You’ve just built a functional DeFi agent! Here are some ideas to extend it:

​
Next Steps

​
Extend with AI tools

Start vibe coding with Cursor (or any AI IDE): 
cursor .  # Opens project in Cursor
Your agent’s configuration lives in the wallet config file we just edited. In Cursor, press Cmd+K (or Ctrl+K on Windows) and describe what you want:
  • “Add Uniswap integration for token swaps”
  • “Create a portfolio dashboard showing all holdings”
  • “Add quick action buttons for common operations”
  • “Show L1 and L2 gas costs separately”
Ask your AI to understand the GOAT SDK integration and then generate compatible code that works with your existing setup.

​
Want token swaps? Add Uniswap:

Goat supports a lot of plugins. See a list of all the plugins that GOAT supports here. 
npm install @goat-sdk/plugin-uniswap
Then update your plugins in wallet-config.ts: 
import { uniswap } from "@goat-sdk/plugin-uniswap";

plugins: [
  sendETH(),
  erc20({ tokens: [USDC, PEPE] }),
  uniswap({
    apiKey: process.env.UNISWAP_API_KEY // Optional, get from hub.uniswap.org
  })
]
Note : When adding plugins for GOAT always check you have the right configurations for it. For example, some plugins only work on mainnet or a particular chain.

​
Ready for mainnet?

When you’re ready for real transactions, update your configuration: 
.env.local:
RPC_PROVIDER_URL=https://arb1.arbitrum.io/rpc
# Add a mainnet private key with actual ETH
Code update in wallet-config.ts: 
import { arbitrum } from "viem/chains"; // Instead of arbitrumSepolia
