Coinbase Hackathon Feb 1. 2025

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!

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"
