# OutStake 概览

> 把多协议生息资产，统一铸成锚定型稳定币 uAsset。

OutStake 是 Outrun 的收益基础设施。它解决一个老问题：**Aave、Lido、Sky、Ethena、Lista、Aster** 各协议的生息代币（aToken、wstETH、sUSDS、sUSDe……）各自为政，收益和流动性都被切碎。OutStake 用一层标准化接口把它们统一，再铸成可在全链流通的 uAsset 稳定币。

## 三步看懂 OutStake

1. **收资产** —— [SY 标准化收益层](/en/zh/outstake-shou-yi-ji-chu-she-shi/sy-adapters.md)把不同协议的生息代币，用统一接口包装起来。
2. **铸稳定币** —— [创世质押](/en/zh/outstake-shou-yi-ji-chu-she-shi/staking-modes.md)存入生息资产，按其当前价值面值铸出 [uAsset](/en/zh/outstake-shou-yi-ji-chu-she-shi/uasset.md)(UETH / UUSD / UBNB)，每枚锚定 1 单位底层资产；或经 [PSM](/en/zh/outstake-shou-yi-ji-chu-she-shi/psm.md)用储备资产按面值直接兑换。
3. **管起来** —— 仓位随时赎回（无锁定期、无清算），闲置 uAsset 可进 [USR 储蓄](/en/zh/outstake-shou-yi-ji-chu-she-shi/usr.md)吃利息，[一站式入口](/en/zh/outstake-shou-yi-ji-chu-she-shi/router.md)把全链路合成一次操作。

| **跨链**     | uAsset 基于 LayerZero，全链流通            | [跨链与速率限制](/en/zh/outstake-shou-yi-ji-chu-she-shi/omnichain.md)    |

## uAsset 去了哪里

uAsset 不只留在 OutStake。它是 Outrun 生态的统一价值媒介，会流向 [Memeverse](/en/zh/memeverse-quan-lian-she-qu-gong-shi-qi-dong-qi/memeverse.md)：作为 Memecoin 创世的资金、杠杆创世的利息、创世积分的支付币。OutStake 负责"铸造"，Memeverse 负责"消耗" —— 两者通过 uAsset 的供需互相咬合（收益各自独立，不互相回流，详见[增长飞轮](/en/zh/ecosystem-sheng-tai-xie-tong/flywheel.md)）。

## 为什么不直接持有 wstETH？

DeFi 用户的第一反应往往是："我直接持有 wstETH 也能拿 Lido 的质押收益，为什么要过 OutStake？" 答案在三个增量价值：

* **统一与跨链**：wstETH 只在以太坊原生；过 OutStake 后变成 UETH，基于 LayerZero 全链流通，可在任意支持的链上使用，不必各自攒流动性。
* **抵押生息不停**：创世质押后，抵押的生息资产继续生息，敞口 100% 归你 —— 拿 uAsset 去用的同时，底层收益一份不少。
* **接入 Memeverse 的门票**：UETH / UUSD / UBNB 是 Memeverse 创世、杠杆、结算的计价币。持 uAsset 可以参与[普通创世](/en/zh/memeverse-quan-lian-she-qu-gong-shi-qi-dong-qi/genesis.md)，在成功解锁后的 24 小时保护期内完成退出，以本金守恒方式博取 Memecoin 生态收益 —— 这是直接持 wstETH 拿不到的。

换言之，OutStake 不只是"换个壳持 LST"，而是把生息资产**升级成全链可用、生息不停、可接入社区启动的统一媒介**。

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.outrun.build/en/zh/outstake-shou-yi-ji-chu-she-shi/outstake.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
