Contract Deployments

The Polymarket CTF Exchange is deployed on multiple networks for production and testing purposes.

​
Production Deployments

Polygon Mainnet

Network: Polygon (Chain ID: 137)Contract Address: 0x4bFb41d5B3570DeFd03C39a9A4D8dE6Bd8B8982EExplorer: View on PolygonScanThis is the primary production deployment used by Polymarket for live trading.

​
Testnet Deployments

Amoy Testnet

Network: Amoy (Polygon Testnet)Contract Address: 0xdFE02Eb6733538f8Ea35D585af8DE5958AD99E40Explorer: View on Amoy PolygonScanThis deployment is used for testing and development purposes.

Deployment Details

​
Polygon Mainnet Configuration

The Polygon mainnet deployment was initialized with the following constructor parameters:
ParameterAddressDescription
Collateral Token0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174USDC on Polygon
CTF Contract0x4D97DCd97eC945f40cF65F87097ACe5EA0476045Conditional Tokens Framework
Proxy Factory0xaB45c5A4B0c941a2F231C04C3f49182e1A254052Gnosis Safe Proxy Factory
Safe Factory0xaacFeEa03eb1561C4e67d661e40682Bd20E3541bGnosis Safe Factory
The exchange contract automatically approves the CTF contract to spend unlimited USDC, enabling efficient minting operations.

​
Deployment Process

The deployment followed these steps:
  1. Contract Creation: Deploy CTFExchange with constructor parameters
  2. Admin Setup: Add authorized administrator address
  3. Operator Setup: Add authorized operator address
  4. Role Renunciation: Deployer renounces admin and operator roles
  5. Verification: Verify contract source code on block explorer
The deployer address renounced all privileged roles after setup, transferring full control to the designated admin and operator addresses.

​
Contract Information

​
Version

The deployed contracts are built with:
  • Solidity Version: 0.8.15
  • License: MIT
  • Contract Name: CTFExchange

​
Dependencies

The exchange integrates with:

​
Security

​
Audit

Chainsecurity Audit

The CTF Exchange has been professionally audited by Chainsecurity.View Audit Report

​
Immutability

The core exchange logic is immutable after deployment. However, administrators retain the following capabilities:
  • Add/remove operators
  • Add/remove administrators
  • Pause/unpause trading
  • Register new token complements
  • Update proxy factory addresses
These admin functions are necessary for operational flexibility but do not allow modification of core trading logic or user funds.

Interacting with Deployments

​
Using Web3 Libraries

import { ethers } from 'ethers';

const EXCHANGE_ADDRESS = '0x4bFb41d5B3570DeFd03C39a9A4D8dE6Bd8B8982E';
const provider = new ethers.providers.JsonRpcProvider('https://polygon-rpc.com');

const exchange = new ethers.Contract(
  EXCHANGE_ADDRESS,
  CTFExchangeABI,
  provider
);

​
Using Foundry

# Cast call to read contract state
cast call 0x4bFb41d5B3570DeFd03C39a9A4D8dE6Bd8B8982E \
  "isValidNonce(address,uint256)" \
  "0xYourAddress" \
  "1" \
  --rpc-url https://polygon-rpc.com
For testing purposes, use the Amoy testnet deployment to avoid spending real MATIC on transaction fees.

Building from Source

To build and test the contracts locally: 
# Clone the repository
git clone https://github.com/Polymarket/ctf-exchange.git
cd ctf-exchange

# Install Foundry (if not already installed)
curl -L https://foundry.paradigm.xyz | bash
foundryup

# Run tests
forge test

# Run tests with verbosity
forge test -vvv
The project uses Foundry for development and testing. Make sure to run foundryup regularly to keep your Foundry installation up to date.
