Chains
When using Web3GPT, you can specify the chain to interact with in the chat. This allows you to:
- Test your contracts on various testnets
- Verify your contracts automatically on block explorers
- Deploy the same contract across multiple chains
You can also switch to any supported chain in your wallet when deploying manually. Web3GPT returns a link to the configured explorer and, where available, submits the source for verification.
Polygon
-
Polygon mainnet
- Chain ID: 137
- Gas token: POL
- Block Explorer: polygonscan.com
- Deployment: supported through the Web3GPT agent and SDK flow
-
Polygon Amoy
- Chain ID: 80002
- Gas token: test POL
- Block Explorer: amoy.polygonscan.com
- Deployment: supported through the Web3GPT agent, SDK, and manual wallet flow
Polygon mainnet transactions use real POL and are irreversible. Generate and review the contract first, test the exact deployment flow on Amoy, and state either Polygon mainnet or Polygon Amoy explicitly in the prompt. See the SDK guide for a confirmation-gated example and Polygon’s official network reference for current chain details.
