• Extends existing Coinbase plugin suite

Documentation changes needed?

My changes require a change to the project documentation.

• Added comprehensive documentation for the token contract plugin in docs/docs/packages/plugins.md
• Updated plugin documentation with new features and usage examples
• Added configuration instructions and best practices

Testing

Where should a reviewer start?

1. Review the token contract plugin implementation:

   • packages/plugin-coinbase/src/plugins/tokenContract.ts
   • packages/plugin-coinbase/src/types.ts (new token contract types)
   • packages/plugin-coinbase/src/templates.ts (new templates)

2. Review the integration:

   • agent/src/index.ts (plugin initialization)
   • packages/plugin-coinbase/src/index.ts (plugin exports)

Detailed testing steps

1. Configure Coinbase credentials:

   export COINBASE_API_KEY=your_api_key
   export COINBASE_PRIVATE_KEY=your_private_key

2. Test ERC20 token deployment:

   await runtime.triggerAction("DEPLOY_TOKEN_CONTRACT", {
     contractType: "ERC20",
     name: "TestToken",
     symbol: "TST",
     network: "base",
     totalSupply: 1000000
   });

3. Test ERC721 (NFT) deployment:

   await runtime.triggerAction("DEPLOY_TOKEN_CONTRACT", {
     contractType: "ERC721",
     name: "TestNFT",
     symbol: "TNFT",
     network: "eth",
     baseURI: "https://api.test.com/metadata/"
   });

4. Test contract interaction:

   await runtime.triggerAction("INVOKE_CONTRACT", {
     contractAddress: "0x123...",
     method: "transfer",
     abi: [...],
     args: {
       to: "0x456...",
       amount: "1000000000000000000"
     },
     network: "base"
   });

5. Verify CSV logging:

   • Check contracts.csv for deployment records
   • Verify transaction details are properly logged
