# Contract Addresses \[Deployed Newton Protocol contract addresses across all supported networks]

This page lists all deployed Newton Protocol contract addresses. Use these when configuring the SDK, interacting with contracts directly, or verifying deployments.

When code or examples refer to `NEWTON_TASK_MANAGER`, use the `NewtonProverTaskManager` address for your target network.

## Ethereum Mainnet (Chain ID: 1)

:::warning
Ethereum mainnet contracts are deployed but require coordination before production use. Mainnet policy usage requires allowlisting by the Newton team. Before deploying or using policies on mainnet, [reach out through the intake form](https://newton.xyz/intake-form).
