Everything You Need to Know About Ethena Fi

Getting started with Ethena Fi is straightforward. Here's the step-by-step process:

• Connect a compatible Web3 wallet (MetaMask, Coinbase Wallet, WalletConnect, etc.) to the Ethena Fi app.
• Acquire USDe by swapping USDT, USDC, USDS, ETH, or other supported assets directly within the app's Swap interface, or purchase USDe from a DEX such as Curve or Uniswap.
• Once you hold USDe, navigate to the Earn / Stake tab and stake your USDe to receive sUSDe.
• sUSDe automatically compounds your staking rewards — you don't need to manually claim anything.

Note: Minting USDe directly through Ethena Fi's protocol requires eligibility verification (KYC) and is available only to approved institutional and qualified participants. Retail users can access USDe through secondary markets and DEX swaps.

Ensure you are using the official ethena-fi.icu app and always verify your wallet connection before signing any transaction.

Ethena Fi is primarily built on Ethereum mainnet, where USDe is natively issued and sUSDe staking is available. However, USDe has expanded its presence across multiple networks through canonical bridges and integrations:

• Ethereum — native issuance, staking (sUSDe), and full protocol access.
• Arbitrum — USDe is available as a bridged asset and usable in various DeFi protocols.
• Base — USDe is accessible through Coinbase's L2 network.
• Mantle — Ethena Fi has a native integration with Mantle's ecosystem.
• BNB Chain — USDe is available for DeFi usage.
• TON — Ethena Fi expanded to The Open Network, supporting a broader user base.

Important: Unstaking (converting sUSDe back to USDe) is only supported on Ethereum mainnet. Bridged versions of USDe on other networks must first be bridged back to Ethereum before unstaking.

When you stake USDe through Ethena Fi, you receive sUSDe (Staked USDe) in return. sUSDe is an ERC-4626 tokenized vault share that represents your proportional ownership of the Ethena Fi staking pool.

Here's how the yield mechanics work:

• Ethena Fi generates revenue primarily from funding rates earned on the short perpetual futures positions that hedge the protocol's collateral.
• Additional revenue comes from staking rewards on ETH and BTC collateral held within the protocol.
• This revenue is periodically deposited into the sUSDe staking contract, increasing the redemption value of each sUSDe token relative to USDe over time.
• Because the exchange rate increases, you don't receive separate reward tokens — your sUSDe simply becomes worth more USDe over time.

The APY (Annual Percentage Yield) for sUSDe is variable and depends on prevailing market conditions, particularly the funding rates on major crypto derivatives exchanges. Historically, the APY has ranged from approximately 3% to over 25% depending on market conditions.

To unstake, you submit an unstaking request. There is a dynamic cooldown period of up to 7 days on Ethereum, after which your USDe becomes available for withdrawal. Unstaking is only possible on Ethereum mainnet.

Like all DeFi protocols, Ethena Fi carries risks that users should understand before participating. The main risk categories include:

• Funding Rate Risk: If funding rates turn persistently negative, the protocol may generate losses rather than profits. Ethena Fi maintains a reserve fund to buffer against negative funding periods, but extreme or prolonged negative rates could impact the protocol's stability.
• Custodian Risk: Ethena Fi uses institutional-grade custodians (OES — Off-Exchange Settlement providers) to hold collateral. A custodian failure or insolvency could result in loss of assets held with that custodian.
• Exchange Risk: Ethena Fi holds short perpetual positions on centralized exchanges. An exchange insolvency or hack could result in loss of the margin posted to that exchange.
• Smart Contract Risk: Despite multiple audits, all smart contract code carries the inherent risk of undiscovered bugs or exploits.
• Liquidity Risk: In periods of extreme market stress, USDe may trade at a discount to its $1.00 peg on secondary markets, even if the protocol itself remains solvent.
• Regulatory Risk: The regulatory landscape for synthetic stablecoins is evolving and may affect Ethena Fi's operations in certain jurisdictions.

Ethena Fi publishes detailed risk documentation and maintains a transparency dashboard where collateral, positions, and reserve fund status can be monitored in real time. Users are encouraged to review this information before committing significant capital.

Ethena Fi generates revenue through two primary mechanisms:

• Perpetual Futures Funding Rates: When traders are net long on perpetual futures markets (which is the common state during bull markets), short position holders like Ethena Fi receive funding payments. These payments are typically positive and contribute significantly to sUSDe APY.
• Staking Rewards on Collateral: Ethena Fi holds Ethereum (stETH, wbETH, etc.) and Bitcoin as collateral. The Ethereum collateral earns native staking rewards (currently ~3-4% APY), which layer on top of the funding rate income.

The combined yield from these two sources is distributed exclusively to sUSDe stakers — users who have staked their USDe. USDe holders who have not staked their tokens do not receive yield, which creates a built-in incentive to stake and an organic demand mechanism for the protocol.

The Ethena Fi protocol maintains a reserve fund that accumulates a portion of revenue during high-yield periods, providing a buffer for times when funding rates are low or negative.

The USDe peg is maintained through a delta-neutral collateral mechanism combined with an arbitrage-friendly redemption system:

• Delta-Neutral Backing: For every $1 of USDe minted, Ethena Fi holds $1 of crypto collateral (ETH, BTC, stablecoins) and simultaneously opens an equivalent short position on a derivatives exchange. If the collateral drops in value, the short position gains an equal amount — keeping the net value at $1.00.
• Arbitrage Mechanism: Approved minting participants can always mint 1 USDe for $1 worth of collateral or redeem 1 USDe for $1 worth of collateral. This arbitrage path ensures the price reverts toward $1.00 if it deviates on secondary markets.
• Reserve Fund: A protocol-controlled reserve fund can be deployed to support the peg during stress events.

While the backing mechanism is designed to be robust, users should note that USDe is not guaranteed by any government or insurance scheme. The stability relies on the continued functioning of the protocol's hedging strategy and the solvency of its custodians and exchange counterparties.

Ethena Fi takes a multi-layered approach to security. The protocol's smart contracts have been audited by multiple reputable security firms. Audit reports are publicly available in the Ethena Fi GitHub repository and documentation site.

Key security measures include:

• Multiple independent audits from leading smart contract security firms prior to mainnet launch and major upgrades.
• Bug bounty program via Immunefi, offering substantial rewards for responsibly disclosed vulnerabilities.
• Off-Exchange Settlement (OES) custody: collateral is held by institutional custodians rather than directly on exchanges, reducing exchange counterparty risk.
• Multi-sig governance: critical protocol parameters require multi-signature approval, preventing single points of failure.
• Real-time transparency dashboard: all collateral positions and reserve fund holdings are publicly verifiable on-chain and through third-party attestation services.

Despite these measures, no protocol can guarantee zero risk. Ethena Fi recommends that users only invest what they can afford to lose and diversify their DeFi holdings.

ENA is the governance token of the Ethena Fi protocol. ENA holders can participate in on-chain governance to vote on protocol upgrades, parameter changes, risk management decisions, and treasury allocations.

Key aspects of the ENA token and governance:

• Governance rights: ENA holders vote on proposals that affect the protocol's operation, including supported collateral types, exchange counterparties, and yield distribution parameters.
• sENA (Staked ENA): ENA can be staked to receive sENA, which may provide voting power boosts and potential protocol benefits.
• Rewards eligibility: Participating in the Ethena Fi ecosystem — staking USDe, holding sUSDe, or engaging with partner protocols — may make users eligible for ENA token rewards and campaigns.
• Treasury: The Ethena Fi Foundation controls a treasury that is governed by ENA holders and is used to fund development, security, and ecosystem growth.

Ethena Fi is progressively decentralizing its governance over time, with the long-term vision of becoming a fully community-governed protocol.

Ethena Fi has built an extensive ecosystem of DeFi integrations, making USDe and sUSDe composable assets usable across the broader DeFi landscape. Key integrations include:

• Pendle Finance: sUSDe can be tokenized into yield and principal components, allowing users to lock in fixed yields or trade yield exposure.
• Aave: USDe and sUSDe are listed as collateral assets on Aave v3, enabling users to borrow against their holdings.
• Morpho: Dedicated lending markets for USDe/sUSDe with optimized interest rates.
• Curve Finance: Deep liquidity pools for USDe paired with other major stablecoins, providing efficient on-chain swaps.
• MakerDAO / Sky: USDe is integrated as part of Sky's stablecoin ecosystem.
• Frax Finance: Cross-protocol integrations supporting USDe liquidity.
• LayerZero / Stargate: Cross-chain bridging infrastructure enabling USDe to move between supported networks.

The growing ecosystem of integrations means that USDe holders have numerous options for deploying their assets to generate additional yield on top of the baseline sUSDe APY. The Ethena Fi app's Ecosystem section and the Rewards dashboard track eligible positions across these partner protocols.

Ethena Fi periodically runs incentive campaigns called "Shards" or seasonal reward programs. These campaigns reward users who contribute to the growth and adoption of the protocol.

How rewards typically work:

• Users earn Shards or points by holding USDe, staking for sUSDe, or deploying USDe/sUSDe in eligible ecosystem protocols (Pendle, Aave, etc.).
• Points are accumulated over time based on the size and duration of your positions.
• At the end of a campaign season, accumulated points may be converted into ENA token allocations distributed via airdrop.
• Multipliers are often available for users who deploy assets in certain protocols or maintain larger positions.

Rewards eligibility and campaign details are shown in the Ethena Fi app's Rewards and Overview sections. Note that reward programs are subject to change and are at the discretion of the Ethena Fi Foundation. Past rewards programs are not a guarantee of future distributions.

Always verify campaign details through official Ethena Fi channels — X (Twitter), Telegram, and the official documentation — to avoid phishing attempts.

Ethena Fi is a decentralized protocol accessible globally through the open internet. However, certain functionalities — particularly direct minting and redemption of USDe through the protocol — are restricted to approved participants and may require geographic and identity verification.

Key geographic considerations:

• Direct minting access is not available to US persons or residents of certain other jurisdictions due to regulatory requirements.
• Secondary market access to USDe (buying on DEXs, CEXs) may have different availability depending on your local exchange and jurisdiction.
• The Ethena Fi app at ethena-fi.icu may display geo-restriction notices for users in certain regions.
• Ethena Fi is not intended as an offer for the acquisition of sUSDe directed at persons with their habitual residence in the European Union or European Economic Area under certain regulatory frameworks.

Users are responsible for ensuring that their use of Ethena Fi complies with the laws and regulations of their respective jurisdictions. This FAQ does not constitute legal or financial advice.
