Parmigiana is now the primary public testnet for Signet. If you’re building today, use Parmigiana for all rollup + host testing.
Why Parmigiana
- Same-block atomic swaps between Ethereum (host) and Signet (rollup)
- Round-robin builder rotation for predictable block slots
- Full EVM compatibility with USD-native gas on the rollup
- Lean architecture (no proving systems, no state roots)
