# Parmigiana quickstart

**Parmigiana Testnet Network Configuration**

| Property | Value |
|----------|-------|
| Host Chain ID | 3151908 |
| Rollup Chain ID | 88888 |
| Deploy Height | 0 |
| Native Gas Token | USD |
| Rollup RPC | https://rpc.parmigiana.signet.sh |
| Host RPC | https://host-rpc.parmigiana.signet.sh |
| Rollup Explorer | https://explorer.parmigiana.signet.sh |
| Host Explorer | https://explorer-host.parmigiana.signet.sh |

Parmigiana is Signet's public testnet for rollup and application experimentation. This page contains the faucet, RPC endpoints, and contract addresses you need to get started.

These constants are also available to Rust code via the [`signet-constants`](https://docs.rs/signet-constants/latest/signet_constants/) crate. If you need to test applications that interact with both host and rollup chains, [please reach out](mailto:hello@init4.technology).

**Get testnet funds:** Request test USD from the [Parmigiana Faucet](https://faucet.parmigiana.signet.sh)
