Description Coinbase Hackathon Quadruped Configuration

The Frenchie quadruped has support for a Coinbase wallet. The dog's Sepolia Base Testnet account is 0xbB568962CF24d4CeBBf5d48308aCdAE873B93202. You can check Frenchie's account balances using Coinbase's blockexploer:

https://sepolia.basescan.org/address/0xbB568962CF24d4CeBBf5d48308aCdAE873B93202

To send Sepolia Base ETH to Frenchie, you can set up a Coinbase wallet on your phone or on Google Chrome. Then request Sepolia Base ETH from a friend or the Coinbase developer faucet. Finally, send some Sepolia Base ETH to Fenchie, and see what she does!

How it works

The agent tracks the balance of testnet ETH in a Coinbase wallet and sends a message when there is a new transaction. The agent can be instructed via the prompt to express appreciation for receiving tokens. See /config/coinbase.json for an example for how this is done:

"system_prompt": "
...
You like receiving ETH. If you receive an ETH transaction, show your appreciation though actions and speech.
...
4. If there is a new ETH transaction, you might:\n    Move: 'shake paw'\n    Speak: {{'sentence': 'Thank you I really appreciate the ETH you just sent.'}}\n    Face: 'smile'\n\n
...",

The Coinbase wallet currently supports Base Sepolia and Base Mainnet networks. The Coinbase Wallet integration requires the following environment variables:

  • COINBASE_WALLET_ID: The ID for the Coinbase Wallet.
  • COINBASE_API_KEY: The API key for the Coinbase Project API.
  • COINBASE_API_SECRET: The API secret for the Coinbase Project API.

The API_KEY and API_SECRET are generated from the Coinbase Developer Portal by navigating to the "API Keys" tab and then clicking "Create API Key". If you don't already have a Developer-Managed Wallet, you can create one by following these instructions with the API key and secret you just created. Then, you can get a Wallet ID from the created wallet.

These keys are all strings and should look like this:

COINBASE_WALLET_ID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
COINBASE_API_KEY="organizations/your-org-id/apiKeys/your-api-key-id"
COINBASE_API_SECRET="-----BEGIN EC PRIVATE KEY-----\nyour-api-key-private-key\n-----END EC PRIVATE KEY-----\n"
