Metis Hybrid Rollup development network launched... only ECC path activated

Metis has launched a hybrid rollup devnet that combines validity proofs with its optimistic rollup architecture, though only the legacy ECC verification path is currently active on the network. The disclosure, made in a technical announcement on the 11th, does not mean mainnet withdrawal times have been shortened or that quantum-resistant security is live. Optimistic rollups typically impose roughly a seven-day challenge window before withdrawals finalize, and the hybrid design aims to cut that delay by adding validity proofs. The key caveat is that the faster proof-based path remains inactive on the devnet, so the design goal is not yet demonstrated end to end. Next milestones to watch are activation of the validity-proof route on the devnet and any subsequent reduction in mainnet withdrawal latency.
