Metis launches Hybrid Rollup Devnet, aiming to support post-quantum cryptography.

Metis has announced that its Hybrid Rollup is now live on Devnet. This solution introduces proof-of-validity into the existing optimistic Rollup architecture, aiming to reduce withdrawal waiting times. Metis first proposed this design at ETHDenver in March 2023, with the goal of reducing withdrawal waiting times from 7 days to the hour level. This upgrade includes two components: combining optimistic challenges with Ziren validity proofs, and decentralized sorting (DSeq) support for ML-DSA post-quantum signatures. Devnet employs a cryptographically agile design, with the codebase supporting both ECC and PQC paths. Initially, only ECC is enabled, with a later switch to post-quantum cryptography. The testnet is scheduled to launch in Q1 2027. In addition, Metis released a draft for public discussion proposing to convert OVM tokens into native assets. This draft has not yet been approved by governance, and snapshot blocks and timelines are pending.
