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.

System transactions

Transactions on Signet can originate from Ethereum. When the Signet node observes specific events from the Passage or Transactor contracts on the host chain, it creates corresponding transactions on the rollup.

Three host-chain event types produce system transactions:

Event	Trigger
`Enter`	ETH deposited to Passage
`EnterToken`	ERC-20 tokens deposited to Passage
`Transact`	Arbitrary execution requested via Transactor

System transactions execute last in the block, after all user-submitted transactions. Processing order within that group is:
