stEUR is a staked version of agEUR earning a native Euro yield paid in agEUR.
In this guide, we explain how you can use the Angle app to start being exposed to this yield.
For a high level overview of how stEUR works, you can check this video.
Swapping or Staking to stEUR
While stEUR can only be minted by staking (without slippage) agEUR in a contract, the Angle app enables getting stEUR from any token.
What happens under the hood is that the app page to get stEUR integrates Odos routing technology to make the trades from any token to stEUR efficient.
When coming with agEUR, the app modal remains the same (and displays slippage elements) even though this is not relevant for agEUR<->stEUR trades. So you can disregard this information in the case where your input token is agEUR.
Getting stEUR from agEUR
Note that the exchange rate between agEUR and stEUR:
is not 1 to 1 and increases over time. So it's normal if the app shows less than 1 stEUR for agEUR provided
depends on the chain on which you're doing the trade. The value of stEUR is not uniform across all chains.
If you want more details on how Odos swaps work within the context of Angle app, check out this guide about getting agEUR.
Like for the staking part, the app enables, using Odos technology, unstaking stEUR to agEUR and in the same transaction swapping it to any token of your choice.
As there is no lock-up on the stEUR contract, unstaking can be done at any time and without any prior notice without giving away any of the yield accumulated.
Estimating potential earnings
The app provides some additional info to all agEUR stakers. If you want to estimate how you could be earning from an amount of agEUR staked or from any token swapped to stEUR, just input this amount, and the app will show you how it's going to impact your yearly earnings.
