Devnet is now live: Metis Hybrid Rollup introduces validity proofs and post-quantum signature support

Odaily reports that Metis Hybrid Rollup has launched on Devnet. The solution introduces validity proofs into the existing optimistic Rollup architecture, shortening withdrawal wait times by verifying execution results on-chain. This upgrade includes combining optimistic challenges with Ziren validity proofs, as well as decentralized sequencer (DSeq) support for ML-DSA post-quantum signatures. The Devnet codebase simultaneously supports both the ECC and post-quantum cryptography (PQC) paths, with only ECC enabled initially, after which modules will be switched to PQC one by one; the testnet is planned to launch in Q1 2027 to demonstrate both verification paths and further test the upgraded architecture. Metis has also published a public discussion draft proposing to convert the OVM Token into a native asset; the draft has not yet been approved through governance, and the snapshot block and timeline remain to be determined.
