title: [TEMP CHECK] stEUR Onboarding on Aave V3 Ethereum Pool
author: @marczeller - Aave-chan Initiative
date: 09-10-2023
Summary
This TEMP CHECK proposes the onboarding of stEUR as a collateral-only asset on the Aave V3 Ethereum Pool. stEUR represents staked agEUR, a decentralized EUR-peg stablecoin minted by the Angle Protocol.
Motivation
-
Decentralized Stablecoin Diversity: At the ACI, we support the diversity of decentralized stablecoins. EUR stablecoins, in particular, are underrepresented in the ecosystem, and onboarding stEUR can help bridge this gap.
-
Growth in a Controlled Environment: While stEUR and agEUR have relatively small market caps (5M$ and 20M$ respectively), onboarding stEUR as a collateral-only asset with limited caps will allow it to grow in a controlled environment, minimizing risks for the Aave protocol.
-
Collateral Potential: stEUR, being a staked version of a decentralized EUR-peg stablecoin, presents a promising collateral candidate for Aave.
Specification
- Asset: stEUR
- Contract Address: 0x004626A008B1aCdC4c74ab51644093b155e59A23
Price Feed
For the price feed, we propose implementing a price adapter that calculates the value of stEUR based on the value of agEUR/USD and the exchange rate of agEUR/stEUR.
This replicates precedents such as with sDAI.
Risk Parameters
We propose the following parameters for stEUR onboarding:
| Parameter | Value |
|---|---|
| Isolation Mode | No |
| Borrowable | No |
| Borrowable in Iso | No |
| Stable Borrowing | No |
| Collateral Enabled | Yes |
| Supply Cap (stEUR) | 3,000,000 |
| Borrow Cap (stEUR) | 0 |
| Debt Ceiling | N/A |
| LTV | 70% |
| LT | 75% |
| LB | 8% |
| LPF | 10% |
| Reserve Factor | 20% |
| Base Rate | 0% |
| Slope 1 | 8% |
| Slope 2 | 80% |
| Optimal Ratio | 80% |
Next Steps
- Gather community feedback on this TEMP CHECK.
- If consensus is reached, escalate this proposal to TEMP CHECK snapshot stage.
- If TEMP CHECK snapshot outcome is YAE, escalate to ARFC stage.
- If consensus on ARFC stage is reached and risk service providers provided feedback on risk parameters, escalate to ARFC snapshot stage.
- If ARFC snapshot stage outcome is YAE, escalate to AIP stage.
