# Environments

> Where to find the ProofBridge app and API, on mainnet and on the soak testnet

ProofBridge runs in two environments. **Soak** is the public testnet
deployment, on Ethereum Sepolia and Stellar Testnet, with test tokens.
**Mainnet** is the production deployment.

**Soak**

| | URL |
| - | - |
| App | [staging.pfbridge.xyz](https://staging.pfbridge.xyz) |
| API | `https://api-staging.pfbridge.xyz` |

Soak runs on **Ethereum Sepolia** and **Stellar Testnet** with test tokens only.

**Mainnet**

| | URL |
| - | - |
| App | [app.pfbridge.xyz](https://app.pfbridge.xyz) |
| API | `https://api.pfbridge.xyz` |

> [!NOTE]
>
> Mainnet isn't live yet. Use **Soak** to try ProofBridge today.

Every page in these docs that links to the app or the API uses the same
two tabs. Pick the environment you're working in and the links follow.

## What differs between them

| | Mainnet | Soak |
| - | - | - |
| Networks | Ethereum, Stellar | Ethereum Sepolia, Stellar Testnet |
| Funds | real assets | test tokens from the [faucet](https://docs.pfbridge.xyz/v3/guides/faucet.md) |
| Contracts | the mainnet deployment | the testnet deployment on [Smart contracts](https://docs.pfbridge.xyz/v3/reference/smart-contracts.md) |

> [!WARNING]
>
> Never send mainnet assets to a soak address. The two deployments are
> separate, and soak contracts are redeployed from time to time.
