Alchemy Smart Wallets for Aave

Two approaches for integrating with Aave using Alchemy's Smart Wallets - Core (recommended) and Wallet APIs.

Quick Start

1. Setup environment variables:

   cp .env.example .env
   # Fill in your values in .env

2. Install dependencies:

   npm install

3. Initialize your smart wallet:

   npm run account  # Get your smart wallet address

4. Fund your smart wallet: Send 0.01+ DAI to the smart wallet address from step 3

5. Run examples:

   npm run supply   # Supply DAI to Aave
   npm run withdraw # Withdraw DAI from Aave

Environment Variables

Required in .env:

• PRIVATE_KEY - Your EOA private key (0x prefixed)
• ALCHEMY_API_KEY - From dashboard.alchemy.com
• PAYMASTER_POLICY_ID - From Gas Manager (for gas sponsorship)

Implementation Approaches

🔧 Core (Recommended)

• npm run core:* - Direct @aa-sdk/core implementation
• Simpler API, fewer lines of code

🏛️ Wallet APIs

• npm run wallet:* - @account-kit/wallet-client implementation
• Full prepare/sign/send workflow

Configuration

To customize chain, token addresses, or amounts, edit src/config.ts:

export const config = {
  chain: arbitrum,        // Change to sepolia, polygon, etc.
  amounts: {
    deposit: "0.01",      // Change deposit amount
    withdraw: "0.01",     // Change withdraw amount
  }
}

Notes

• Uses Arbitrum network and DAI token by default
• Creates smart wallets (not EOAs) - fund the smart wallet address
• Gas fees sponsored via Alchemy Gas Manager
• Get DAI on Arbitrum: Uniswap
