-## Deployment
+> All Polymarket smart contract addresses on Polygon

-The CTF contract is deployed (and verified) at the following addresses:
+All Polymarket contracts are deployed on **Polygon mainnet** (Chain ID: 137). This is the single source of truth for all contract addresses used across the platform.

-Polymarket provides code samples in both Python and TypeScript for interacting
-with our smart chain contracts. You will need an RPC endpoint to access the
-blockchain, and you'll be responsible for paying gas fees when executing these
-RPC/function calls. Please ensure you're using the correct example for your wallet
-type (Safe Wallet vs Proxy Wallet) when implementing.
