# Lending on Aave

> Compare Aave V3 yields across supported chains and use the registry-bound Base USDC deposit rail from Mission Control.

<Note>
  Aave V3 is one of the protocols in Otto's live yield discovery service. For the distinction between discovery and executable venues, see the [Earning Yield guide](/using-otto-ai/earning-yield-on-morpho).
</Note>

**Key Capabilities**

1. **Live Aave Discovery:**
   Otto reads Aave V3 supply markets and compares their net APYs across the discovery service's supported chains.
2. **Registry-Bound Execution:**
   The executable DApp rail is narrower than discovery: it accepts only the pinned **Aave V3 · Base · USDC** market, and only while the unified Otto session is `ARMED` and the discovery row matches the server registry exactly.
3. **Input Filters:**
   Discovery drops non-positive or implausible APYs, and applies a \$1 million TVL floor whenever the source provides TVL. These are data-quality filters, not a guarantee of safety or returns.

**Discovery Chains:** Ethereum, Base, Arbitrum, Polygon, Optimism, and Avalanche. **DApp execution:** Base USDC only.

**How to Lend**

1. **Open `/app` Mission Control** and inspect the **Featured Yield** card. The venue table is live discovery; rows that are not registry-backed are display-only.
2. **Check the executable row:** The deposit control targets the card's current top venue. Proceed only when it shows **AAVE V3 · BASE USDC · PINNED EXECUTION**; the venue rows are not a manual pool picker.
3. **Arm and review:** The unified Otto session must be `ARMED`. Review the venue, current APY, asset, and amount before submitting.
4. **Deploy:** Enter the USDC amount and select **DEPLOY · UNIFIED ARM**. Once the unified session is armed, the supported deposit does not ask for a second owner signature at click time.

<Note>
  The standalone **Yield Copilot** mini-agent page is discovery-only. Registry-bound deposits are live from the **Featured Yield** card for its current exact Base USDC Aave or Morpho row; auto-rebalance and alerts remain disabled.
</Note>

This integration separates broad Aave discovery from a narrowly identified Base USDC execution route.
