Parmigiana Quickstart

How to build on Signet’s latest public testnet (Parmigiana).

Parmigiana Testnet

Host Chain ID 3151908

Rollup Chain ID 88888

Deploy Height 0

Native Gas Token USD

RPC Endpoint rpc.parmigiana.signet.sh

Rollup Explorer explorer.parmigiana.signet.sh

Host Explorer explorer-host.parmigiana.signet.sh

TX Cache API transactions.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 crate. If you need to test applications that interact with both host and rollup chains, please reach out.

Building Blocks

Bridging: Use Passage to bridge ETH/USDC/USDT/WBTC; use Transactor for L1-triggered transactions.
Orders: Follow Working with Orders, Solidity Orders, and Rust Orders with Parmigiana RPC/chain IDs swapped in.
SDKs: Rust crates in signet-sdk and examples in signet-orders; Solidity patterns in signet-sol.
Node: Install and run via signet-node using the same steps as in Install & Run a Node; point configs/env vars to Parmigiana RPC and chain IDs.
EVM behavior: See EVM Behavior (USD native, inherited headers, disabled blob opcodes, RIP-7212 precompile).
