常见问题Frequently Asked Questions

Ethena USDe 是什么？What is Ethena USDe?+

Ethena USDe 是一个 delta 对冲的合成美元稳定币。它通过在永续合约市场同时做多 ETH 和做空 USDT 来实现 delta 中性，从而获得来自资金费率（funding rate）和 ETH staking 收益的回报。USDe 旨在成为首个大规模采用的透明稳定币，提供可验证的美元锚定。Ethena USDe is a delta-hedged synthetic dollar stablecoin. It achieves delta neutrality by going long ETH and short USDT in perpetual swap markets, earning returns from funding rates and ETH staking rewards. USDe aims to be the first widely adopted transparent stablecoin providing verifiable dollar pegging.

USDe 的收益从哪里来？Where does USDe's yield come from?+

USDe 的收益来自两个渠道：1) 永续合约市场的资金费率，当多头持仓多于空头时，多头支付空头，USDe 的空头仓位从中获利；2) ETH staking 收益。这两种收益来源的组合使得 USDe 能够提供相对稳定的收益，同时维持美元锚定。USDe's yield comes from two sources: 1) Funding rates in perpetual swap markets, where when there are more long positions than shorts, longs pay shorts, and USDe's short positions profit from this; 2) ETH staking rewards. The combination of these two income sources allows USDe to provide relatively stable yields while maintaining the dollar peg.

USDe 与 USDC、USDT 有什么区别？What is the difference between USDe, USDC, and USDT?+

USDe 与传统法币抵押稳定币（USDC、USDT）不同。USDC 和 USDT 由美元或短期国债 1:1 抵押，而 USDe 采用 delta 对冲策略，通过合约市场仓位和 ETH staking 来维持锚定，不依赖银行账户。这种方式更去中心化，但策略本身存在智能合约风险和市场风险。USDe differs from traditional fiat-collateralized stablecoins (USDC, USDT). USDC and USDT are 1:1 collateralized by US dollars or short-term treasury bonds, while USDe maintains its peg through delta hedging strategies using contract market positions and ETH staking, without relying on bank accounts. This approach is more decentralized, but carries smart contract risk and market risk from the strategy itself.

如何安全存储 USDe？How to securely store USDe?+

存储 USDe 最安全的方式是使用硬件钱包。硬件钱包将私钥存储在安全芯片中，完全与网络隔离。Keystone 支持所有 EVM 兼容代币包括 USDe，可通过 QR 码与 MetaMask 等钱包连接，在保持私钥完全离线的同时参与 Staking 收益策略。The safest way to store USDe is using a hardware wallet. Hardware wallets store private keys in a secure chip completely isolated from the internet. Keystone supports all EVM-compatible tokens including USDe, and can connect to wallets like MetaMask via QR codes, participating in Staking yield strategies while keeping private keys completely offline.

如果丢失 Keystone 设备，我的 USDe 还能找回吗？If I lose my Keystone device, can I recover my USDe?+

可以。Keystone 支持 BIP-39 标准助记词，你可以在任何兼容的 EVM 钱包（如 MetaMask）中恢复 USDe 资产。建议将助记词妥善保管在安全的离线位置（如 Keystone Tablet Plus 金属助记词板），作为终极备份方案。Yes. Keystone supports BIP-39 standard recovery phrases. You can recover USDe assets in any compatible EVM wallet (such as MetaMask). It is recommended to keep your recovery phrase safely stored in a secure offline location (such as Keystone Tablet Plus metal recovery phrase board) as the ultimate backup solution.
