# Crosschain Aave deposit prompt

> Prompt an AI agent to wire a one-tx Crosschain swap-and-deposit into Aave via Delta.

## Outcome

A single user signature kicks off a **Crosschain Delta** order: source token on chain A is swapped to USDC on chain B, then immediately deposited into Aave v3 on chain B. The user pays no gas on either side.

## Prompt

<CodeGroup>
  ```text Claude Code theme={null}
  You are building a React component that runs a Velora Crosschain Delta flow with a post-fill action hook into Aave v3.

  Requirements:
  - The user holds (say) USDC on Polygon. They want to end up with aUSDC supplied to Aave v3 on Base. One signature.
  - Use Velora's Crosschain Delta V2 API. Endpoints: `GET /v2/quote` (with `mode=DELTA` and `destChainId` per [Crosschain Delta docs]), `POST /v2/delta/orders/build`, `POST /v2/delta/orders`.
  - Always set `partner` to the host app's partner identifier on every quote call (`my-app-name` is only a placeholder).
  - The winning fill resolves on Base; you provide a post-fill calldata hook that calls `aavePool.supply(USDC, amount, user, 0)` against Aave v3's Base pool address.
  - Read the Aave v3 pool address from a constants file (do NOT hardcode in component code).
  - Surface clear status: "Quoting" → "Signing" → "Filling on Base" → "Depositing into Aave" → "Done".
  - On failure at any stage, return the user to a recoverable state. Cancel the Delta order if it hasn't filled.

  Reference these docs and follow them exactly:
  - https://velora.xyz/docs/delta/overview
  - https://velora.xyz/docs/delta/crosschain-delta
  - https://velora.xyz/docs/api-reference/delta/quote
  - https://velora.xyz/docs/api-reference/delta/orders-build
  - https://velora.xyz/docs/api-reference/delta/orders-submit

  Do NOT chain the Aave deposit as a separate signed transaction; it must be part of the Delta fill. Do NOT skip the order-status poll between fill and deposit.

## End-state check

* One signature from the user. No gas paid on either chain.
* Aave on Base shows the supplied position under the user's address.
