D2 Finance platform.** You earn a fixed rate agreed at deposit, not a share of strategy P\&L. {% endhint %} *** ### How d2Earn Works d2Earn is an ERC-4626 vault with a fixed-term, fixed-yield structure. 1. **Deposit.** You deposit USDC during the funding window and receive vault shares representing your claim. 2. **Lock.** At epoch start, capital is locked. D2 borrows the pooled USDC and deploys it as margin on Derive. 3. **Earn.** During the epoch, D2 runs its strategies. Your yield target is fixed at epoch open and does not vary with strategy performance. 4. **Withdraw.** At epoch end, 100% of deposits are liquid for withdrawal at NAV (vault share ratio), with accrued yield. 5. **Rollover.** Positions automatically roll into the next epoch at the newly posted rate unless withdrawn. Rates for the next epoch are posted prior to lockup. Unlike D2's Alpha Strategy vaults (HYPE++, d2HYPE, ETH++, etc.), d2Earn depositors take **no direct market exposure**. Yield is a fixed term fixed rate from D2, not a distribution of trading P\&L. *** ### Where the Yield Comes From D2's derivatives strategies generate alpha above their cost of capital. The spread between strategy alpha and the d2Earn rate is retained by D2. This is the same financing logic multi-strategy funds like Citadel and Millennium use: borrow capital at a fixed cost, deploy it into alpha-generating strategies, pay the lender, keep the spread. {% hint style="info" %} **Why D2 Finance strategies borrow from d2Earn vs deploying additional strategy capital** D2's existing strategies hold capital that may appear idle between deployments, but this capital functions as margin buffer — it protects open positions against volatility spikes, funding shocks, and adverse market moves. Redeploying it into opportunistic trades would reduce the safety margin on the core book and drift the strategy's mandate. d2Earn solves this by introducing a structurally separate pool of fixed-cost term capital. Strategy capital continues to protect the strategy; d2Earn capital funds incremental opportunistic trades when market dislocations clear the fixed borrow cost. Each pool has a defined role, each counterparty receives exactly the return profile they signed up for, and losses in one sleeve cannot cascade into the other. This structure mirrors how multi-strategy funds have used prime brokerage financing for decades: maintain a baseline book on equity capital, hold committed credit lines for episodic opportunities, and evaluate each incremental trade as a binary hurdle-rate decision against the fixed cost of funds. d2Earn brings the same primitive on-chain, with known counterparty exposure, and verifiable overcollateralization. {% endhint %} D2 only draws from d2Earn when incremental margin is expected to generate returns materially above the fixed borrowing cost. d2Earn depositors earn the posted yield either way. You're funding optionality, not directional exposure to any single strategy. {% hint style="success" %} **Target yield: 6% APR** for the initial epoch — roughly 3x the current Aave USDC supply rate. Long-term target: \~2x Aave variable rate. {% endhint %} *** ### Counterparty Transparency d2Earn is designed to be the most verifiable credit product in DeFi. You are lending to a single identified platform, and you can verify the collateral yourself. **What is observable on-chain:** * The d2Earn vault on Ethereum (ERC-4626) * D2's Derive account address holding deployed margin * D2's broader platform holdings across Aave, Hyperliquid, and Derive * All D2 strategy vault NAVs and positions **What is not observable on-chain:** * D2's Flowdesk OTC positions * D2's intraportfolio positions **Coverage context:** This is informational, not contractual. D2's on-chain assets are publicly visible but are **not legally pledged or ring-fenced** to d2Earn depositors. You have no contractual seniority over D2's other counterparties. **On the roadmap:** D2 plans to integrate third-party ZK-proven solvency attestation (via providers such as Accountable) to provide continuous, cryptographically verified proof of assets versus liabilities. Prospective, not live at launch. *** ### Risk & Counterparty Details d2Earn is a lending product with real risk. The points below are not exhaustive — read the [disclaimers](https://gitbook.d2.finance/faqs-and-disclaimers/disclaimer-and-restrictions) before depositing. #### Counterparty / Credit Risk You are taking credit exposure to D2 Finance, not market exposure to D2's strategies. If D2's balance sheet is severely impaired, you may not receive full repayment of principal or yield. There is no automated liquidation mechanism protecting depositors. D2's visible on-chain assets are informational, not contractually pledged. #### Structural Protection, Not a Guarantee D2's platform AUM sits at a large multiple of the d2Earn cap. While historical VaR simulations since 2023 indicate an extremely low probability of impairment, this AUM provides a structural cushion rather than contractual seniority. In adverse conditions (such as tail events, correlation breakdowns, liquidity shocks, forced liquidations at the venue level, or hacks) losses may exceed this collateral buffer and result in a partial or total loss of principal. #### Venue Risk Margin capital is deployed on Derive. Exchange insolvency, smart contract exploit, oracle failure, or withdrawal restrictions at the venue level could impair recovery of margin and, by extension, d2Earn repayment capacity. #### USDC Risk d2Earn is denominated in USDC. USDC itself carries issuer and depeg risk. A USDC depeg would directly impact deposit value regardless of D2 platform performance. #### Smart Contract Risk d2Earn contracts have been audited by Paladin and Cyfrin. Audits reduce but do not eliminate risk. Undiscovered vulnerabilities, oracle failures, or integration exploits may result in loss of funds. #### Liquidity / Epoch Risk Capital is locked for the full duration of each epoch. You cannot withdraw early. At epoch end, 100% of deposits become liquid for withdrawal at NAV. NAV is the ERC4626 vault exchange ratio. #### Regulatory Risk Derivatives and pooled yield products face evolving regulation across jurisdictions. Product terms, geographic availability, or eligibility may change. d2Earn is not available to restricted persons — see disclaimers. {% hint style="warning" %} **Worst case: you could lose some or all of your deposit.** d2Earn is not a savings account, not a stablecoin, and not principal-protected. It is a fixed-term credit instrument for users who understand the counterparty exposure they are taking. {% endhint %} *** ### d2Earn vs D2 Strategy Vaults | | d2Earn | Alpha Strategy Vaults (HYPE++, d2HYPE, etc.) | | ------------ | --------------------------------------------------------------------------- | ----------------------------------------------------- | | Product type | Fixed-term credit | Strategy exposure | | Return | Fixed rate, known at epoch start | Variable, based on strategy P\&L | | Risk type | Counterparty credit risk on D2 | Market risk on underlying strategy | | Upside | Capped at fixed rate | Uncapped participation in strategy alpha | | Downside | Credit loss if D2 cannot repay | Strategy drawdown | | Best for | Depositors wanting predictable yield with transparent counterparty exposure | Depositors wanting direct participation in D2's alpha | *The two products are designed to be composable. A 50/50 or 80/20 allocation across d2Earn and an Alpha Strategy vault lets depositors construct a yield barbell — fixed income on one leg, strategy alpha on the other.* *** ### FAQ **Is d2Earn a stablecoin?** No. You deposit USDC and receive USDC back. d2Earn issues ERC-4626 vault shares representing your claim, not a transferable stable asset. **Is my principal protected?** No. d2Earn is a credit product. Principal is subject to D2's ability to repay at epoch end. **Can I withdraw early?** No. Capital is locked for the epoch duration. At epoch end, 100% of deposits are liquid at NAV. All depositers exit at same vault exchange ratio. **What happens if D2's strategies lose money during the epoch?** Your yield remains contractually fixed, but D2's ability to repay depends on overall platform solvency. Strategy losses do not flow directly to d2Earn depositors unless they are severe enough to impair D2's ability to repay. **How is the rate set?** The rate is set by D2 at the start of each epoch based on expected alpha above cost of capital and posted prior to lockup. It does not change during the epoch. **Where does my USDC physically go?** Into the d2Earn ERC-4626 vault on Ethereum, then to D2 for deployment as margin on Derive. The Derive address is publicly verifiable. {% hint style="success" %} All APRs and Performance displayed on D2 Finance front end are net of fees {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
