AAVE V3 Integration
Low-level integration with AAVE V3 protocol contracts for reading on-chain data and generating operation quotes.
Overview
This skill provides:
- Contract Interface Definitions - ABIs for AAVE V3 contracts
- Quote Generation - Scripts to get supply, borrow, repay, withdraw quotes
- APY Data - Scripts to fetch current supply/borrow APY for all assets
- Position Simulation - Scripts to preview how actions affect Health Factor and risk
- Reserve Configuration - Reading asset parameters from chain
- User Account Data - Reading user positions and health metrics

```bash npx tsx packages/plugins/aave-integration/scripts/quote-apy.ts <chainId> ```
simulate-position.ts
Simulates how an action would affect a user's position.
```bash npx tsx packages/plugins/aave-integration/scripts/simulate-position.ts <chainId> <userAddress> <action> <token> <amount> ```
